Zarude is a simian Pokémon resembling a baboon or mandrill. Its body is primarily covered in coarse black fur, though its chest and belly are patterned with shorter gray fur. Its upper snout, palms, and rings around its eyes are devoid of fur, and its skin is a light gray. The fur around the side of its head angles into wing-like crests on either side of its eyes. The eyes themselves have red sclerae, green irises, and black, slitted pupils. Its teeth are pointed and its canines are visible when its mouth is closed.
Zarude are social and live in packs. They're usually incredibly aggressive, and frighten most other Pokémon; excelling in battle with their sharp claws and quick wit. However, Zarude occasionally exhibit a softer side. A caped Zarude named 'Dada' split from its pack to raise and nurture an orphaned human infant. It's said that this Zarude derived unique strength from its bond to the adopted human child.
