Sylvester Sebastopol was a friend of Lucian Crawley.

Sylvester wanted to become a criminal mastermind and coaxed Lucian to join him at Headmaster Mind's school for villains. He initially went by Punch, until the headmaster informed him of Clyde Phillips, causing him to take the name Clown Boy. The group was confronted by Super Friends, with Lucian and Black Alice using their powers to subdue them. Wonder Woman convinced that Sylvester wasn't a good friend, as he forced Lucian into a life of crime. He and Black Alice agreed with her sentiments and turned on their comrades. They then became superheroes, with Lucian attempting to reform Sylvester.[1]
