Zoroark is a foxlike Pokemon covered mainly in dark grayish fur. 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.
Zoroark are mysterious and sometimes mischievous Pokémon, although they are generally more serious than their pre-evolution Zorua. They are very protective of their homes and their family. They will use illusions to trick enemies and prevent them from entering their lair.
Zoroark can create incredibly realistic illusions. They can transform into both people and other Pokémon. They use their illusory powers to protect their lair and their pack. They have the ability to fool a large group of people simultaneously with their illusion-generating powers.

Zoroark is likely based on the Kitsune of Japanese folklore, a shape-shifting, mythical fox that would trick unsuspecting travelers for fun. 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".
