Dewott is a bipedal, otter-like Pokémon that is primarily light blue. It has small black ears, a pointed crest at the back of its head, a red nose, and long white whiskers forming tilted V-shapes. Two pointed teeth are visible in the upper jaw when its mouth is open. Its forelimbs have three fingers on each black paw. Around its waist is a large, dark blue, fringed arrangement of fur, with two scalchops on the thighs. These scalchops are detachable, and Dewott trains to use several techniques with them. Its feet and flat tail are black.
