The Clowns are a motorcycle gang that appear in the pilot episode of Scary Godmother. These hoodlums are tougher than they look. When the Clowns attack Jimmy and his crew, one of the Clowns smash Hannah's head in with a pipe. Hannah, left for dead by the others, would not have survived if it weren't for Scary Godmother's healing spells.
The Clowns make their second appearance in episode 3 when Hannah interrupts one of their gang bangs with her new nen abilities. The Clowns are thrown about and retreat.
In episode 19, Jimmy, wanting to test out his new Disaster Blaster weapon, destroys what's left of the motorcycle gang.
