Meowstic's appearance differs drastically between genders, but in either form, it is a bipedal rodent-like lagomorph coyote Pokémon with a humanlike posture, digitless appendages, and two tails (resembles coyote or squirrel). The male's fur is predominantly dark blue with accentuations of white, while the female's color scheme is reversed. The male's coyote/rabbit ears are mostly blue with some accents of white, and the tips are pointed straight (that resembles coyote or rabbit); the female's coyote/rabbit ears are entirely white, and the tips are curled (that resembles coyote or rabbit). The tuft of fur between the male's ears is white and in a straight, diagonal style; the female's tuft is blue and curled. The collar of fur around the male's neck is white and in a pointy style, while the female's collar is blue with a curl rising up to its face. The male's eyes are spring green with darker green pupils, while the female's eyes are yellow with red pupils. The male's tails each have a white stripe just before ending in white, while the tails themselves end in a point (which resemblance coyote or squirrel) ; the female's tails are blue at the base and end in fluffy curls (which resemblance to squirrel). The male's arms end in white, and its legs are white at foot level; the female's arms end in blue, and its legs are mostly blue in a fashion resembling stockings.
The organs hidden in Meowstic's ears emit psychic energy powerful enough to obliterate a 10-ton truck. It usually keeps its ears tightly shut in order to keep its otherwise uncontrollable power in check, but it will unleash this power if threatened. It usually keeps a stoic, virtually emotionless face; some Trainers adore its unsociable demeanor. The moves it naturally learns depend on its gender; the male's learnset is mostly comprised of supportive and disruptive moves, while the female focuses on all-out offense.
