Captain Tooth is a bat from the Nameless Zone.
History
Along with Sergeant Claw, Tooth was searching for live subjects for the Arena of Doom. Whilst hiding behind a rock, he overheard Witless Chris tell Scratchy about how he always battles six bears before breakfast. The pair snatched Witless into the air, but Tooth was soon thumped in the side by Tails. Completely astounded at the sight of a flying fox, Tooth fled.
