The Toxic Avenger (1984)

In Tromaville, Melvin works in a health club with his bucket and mop as a janitor. The sadistic and bullies Bozo and Slug and their girlfriends Julie and Wanda, who love to hit-and-run people in empty streets, play a cruel prank in Melvin and he falls off the window in a barrel of toxic wastes in a truck parked in front of the health club. He turns into the strong monster Toxic Avenger and protects the town from criminals. He saves the blind Sara from a rape and soon they become sweethearts. At the same time that he is worshiped by the residents, the corrupt Mayor Peter Belgoody and his gang want to destroy him.—Claudio Carvalho, Rio de Janeiro, Brazil
