Depiction In Equestria Girls[]
Rainbow Rocks[]
In the film, Adagio and the other Dazzlings are introduced in the human world. They are sirens from Equestria who were banished to the human world by Star Swirl the Bearded to prevent them from using their dark magic to conquer Equestria. They are first seen in a café causing tension between the patrons when they witness the Equestrian magic that brought Sunset Shimmer to her downfall in the first film. Some time later, the reformed Sunset gives a tour of the school to Adagio and the other Dazzlings and tries to be friendly, but she gets suspicious when Sonata randomly blurts out that they sing to get people to do what they want and Adagio gets defensive over her pendant. Soon after, they convince all of the students except the Rainbooms and Sunset with their music to turn the nice, good and friendly Musical Showcase into an aggressive, violent, mean and angry Battle of the Bands.

BOO!!! BOO!!! BOO!!! BOO!!!
Adagio and the Dazzlings use their siren's songs to control student opinion and advance through the competition bracket. When the only bands between them and first place are the Rainbooms and Trixie and the Illusions, Adagio manipulates Trixie into removing the Rainbooms from the competition permanently. In the final battle against the Rainbooms, Adagio and the Dazzlings are eventually defeated, and the gem pendants with which they controlled the students are destroyed. As a result, the trio's terrible singing has resulted in being chased off in disgrace.
Trivia[]
In music terms, the word Adagio is a tempo marking indicating that music is to be played slowly.
