Nickit is an orange-maroon fox-like Pokémon with a slender body and a large head relative to its body size. It has long, black ears, white spots on its head that resemble eyebrows, and small dots around its eyes that gives the appearance of tears and mask-like markings around its yellow eyes. Nickit also has tufts of furs on both sides of its head. It has a white belly and chest, its feet are black, and its tail is long with a black tip resembling a sack.
A cunning thief, Nickit enjoys stealing food from others instead of spending their time finding food on their own. They have incredibly soft pads that compress lightly when in contact with the ground, allowing them to move silently without notice. They can use their tails to sweep their paw prints so it can be hard to locate them. It has a fierce rivalry with Purrloin.
