Lairon Weakness
Fighting, Ground, and Water moves hit Lairon for super-effective damage. Fighting and Ground hits land at 4x, so they're the biggest threat. The upside? Poison-type moves can't touch it at all. It resists 9 types, so it can switch into a lot of moves safely. Lairon's physical bulk (base 140 Def) helps cushion physical weakness hits, but special attackers are the bigger threat.
| Damage | Types |

| 0.5x (Resist) | Ice, Psychic, Bug, Rock, Ghost, Dragon, Dark |
| 0.25x (Resist) | Normal, Flying |
| 0x (Immune) | Poison |
- Fairy type does not exist — Dragon has fewer checks

Lairon Black 2 & White 2 Guide
At 430 BST, Lairon is firmly in pre-evolution territory. Evolve it into Aggron before bringing it to any serious fight.
In Black 2 & White 2, watch for Blaziken (Fighting), Swampert (Ground), and Starmie (Water) when using Lairon. They all hit it super-effectively with STAB. Blaziken is the most dangerous since Fighting moves deal 4x damage. At base 40 Speed, Lairon won't outrun any of these threats so switching to a resist is usually the safer play.
Sturdy prevents being KOed from full HP, leaving 1 HP instead. That's the one you want on Lairon. Heavy Metal is the hidden ability. Niche, but it has its uses. Rock Head works too if your team needs something different.
Lairon is a physical attacker with base 90 Attack. Enough bulk to take a hit or two, too. Speed tells the real story. Base 40 Speed is low. Priority moves or Trick Room are the way to go. Fits the trick room role.
In Black 2 & White 2, For a casual playthrough, Lairon works as a placeholder. Steel/Rock coverage is useful early. The real payoff is Aggron. That's where the stats start mattering.
Game Availability
Debuting in Ruby & Sapphire, Lairon appears in 15 games across 8 generations. A reliable presence in most mainline games, typically found through catching or hatching as a base form.
