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 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.


  • Rhyperior and its pre-evolution share their species name with Nidoking and Nidoqueen. They are all known as the Drill Pokémon.
  • Rhyperior has the highest HP base stat among all Ground-type Pokémon.
  • Rhyperior's evolution line are the only Pokémon with the Rock/Ground combination to have Ground as its primary type.
  • Rhyperior and its pre-evolutions are the only Rock-type Pokémon that belong in the Field Egg Group.


It appears to draw much of its inspiration from a rhinoceros, aspects of various dinosaurs (such as ceratopsids and Ankylosaurus) and a tank. Its overall appearance also resembles a miner.

Name origin

Rhyperior is a combination of rhinoceros and superior.

Dosidon may be a combination of 土 do (ground/soil), 怒 do (anger), or ど do (prefix that makes a noun sound stronger), サイ sai (rhinoceros), and don (Ancient Greek for tooth, commonly used in the names of dinosaurs).
