The Dazzlings

The Dazzlings are a musicall group from My Little Pony Equestria Girls: Rainbow Rocks, serving as the main villains of the movie.

The group consists of Adagio Dazzle (the leader), Aria Blaze (the harsh tempered member), and Sonata Dusk (the ditzy member).

They are Sirens from Equestria. Years ago, they used their music to cause a great amount of disharmony in Equestria. This catches the attention of Star Swirl the Bearded, who banishes them to the human world in belief that they would do no more harm, unaware that Twilight Sparkle and Sunset Shimmer would end up bringing Equestrian Magic there.

After seeing the appearence of Equestrian Magic when Sunset was defeated at the fall formal, the Dazzlings enlist at Canterlot High School in order to gain the magic there. They caused disharmony at the school, amongst both students and staff, and turned their Musical Showcase into a "Battle of the Bands". They and the Rainbooms make it to the final round. They were defeated when the Rainbooms destroyed their pendants, causing them to run off. It's currently unknown what happened to them after the Battle of the Bands or during the Friendship Games or the Camp Everfree trip.

Fire Rebellion: Season 15
The Dazzlings will return in Season 15 as one of the main villains. They end up having their memories of the events of Seasons 8 and 12 erased to the point of no recovery, no thanks to Catherine Carter, Cloe Carter's birth Mother. They will set their sights on gaining Equestrian Magic like before and to get revenge on the Rainbooms for what happened to them. But with their shattered pendants, they currently have their sights set on something that could remend their pendants and reactivate their powers: the Ninja Steel. They somehow ended up getting their hands on some of Galvanax' Kudabots and Basher Bots.
