Based on Lloyd Kaufman’s cult 1984 comedy film, The Toxic Avenger The Musical tells the story of the citizens of Tromaville who are crying out for a hero. Enter nerdy Melvin Ferd the Third, an aspiring earth scientist, determined to clean up the state’s major toxic waste problem. When a corrupt Mayor and her government goons get wind of his plans, they vow to stop this heroic feat. Melvin is attacked and tossed into a vat of toxic waste... transforming him instantly into The Toxic Avenger, New Jersey’s first superhero! Toxie is a 7-foot mutant freak with superhuman strength and a supersized heart to match. His aims are to save heavily polluted New Jersey, end global warming, win the heart of the prettiest (blindest) librarian in town - and get home in time for dinner!
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.
Toxie finds he has nothing to do as a superhero, as he has ridden his city of evil. So he decides to go to work for a major corporation, which he discovers may be the evilest of all his adversaries.
The Toxic Avenger has a major midlife crisis and must travel to a mythical land called the "Heart of Fartness," deep in the Panamanian jungle, in order to regain his place as the first Super-Human-Hero from New Jersey.
