It has a pointed muzzle, red lining around its eyes and mouth, teal eyes, a fluffy black ruff of fur around its neck, and a long, voluminous crimson red spiky mane with gray tips. A teal-colored band encircles the bottom part of Zoroark's mane like a ponytail. It has three sharp red claws on both its hands and feet.
Zoroark is able to stand upright on two legs like a biped, but it usually runs upon its forelimbs.

This is similar to Ninetales, another Pokémon based on the Kitsune. Zoroark also resembles a Werewolf, a mythological beast that was human but could shape-shift into a wolf or an anthropomorphic wolf-like beast.
Zoroark's name comes from zorro, which is Spanish for "fox", and "dark".
