My Little Pony: Equestria Girls - Rainbow Rocks

Twilight Sparkle (Tara Strong) and her friends compete in the Canterlot High "Mane Event" talent show, but their efforts are thwarted by rival Adagio Dazzle and her band The Dazzlings, who use their magical powers to turn students against each other. The girls, including former school bully Sunset Shimmer, form a rock band called "the Rainbooms" and use their music to counter the Dazzlings' spell and save the school. With the help of Twilight and her friends, the Rainbooms ultimately defeat the Dazzlings and restore harmony to Canterlot High.
