Rhyhorn evolves into Rhydon at level 42. Rhyhorn is a Pokémon that resembles a rhinoceros, with a tough, plated exterior and a sharp horn on its nose.
While the characteristics of Pokémon change slightly in each version of the game, Rhyhorn is a consistent creature. It is known for its strength and toughness, but not for its intelligence, which is said to be very low. Rhyhorn, after gaining the required experience, can evolve into a Rhydon. This change gives the Pokémon the ability to stand on its hind legs as needed.
