Excadrill is a dark-colored, bipedal mole-like Pokémon. It has a tapered, pink-tipped snout and a white face. It has large, gray-colored, jagged features on its head and forelimbs, which may be described as looking like axes. Excadrill sports red diamond patterning on the side of its head, forelimbs, and legs, and larger, stripe-like patterns of red on its underside. Its head folds down behind its back, resembling a hood.
