Rhydon is a large, gray, bipedal Pokémon with an amalgam of features from dinosaurs and rhinoceroses. Rhydon's most famous feature is the cream-colored, drill-like horn on its snout, although there are other protrusions on the head as well. These include the front-pointing crest extending from the middle of its head, two triangular, ear-like features to the sides of the crest, a wavy-shaped, also ear-like extension further down its head, and the spiky ridges on the sides of its mouth. It has a long tail with skinny, black stripes. Rhydon has a cream-colored stomach and a ridged back.
