Lairon (Japanese: コドラ Kodora) is a dual-type Steel/Rock Pokémon.

It evolves from Aron starting at level 32 and evolves into Aggron starting at level 42.

Biology

Lairon is a stocky, armored, Pokémon with four short legs. Its body is dark gray, and its eyes are sky blue. Its back is covered with segments of iron armor, each with a high ridge and round dark holes on the sides. The sides of its lower jaw have several flat protrusions, and two teeth are visible in its mouth. There are two pronged metal bands on its legs. The upper band is gray and the lower is silver.

Lairon smashes its steely body against others in battle over territory, and shows off its strength with the size of sparks it creates by ramming into rocks. It drinks nutritious mineral spring water and feeds on iron contained in rocks. It builds its nest on mountains where iron ore is buried, which results in it clashing with humans that are iron mining.

In the manga

Lairon in Pokémon Adventures

In the Pokémon Adventures manga

Main article: Rono

Rono, Sapphire's Aron, evolved into a Lairon before her challenge with Brawly in the Dewford Gym. Although it was, having newly evolved, her highest-level Pokémon, it failed to beat his Hariyama, but was put into good use against Aqua Admin Matt, beating his Pokémon and injuring him badly enough that he was not taken to the Seafloor Cavern sometime later. It evolved into an Aggron on Mirage Island as a result of the training Sapphire underwent alongside Ruby.

Name origin

Lairon may be a combination of lairy (slang for aggressive) or lair and iron.

Kodora may be a combination of 巨 ko (large) and dragon.
