Wartortle is a bipedal, indigo Pokémon similar to a turtle. It has brown eyes, a dark blue streak on each cheek, and two sharp teeth protruding from its upper jaw. It has three clawed fingers and pointed toes. Pale blue fur covers its long ears and tail. A brown shell with a pale yellow underside encases its body. A thick, white rim separates the upper and lower halves of the shell. As Wartortle grows old, its tail fur will darken, and it may have algae growing on its shell. The shell may also carry scars from past battles.
