Adagio Dazzle is a former siren who serves as the primary antagonist of the theatrical movie, My Little Pony: Equestria Girls: Rainbow Rocks.
Adagio Dazzle is a siren who was banished from Equestria to the human world by Starswirl the Bearded. In the human world, however, their powers were much weaker and had to be channeled through special pendants, due to a lack of magic. After Equestrian magic arrives in the human world following the events first film, Adagio begins a plan to make everyone in the world adore them. They enroll at Canterlot High, and quickly use their magic to turn the school against each other, even controlling Principal Celestia and Vice Principal Luna. In a Battle of the Bands, they quickly clash with the Human Mane Six, now a band called the Rainbooms, and Sunset Shimmer, who remain unaffected by their music. In the final round, Adagio and her allies are able to summon projections of their true forms, which clash with the magical counterspell of the Rainbooms. With Sunset Shimmer's assistance, Adagio and the sirens are defeated. Their pendants are destroyed in the clash, leaving the sirens unable to sing, rendering them powerless.
Adagio Dazzle and her fellow sirens could magically cause discord amongst others through song, then gain power from them. Her true form is similar to a hippocampus, a horse-like creature with fish features. However, this form was seen only in the form of a magical projection. However, Adagio could use her powers to assume an anthropomorphic form with pony ears, extended ponytails and fin like wings.
