Ghoul was one of the Jokerz who followed the rejuvenated Joker. He was heavily into techno-goth music and has adapted the horror look into his costume. Ghoul was never without his plastic Halloween pumpkin which he kept filled with a number of monster-inspired weapons and tricks. Stewart Winthrop was born into a wealthy family, but ran away to join the Jokerz for kicks. He served as the group's techie, manning the computers and technical equipment. He was usually paired up with Woof before being defeated by Batman and arrested by the police.
- Ghoul was voiced by Michael Rosenbaum.
