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. Its height is 7'10" and weight is 623.5 lbs.
The upper horn on a female Rhyperior is smaller than a male's.
Rhyperior can insert rocks and boulders into its arms through holes in its hands and then fire them like bullets. However, it will occasionally insert and fire Geodude by accident. They are monstrously powerful and are massively difficult to take down without a Water or Grass move.
It puts rocks in holes in its palms and uses its muscles to shoot them, although Geodude may be shot at rare times.
Rhyperior live far up in the mountains. Finding a wild one can be difficult.
