Belle Crocker

Belle Crocker was a villain called the Ghostess and the accomplice of Russell/The Ghost. After the failure of Russell's schemes and his disappearance, Belle went on to become a pianist. However, 35 years later, she was contacted by Russell, who had just come out of a cryogenic chamber and sought her help. She agreed for a while, but rebelled and left the team, even giving Nightshade valuable intel on where to find Russell.
