Citizen Toxie: The Toxic Avenger IV

Toxie races home to find a way to stop Tex's bomb, leaving Lardass to handle the remaining threat. While Lardass successfully neutralizes the explosive with peanut butter and dispels it through flatulence, a Diaper Mafia member accidentally ignites remaining explosives with a cigarette lighter, killing Lardass. This tragic choice highlights the chaos of the moment and the film’s darkly comedic approach to heroism.

Earlier, Lardass proves his worth by吞下 peanut butter bomb, setting up his heroic yet fatal role.

Amortville is an alternate dimension that mirrors Tromaville but with a much more violent police force that shoots first and asks questions later. After the school explosion, Toxie and his companions find themselves transported there, though the mechanism of this dimensional shift remains ambiguous. The film uses this parallel world to explore darker versions of familiar characters and situations.

Noxie is Toxie's evil doppelgänger wreaking havoc in Tromaville while Toxie is trapped in Amortville. Created as a dark mirror of the hero, Noxie partners with Nazi Sergeant Kazinski and becomes involved with Claire, Pompey's estranged wife. Noxie serves as the primary antagonist, representing everything Toxie could become if he succumbed to corruption.

The film establishes early on that alternate realities contain twisted versions of its characters.

Toxie and Chester attempt to return by emulating Dorothy from The Toxic Avenger, clicking their red shoes together and chanting 'There's no place like Tromaville.' While thisWizard of Oz parody doesn't work literally, it appears to catalyze their return, though the film keeps the mechanics deliberately vague and absurd.

Sarah reveals she's pregnant with twins from different fathers. One child belongs to Toxie, while the other belongs to Sgt. Kabukiman, who wandered into Toxie's home in a confused state. This bizarre paternity revelation creates tension in the finale, with Toxie battling both the villain and the complicated news of his partner's pregnancy.

Chester is Amortville's version of Lardass, a once-brilliant scientist now reduced to begging on the streets. Toxie promises to help Chester reunite with his estranged wife Claire. However, Toxie later discovers Claire is now Noxie's lover, which triggers a violent confrontation with Evil Kabukiman. This complicated love triangle adds emotional stakes to the dimension-hopping narrative.

Toxie mentions reuniting Chester with Claire early in Amortville, setting up the later betrayal.

Toxie returns to Tromaville just as Sarah goes into labor, forcing him to fight Noxie while she gives birth. The delivery room becomes the ultimate stage for good versus evil, with the birth of Toxie's children coinciding with the defeat of his doppelgänger. The infants even contribute to Noxie's downfall, making it a thematically resonant climax about new life overcoming corruption.

Pompey is a man in Amortville who was horrifically dragged by a truck, leaving him as a disembodied head. He accompanies Toxie throughout the alternate reality and helps search for answers. His grotesque condition exemplifies the film's extreme body horror comedy and his presence adds a surreal element to the journey.

After Tex reveals he has a bomb inside his body, Lardass is left to handle the threat. He smothers the explosive device with peanut butter, which somehow neutralizes it. The bomb is then harmlessly dispelled through Lardass's incredibly pungent flatulence, a quintessential example of the film's absurd, gross-out comedy.

Lardass's signature gassy ability has been established as his unique weapon throughout the series.

In the climactic delivery room showdown, Toxie battles Noxie as Sarah gives birth. The fight reaches its peak when Toxie's newborn twins contribute to Noxie's destruction, details that are as grotesque as they are absurd, perfectly fitting the film's tone. Noxie is vanquished, allowing the birth to proceed under celebratory circumstances.

Evil Kabukiman is the antagonist counterpart to the heroic Sgt. Kabukiman. He provides Toxie with an escape plan from Amortville's police pursuit but later becomes violent when learning about Chester and Claire's relationship. He serves as a chaotic neutral force whose motivations shift throughout the film.

Mayor Goldberg introduces several new superheroes to Tromaville, including a beleaguered Sgt. Kabukiman, as part of the city's increasingly chaotic superhero landscape. This satirical move comments on the proliferation of vigilantes and the government's response to villainy, though most of these heroes meet grim fates against Noxie and Kazinski.
