Citizen Toxie: The Toxic Avenger IV

Lore & Background

The plot follows the Diaper Mafia, criminals dressed as infants, who commit a mass shooting at the Tromaville School for the Very Special. The Toxic Avenger (Toxie) intervenes, kills the gang members, and later impregnates his wife Sarah. An explosion transports Toxie and two students to Amortville, a mirror universe. Meanwhile, the evil Noxious Offender (Noxie) appears in Tromaville and begins murdering citizens. Toxie encounters alternate versions of characters, including a scientist named Chester (the alternate Lardass) and Evil Kabukiman. Noxie becomes mayor of Tromaville and impregnates Sarah. Toxie eventually returns to Tromaville by clicking red shoes and saying 'There's no place like Tromaville.' He fights Noxie while their babies fight inside Sarah's uterus, ultimately killing Noxie. Sarah gives birth to twins—one fathered by Toxie, one by Sgt. Kabukiman.
