Zazz is a very tall and very lanky Zeti, with very thin limbs and body structure. The upper half of his body appears to be vibrant pink, while his body from the waist down is pure black, ending in two-clawed feet with purple toes. A third much smaller claw appears to jut out from his heels. Zazz has a long tail that appears to be bent into a vague "Z" shape. Zazz has a row of small black spikes running down his back, from the base of his neck to the middle of his spine. Zazz's thin arms end in proportionately large five-fingered hands, each finger tipped with purple nails.
Zazz has an oblong head with a large gaping mouth, which is never closed. He has long, thin, sharp teeth and a long cyan tongue, which is almost always seen hanging out the side of his mouth. He has green irises with yellow sclera and black markings under each eye. On the top of his head, Zazz has a pair of horns that point outwards, colored in alternating rings of black and light purple. Between them is a mohawk of purple hair.
Zazz wears a pair of black wrist cuffs with gray spikes on them, and a matching spiked collar.
