Megablast is excited to be participating in the Greenville Talent Show and are working on a song for it. But the Copycats want to be the winners and lock Megablast up to keep them from performing. Then, when the Copycats realize they don't know who else is performing, they lock all of the citizens in town in their homes just to be sure they won't have any competition. Beatrix and Aunt Jenny help Megablast bust out. Megablast transforms into Rocket, Thunder and Metallix and must free the trapped townies and thwart the shape-shifting trio before their talent for mayhem takes over!
