Zomom's entire body is somewhat circular in shape, giving him a rather chubby appearance. His upper body is a vibrant orange-yellow color. His thick arms end with equally large five-fingered hands with yellow nails. His lower body is pure black, and Zomom's legs are so stubby to be nearly non-existent. His flat feet are each tipped with a pair of yellow claws, with a third on the heel. Zomom appears to have some sort of stubby tail.
Zomom has thick yellow lips and he appears to be missing some teeth and others seem chipped. Unlike the other Zeti however, Zomom's teeth are square in shape instead of sharp fangs. Zomom has small red eyes with yellow sclera, with black markings surrounding each eye. As seen in the cutscenes, both of Zomom's eyes rarely point in the same direction. Zomom is fully bald, unlike the other Zeti. On the top of his head Zomom appears to have four relatively short yet sharp horns, each one being striped black and red. On his wrists Zomom wears a pair of black bracelets with gray spikes.
