The Cave Master is an optional boss in Wario Land II. He is a member of the Black Sugar Gang. His appearance is that of a large, warthog-like creature and as his name suggests, he is found inside a cave.
In Wario Land II, Cave Master attacks by charging at Wario, who must avoid the attack and ram him in the back, pushing him into the small pit on either side of the small arena. After being knocked off three times, the beast is vanquished. However, if Wario is pushed into the pit, he must backtrack and start the entire fight over again.
