Residing in Kronosaur, the Cave Man would capture humans from all times and feed them to Big Steggy, his pet. Once Max was teleported inside, Cave Man attempted to club him over the head and feed him to Big Steggy. However, Max tripped the Cave Man, who fell into Big Steggy's mouth. Big Steggy promptly ate and killed him.
- Cave Man should not be confused with Gor the Caveman.
