Doryuzu

Doryuzu is a bipedal, mole-like Pokémon with a dark brown body with diagonal, red splotches. Three markings are on its front, resembling scratch marks, with two under each arm, and two on its back. It has short legs with small, narrow feet, each containing three toes. Its small white face is long and thin, tipped by its pink nose. Its eyes are set back, on either side of the bridge of the nose. Under them, on each side, are two thin, red stripes. A large blade roughly twice as large as its face extends from its forehead. The top of the blade contains two smaller blades, resembling fins. Its arms are thick and have three large blades instead of fingers, with two smaller blades on top of the middle ones.

On its knees, halfway down its arm, and just behind where its forehead meets its face, are small red spots.

Doryuzu can straighten its entire body, allowing it to spin like a drill. It has the ability to cut through iron and steel plating. Known as the "Drill King", it uses its excellent digging abilities to build a complex network of tunnels for its nest at more than 300 feet (100 meters) below the surface. Its tunneling can be both beneficial and harmful to humans, as it can help workers with its swift digging prowess, but it can be detrimental to underground structures, such as Subway tunnels.
