Radioactive Man: The Movie
Dr. Clownius is a villain who has an army of clowns. When some of his clowns found Silly Sailor, they brought him to meet Dr. Clownius. Dr. Clownius had Silly Sailor kidnap Gloria Grand so he could pull off his plan, going in disguise on WZEN News as Dr. Swartzwelder so he could make Radioactive Man look bad. However, Radioactive Man and Fallout Boy stopped Silly Sailor and stopped the broadcast at WZEN News, revealing Dr. Swartzwelder to be Dr. Clownius.
In the unfinished Radioactive Woman film, Bart had Krusty play the role of Dr. Clownius. Due to a gas that turned all of his henchmen violent, Dr. Clownius got beaten up.
