Katarina Couteau
"I see. But before I lose control of my personality, let me tell you something. I mastered many styles of martial arts but I should not use them against you. Because each martial art is a respectable product of human technique. Techniques that should not be used through the anger. Therefore, I must send myself to my anger and use pure violence as an animal rather than a human!"



Katarina Couteau, born as Elesis Du Tirial, is the main heroine (sometimes as Anti Heroine due to her dark personality) protagonist in the LOTM: Sword of Kings storyline created by DestroyerSubjugator90. She is the adoptive granddaughter of Iruka and Haruko Couteau, the daughter of Mikaela Du Tirial and Sir Isaac Ray Peram Westcott, the older sister of Alisa Ray Peram Westcott, the older adoptive sister of Eugen Katsuragi (Vira), the wife of Myouri and the mother of Rinslet Walker Couteau.

Cheerful, courageous and also a bit naive and dimwit, Katarina is an ExKrieg originally sent to Earth as an infant with the mission to destroy it since her race was enslaved by Deus.Ex.Machina Industries Empire and were forced to invade and destroy all living being of the planet in order to give it to DEM to sell, however, after the ExKrieg Genocide caused by Isaac Westcott, Katarina was sent to Earth by her mother, Mikaela Du Tirial, to save her from being killed by DEM Forces. However, an accident alters her personality, causing her to grow up with split personality and later become Earth's greatest defender against evil forces like Mafusa Gang, KnightWalker Family, Novosic Kingdom, Godom Empire and Order of Terror as well as the informal non-official leader of the New Republic of Deus.Ex.Machina Industries. Throughout her life, she trains hard and strives to be the greatest warrior possible, while at the same time using her amazing strength and skills to uphold peace.

After her arrival on Earth, she was adopted by a french couple known as Iruka Couteau and Haruko Couteau. Due to a car accident that happened when she was a child, her adoptive parents died, forcing her to live alone in the wilderness for much of her young life, during her time alone, she suffered bullying, torture and psychological abuse by the hands of bullyings and bad people from society that judged her as a criminal, gangster and thug because of her scarlet hair (which favored her mental insanity) and became an outcast with misanthropic tendencies (hatred of humans). At one point after her corruption by the society, she thought about wiping out all humans from the planet which could have awakened her dark personality and would eventually destroy the world with Abyssal powers, however, La Folia Rihavein met her before it could happen and stopped her insane rampage with her pure-heart.



After meeting La Folia and learning about the good parts of humanity, Katarina's life was forever changed and led to her becoming a legendary warrior who saved the planet Earth many times on the future from the hands of Eckidina KnightWalker, B1-Killer Kampfdroide Unit-CM 130, Sasha, Emperor Tathagata Killer, King Hamdo, Kanon Rihavein, Aki Honda, Diabla the Qliphoth Tyrant and Junko Enoshima. In the following years, she became a prodigal warrior who saved not only the Earth but the existence and Multi-Universe from the likes of Darth Hades, Leohart the Prince of Hell, and The Fallen in her journey to become the strongest fighter warrior alive to protect all living beings. As the years passed, her mental illness ceased to exist and she became a incorruptive warrior, yet that does not mean she left most of her enemies alive, Katarina loved to fight she never left one of her most cruel enemies alive after her fight with Aki Honda, where her goodness was the reason why her adoptive sister, Eugen Katsuragi, was killed by the ruthless hands of Aki Honda, the deceased leader of Mafusa Gang.

Due to her bravery and courage, Katarina was called by Reality Council to fight and protect the Multi-Universe alongside billion of heroes that were called from many parts of the Multi-Universe to fight the Balam Alliance that were breaking havoc many universes, dimensions, multiverses, galaxies and planets of the existence, when the war against the Dark Empires from Balam Alliance was coming to an end (with the defeat of the heroes and all heroic factions), the Reality Council had no choice but to bring heroes from many parts of the existence to fight and protect all creation from the hands of the evil Sith Empire, Triggers Hell and Deus.Ex.Machina Industries Empire, alongside many heroes, Katarina was just one of them but later becomes the most notable of them all because of her trace of Abyssal and ExKrieg in her blood and had power to defeat the most powerful beings on the Multi-Universe; Darth Hades, Leohart and the Fallen, whom are the emperors of the Balam Alliance.

Initially believed to be an Earthling, she is later revealed to be a member of an extraterrestrial warrior race called the ExKriegs with the birth name Elesis Du Tirial. As Katarina grows up, she becomes the Earth's mightiest warrior and protects her adopted home planet from those who seek to harm it, she later becomes the most powerful warrior of Earth after her fight with Aki Honda and Michael Langdon that awakened her power little by little due to her injuries and horrible psychological experiences through her life. Katarina is depicted as carefree and cheerful when at ease, but quickly serious and strategic-minded when in battle, despite her cheerful personality, she is quite ruthless and sometimes can act very brutal due to her generic ExKrieg blood, in which the entire race was bloodthirsty warriors destroying entire lives on many planets. She is able to concentrate her ExKrieg and Abyssal energy and use it for devastatingly powerful energy-based attacks, the most prominent being her signature is " Pylóna tis Agonías ", ( Αγωνίες Πυλώνα tis, "Pillar of Agony" in Greek ) in which Katarina launches a dark red energy blast from her right hand and eradicate all evil beings of the existence. Despite her brutal and sociopathic nature that appears in times, Katarina is actually pure of heart who seeks to bring peace and protect the people around her, she vowed to herself to fight only to protect her friends and loved ones but as more powerful enemies appeared on the way, she unconsciously started to fight to protect not only her friends but entire planets and universes, gaining many friends and allies on the way. With her friends, she fought many villains who sought to bring war, death and destruction in many places of the Multi-Universe.

As the protagonist, Katarina appears in most of the episodes, spinoffs, specials and crossover of the storylines of CIS Productions. Due to her role in the story, Katarina has become one of the most recognizable characters by all members of CIS Productions website. Despite that, Katarina is somehow a contraversial character because of her mental Illness and split personality that turns her into a psychopathic murder, insane sadistic assassin and a brutal homicidal fighter, and because of that Katarina has an Anti-Heroic personality a good-hearted and another personality with a cold and evil heart with homicidal tendencies.

"# - 0" Tropes

 * 100% Adoration Rating: A non-intentional example. Because of her status as the Legendary ExKrieg she is worshipped by many people, however, 99% of all those people don't even know how she is or even if she is a man or a woman. It's like worshipping a person you can probably meet in the streets at random occasions.

"A" Tropes

 * Accidental Hero: Whenever Imperia or [insert character here] does something monumentally stupid, it inevitably tends to create or worsen whatever ongoing crisis situation will then have to be solved. Whenever Katarina does something monumentally stupid? It works out for the best.
 * Accidental Murder: Katarina killed many people indirectly in her past when she beat many Mafusa Gangsters, causing Aki Honda to unleash her wrath upon her subordinates, of course killing them. For a more direct example, she accidentally impaled Azul Jissele during the final battle with the MPS in Paris when Vira forced to go through nightmares.
 * Accidental Pervert: To a male example. Because of her masculine behavior, she may totally forget she is a woman and enter in the man's bath while every single male member of the Rogues are there. Oh well...
 * The Ace: Made abundantly clear since the early parts of Saga AA to Ratatoskr. She learns techniques just by watching them once or twice, and become immunes to them since he knows how to counter them. Within a few years, her martial art skills surpasses all her friends, including Tomas, and wins the Diabla the Qliphoth Tyrant in a hand-to-hand fight. She then finds out why she's able to do all these things when it's revealed that she's an ExKrieg, who are a race that is born for battle. Even that doesn't fully explain how she's able to defeat members of her race considered to be elites and even royalty, defeat and/or kill seemingly invincible aliens and monsters, achieve all the available ExKrieg transformations and even go beyond godhood. She's so good that everyone defers to her to solve the problem of the current arc, even if she isn't the strongest at that moment.
 * Action Girl: A powerful, skilled and strong young mature girl who can kick ass of bad guys around.
 * Action Mother: Even 5 billion years later after she saved the Multi-Universe and Omniverse multiple times, Katarina became a mother, threats still come to her homeworld (in fact, more of them), so she has to keep training to make sure she was powerful enough to stop it. Though, considering her Blood Knight tendencies, she'd have done so even if that wasn't the case.
 * Action Survivor: Katarina was once a normal high school student living in extraordinary times and only becomes badass because circumstances force her to.
 * Adaptational Badass: The original concept of Katarina in Season 1 was entirely a sloopy, lazy and somehow stupid character, first starting by giving her own school uniform to Megumi and going to her school with only panties and bra in public. In season 2, her character is far more composed and even more Anti-Heroic than before. Yet, her sloopy and naive personality still there, and is more used in Played For Laughs times.
 * Adaptational Intelligence: Some interpretations make her smarter than the Book Dumb fight magnet she usually is. Prior her fight with Aki Honda, she was a idiotic character who only cared to fight without thinking in battle plans. In season 2, she broken her character with her battle with Heis, which proved her to be a strategical and manipulative chessmistress in the battlefield.
 * Adaptational Nice Girl: In season 2 onwards again. The Season 1 tends to play-up her heroic side while somewhat downplaying her less noble aspects that are present in the Season 1. A prominent example is after the fight with Aki Honda, when Katarina convinces her to redeem herself; while in Season 2 she will not let any chances for her enemy to live, no matter who he or she is. In season 1, she was more rude but was able to show compassion for all living beings, including a scum-bag like Aki Honda. However, in season 2, her character is far more positive in all means but she lost completely her sense of love and mercy for her enemies.
 * Adaptational Jerkass: As aforementioned. She will kill any of her opponents in the current time of the story, even if they are children.
 * Adaptation Personality Change: She suffers a mild case of this. CIS tends to portrayal her as more heroic than her Season 1 counterpart. Katarina is still a good person in stories, but season 1's version of the character is more selfish, self-centered, and prone to overconfidence. Her level of childishness also varies. Season 1 tends to downplay her immaturity and make her fun-loving while being somewhat dense and clueless, while CIS sometimes play up his childishness and naivety for comedy.
 * Adaptational Superpower Change: In the original concept, Katarina was suppose to be able only to control her ExKrieg's bloodline abilities. For better words, only powers of her biological mother, Mikaela Du Tirial. When the story was out, she was able to control her Abyssal energy more than her ExKrieg's bloodline. However, her Abyssal power only came out in moments of despair and agony, and always resulted in her being possessed by her Evil-Alter Ego, Elesis Du Tirial.
 * Adorably Precocious Child: As a kid. By the age of 12 she was living by herself in the wilderness and cold Japanese society when her parents died.
 * Adult Fear: Few things get Katarina genuinely agitated, but the wellbeing of hierfriends and especially her family is definitely one of them. Katarina may run off on them to go training, but if they are threatened Katarina clearly starts to lose her cool. Multiple times during her time in Prime Earth, it was seeing La Folia in danger that flipped Katarina's usually hard to push temper switch. In fact, while Asuha's death is usually credited to being Katarina's trigger into Legendary ExKrieg, it was also Aryana threatening Imperia right afterwards that was the final straw for Katarina.
 * Aesop Amnesia: Zigzagged. If Madness Sub Arc is any indication... Katarina still hasn't learned her lesson in not giving murderous villains like Petelgeuse Romanne-Conti a Last-Second Chance just so he can get a rematch and a better challenge. Curiously, Katarina did not spare any of her previous enemies until she defeated Petelgeuse... And of course, giving him a second chance only resulted in more of her friends being harmed just like her fight with Aki Honda, when the ruthless gangster impaled her sister, Eugen Katsuragi.
 * Aggressive Negotiations: And not of the passive-aggressive sort, but rather of the "Do as I say, or I'll kill you here and now!" way.
 * All-Loving Hero: Forgives non-brutal enemies? Most story arcs involve this. She does not hold grudges period. Turns enemies into friends? This is how she makes friends, like the case with Oriax. Once the fight is over, anyone, even last season's enemies, are affectionately embraced as friends if they can stop trying to kill her and her crew or take over the world long enough. In addittion, she is a easy-going girl with a talent mind for stupid yet laughable moments.
 * All Up To You: When she was captured by Vira and became a Black Demon, it was Imperia who assumed the role of The Ace of the Rogues' team.
 * All Your Powers Combined: One of her signature technique, the Pillar of Agony, is an energy attack that combines the energy of every living creature around and even beyond into one big pillar of black matter.
 * Almighty Janitor: She'd merely be a lowly soldier if she was raised as an ExKrieg. That said, she becomes one of the most powerful beings in the existence. For the people of Earth, she is this as well. Outside of the Arena Simulator Battle and other circles, the general public doesn't know who she is.
 * The Aloner: For most of her life, she was a lonely girl.
 * Alternate Identity Amnesia: Katarina has no memory of her time as a Berserk during the battle of Aldegyr Kingdom. It's not until she sees Elesis transforms that she realizes that she's the monster who destroyed most of Aldegyr Kingdom.
 * Angrish: After Kanon Rihavein murders La Folia Rihavein before her eyes, Katarina becomes so stricken with anger and grief that she can barely form a sentence.
 * And This Is For...: When she fights Ara Astaroth, she does this for all of her friends whom Ara killed, including Mash.
 * Animal Battle Aura: Her aura sometimes takes the form of a Chinese Dragon, like the punch she uses to kill Diabla the Qliphoth Tyrant. This comes from her Abyssal's biologic energy, as her father, Isaac Westcott, is a Prime Abyssal.
 * Anti-Heroine: According to Subjugator, Katarina was originally supposed to be a selfish heroine to the point that one would wonder if she was actually a good person since she only grew stronger to fight strong people, not to protect anyone and some of Katarina's more heroic qualities were heightened in the Season 2. This, however, is Downplayed since even in the original concept Katarina experienced a subtle Messiah Creep where she shows more concern for the world, a willingness to sacrifice herself, and worries about people depending on her too much to the point that she boarders on being an Ideal Hero and is treated like a messiah among those who knows her. It's only her Blood Knight tendencies that can override her common sense, something she fully acknowledges, that makes her remotely close to being an anti-heroine. Katarina herself explained this further when she tells Kotori that she was never really aware of saving the world and she grew stronger to fight strong guys, but she can't sit back while other people suffer... Simply because she can't due to her humanity that refuses to allow innocent people dying or suffering in front of her. At times, Katarina may hid her worries for the world.
 * Anti-Antichrist: Hell! She is the daughter of the most evil being in the omniverse, Isaac Ray Peram Westcott, the ruthless dictator of DEM Empire, a nazi-facist empire that controls over trillions of universes! Worse, she has the bloodline of a brutal ExKrieg running through her veins. She had everything to become one of the most evil villains of the existence. Yet, she does NOT agree with any of the things her parents did in life.
 * Arch-Enemy: Countless... A lot... Oh! A LOT! Maybe too many to be listed. But this is only natural since Katarina is one of the strongest heroines ever and will always have a hand in a heroic quest to stop the villain's plan. Michael Langdon and Heis feel like that towards her.
 * Asleep for Days: During the Season 1. When she defeated Aki Honda, she went into coma for 1 week due to her first time using the Abyssal energy.
 * Assassin Outclassin': The MPS hires Jessica Bailey to take her out and steal her heart to study her ExKrieg and Abyssal energy. Katarina survives the first fight, and later beats Jessica in a rematch.
 * Asskicking Equals Authority: Lucas Kellan names Katarina captain of the the Rogues team after Tomas' death at the end of Madness Sub Arc purely based on Katarina  being the strongest mortal fighter in her planet. Azul is not happy about that. However, Katarina relents to this title to Imperia, although Katarina is still stronger than her.
 * Attractive Bent-Gender: Weaponised with the Gender spell of Andr, which transform her into a handsome man with long red hair. Her appearance as man is one of the reasons why the Princess of Minecraftia, who were suffering from the lack of males due to a disease that wiped out all masculine mobs from the world, shake the entire kingdom searching for her... Or better for him.
 * Awesomeness by Analysis: On the flip side, Katarina is also an expert at analyzing the battle strategies of her opponents and figuring out logical weaknesses and openings. This is most visible in her fights with Heis and Ara, who's about equal to her in terms of power but never bothered to develop the same understanding of combat that Katarina has.
 * Aww, Look! They Really Do Love Each Other: Despite Katarina being clueless about love and affection to the point that she has never kissed a boy on the lips, he does have feelings towards Rentaro. She even tells Imperia that she likes Rentaro for being headstrong. Heck, she even may get embarassed around him, which of course was a chance for Atala to mock her.

"B" Tropes

 * The Baby of the Bunch: Of the original core group, Katarina is the youngest and least mature. She's babied to the extent that Imperia worries about her the most. She's still the strongest and most competent of the bunch in terms of fighting... Of course, until she gets serious... People start to learn her true colors of a cold mature amazon.
 * Backup from Otherworld: When she was killed by Isaac Westcott when tried to rescue Tohka Yatogami from DEM Empire. Due to her high energy, Katarina did not went neither Limbo, Hell, Paradise nor Valhala--Due to her Abyssal and ExKrieg energy, her soul made a hole in the Spirit Worm Hole of the Omniverse, making her soul to fall on the depths of the unknown regions of the omniverse. This caused her to fall on the world of Minecraftia, the Kingdom of the Cosmic. Of course, after many rape attempts of lustful mob princess, she escaped and returned to the Living World... However, she may be too late as the final battle was about to start.
 * Badass Adorable: Throughout her childhood. Even after growing into an adult, she remains an endearingly innocent and kind-hearted woman in the body of a grandfmother by the end of it. She is naive and cute at times with her cheerful personality.
 * Badass Baritone: In her ExKrieg transformation, her voice becomes noticeably deeper and serious.
 * Badass Boast:
 * "I see. But before I lose control of my personality, let me tell you something. I mastered many styles of martial arts but I should not use them against you. Because each martial art is a respectable product of human technique. Techniques that should not be used through the anger. Therefore, I must send myself to my anger and use pure violence as an animal rather than a human!"
 * "Chaos claims the unwary or the incomplete. A true man may flinch away from its embrace, if he is stalwart, and he girds his soul with the armour of contempt."
 * "Never let your sense of morals prevent you from doing what is right."
 * "You already know don’t you? I am your loved daughter that you tried to kill when I was just a newborn baby. I came from a planet called Earth in order to defeat you all from Balam Alliance. I'm here to bring you despair, fear and panic! I'm here to bring you nightmares! With my fist that carry all lives you took from, I'll send to you to a place worse than hell, the NOTHING! Prepare to die! Because you're not my father!!"
 * Badass in Distress: For the most of Mafusa Gang's Revenge sub arc, Katarina was the Princess in Distress while acting as the main antagonist. Due to Vira's ability in infecting Katarina with the Blackness, Katarina impaled Azul and the guilty feeling made her be consumed by her evil-alter ego, Elesis Du Tirial. Thus, turning her in a Princess inside of a psychological cage where Elesis was the bad girl.
 * Badass Normal: Even before discovering her super human strength, she was already able to defeat dozens of Mafusa Gangsters using only martial arts and combat skills.
 * Badass Teacher: Demonstrates her competence at teaching after she takes her job more seriously in LOTM: Destiny. She also demonstrates that she's a very capable combatant even 5 billion years later.
 * Balloon Belly: Occasionally after eating a big meal such as when she ate a massive dinner bought by Kotori at the end of Mafusa Gang's Revenge Sub Arc.
 * Batman Can Breathe in Space: Though it was claimed way back during Saga AA that her race couldn't breathe in space, in LOTM: A Draw of Kings, she fights Isaac in the vacuum of the Multi-Universe's space in a beatiful and epic battle between father and daughter.
 * Bearer of Bad News: Is the one to inform everyone that Tomas became a Black Demon through Ara's machinations.
 * Be Careful What You Wish For: She wanted to fight strong guys... Always... And she got it but in the worst way... A BUNCH of them. Megalomaniacs, ruthless dictators, destroyers of planets, eaters of universes, overpowered Gods and many more.
 * Being Good Sucks: While Katarina is usually the paragon for Good Feels Good, she does have a moment like this after Vira is defeated. She really, really, wants to leave Vira to die after she's cut to pieces, but Katarina's morality won't allow her to ignore a call for help, even from an evil monster like Vira who did terrible things to her. She eventually gives in to his conscience and gives Vira enough energy to heal and run away... In exchange she will never show her face again before her eyes. Of course, as always, the cruel being will act like a jerk.
 * Berserk Button: It didn't happen often, but when she was a child calling Katarina coward, weak, idiot or stupid caused her to lose her cool. This is seen when La Folia called her a sad person for being alone all the time when they met for the first time in their entire lives... It resulted in Katarina trying to stab the young La Folia.
 * Berserker Rage: Has gone into dozens of times, mostly during a fight where the bad guy manages to kill someone close to her, breaking her promise of protecting them.
 * Beware the Nice Ones: Katarina is a very easy-going and kind person who tries to be polite and friendly to everyone, but you do not want to piss her off. If you see her face stained in darkness, you're dead. Darth Hades found that out the hard way for exposing his crimes to all survivors ExKriegs who managed to escape from the ExKrieg Genocide.
 * Beware the Silly Ones: Because of how naive and childish she was she had no problem playing hide-and-seek with her enemies, choosing to eat over fight, or just act like a goofball in the middle of a battle. Despite this, she still kicked her opponent's butts and not let's get started on what happens when she is serious.
 * Big Ego, Hidden Depths: Katarina is loud and boastful because she needs someone, anyone, to notice her as a person and not a monster with blood-like hair.
 * Big Damn Heroes: Is an absolute pro at this. Whenever things look like they’re at its most grim, Katarina will usually appear out of nowhere and save the day (or least give the heroes a fighting chance). She saves the Rogues seconds before Heis would have crushed their bodies and she stops Terumi from killing Kyouko. It happens so many times that it got to the point that Katarina's friend lampshades this tendency of her... At one point Atala even joked about this saying she waits behind a rock and when things seems to get bad, she will appear in front of her enemies out of nowhere.
 * - Atala: Where have you been, anyway?
 * - Katarina: Sorry, I am late.
 * - Atala: Don't play the hero, we all know you waited for this to happen to make an epic entrance!
 * - Katarina: Hmm... Maybe.
 * - All: MAYBE?!
 * - Ellen: What an annoying woman!
 * The Big Girl: When she's not in a leadership or main character role, she becomes this since she is one of the most powerful beings in the universe and is considered the 'heavy hitter' alongside Alliance of Freedom's male members among her group of friends.
 * Big Sister Instinct: Will do anything to protect Imperia. She tried to do the same with other Rogues members but failed many times.
 * Bizarre Alien Biology: Katarina is an ExKrieg who are Human Aliens who are insanely aggressive and love to fight, have red hair, red eyes, can transform into Berserkers and can transform into Red Haired Demons that changes their hair and eye colors while also greatly increasing their strength and speed. If they are pushed close to death and recover, they increase their strength. Despite this, they can interbreed with humans, creating even more powerful hybrids. In Katarina's case specifically, he has an enhance sense of smell, hearing, and sight.
 * Blasphemous Boast: When you have several Gods who seek death, misery and despair, it's most obvious you will expect Katarina saying something about defeating or killing those Gods.
 * Blood Knight: The extremely rare unambiguously heroic version. She lives for the thrill of the fight and is always looking for stronger opponents to battle for fun or merely because she wants to become stronger. Even when she's on the brink of death, she's always having fun, and seemingly insurmountable odds only EXCITE HER MORE. She also only fights opponents who are willing (most of the villains), and only kills as a last resort. This was also her primary motive in sparing Oriax's life. She also expresses a wish (later granted by Supreme God) to see Eckidina reincarnated as a good girl just so he can fight him again, which resulted in Echidna StinWalker being born after Eckidina became an Abyssal. She went so far as to put a hit on herself so Voldemort, the legendary assassin of DEM, will come to use her full power to fight her. Hell, this girl's such a Blood Knight that she projects this quality onto her half-human first born daughter, Rinslet Couteau.
 * Blue and Orange Morality: As an ExKrieg, it's in her blood to love fighting and combat, which has caused her to make poor decisions in the past. Sparing Aki Honda's life after their battle so she can fight her again as a worthy enemy and Petelgeuse to live are two of them. In Hell Saga, when Katarina's morality is questioned because of her love of fighting, Imperia calls Katarina kind-hearted but questions her righteousness. At the same time, she doesn't go looking for these kinds of situations, and is content to live a quiet life in the countryside, albeit one involving a lot of physical training. She seems to be aware that these situations find her, though.
 * Boisterous Bruiser: She loves to fight more than anything, is somewhat rude without meaning to, is not the brightest person in the world because she lacks a formal education, and amazingly grows up with a fine and hottie woman's built. She is also one of the most fun-loving, friendly, and happiest people in the story. As a child, she was even more this trope since she had no problem beating up people weaker than her with a huge grin on her face.
 * Boobs of Steel: Physically strongest female character in the series and while she don't have the biggest chest  (as she has around C cup) of the story, she can still beat even Gods and Devils like candy.
 * Book Dumb: She grew up without a formal education, aside from learning basic reading and math while. Before that she thought 14, not 12, came after 11, and afterwards it's revealed during her first fight with Aki Honda, 5 years prior the beginning of the story, that she still can't count past 25. Even as an adult, he still comes off as an idiot. As an adult, though she still can be naive and a little too willing to trust others, what keeps her from being an Idiot Heroine is that she can show surprising wisdom, and it's clear that her intelligence is focused on combat. When it comes to fighting and battle strategy (military and gaming included), she's a genius, able to point to pick up on the strengths and the flaws of various techniques, outthink her opponents with good strategies, and she can learn and invent new techniques with relative ease.
 * Breaking the Fourth Wall: In MAD Volumes, she do that a LOT!
 * Break Them by Talking: Her battle against Leohart after she becomes a Legendary ExKrieg is half Roaring Rampage of Revenge and half this, surprisingly enough. She trash-talks Leohart during the whole battle, mocking her strength, appearance, intelligence, dreams and even his ideologies all the time, something that is definitely not usual for her at all. And the final blow which she intended to end the battle with is a deliberate, armor-piercing "The Reason You Suck" Speech to utterly obliterate Leohart's pride. Even when compared to all the physical punishment she receives during the fight, for Leohart that speech is probably the absolute worst part of the Humiliation Conga. And that's EXACTLY what Katarina is going for, since she understands that destroying Leohart's ego is a more fitting punishment than just killing him.
 * Brilliant, but Lazy: Katarina's IQ is above 300! In real life, this IQ is extremely high and is equal to the brains of 5 scientists together. Katarina is intelligent and can be very well be a genius but if it doesn't relate to fighting or getting stronger, Katarina has no interest in it. However, when comes to military battle plans, Katarina outmatch every single character of the story.
 * Broken Ace: The stronger she becomes the more heartbreak she is forced to deal with. Her badass boasts gain credibility the more she matures and she also grows beautiful to the point that Ara calls her her mature body of a "slut" and a weapons grade badass with various boys and girls in her new homeplanet taking a liking to her after she became a sloppy teacher at an University years after the end of the Cataclysmatic War. However, he also suffers massive guilt over not being able to save Imperia, hides deep insecurities behind a goofy attitude and smile and endures numerous Break the Cutie ordeals one which includes God sacrificing himself so he could seal Unit-CM 130 in another dimension.
 * Broken Hero: Between her past, Eugen, Vira and La Folia's death.
 * Brooding Boy, Gentle Girl: Inverted. As she is the brooding to Rentaro's gentle.
 * Brought Down to Badass: For the interim between the Genocide Arc of LOTM: A Draw of Kings and the next arc, Katarina is afflicted with Latent Energy Disorder as a result of using the Abyssal and ExKrieg energy at their 100% with Legendary ExKrieg, severely bottlenecking her power.
 * Bruiser with a Soft Center: One of her defining characteristic. Her friends often comment on how she can be so powerful, yet also so gentle. This also sticks out since she is an unapologetic Blood Knight.
 * Bully Hunter: A prime example. One of the types of people Katarina dislikes the most are those who intentionally abuse their power. She also despise the ExKriegs for being Space Pirates who commit genocide and wants nothing to do with her own race. Although Katarina doesn't grow stronger necessarily to protect others, she does believe that being powerful gives you certain responsibilities, like not terrorizing those weaker than you. This idea became so powerful that she started to hunt gangsters and criminals over Tenguu City at night, gaining the title of Red Haired Demon.
 * Butt-Monkey: The Fraxinus crew punishes her whenever she messes up her training. Punishments involve broadcasting embarrassing moments from her past, penalty games, and the like.
 * But Now I Must Go: When Aki Honda and Mafusa Gang invades Tenguu City, she immediately set off and gave a farewell to Mana and La Folia, thinking she might not return as she was going to settle her business with Aki Honda once for all.

"C" Tropes

 * Cain and Abel: THREE examples.
 * The Abel to Elesis' Cain, her evil-alter ego living inside of her mind who can also be considered her sister as they are two personalities who inherited two differents bloodlines. Katarina holds the power of the ExKrieg's biological while Elesis holds the power of the Abyssal's biological power.
 * The Abel to Vira's Cain, her adoptive sister who was once known as Eugen Katsuragi. Formerly, Eugen was a Cain character just like Katarina but her corruption by the Blackness turned her into a vicious psychopath with tendecies to genocide, spree-killing and even incest rape relationships.
 * The Abel to Alisa's Cain. While Katarina is the daughter of Mikaela and Isaac Westcott, Alisa is the daughter of Isaac with an unnamed sex slave he raped. The sex slave is never shown in the story but Isaac made sure to Alida grow up like a vicious and wicked murder.
 * Came Back Strong: As a racial trait of being an ExKrieg, Katarina can become stronger from coming back from near death... When she returned from Minecraftia, she returned 100% stronger as she was Killed For Real!
 * Can't Catch Up: In LOTM: A Draw of Kings especially, she shows frustration on how her friends depends on her to save the day because they simply can't keep up with the ever growing power of new threats coming from DEM Empire after she returned from Minecraftia.
 * Captain Obvious: Though it's more about her being a smartass towards the situation.
 * Casting a Shadow: She can manipulate shadows/darkness in some of her skills.
 * Category Traitor: Yuuchiro outright declares her a traitor to the ExKrieg race for refusing to join him in his quest to kill Isaac Westcott and take revenge for their race.
 * Cavalier Competitor: She is this unless it's clear her opponent's evil is greater than their desire for a good fight.
 * Celibate Hero: Towards Tomas Sev, while she likes him as a friend, his love towards her makes her ignore him whenever he is acting like a playboy trying to win over her.
 * Cerebus Retcon: Katarina was eventually revealed to be part of a race of alien warriors who conquer planets after torturing, killing and even raping its population. The only reason she didn't wipe out humanity was because she suffered an injury in her head and because she learned love from her parents.
 * Challenge Seeker: Katarina loves to be challenged when she fights someone, rather they are friend or foe. Unlike other Blood Knights in the story, she wants to battle people who have a reasonable chance of defeating her since winning isn't her primary goal, but self-improvement.
 * Character Development: The Season 1 and Season 2 showed the most great example of the story with all characters, such as La Folia, who once was kind-hearted girl but became a sadistic queen. But Katarina was way more bigger.
 * In season 1, Katarina had no qualms about hurting for enemies like a beast. As time progressed and she got older, she starts to mellow out more and becomes more composed instead of acting like a creature searching for her next prey. There's also the fact that Katarina, as a child, had no concept of the morality of taking lives. She barely understood life and death to the point of being an amoral being, this of course caused her to suffering bullying from society. There are some times he killed purposely though, such as killing aMafusa Gangster after beating a student, not that gangster didn't deserve it. Another part of her no kill policy comes in later when many of her worst enemies became her loyal friends, realizing that if they could change, anyone could. When she does finally use lethal force against villains like Aki Honda and Aryana Westcott it's because she realizes that they're beyond redemption and rotten to the core. And even if she's made up his mind that her opponent needs to be killed, Katarina will show some degree of mercy to the villains if they are not ruthless bastards like Aki Honda, Ara Astaroth, Unit-CM 130 and among other monsters she faced before, while displaying regret that they weren't good people, because she'd rather have them as rivals and sparring partners.
 * She also gets Older and Wiser as the series progresses. As mentioned above, she's still very much a Blood Knight but she mellows out considerably and tries to avoid taking a life if she can, and uses a lot more strategy in combat and training, to the point that she masters it to an art form and many of her allies consider her a genius when it comes to fighting. She also gains a better understanding of the world and people around her, while still being goofy and kind of naive.
 * Character Tics: Like her father, she tends to cross her arms when flattered.
 * Character Title: The title of Sword of Kings refers to the Sword of Kings sealed inside of her. This sword is so well hidden in her soul that not even Elesis was able to detect it.
 * Cheerful Child: As a child, she is a relentlessly happy person despite most of the stuff that happens to her like the death of her parents at an early age and living alone in the mountains for a number of years. However, over time, her happiness finally faded and she became an emotionless delinquent.
 * Childhood Brain Damage: It's stated that the reason why Katarina doesn't share the violent nature of ExKrieg is that she received a blow to the head while she was a baby. This blow caused her mind to be split in too, thus creating Katarina Couteau. Yes, before this blow, the person in control of the body was Elesis but this impact caused a new personality known as Katarina to be the main host of the body while Elesis was kept sleeping inside of her mind until her power started to flow.
 * Childhood Friend Romance: With Rentaro, the boy who has admired, acknowledged, and loved her for the way she is since the day they met. Rentaro was a bullying and above all, arrogant... But when Katarina beat him up, he started to feel bad for the things he has done. Years later, it was him who was suffering bullying when Katarina, this time, rescued him instead of punching him like years ago. Of course, she started to grow feelings for him too but she had no knowledge of love to understand what she was feeling towards him.
 * Childhood Friends: With La Folia who became Imperia.
 * Child Soldiers: Although she wasn't sent to Earth to destroy it like originally believed, it isn't unusual for Frontier Babies to be sent out when they're no more than three.
 * Chick Magnet: When she crossdress like a man, many girls of Ratatoskr implies she is way more "handsome" than most men in Fraxinus. It turns out she accidentally became a famous false "harem king" because of that.
 * The Chosen One: Played With. Yuuchiro firmly believes that one needs to be the Chosen One to become the reincarnation of the Legendary ExKrieg, the warrior that saved the Multi-Universe from the Fallen I and his Abyssal Empire, something that should be achieved by him since he is the son of the ExKrieg King. After being beaten to near death by Darth Hades, he concludes that Katarina is the real Chosen One destined to ascend and defeat the Balam Alliance to save the Multi-Universe once again after trillion years after the original ExKrieg's death. According to the legend, each 500 sixtillion years, an ExKrieg will become the incarnation of the Legendary ExKrieg one the Multi-Universe is facing a dangerous threat. However, it turns out it was nothing like that. The reason why Katarina was able to form a link the original ExKrieg was because of her pure heart that is different from all other corrupt and vicious ExKriegs. Even after her death, there will be another ExKrieg who will become her reincarnated version in the next generation of omniverses.
 * The Chosen Zero: What almost everyone believes her to be until she proves herself.
 * Chronic Hero Syndrome: He cannot bring herself to pass by someone in need, even if they are the worst beings in the universe.
 * Color Motif: Red. Her clothing is largely consistent of red clothing and the color represents her Scarlet hair as well as her ExKrieg's bloodline.
 * Comically Invincible Hero: Early on her absurd invulnerability is Played for Laughs most of the time. Not so much with A Draw of Kings, although does show up at times like the Sith battles.
 * Confusion Fu: Katarina may not be the brightest bulb nor have a style, but her fast mind and unpredictable nature mean that she can land surprising strategies.
 * Contagious Heroism: After being forced into Enemy Mine situations with Katarina; Oriax, Mey, Ellen Mira Mathers, and Chinatsu become more heroic and selfless characters, although it takes Chinatsu a long time to reach this point. She's also able to spread this to Future Maria of all people.
 * Conveniently an Orphan: Kotori finds that she has no family left, which makes dealing with her new status as Ratatoskr's subordinate.
 * Cool Big Sis: She acts as this towards her guildmates in her age range whenever she isn't beating the crap out of them. She is also this one to Eugen Katsuragi and Alisa Ray Peram Westcott.
 * Cooldown Hug: Gives one to Elesis in their meeting at the end of Mafusa Gang's Revenge sub arc to prove she still cares for her Elesis.
 * Cool Teacher: See her Badass Teacher above.
 * Create Your Own Villain: The Rise of Qliphoth's timeline shows that Imperia would have continued to serve the light despite her grudge against life for many years  for sadistic tendecnies. However, Katarina's meeting with Ara triggered the Cyborg's Darkness, eventually leading her to start planning mass genocide of all life for the mere sake of having fun with pain. In other words, if Katarina decided to let the Witch Cult deal with Ara in some way (which would probably fail), Imperia would have never met Ara, who would later seduce her with promises of war and massacres. This meeting caused the evil Future Imperia, Achyls, be born.
 * Not to mention that she indirecly killed Eugen Katsuragi, resulting in her being born as Vira. If Katarina decided to finish off Aki Honda, she would have never killed Eugen in the first place, preveting her from being revived as a Black Demon centuries ahead in the future.
 * Crouching Moron, Hidden Badass: It is very easy to forget, given her laid back and childish demeanor, that she is one of the strongest beings in the universe and is currently one of the strongest mortal fighter in omniverse.
 * Cruel Mercy: It really depends on your point of view but when Sonia Nevermind was cut limb by limb by the ruthless Yuuki Terumi, Katarina would probably suggested to send Sonia to a Heal Tank inside of Fraxinus to restore her body as she was cursed with Terumi's immortality, preventing her from dying no matter in how many pieces her body is cut. Instead of letting her live, she thought it was better to get rid of her physical body by exploding it release her soul from the suffering. But like said above, it's all a matter of view.
 * Cosmic Plaything: Considering how nonchalantly Isaac Westcott, her father is a Multi-Universal nazi dictator, her deceased sister Eugen was revived as an lustful Black Demon known as Vira, La Folia murdered by a narcissist queen, her mother was killed by Ara,, her biological mother sliced by Isaac, growing being treated like a monster by society and Akrak being a sociopathic scientist, it's rather surprising that she still has some sort of self-worth (or perhaps it is because of all this).
 * Curb-Stomp Cushion: When she first goes Legendary ExKrieg against Diabla; though Diabla manages to land several good blows and puts up a decent fight, she burns through her stamina too quickly to be a serious threat to Katarina for long.
 * Cursed with Awesome: Having the Elesis sealed and the brutal ExKrieg tendecies within her makes nearly everyone in the town hate her, but the trade off is access to Elesis' energy in addition to rapidly developing her personal energy reserves to the point where she has more raw power than most Magicians, Magi-Tech users, Cyborgs, Gods, Demons, Angels and Spirit before the story even begins.
 * Cute Clumsy Girl: She's a bit clumsy and insecure, and also full of thoughts on her head.
 * Cute Monster Girl: Come on, admit it — Katarina is adorable no matter how ugly she can get in her Berserk form! Oh wait...

"D" Tropes

 * Dark and Troubled Past: For all of her childhood,  Katarina was hated by nearly the entire town (save for a very few number of people who were always nice to her) for reasons that she didn't know of so she kept smilling and being cheerful like all children. But one day when her parents died, that happiness vanished, leaving only an empty sad child.
 * Dark Is Not Evil: Her colors are often related to red and black, starting with her hair color and black energy. While most villains have the same dark too, Katarina,  however, is sweet-natured and sunny. Even when she's become a full-fledged Abyssal, she remains as kindly as ever.
 * Deadpan Snarker: Occasionally. It's usually to show that she's not as dumb as people think. SHe particularly loves to snark Azul when she's being particularly annoying.
 * Death Glare: If Katarinais shooting one of these at anyone, someone is about to get their heads cut off. Literally.
 * Deceased Parents Are the Best: She has nothing but fond, happy memories of her parents. In her childhood, she often quotes her father's lessons or copy his cooking techniques.
 * Deconstructed Character Archetype: From the Madness Sub Arc onwards, Katarina becomes one for The Ace and the Hope Bringer. Because she is so good and so powerful her friends and allies tend to depend on her too much to solve the current problem and they don't put their trust readily in anyone else but her to finish off their enemies. They become noticeably deflated and pessimistic when she, Atala, Tomas and Imperia aren't around, and Azul firmly believes that she can never surpass her, despite Katarina showing her otherwise. Katarina being sent to the fufure of Rise of Qliphoth era is one of the many reasons why things got so bad and in the present. Katarina herself has realized that her loved ones are far too dependent on her; she knows that one day, she will be dead for good, and if her loved ones don't stop relying on her, Imperia, Tomas and among other equal to her powerl level, so much, then no one will be able to counter the next big threat to Earth or even the Multi-Universe.
 * Declaration of Protection: She vowed to protect every single member of Ratatoskr and the Rogues. Her declaration turned out to be her Goal in Life.
 * Defeating the Undefeatable: Something of an inversion, Aryana Westcott was shilled as being an incredibly strong one woman army (literally) that beat the Pure-Blooded Devils in a fight. The woman tanked Katarina's strongest attack and was only defeated when Katarina recreated the way she got her scar; by having her run herself through with her own technique. Not to mention that Aryana is far one of the strongest characters of the story.
 * Defeat Means Friendship: Most of Katrina's friends started out as anti-heroes or villains who wanted to kill her. After Katarina meets them in battle and defeats them, they eventually become her friends.
 * Defeat Means Respect: Rarely, if she is defeated by a worthy opponent like Azul, she will immediately show respect and honor towards the person.
 * Deliberately Cute Child: According to Kotori the entire ExKrieg race is this trope. ExKrieg have long childhoods to stay cute and young to throw off their enemies, thinking they're harmless, before quickly growing into their adult size.
 * Determinator: Going up against impossible odds is all part of the fun for this girl. She will keep fighting even with broken bones, torn muscles, and holes in her body. Yet, fighting is not the only thing she do in this trope. Katarina does not give up ever. She doesn't go back on his word or any promise she made with a close one. She travalled universes, realities and dimensions only to rescue Tohka and would travel through infinite years of trips between omniverse to fullfil the dreams of someone.
 * Designated Villain: Invoked in order to help Andr and Cupa unite the Kingdom of the Cosmic, making her the villainess who caused chaos and war in Minecraftia. Of course, Played For Laughs.
 * Despair Event Horizon: The reason why Katarina considers Aki Honda to be her personal enemy is for a good reason. This is downplayed with a immense Tear Jerker. When Aki Honda impales the innocent Eugen right in front of her when she was trying to carry the injured Katarina away from Aki Honda. The sensation of feeling her sister dying in her arms was a shock so big that it caused her sanity to break.
 * Deus Exit Machina: After becoming a teacher in an University 5 billion years later, Katarina becomes increasingly entrenched in her bureaucratic and duties. As such, she is rarely able to go out of her way deal with threats unless they come directly to her town. Naturally, this prevents her from turning every fight into an effortless Curb-Stomp Battle due to how ridiculously powerful she is compared to everyone in the main cast in LOTM: Destiny.
 * Didn't See That Coming: Many of them but the most impressive was she did not see Rentaro being in love with a girl like her.
 * Did You Just Flip Off Cthulhu?: She evidently doesn't give a damn over whether not Vira knows about love and how she can control her. Katarina kills her anyway.
 * Did You Just Punch Out Cthulhu?: In the climax of Order of Terror Arc, she manages to drag Madness out of the LN-666 Project Spirit (which give her godly powers) and then strike her down to her very soul. Madness is actually impressed at this and she Died Laughing.
 * Ditzy Genius: She's an absolutely brilliant fighter, but has No Social Skills whatsoever.
 * Don't Make Me Destroy You: In Saga AA finale, this is Katarina's almost word-for-word warning to Michael Langdon after the end of the final battle between the heroes and Diabla. It was one of the few moments that Maria truly feared Katarina.
 * Do Not Call Me "Paul": She (initially) didn't like anyone calling her by her birth name, Elesis, since she feels intense shame for belonging to a race of genocidal pirates, and vehemently refuses to identify herself as an ExKrieg until she comes to feel pride for her heritage as a warrior.
 * Doom Magnet: To prevent new Dark Empires from attacking the New Republic because of her presence, she chooses to simply remain hidden for the safety of the Multi-Universe since so many of the villains they have fought so far were mostly after her in the first place. Which is ironic since we learn much later that Balam Alliance's remaining empire stood away from the Multi-Universe because they were terrified of her.
 * The Dragon: To Astaroth King during Madness Sub Arc, a villainous example while she was under the possession of Elesis.
 * The Dreaded: By many! Be they heroes or villains.
 * The reason why Mafusa Gang named her Red Haired Demon was for a good reason. They fear her so much that several groups of criminals refused to go out at night, thinking she might appear in the darkness of some alley to bite off their limbs.
 * As shown in a filler episode, a Sith is terrified of Katarina to the extent that he beats it the minute he discovers Imperia is her sister.
 * She becomes this to the entire DEM empire to the point that one of Westcott's men outright tells the Longinus Order to leave the ExKrieg alone and go back to running their empire.
 * Drill Sergeant Nasty: She can be really tough on her guildmates.
 * Dude, Where's My Respect?: Katrinais seen as the Hope Bringer among her family and friends. Outside that circle, however, no one knows or cares about her. This is mostly because Katarina purposely keeps herself under the radar, preferring to live a peaceful and calm life when fighting is not involved. However, Katarina has helped a number of people and she was actually known as the person who beat Eckidina and the Fallen's Essence, saving the world. For the lack of words, Katarina saved trillions and trillions of lives but no one seems to know her, so they simple treat them like a normal person walking in public in the streets. Yet, Katarina never deemed respect or knowledge of every single in the universe, only her friends and family.
 * Dueling Messiahs: Exemplified in her fight with Ara. Katarina aims for peace. Ara also did, but by destroying every single piece of atom in the existence itself to create an infinite void of emptiness.

"E" Tropes

 * 11th-Hour Superpower: It seems to happen several times when she is facing a dangerous threat, Katarina will be forced to activate her Abyssal power to fight the final boss instead of relying in her ExKrieg energy.
 * Elemental Powers: Katarina's natural elemental ExKrieg and Abyssal energy affinity is Darkness and Fire.
 * The Empath: Katarina gains the ability to sense negative emotions while using the Elesis' power when she defeats it. Which is why she was able to detect Tomas' Blackness inside of him.
 * Empowered Badass Normal: When we are first introduced to Goku, she had super human strength, speed, and durability. Some of this is because he's an ExKrieg who are naturally stronger than humans, but most of it came from her years of training and living in the wilderness.
 * Enemy Within: Shares this with Elesis. Due to a head injury when she was a baby, Elesis was cast aside and slept inside of Katarina's head for years. When she wakes up, she was played an antagonist who tried to ruin her life many times to take over her body again and again. However, the two ended getting along.
 * Et Tu, Brute?: Basically her reaction when first saw Vira, who is very similar to Eugen Katsuragi, her deceased sister who was killed by Aki Honda.
 * Even the Girls Want Her: She has quite the following of female admirers in addition to her male ones. She is even goes into Attractive Bent-Gender territory while playing a prince in Minecraftia, making the women in the audience comment on how handsome she is in both Ratatoskr and Minecraftia. In addittion, she even crossdress as Butler in the festival of Raizen School before Aki Honda decided to ruin the party.
 * Everyone Has Standards: Katarina is always looking for a good fight, regardless of the age or gender of her opponent. That doesn't mean she enjoys senseless murder and slaughter. She likes the chance to test her skills; to see which is the strongest.
 * Evil Counterpart: Katarina has a lot of these, often overlapping with Not So Different and Shadow Archetype. The most notable examples are Elesis, Alisa and Aki Honda.
 * Evil Is Not a Toy: In the beginning of Season 2, Katarina continued to rely on Elesis' energy as a result of desperately wanting to save the Rogues and her friends from Heis and other future threats like the Zero Numbers. She ended up almost killing Azul and Imperia had to have a sit down talk with her about which power she really should rely on; the ExKrieg or Abyssal energy.
 * Evil Twin: Elesis looks identical to Katarina in appearance, shares Katarina's love for combat, being challenged, are the strongest in their respective races, and they both have a technique similar techniques.
 * Exactly What It Says on the Tin: The Abyssal energy of Elesis. It can supposedly slay ExKriegs and Abyssals. Not that we doubt it, seeing what Katarina can do. Oddly, she is the daughter of an Abyssal.
 * TheExtremistWasRight
 * Expecting Someone Taller: In Unit-CM 130 sub arc, she's genuinely surprised to discover that Maria, the famous Angel of Flame is now no longer a amazon Cyborg like she was before her death. She is even more surprised to see that she is now more sophisticated and more composed than before, more like a Ojoo-Sama.
 * Experienced Protagonist: By the time of A Draw of Kings, she's become a seasoned warrioress.
 * Explain, Explain... Oh, Crap!: When she asks Imperia where did she come from, Imperia starts explaining till she has a sudden revelation that La Folia is an artificial human created by the Fallen's Essence and Lusamine.
 * Expy: She is based off in many shounen anime characters. See her page.
 * The Extremist Was Right: Sephiria Arks KnightWalker always belived peace can be achieved through love but after learning more Katarina and the enemies they faced together, she immediately noticed some people cannot feel love so murder is necessary at times. Katarina taught it to her.

"F" Tropes

 * Face of a Thug: Despite looking perpetually emotionless when as a pre-teen, she is actually a pretty good girl when you show her some kindness.
 * Family of Choice: Having grown up without parents, she sees the Rogues as her true family.
 * Family Theme Naming: A variant. Katarina shares a syllable with her father Iruka, her mother Haruko.
 * Fastest Thing Alive: Took this title from the Multi-Univese itself after gaining control over Westcott's Abyssal energy.
 * Fearless Fool: She fits this to a tee at first glance, as she pretty much leaps into danger with a smile, ready to punch or (as necessary) headbutt her enemies without fear of her own safety. However, Katarina is much more complex than that. In the beginning, the lack of fear was indeed out of recklessness, but after the encounter with Kanon Rihavein, it came out of a desire to prove herself and protect her loved ones.
 * The Fettered: Despite her protests, Katarina has a pretty solid moral compass and draws strength from her refusal to give up and her desire to protect what's close to her. She says every time she is ready to do anything to accomplish her goals, including murder and torture... But when the time comes, she often shows her Sweet Side and gives up in trying to do something vile to save someone.
 * Fiery Redhead: She can get angered easily, especially by her guildmates' antics. She was actually quite timid as a child.
 * Fight Magnet: Being the main character the story, there are a lot of people wanting to kill her.
 * Fights Like a Normal: Mostly shown in story, where she mostly fought hand-to-hand or sword-to-sword; whenever she used the energy techniques, she usually did so as an ace in the hole or a Desperation Attack.
 * The Final Temptation: Westcott offers her this after killing Alisa, and Katarina nearly takes it until Maria slaps it out of her.
 * Fire-Forged Friends: Done with most of Katarina's friends, most noticeably with Azul, Oriax, Ellen, Alisa and Evelynn Astaroth, all who tried to kill her at one point. Through trial and hardship, they all eventually become True Companions.
 * First Love: Rentaro. Katarina fell in love only twice in her life, who turned out to be Rentaro, whom only came out of her mind 500 million years later. And later, Myouri, a young student who fell in love with her, it turns out Katarina was his teacher. Despite that, Katarina's love for Rentaro was way more important and vital to the story more than any relationship as it was her love for him who unleashed her Abyssal power during Diabla's battle. This love was so strong that it took her million years to finally forget these feelings.
 * Flight: Comes with the powers of ExKriegs.
 * Fluffy Tamer: She manages to befriend all of the Gods of Evil like Thanatos, Ah Puch, Nox and even Hades the God of the Underworld after Leohart's death, the self-proclaimed "living incarnation of hatred".
 * Foreshadowing: One of her dislikes is ghosts. And the Fallen's Essence is one; he's possibly even the reason for this phobia in the first place.
 * Flying Brick: Her ExKrieg Mode gives him: durability, speed, ability to throw numerous Pillars of Agony without limit, and as mentioned above flight.
 * Foil: One underestimated yet important aspect of Katarina's narrative is that if you put her next to a major character that runs up against her, chances are there will be notable parallels between them blanketed by critical differences that set them apart and establish why Katarina is the purer of all around her.
 * Forced to Watch: Forced to watch Westcot killing Imperia with a stick and even forced to watch him brutally killing Azul in front of her in the hopes her dark side will explode.
 * Forgiven, but Not Forgotten: This is Katarina's attitude towards Oriax after all the harm that she's caused. After hearing of all the hardship Oriax went through which led her to being the person she was, Katarina realizes that even if she can't stop herself from hating her for what she's done, she will still forgive her.
 * Forgot About His Powers: Several times she's not used techniques that would have been really helpful with the situation at hand, for no apparent reason.
 * Forgotten First Meeting: Sh met Maria when she was a Cyborg during LOTM: Witnesses of Sleepy Hollow & Sword of Kings Crossover - The Corbin Files. Months later, Maria eventually remembers her, Katarina... doesn't. Of course, this is explained by Maria's different look and outfit.
 * For Happiness: The reason why she fights is because she wants to see all of her friends happy.
 * For Want of a Nail: If La Folia hadn't spoken in her defense against society, Katarina would have walked the same path Oriax and Ara did, a fact she repeatedly dwells on. Worse, she could grow up as serial killer and would allow Elesis to take over her body, destroying mankind in the process.
 * Freak Out!: Happens thrice.
 * When she witness Eugen being impaled by Aki Honda and could only feel her sister dying in her arms as Aki Honda had cut her eyes off. The physical and psychological pain made her go insane for a while and allowed Elesis to take over her body.
 * When she watched Kanon killing La Folia right in front of her in a cross on the middle of an arena. Kanon even mocked Katarina while destroying La Folia's locks to make her body fall from the cross. Seeing her childhood friend who acted like a sister for a long time made her insane again.
 * Third was his worst one ever, when she was Forced to Watch Westcott killing Azul, the man who killed her mother, Elliot and was directly responsable for World War III in her homeplanet and killed Tohka, almost fatally stab Imperia with a giant spike. The Freak Out was of such proportions that it allowed her to instantly go to her to Full Abyssal for the first time ever, then an Abyssal monstrosity, and then left her will so badly battered that she was ready to release the let Elesis take over her body... Of course, because of her friendship with Katarina she refused.
 * Friend to All Children: By the time of LOTM: Destiny, Katarina shows a great fondness towards younger kids, considering them as the future generation of defenders.
 * Friend to All Living Things: Even as an adult she loves playing with animals like a big kid, and regards them as friends as if they are also human.
 * Friendly Rivalry: After having very heated rivalries with almost all of her friends, their relationships eventually evolves into this. Azul is the most standout example since it takes Azul's entire character arc before she finally settle her beef with Katarina always being better than her. The hair colors, Katarina being red, and Azul being blue is to show their opposite side of the same coin.

"G" Tropes

 * Gender Bender: Her male version as the Prince of Kawari Skeletons in Minecraftia is considered to be one of the most handsome males of In-Universe.
 * Generation Xerox: ExKrieg, the original and Legendary ExKrieg has more on one occasion remarked that Katarina resembles and is surely able to surpass himself (in terms of awesome and stupid). Yes, even the Legendary ExKrieg admits he was naive and almost idiot like Katarina at times.
 * Genius Bruiser: Downplayed, since she has never had any formal education and often lacks common sense. However, she is an excellent combatant and a tactical genius, able to pick up new skills and techniques with ease. Furthermore, once she gets a basic understanding of something, she learns very quickly, even math problems.
 * Genius Ditz: She may normally be an idiot, but the plans and strategies she comes up at the span of seconds while under pressure are definitely to be admired. It has gotten to the point it is Lampshaded at various points in Season 2 of Saga AA.
 * The Gift: She is a strong, natural, brilliant fighter despite being born a low class warrior among her race. Yuuchiro outright says that she has a gift, something he refused to even acknowledge for a long time. Tomas himself notes that Katarina is a prodigy upon seeing that she kept using her Abyssal energy and managed to defeat Elesis many times. Given how weak Katarina was compared to the other villains at the start of the stories, her strength come from natural talent enhance by a lot of hard work.
 * Glowing Eyes of Doom: Whenever she is pissed, her face becomes shadowed while her eyes glow red.
 * Goal in Life: To protect Prime Earth and protect every single one of her friends. Later, her goals in protecting Earth accidentally throws her in a battle for the sake of the existence itself.
 * Good Cannot Comprehend Evil: Katarina frequently underestimates just how evil some people can be, and is all too willing to give them a Last-Second Chance when she has them at her mercy.
 * Good Eyes, Evil Eyes: The widen open eyes of happy-go-lucky Katarina vs. sharp and red of serious in-a-fight Katarina.
 * Good Feels Good: A defining characteristic, and a main reason why Katarina is such a Nice Girl. She does almost all her good deeds because she enjoys being a good person and really can't understand why anyone likes being a scumbag.
 * Good Is Not Dumb: Zigzagged. Katarina is the Book Dumb Idiot Hero, but it's been implied time and time again that the reason behind her seemingly idiotic nature is that she grew up without anyone properly teaching her anything outside of the school.
 * Good Is Not Soft: Any villain who crosses the line or pisses her off will feel her wrath, in the bad way. There will be times where not even herself will be able to control her murderous intent.
 * Gonk: Played For Laughs. Her wanted poster of the New World Order and DEM Empire.
 * Got the Call on Speed Dial: After the end of the Cataclysmatic War, she decided to live like a normal person again in a planet distant from the New Republic to prevent more people from attacking it while the Republic was in stage of formation. When the New Balam Alliance was founded, she returned to her duties in protecting innocent lives, abandoning her status as teacher. However, she was only protecting her galaxy.
 * Graceful Loser: On the rare occasions she meets an enemy she truly can't beat, she admits it without any ego involvedç. By contrast, most of her enemies are such Sore Losers that they would rather blow up the planet they're standing on than accept defeat, like Aryana Westcott and Heis.
 * Grand Theft Me: Is the victim of this three times by the same person, Elesis. The first time by Elesis when she witnessed Eugen dying, the second when Katarina's Berserk form ended and allowed Elesis to take over her body in Aldegyr Kingdom and the third when Katarina plunged herself in darkness after impaling Azul, thus allowing Elesis to take over again.
 * The Greatest Story Never Told: Almost all of Katarina's adventures and world saving isn't known by the general public. Only a few people know that she's the one who killed Aki Honda (like the Chronos Empire soldiers who rescued her from the building where she fought Aki Honda). Only the Rogues know she is the one who saved the world from being destroyed by the Black Army of the Rogues. Only a dozen of people know she was the person who defeat the Unit-CM 130. No one knows who destroyed the New World Order, who stopped the Sith's Darkness Plan, the entire mess with Aryana happened on another planet and she was killed before she could terrorize the Prime Earth. In addittion, no one knows she was the one who saved the Multi-Universe three times from Balam Alliance by defeating Darth Hades who tried to destroy all light, Leohart who tried to corrupt the Core of the Multi-Universe to turn the entire omniverse in a Living Hell of heat and Isaac Westcott who tried to literally destroy the Multi-Universe, and Sephiria Arks KnightWalker takes the credit for destroying Longinus Order and the Revelation of Qliphoth, and for defeating Sequined Sadist. The reason behind all of this is because Katarina hates attention and fame so she will always put the credits in another person to avoid people seeing her like some kind of new Jesus Christ. When Saga AA ends, she even put Kyoko Kirigiri as the salvior of the world for destroying Diabla when in truth she was the one who defeated her.
 * Greater-Scope Paragon: In LOTM: Destiny. After she disappeared with the ending of LOTM: A Draw of Kings, Katarina became a unseen character for the most part of the story yet she was the reason why the story continued existing. Not to mention she is the true founder of the New Republic, the main heroic faction of the story that serves as the superior group of the Wolf Pack Squad. In addittion, she is catalyst character for the story itself as she was person who literally created the plot of the story by defeating the old Balam Alliance.
 * Grin of Audacity: Katarina is prone to give these when she's prepared to face a strong opponent, something her friends lampshade at least once.
 * Guile Hero: In Eckidina Arc, Katarina comes up with a number of surprisingly good schemes for a supposed Idiot.
 * Guttural Growler: Often gains a growly voice when using the Elesis' energy.

"H" Tropes

 * Happily Adopted: By Couteau family, more precisely, Haruko and Iruka Couteau. Though unfortunately, they are killed by the machinations of Ara Astaroth for adopting a child, breaking their Satanic Pact.
 * Hard Head: She once took an axe blade to the head; the axe shattered on contact.
 * Hard Work Hardly Works: Played with. While Katarina is indeed a talented prodigy, she was born at the absolute bottom of the ExKrieg pecking order and had to constantly train to get where she is now. On the other hand, she learned how to perform the Pillar of Agony, which took the Fallen's Essence, the creator of the technique, 50 years to master.
 * Has a Type: Hilariously, female ExKriegs naturally go for feisty, strong-willed men. However, much to Kotori's surprise, she has a crush in Rentaro, who is the total polar opposite of the typical violent and brute men that female ExKriegs likes, shy and calm.

Imperia Deamonne
Imperia Deamonne (born as La Folia Rihavein and as La Folia KnightWalker in an alternative universe) is the secondary heroine in LOTM: Sword of Kings storyline and its sequel, LOTM: A Draw of Kings. She is also a recurring character in some parts of LOTM: Witnesses of Sleepy Hollow and is one of the secondary heroines of LOTM: Witnesses of Sleepy Hollow & Sword of Kings Crossover - The Corbin Files.

La Folia had a past filled with false memories and sad incidents. She believed herself to be a princess of Aldegyr Kingdom. For most of people, including herself, she is the eldest daughter of King Lucas and Polifonia Rihavein, and the elder twin sister of Kanon Rihavein. She was pursued by Magnus Craft and the Aurozia Terrorists Organization to hold her as hostage in order to acquire all the money from her Real family. However, in truth, she was merely a clone of the original Princess La Folia Rihavein made by The Fallen's Essence (an abyssal shadow made by the orginal Isaac Ray Peram Westcott) and Lusamine in order to test the effects of Human Purifier Techonology, with her entire life being manipulated by the former.

Under a pretense of the real La Folia, the clone La Folia was sent back to her parents (alongside a clone version of her original versions' twin sister, Kanon Rihavein) while her original version suffered from all kinds of assault, abuse and even tortures which eventually killed her slowly and painfully. The Fallen's Essence was closely observing the life of La Folia and manipulated her, making her a puppet to his will. Under the manipulation of the Fallen's Essence as well as the Order of Terror, La Folia suffered from the abuse from her father (possessed and driven to insanity by the Fallen's Essence) and eventually left her kingdom to quit her life as a princess. She ultimately ended up in Tenguu City, Japan, and was followed by the forces of the KnightWalker Family secretly manipulated by the Fallen's Essence, again, in an attempt to assassinate her.

During those years, the Fallen's Essence had more plans on this clone made by him, but when La Folia met with an orphaned Katarina Couteau and befriended her, the Fallen's Essence had to made a new plan on her. During her time at Tenguu City, she becomes Katarina Couteau's best friend in her childhood. She knows she is a very rich princess, but like Katarina, she had a tragic past and hates being princess since she was exiled from the world. She never talked about her past to Katarina and the latter never asked as well.

La Folia was both kind and pure, and she cared about her best friend and gave Katarina a glimmer of dawn upon her dark childhood. However, during her time in Tenguu City and the beginning of the World War III, La Folia suffered attacks several times from the hands of many villains, most notably Eckidina KnightWalker, Misogi Kumagawa, Michael Langdon and Moloch. Even so, La Folia did not lose her sanity until after her capture by her sister, under the order of the Fallen's Essence. When Lusamine and the Fallen's Essence revealed her true past in front of her, La Folia finally realized that all her past life was a total lie before sucubbed to the execution committed by her "sister", Kanon Rihavein, who became the zealous servant of the Fallen's Essence. However, during the battle full of chaos in Aldegyr Kingdom, La Folia was revived by Chinatsu as a Cyborg with superpowers whears her personality remained unspoiled. Now named as Imperia Deamonne, La Folia joined the Rogues and became allied with Ratatoskr in order to fight against the Fallen's Essence, the true mastermind of the entire events and prevent the New World Order from raising. Both she and Katarina were happy about this revival.

After the destruction of both the Fallen's Essence and Diabla the Qliphoth Tyrant, Imperia was among those heroes and villains who were teleported to another universe by the Reality Council to fight against Balam Alliance. During this time, Imperia was almost corrupted by Darth Hades and Leohart the Prince of Hell, but she all went through it. However, this was changed horribly during the Cataclysmatic War, when the original Fallen, who was the Emperor of Deus.Ex.Machina Industries Empire, had drove her into despair and insanity before turning her into his Abyssal so that she would destroy the Alliance of Freedom from inside. Under Westcott's mind-control, Imperia slaughtered many of her friends and battled against Katarina, which ended up with her own tragic death and the destruction of the Alliance of Freedom, driving Katarina into despair.

With her own death, Imperia's soul was freed from the Fallen's control and redeemed herself, but the loss and consequences it brought was tremendous. However, eventually Katarina regained her hope and fought against her father with her ultimate Prime Abyssal Punisher power and destroyed him before he could destroy the entire Multi-Universe with his final form, avenging Imperia's corruption and death.

She is an original character created by DestroyerSubjugator90 and Prime ShockWaveTX from CIS Productions.
