Lairon
Ruby

LAIRON tempers its steel body by drinking highly nutritious mineral springwater until it is bloated. This POKéMON makes its nest close to springs of delicious water.

Sapphire

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.

Emerald

When two LAIRON meet in the wild, they fight for territory by bashing into each other with their steel bodies. The sound of their collision carries for miles.

Firered/Leafgreen

It habitually shows off its strength with the size of sparks it creates by ramming its steel body into boulders.
