Biography
The Monkey Man is a human who was enslaved as a child by Aku's robot minions, but left that life when led away by a tribe of blue-skinned, white-haired apes. As per the customs of their tribe, he learned to "jump good", allowing him to leap great and unnatural distances.

He comes across Jack eating, and steals his food. After apologising, he offers to show Jack his tribe. Following the invasion by the rival tribe, he strikes a deal with Jack, who fought off the invaders, to show him how to jump good in return for defence training. Jack shows the tribe various methods of practical defence, ranging from traps to personal combat training. In return, the tribe teaches Jack to jump good via the application of heavy weights and costant training.
