Registeel is a large Legendary Pokémon. The top-half of Registeel's body is spherical and gray with a black stripe running down its "face". Its face consists of seven red dots in a hexagonal formation. It has black arms with three fingers each and cylindrical legs.
While Registeel has been classified as a Steel-type Pokémon, its body is hollow and made of a material that is harder than any known metal. However, this material stretches and shrinks despite its hardness. Registeel's body was tempered by pressure underground over thousands of years, as a result, it cannot get a scratch. It was sealed away in ruins by people during ancient times. It is unknown what Registeel can eat.
