Lairon feeds on iron contained in rocks and water. It makes its nest on mountains where iron ore is buried. As a result, the Pokémon often clashes with humans mining the iron ore. It habitually shows off its strength with the size of sparks it creates by ramming its steel body into boulders. It loves iron ore. Groups of them fight for territory by bashing one another with their steel bodies.
