Rhyperior (Japanese: ドサイドン Dosidon) is a dual-type Ground/Rock Pokémon. It evolves from Rhydon when traded holding a Protector. It is the final form of Rhyhorn.
Rhyperior has basically the same build as its predecessor, Rhydon, although it is taller, heavier, and has an additional horn. Rhyperior has a club-like tail and its hide is partially covered by orange, rocky plates. Rhyperior has blade-like protrusions on its elbows and has holes in the palms of its hands which works as a cannon or a gun. Rhyperior's body is a brownish-gray as opposed to just regular gray. It also appears to have two thick, rectangular rocks above its eyes, resembling heavy eyebrows.
