Fiora is one of the main protagonists from Xenoblade Chronicles and a childhood friend of Shulk's.
Xenoblade Chronicles[]
Fiora is the little sister to Dunban, a war hero that fought against ruthless machines known as the Mechon. Fiora was there when her brother returned home from the Battle of Sword Valley. For an entire year, she cared for her injured brother who was still recovering from the war.
Fiora takes good care of the people in her life as she is an excellent cook, with the men in her life enjoying the food she makes very much.
A year after the Battle of Sword Valley, she and her best friends, Shulk and Reyn, were going about their day like always when they witnessed a terrible ambush of Mechons in their peaceful settlement of Colony 9. Shulk and Reyn did the best that they could to fight off the threat, but even the Monado, which was very well known for being a match against the Mechon, had very little affect against the ruthless machines.
When the boys were struggling to fight off the machines, Fiora came in and fought them on a massive machine from the colony's army. Despite Shulk warning her to flee for her life, she continued fighting on until she was brutally slain by the machines, which prompted Shulk and Reyn's journey.
Even though Fiora was killed, her body was used as a vessel for the entity, Meyneth, who was placed in a Mechon that was specially piloted by Holmes.
Shulk and his friends did not see Fiora again until they arrived on Prison Island, where they found out that not only were there Mechons being piloted by Holmes, but the one that was piloting a white, feminine looking Mechon called the Nemesis, was Fiora, who was possessed by Meyneth.
Inside her own body, Fiora fought hard, screaming for Shulk, but her screams remained unheard for a time. However, her pleading managed to affect Meyneth in a way, in whish she somehow developed feelings for Shulk, so she left on her own to find and speak with him. However, Metal Face found out who she was and followed him.
When she relocated Shulk and his friends, she didn't seem to remember any of them but before she had a chance to talk to them, Metal Face appeared, revealing to have been piloted by Mumkhar, Dunban's former friend who was presumed to be dead a year prior. He used Fiona to threaten Shulk into giving him what he wanted, the Monado. It worked, but not for very long. After the confrontation, Mumkhar returned to the Mechonis with Fiona.
Ultimate Story[]
Fiora made her debut in Ultimate Story 7. She didn't have a majorly vital role to play in the Ultimate Endgame but partake in the Ultimate fight. Much like in Xenoblade Chronicles, Fiora is very protective of Shulk, almost to the point where she would tend to be aggressive towards anyone who would threaten his safety.
She, like Shulk, resides within the Xenos Sector of the Vesperia Galaxy.
