Toxic Crusaders (1991)

Toxie is a grotesque mutant endowed with superhuman powers, but is still a good-hearted and law-abiding citizen of the fictional town of Tromaville, New Jersey; the setting of most of Troma Entertainment's films. In a change from the films, the toxic waste mutated his mop into a sentient being that sometimes battles enemies by itself or gives him ideas on how to solve problems. The villains include Czar Zosta, Dr. Killemoff, and Psycho, polluters from the planet Smogula who wreak ecological havoc with help from Tromaville's corrupt mayor, Grody. Bonehead, a street punk who bullied Melvin, joins them in the first episode.

Dr. Killemoff and Czar Zosta are cockroach-like extraterrestrials from the planet Smogula, a world where pollution is natural as fresh air and water is to Earth. Natives of Smogula thrive on pollution and need it to survive. For unexplained reasons, Czar Zosta and other Smogulans are able to withstand Earth's atmosphere without problems, while Dr. Killemoff wears a breathing apparatus to survive. Dr. Killemoff, like most villains, has a seemingly endless army of foot soldiers called Radiation Rangers.

Other villains and heroes appeared, with most being one-off characters.
