Hippowdon is a large, hippo-like Pokémon with skin color based on its gender. It is light brown if male, and black if female. It has a dark gray back and muzzle with several holes in them. Sand often spills out of the ports on its back and its nostrils. This sand is stored internally, and is used to create twisters when attacking. It has a large, rounded snout, a mouth filled with peg-like teeth, and red eyes. Hippowdon has black feet with four blunt claws each. It is short-tempered, and may hold its mouth agape as a display of strength. Hippowdon's massive jaws are capable of crushing cars.
