Bigwig is the main villain of the arcade video game Hairdo Wars, created by Gus for Blake's Videorama in "Horror of the Haunted Hairpiece", an episode of A Pup Named Scooby-Doo. Crusty Baker impersonated Bigwig in an attempt to close down the arcade because he thought it was making too much noise and driving customers away from his restaurant.
Bigwig is a large humanoid male covered entirely with yellow hair. He has big eyes and sharp teeth.
Bigwig seemingly came right out of the Hairdo Wars arcade game while Scooby-Doo was playing it. Bigwig was eventually captured and revealed to be Crusty Baker.
