Although it was initially unaware of the trio, Ash rushed up to it and antagonized it. In In the Pink, a pink Rhyhorn was the first Pokémon that Ash and his friends saw at Pinkan Island. By Mewtwo Returns, the Rhyhorn clone had bred a baby Rhyhorn with the clone of Fergus's Nidoqueen. In Mewtwo Strikes Back and its remake Mewtwo Strikes Back-Evolution, Corey's Rhyhorn was captured and cloned by Mewtwo. In Bulbasaur's Mysterious Garden, a Hiker used a Rhyhorn in a battle against Ash's Bulbasaur, which it lost. Rhyhorn evolves into Rhydon, which evolves into Rhyperior. Rhyhorn is powerful enough to shatter skyscraper or mountains instantly after charging forward with head tackles.

It does not care if obstacles get in the way, merely smashing through them or sending them flying, although it may feel pain the day after a collision. Due to its short legs, it is inept at turning and can only run in straight lines. However, it may recall the reason upon demolishing something. When it runs, it forgets why it started and continues until it falls asleep. Rhyhorn's brain is very small, giving it a one-track mind. In addition to its rocky hide, its bones are a thousand times harder than human bones. A female will have a shorter horn than a male. It has a triangular head with narrow, red eyes, two fangs protruding from its upper jaw, small, triangular openings on the upper sides, and a short horn on the tip of its snout.

Its underside and rear are smooth, and it has four short legs with two claws on each foot. Rhyhorn is a rhinoceros-like Pokémon with a body covered in gray, rocky plates. 5.7.5 By transfer from another generation.Refer to Game data→Evolution data for these details.)
