Krabby is a crustacean Pokémon with a strong outer shell protecting its small body. Its upper half is red and has its eyes and two small spikes on the top of its head. Its light tan arms are also connected to its upper body. Its lower body is light tan and doubles as its jaw with two fangs overlapping its upper body. Its hips are visible on the lower front of its body connected to its four long, thin legs. Each leg has a single, claw-like foot. The main features of Krabby's body are the two large, red pincers at the end of its arms. Krabby uses them as its main form of offense, and as a form of balance. Sometimes, Krabby may lose a claw during battle or have a damaged claw forcibly removed. However, the claw regenerates over a short period.
In the wild, Krabby lives near the edge of water in both fresh and salt water. Krabby is most commonly found on beaches where it burrows in the sand. In times of scarce food sources, it may eat sand to regain nutrients and will be very aggressive in defending its home. Its main form of defense is creating foam to shroud its body, in order to confuse opponents into thinking that it is bigger than it actually is. As seen in the anime, Krabby generally keeps to itself, but will quickly defend itself if provoked. In the past, Crabhammer was its signature move.
