Adagio Dazzle

Adagio Dazzle is a female character who is to be the main antagonist in the upcoming film My Little Pony Equestria Girls: Rainbow Rocks. She is lead singer in her band The Dazzlings, rivaling the Rainbooms. Her cutie mark varies across depictions, but always includes at least one gem.

Development and design
In late January 2014, Meghan McCarthy was asked regarding DJ Pon-3 "Is Vinyl Scratch's canon name really Adagio Dazzle?" and answered "Nope." In early April 2014, Michael Vogel stated that "Adagio is AWESOME."

Like those of her bandmates Sonata Dusk and Aria Blaze, Adagio Dazzle's wings are translucent and non-feathered. Human Adagio Dazzle resembles Unnamed Girl #11. Adagio Dazzle's initials match those of a headed character in a film scene worked on by Ishi Rudell on April 10, 2014.

Depiction(s)
The Dazzlings, including Adagio Dazzle, Sonata Dusk, and Aria Blaze, are to appear in My Little Pony Equestria Girls: Rainbow Rocks;   Adagio Dazzle is shown on the cover of its novelization My Little Pony: Equestria Girls: Rainbow Rocks: The Mane Event.

In the film, Adagio and the rest of the Dazzlings are introduced in the human world. Adagio and the other two were banished from Equestria to the human world. They are 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. Later, Sunset gives a tour of the school to Adagio and the other Dazzlings, but tells the main five that something seemed "off" about them. What is "off" about them is confirmed when they convince all of the students except the main 5 and Sunset with their music to turn the friendly Mane Event into an all-out Battle of the Bands.

A singing Adagio Dazzle doll is listed in a Hasbro press release and has been displayed, with packaging additionally showing her pony version, both at the 2014 American International Toy Fair and on Hasbro and Kmart's online listings of the product.
