Cupcake Kid

Cupcake Kid is the superhero alias used by Bart Simpson, and is a sidekick to masked vigilante Pie Man, who is in fact Homer, throwing pies at Springfield's miscreants. When Mr. Burns finds out Homer's alias, he asks him to pie his enemies instead. But when one of them turns out to be the Dalai Lama, Homer decides to unmask himself. Cupcake Kid and Pie Man have been released as a figure set by McFarlane Toys.
