The Toxic Crusaders is a G rated cartoon series based on Lloyd Kaufmans R rated The Toxic Avenger films created by Troma movies.
The show's original title was Toxic Avengers, but this title was seen as too violent, so it was changed to Toxic Crusaders.
Both the creators of this show and the Teenage Mutant Ninja Turtles were friends. There was talks in the works to crossover the two shows, but unfortunately nothing ever became of it.
