Rhyperior

Rhyperior (Japanese: ドサイドン Dosidon) is a dual-type Ground/Rock Pokémon introduced in Generation IV. It evolves from Rhydon when traded while holding a Protector. It is the final form of Rhyhorn. Rhyperior is a large, brownish-gray Pokémon with two horns, a larger one on its nose and a smaller one above it; the upper horn is smaller on a female Rhyperior. It has orange, rocky plates covering parts of its body, blade-like protrusions on its elbows, and holes in its palms that act as cannons, allowing it to fire rocks and boulders, sometimes even accidentally launching Geodude. Rhyperior has a tough carapace, able to withstand volcanic eruptions, and deflect most attacks before counterattacking with its drill-like horn. It lives in mountains and is known for its powerful physical attacks, though its special defense and speed are low, making it vulnerable to special attacks.
