Lairon can have one of two abilities: Sturdy, which nullifies the effect of one-hit KO moves on it, and starting with Generation V, prevents it from being Knocked Out in one hit--if its HP is full, an attack that would have caused a KO will leave it with 1 HP; or Rock Head, which nullifies recoil from moves such as Double-Edge or Head Smash. Lairon from the Dream World have access to a third Ability, the Heavy Metal Ability. This ability doubles its weight in battle, affecting how much damage it would take from Grass Knot or Low Kick as well as how much damage it can deal out from the attack Heavy Slam.
Lairon is in the Monster Egg Group, and its Egg takes approximately 8,960 Steps to hatch. It takes Lairon 1,250,000 Experience Points to reach Level 100.
Lairon takes on the appearance of a large armadillo clad in armor. The armor has some spikes on it, resembling a Stegosaurus to some extent.
 Gender Differences
Lairon doesn't have any differences to differentiate between male and female.

 Anime/Manga Information
More recently, some Wild Lairon were amgonst the Steel-Types that went berserk in the two episodes that featured Iron Island Steeling Peace of Mind! and Saving the World from Ruins. Paul also used a Lairon against Brandon in the episode A Pyramiding Rage!. Unfortunately for Paul, his Lairon was a part of the wrong end of a 6-0 shutout, as Brandon's Regice, Regirock, and Registeel were dominant.

Lairon's Manga info is unknown at this time.
 Pokémon Information
 Competitive Battling
Lairon finds itself in the Never-Utilized Tier of Competitive Battling. Its very high Defense is pushed even higher with the Hold Item Eviolite, and combining Head Smash with the Rock Head Ability combines for a dangerous attacking combination without having to worry about Head Smash's 50% Recoil.
Lairon has terrible typing; while the combination has a number of resistances it leaves it twice as vulnerable to Fighting-and-Ground-Type moves. Even while holding Eviolite, it doesn't have a great Special Defense, something that Special Attackers can take advantage of.
