When the notorious Diaper Mafia take hostage the Tromaville School for the Very Special, only the Toxic Avenger and his morbidly obese sidekick Lardass can save Tromaville. However, an explosion results in some unforeseeable consequences, creating a dimensional tear between Tromaville and its dimensional mirror image, Amortville. While the Toxic Avenger (Toxie) is trapped in Amortville, Tromaville comes under the control of Toxie's evil doppelganger, the Noxious Offender (Noxie). Will Toxie return to Tromaville in time to stop Noxie's rampage or is he doomed to remain a second-class citizen in Amortville forever? How did Toxie's wife Sarah become pregnant with two babies from two different fathers? Will Tito ever get over his teen angst and become a productive member of society? Written by Doug Sakmann

Didn't see Parts 2 & 3? Not to worry. They sucked!
29 March 2003 | by (DEEP 13) – See all my reviews

Teenagefsufan obviously doesnt know what Troma Truly is.

This movie proves that Lloyd Kaufman and the rest of the citizens of Tromaville are truly insane. Didn't see Parts 2 & 3? Not to worry. They sucked! So declares a stirring Stan Lee voiceover heralding our hero of super-human size and strength that culminates with the apologetic declaration: "THIS is the REAL sequel!!!" When unsavory members of the Diaper Maffia storm Tromaville's school for the "very special" and begin machine-gunning slow-witted, taco-gorging hostages, Toxie and faithful ward Lardass swoop in to permanently stink-can these dastardly diapers by hyper-gruesome means such as literally cramming a dude's head up his hiney. During the blood-splattered melee, plot rears its hideous mug when a budget defying explosion craters the school creating a dimensional rift that rockets The Toxic Avenger into evil, evil Amortville and his demonic doppelganger, The Noxious Offender, into the peaceful, yet bizarro tranquility of Tromaville. While Toxie struggles to peaceably adjust in an appearance obsessed culture, Noxie immediately yanks off the arms of the police chief and demonstrates a murderous

This outing, the longsuffering hulk beneath four-hours of Avenger latex is one David Mattey who apparently never grasped the trials he'd have to weather in this exercise in guerilla filmmaking. Such as the indignity of having his voice REPLACED after filming in favor of more FM-hewn pipes (Clyde Lewis). Doesn't much matter anyway because Paul Kyrmse steals the flick with his inspired comedic antics as a cowardly, booze-addled Sgt. Kabukiman NYPD. As Chester and Lardass, CineSchlocker idol Joe Fleishaker delivers the tour de farce performances of HIS hefty career. Jiggling newcomer Heidi Sjursen, clearly a method actress, adeptly uses blindness as sufficient motivation to never FIND a bra in her titillating turn as Toxie's baby's mama. Porn icon Ron Jeremy goes braless as well as Tromaville's fundamentalist mayor. Think THAT's ironic? Wait til you see how he croaks. Also keep those peepers peeled for unforgettable cameos by CineSchlocker faves Corey Feldman
