Jankey

Jankey is Dr. Muto's hunchbacked assistant and the tritagonist of Dr. Muto.

History
Jankey is Dr. Muto's loyal servant. Invented by Muto himself, Jankey is an ape-like simpleton wearing a propellor beanie, a labcoat sewed together out of scraps, and a single wheel instead of feet. Jankey informs Dr. Muto of Midway's destruction; after the intro to the game, Jankey is never seen again.
