This Pokémon's sturdy carapace protects it from volcanic eruptions. It shoots round rocks from the holes in its hands.
A Rhyperior's brain is smaller than a Rhydon's, but the Rhyperior is stronger because it spends more energy on battling and less on brainpower.
This Pokémon evolved through use of a curious item. Its rocklike hide is composed of a mysterious substance and can withstand a blow from a masterwork sword with nary a scratch.
