Rhyperior is a large, brownish-gray Pokémon with two horns: one on its nose, and another one above it. The upper horn is smaller on a female Rhyperior. It has a club-like tail and its hide is partially covered by orange, rocky plates. It 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 can insert rocks and boulders into its arms through the holes in its hands and then fire them like bullets. However, it will occasionally insert and fire Geodude by accident. It also appears to have two thick, rectangular rocks above its eyes, resembling heavy eyebrows. Rhyperior lives far up in the mountains.
A Rhyperior owned by Forrest appeared in SS025, where it was used to battle against Nurse Joy and her Latias. However, the Eon Pokémon defeated the Drill Pokémon.

Sometime before the HeartGold & SoulSilver arc, Blue traded Silver his Rhydon after learning how to evolve it with a book written by Giovanni. It remained on Silver's team until sometime before the events of the X & Y arc, where it was returned to Blue.
Pokémon Ranger: Shadows of Almia: Rhyperior is used by Heath to protect the yellow circuit ball. Ice later borrows it to use in a three-way boss battle with Ice's Gallade and Lavana's Magmortar in the trio's efforts to thwart the player.
