When a great city is threatened by a wide assortment of supervillians, they shoot up the fireworks to summon the Mighty Heroes. This sextet of stumble bum heroes go out to confront the menace at hand, and with a great deal of difficulty, usually carry the day.
The series aired as a Saturday morning cartoon, with a Mighty Heroes story told in two parts, and a classic Mighty Mouse cartoon shown in between.
This series was created by Ralph Bakshi at a pitch session where Terrytoons offered their show concepts to the CBS executives.
At the time this series was developed, Ralph Bakshi had an infant son who got mad whenever Daddy had to go to work. He would throw his bottle at Bakshi as he was heading for the door. This is what gave Bakshi the inspiration for "Diaper Man, the hero who fights villains with his mighty bottle".
