Initial Era[]
Fat Ninja
In the Initial Era, Fat Ninja first appeared in Sprinkles the Psychotic Moose Volume 1, Number 20 (1992). He and Stealthy Ninja battled Sprinkles and Jack in an alleyway in Quadropolis. Fat Ninja showed his power by throwing Jack aside with one hand to the face, and in his prolonged fight with Sprinkles. Eventually, Sprinkles knocked Fat Ninja out, and Stealthy Ninja, who had disappeared when Jack called him out on his bragged-about time travelling power, never returned.
