Og

Og was a bounty hunter who appeared in "Episode VIII: Jack versus Mad Jack." He was referred to by Jack as "crazy round man."

Description
Og speaks in a shrill voice, and is short, round and furry, with long, sharp claws and a belt, presumably holding ammunition. It is worth noting that he fights Jack with his claws instead of other weapons. Jack defeats him by ducking and using his legs to propel him out of the enclosed area around the bar where he fought him. His name is revealed in the credits. He is voiced by Tom Kenny.

Trivia

 * Og somewhat resembles Chewbacca from the Star Wars franchise.
