Rhydon, known as the Drill Pokémon, is a large, gray, bipedal Pokémon with features of 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.
Rhydon was the first Pokémon to be created. Rhydon's drill-horn is capable of crushing uncut diamonds, and it can knock down a building with one strike of its tail. Rhydon's rocky hide is strong enough to withstand direct cannonball fire, and serves as such effective protection that it makes Rhydon capable of living in molten lava up to 3,600 degrees. However, its rugged hide also makes it insensitive. Rhydon is apparently much smarter than its pre-evolution, evidenced by its ability to stand on its hind-legs. Despite this, it is still very forgetful.
