C.C. debuted in episode 3 of Slugterra, The Trade. He was brutalizing Slugslingers who challenged him when the Shane Gang arrived. He overpowered them until Eli borrowed Stinky from Pronto. C.C. rebounded the Slug with his Frostfang, getting Eli at gunpoint. However, this gave Pronto, Trixie, and Kord enough time to surround C.C. He walked away soon afterwards but gave a warning, saying that his associates have "redecorated" their hideout.
He reappears, slightly redesigned, to tag Eli with a Jollyfist so Dr. Blakk could follow Eli to the Lightwell. At the end of the episode he was taken by the Shadow Clan. He reappears in Back to Blakk as one of the goons to break out Dr. Blakk From Stalagmite 17.
- He works for Dr. Blakk but his mecha isn't ghouled.
