Zoroark is a bipedal, slate gray, fox-like Pokémon with crimson and black accents. It has a pointed snout and ears with red insides. It also has some red that rims its eyes and mouth. Zoroark has a large, red, voluminous mane with black tips, tied into a ponytail, as a teal bangle down its length separates a mass of the mane from the lower portion. It has a black ruff on its upper body, pointed at the shoulders from which its arms extend. Its upper arms are thin, whereas its lower arms, while still slim, are bulkier. The arms have spiky extensions of fur at the elbows, and it has red claws on its hands and feet. Zoroark's eyes are red-rimmed with light blue irises.

Zoroark can create illusions that are indistinguishable from reality, deluding many people simultaneously. It can even create illusory landscapes in the forests where it dwells, to hide its territory and protect its den. However, Zoroark is incapable of physically changing itself into another form; it is merely capable of casting illusions. When a Zoroark takes the form of a human, it is capable of human speech. It can make convincing illusions of attacks, and these illusions are extremely realistic, enough to fool even cameras and make one believe they're being physically affected, though the illusion does not have any direct physical effect. Lonely Trainers tend to use Zoroark to create illusions in order to ease their own burden of solitude. There are stories of Zoroark punishing people who tried to capture it with illusions.

Zoroark lives in groups, where unity is strong. It is extremely protective of those it cares about and will go to any lengths to keep them safe, including risking its own life, and it can hold grudges against those who harm its loved ones. Zoroark will hide its Zorua young in its mane to protect them and carry them around. There are stories that say Zoroark punishes those who attempt to catch it by trapping them in an illusion. Prior to Generation VII and in Generation IX, Night Daze is its signature move.

Zoroark, its pre-evolved form, Zorua, and their regional forms, are the only known Pokémon that can have Illusion as an Ability.

Forms

Zoroark has an ancient regional form: Hisuian Zoroark.

In the Hisui region, Zoroark takes on a drastic ghostly appearance due to dying from the harsh conditions and being reborn through spite. Its main body color is now disheveled with light gray with red and white accents. Hisuian Zoroark's head and face are similar to its Unova counterpart but colored gray. It has gray ears with black insides and two white markings on both sides of the face. The ears also have light red split parts. The long mane has changed into a longer mane that is colored white with the ends of each tips being colored light and dark red, while covering the right side of Zoroark's face. The arms and legs have several red spots and light red fur that dangles around. The claws and toes of Zoroark are colored black. The eyes are now red with yellow sclera.

As a result of its appearance, Hisuian Zoroark was said to resemble an embodiment of death. The illusions channeled through Hisuian Zoroark's long withering fur are full of spite. Uniquely, this spiteful illusion can cause physical harm to its opponent on both the inside and outside. This power comes from the hatred it has for every living thing in the world. Hisuian Zoroark's illusion malice is powerful enough to drive anyone who sees it to insanity due to their terror. Hisuian Zoroark recklessly attacks its foes or nemeses, to the point its own bitter energy can cause physical harm onto itself. Despite its extremely hostile and aggressive nature to everything, Hisuian Zoroark can be compassionate to those it cares about, however, such as Hisuian Zorua, and it will become an invaluable ally once someone earns its trust. Hisuian Zoroark prefers to reside in the cold areas where it lingers onto. Like its Unova counterpart, Hisuian Zoroark can make its illusion of humans talking, to the point of easily fooling anyone in order to get food.

Hisuian Zoroark and Zorua are the only known Pokémon capable of learning the move Bitter Malice.
