Registeel is a large robotic Pokémon. Most of Registeel's body is spherical and gray while the middle of its face has the appearance of being exposed as it shows black "skin" and is surrounded by raised metal. Registeel's lower half is disc-like in shape and has two cylindrical legs without toes. Its face consists of seven red dots in a hexagonal formation, and it has black arms with three fingers each that are connected to its upper half by gray hemispherical shoulders. The backs of its hands have three red triangles pointing away from the fingers.
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. While one Pokédex entry noted that the material that forms Registeel's body is extraterrestrial, it is also theorized that Registeel was actually born inside the Pokémon world's mantle, before emerging onto the surface 10,000 years ago. Further evidence supporting this theory is the fact that Registeel's body was tempered by pressure underground over thousands of years; as a result, it cannot be scratched. Another theory posits that Registeel was created by Regigigas out of magma. It is unknown what Registeel can eat. It was sealed away in ruins by people during ancient times.
