In the quiet, corrupt town of Tromaville, a catastrophe strikes the Tromaville School for the Very Special when a rogue terrorist cell known as the Diaper Dads holds the students and faculty hostage. Enter Melvin Ferd Junko III, better known as the heroic, grotesque mutant Toxic Avenger, and his fiercely loyal, blind sidekick, Lardass. Toxie rushes to the rescue, engaging in a brutal and chaotic battle to save the innocent children. However, during the explosive showdown, a massive thermal-nuclear blast detonates. The catastrophic event tears open a rift in the space-time continuum, sending Toxie into an alternate, twisted reality known as Amortville, where everything is inverted and evil reigns supreme.In Amortville, honesty is a crime, cruelty is celebrated, and Toxie’s reflection is an evil, sadistic counterpart named the Noxious Offender. Meanwhile, back in Tromaville, the original Toxie is
presumed dead. The well-meaning but dim-witted Melvin is accidentally switched with his evil parallel self due to the dimensional warp. While the Noxious Offender wreaks havoc in Tromaville—terrorizing citizens and spreading malicious destruction—the real Toxie finds himself trapped in Amortville, fighting for survival against hostile, perverted locals and trying to figure out a way back home.Back in Tromaville, Toxie’s pregnant wife, Claire, goes into labor amidst the chaos. Claire struggles to protect her unborn child from the malevolent Noxious Offender, who poses as her husband to deceive her. As the town falls deeper into despair, a ragtag group of survivors, including Tromaville’s eccentric mayor and various mutants, try to expose the imposter and survive the onslaught of violence.In Amortville, Toxie teams up with bizarre local resistance fighters, including a disgraced superhero and a giant cat named Attorney General. Utilizing sheer determination and his signature radioactive strength, Toxie battles his way through Amortville's corrupted government and treacherous wasteland to reach the dimensional portal. He manages to leap back into Tromaville just in time to confront his evil double.A colossal, blood-soaked final showdown ensues between Toxie and the Noxious Offender. Toxie ultimately overpowers his wicked doppelgänger, banishing him and restoring order to both dimensions. Claire safely gives birth to their child—a mutant infant with multiple heads and
extraordinary powers. Though Tromaville remains as delightfully bizarre and filthy as ever, Toxie emerges victorious, reuniting with his family and reaffirming his status as Tromaville’s ultimate, deformed defender of justice.
