Captain Amazing, protector of Champion City, is kidnapped by his archenemy, the insane super villain Casanova Frankenstein. The city's fate now rests in the hands of seven superhero wannabes: the fork-flinging Blue Rajah, the shovel-wielding Shoveler, the possessed bowling ball-hurling Bowler, the flatulent Spleen, the only-when-nobody's-looking Invisible Boy, the mysterious Sphinx, and the perpetually angry Mr. Furious.
