Zazz did not originate from fanon, and the information on this page may not be entirely accurate to their canon. You may read more about this subject in the context of their canon on the following wiki(s):
Zazz is a wild and unruly character with an unpredictable personality that makes him destructive even by the standards of the other five Zeti. He's also quite the hothead that will fly into a rage when he gets held back from fighting. He loves running wild more than having three meals a day and hates boredom above all else. When fused with Zor, they form Zither.
Zazz is a tall and lanky demon-like being in pink, having black legs and crooked horns with violet stripes. His head is oblong and is adorned with a purple mohawk, and his face features mean-looking eyes with yellow sclera, black bags and green irises. His mouth is always wide agape, featuring a set of fangs and a long, cyan tongue.
Zazz's tail is about as crooked as his horns are. He wears two spiked bracelets around his wrists and wears another one around his neck. He has large five-digit hands, with each finger having long, purple nails. His feet have two purple talons for toes and has a third one on his heel.
