He first appeared in the episode, Bedlam in the Big top. He was secretly portrayed by Harry the Hypnotist. He dressed up as the Ghost Clown, He was seeking revenge against the circus because he was sent to prison after he was caught stealing at the circus. In his revenge, he dressed up like a clown and hid in the shadows to terrorize the circus by sabotaging equipment. When Mystery Inc. became involved in the conspiracy, he began turning them into his mindless slaves with his hypnotic golden coin (brainwashing Scooby into walking on a tightrope, Daphne into dressing up like a ballerina and riding a unicycle non-stop, and Shaggy into lion taming). Fortunately, other members of gang snapped them out of their respective trances. After a plan to capture him in a cage backfires, Scooby and Shaggy decide to turn the tables on the clown by making him inadvertently hypnotize himself into acting like a chimp. Afterward, he is unmasked, unhypnotized, and sent back to prison.
