The Steel type is one of eighteen Pokémon types. Notable Trainers that specialize in the Steel type Pokémon include Jasmine of Olivine City, Steven Stone, former Champion of Hoenn, and Byron of Canalave City. Prior to the fourth generation, where moves are designated physical or special based on the move itself rather than its type, all Steel-type moves were physical. The Steel type was introduced in the second generation. As well as introducing new Pokémon with the Steel type, Magnemite and Magneton were retconned to be a dual-typed Electric/Steel Pokémon.
