Mr. McMahon is a tall, muscular otter with blue hair and a blue flame tattoo on his chest similar to a tuxedo design, along with a black nose, peach muzzle, and two teeth sticking out on his lower lip.

He is the leader of The Hang 5 and very eccentric, though wise most of the time and can be serious when he does important things. He’s a congenial fellow and always good mannered.
