Steel

The Steel type (Japanese: はがねタイプ Steel type) is one of the eighteen types. It was introduced in Generation II, along with the Dark type. As well as introducing new Pokémon and moves with the Steel type, two Pokémon were changed to have the Steel type. Steel-type moves are super-effective against Fairy-, Ice-, and Rock-type Pokémon, while Steel-type Pokémon are weak to Fighting-, Fire-, and Ground-type moves.
