Clauncher is a cyan crustacean Pokémon with two yellow antennae atop its head. It has two claws: one claw forms a single, sharp point, while the other is significantly larger, with two parts, forming a classic pincer. The lower part of this pincer is smaller and yellow. It has black-grey stripes along the end of each abdominal segment and around its claws. It has four small cyan legs that are curved and come to a point. Clauncher has a light grey underside, three pointed mouthparts, round yellow eyes with a small, black pupil, and two small trapezoid tail-parts protruding from its lower abdomen. A horizontal line encompasses the front of its carapace, in line with its eyelids, up until a second vertical line that encompasses its carapace completely. It has light grey segments on the parts of its legs and claws closest to its body. Clauncher uses its larger claw to shoot compressed water like a pistol shot at its prey. Up close, the compressed water can shatter rocks.
