Krabit is a Pokémon based on both a River Crab and a Rabbit, the Pokémon has the general shape of a Rabbit however features several crab-like features, such as a hardened carapace on its back which is bright red, large claw-like protrusions on its hands including a backward facing one which when properly utilized allows it to crush nuts, berries and seeds between its claws as well as having a tail which is considerably longer and splits into four separate tails shortly after the base, each tail is considerably strong and allows the Pokémon to have a somewhat prehensile tail allowing it to move around at great speeds and swing through trees. The Pokémon's skin is reddish-pink in colour and while it does have striped of fur across its body particularly a large patch on its underbelly as well as around its ears, forehead and the rim of the carapace itself the Pokémon lacks fur on most of its body instead having a vaguely reptilian armour with hardened skin that appears to form a pentagon pattern across much of its body.
Krabit's eyes are almost entirely black with a brown-hue towards the center. Its snout is about as long in relation to its head as an actual rabbits however it points upwards towards the tip making the Pokémon appear to have a slight smile when looked at from the side, in addition its nose slightly protrudes out appearing somewhat akin to a button nose. Its muzzle is also more white towards the extremity than the rest of its body, this is also true for its limbs which are also white towards the hands and feet.
