After ridding Tromaville of evil, Melvin Junko, the Toxic Avenger, has nothing left to fight. Evil has been vanquished, his mop is clean, and his heart feels… empty. Depressed and emotionally adrift, a psychiatrist with questionable motives encourages him to reconnect with his long-lost father in Japan. But this heartfelt journey is merely a charade, as Apocalypse Inc. lures Toxie overseas in order to blast him with Anti-Tromatons, corrupting his superhuman senses.
Blinded to the forces of evil, Toxie returns home and becomes a corporate puppet for infernal forces bent on enslaving Tromaville… and the world! Can the Toxic Avenger reclaim his soul and save Tromaville once again, or is the hero of the people doomed to become the very monster he always feared?
The Toxic Avenger Part II and The Toxic Avenger Part III were originally written and shot as one movie, but directors Lloyd Kaufman and Michael Herz ended up with so much footage that they broke it up into two installments. 36 years later, the filmmakers' initial vision for the sequel has been reconstructed under its original title, Mr. Melvin.
