Espurr is a bipedal, feline Pokémon. Its fur is a pale gray with white tips on its ears and white paws. There are tousled tufts of fur on its head, cheeks, shoulders, chest, and hips. It has wide, pale purple eyes with darker purple pupils, a tiny nose, and a small mouth. When its mouth is open, two pointed teeth can be seen on its upper jaw. Its tail is fluffy and slightly curled. Espurr's ears are quite large in proportion to its body and folded. Beneath its ears are two ring-shaped yellow organs. These organs emit Espurr's intense psychic powers. It has no control over its power, and it would leak out if the ears were not sheltering the organs. It has enough psychic energy to create a blast radius of 300 feet (90 meters). This psychic energy can send even a wrestler flying. While its blank expression barely changes, beneath it is an intense struggle, trying so hard to control its psychic powers. Espurr can fall unconscious if its psychic power builds up too much.
