The Simpsons have met many villains and donned many a heroic guise over the years, and now this brand-new series of bi-annual specials will tell more of their exciting tales! Witness the cream-filled fury of Pieman (a.k.a. Homer Simpson) when an evil doppelganger seeks to tarnish his indignant and indulgent identity! Then, follow Bartman and Houseboy (Bart and Milhouse) into a parallel world when they find themselves in the bizarrely-altered world of Shelbyville. Add to the mix a trilogy of Radioactive Man tales (including a new origin story!) inspired by the storytelling of Steve Ditko, and you have gotten one spectacular super Simpsons special.
