Marshadow is a bipedal Pokémon that is gray. The area around its face resembles that of certain headgear such as a wrestler's mask or a helmet. The headgear can turn green when attacking or using its exclusive Z-Move. The bulbs on its arms can also turn green. It has orange eyes with golden yellow pupils. The spots above its eyes are the same color as its pupils. Marshadow has two trails of shadows coming out from behind its legs.Very few people have seen it, so its existence was the stuff of legends and myths.
