Wimpod is a small, arthropod Pokémon. Its main body is purple and is covered by silver plating across its back. There are four plates total. The first plate covers half of its head, but leaves room for its eyes. The upper lids for its eyes appear to be covered with additional plating. The three plates on its back overlap, and each has a single black triangle in the middle. It has a long spike on each side of its head that curves backward, large yellow eyes with two short extensions over them like eyelashes, and two flat antennae that extend over its back. There are four short legs on its underside, and it has a long, prickly tail.
