Steel-Type

Steel-type is one of the eighteen Pokémon types, originally introduced in Generation II. Steel-type Pokémon are physically weak to Fighting, Fire, and Ground-type attacks. Steel-type attacks are physically strong against Fairy, Ice, and Rock-type Pokémon. Steel-type has the strongest defenses of all of the types, being resistant to Bug, Dragon, Fairy, Flying, Grass, Ice, Normal, Psychic, Rock, and Steel-type attacks, and they also have an immunity to Poison-type attacks. Since being introduced in Generation II, some Pokémon introduced in Generation I have had their typings adjusted to Steel-type.
