Sonata Dusk

"Favorite element: darkness! Favorite magic: dark magic! Favorite word: that 'agathokakological' thing! Favorite instrument: xylophone! Oh, and my name's Sonata. Sonata Dusk."

Sonata Dusk 'is a female pegasus and one of the main antagonists of My Little Pony Equestria Girls: Rainbow Rocks''. She is a backup singer in her band the Dazzlings, rivaling the Rainbooms.'''

Depiction in Equestria Girls: Rainbow Rocks
Throughout the film, Sonata Dusk is shown to be rather ditzy and easily distracted, similar to Pinkie Pie. For example, before they sing their song in the cafeteria, Sonata is more focused on getting lunch since it is Taco Tuesday. Also, she and Pinkie are the only ones who actually seem to enjoy Snips and Snails' rap performance.

Depiction in the Goldieverse
Sonata's Goldieverse counterpart does not differ much from her MLPEG:RR counterpart, although she is slightly less evil here and there. Unlike her MLPEG:RR counterpart, her true form is not a siren, but a pegasus. Her siren form is just a mere projection from her amulet.
