The bone at the end of Marororus's tail is incredibly solid, strong enough to shatter a boulder with a single swing. It travels alone, only interacting with others when it sees young Pokémon in need of protection.

Using its diamond-shaped crystals, it can instantly create a wall of ice to block an opponent's attack. A Marororus is the evolved form of a Cubone that has grown tough by overcoming the grief of losing its mother.
