Stats & Training
The stat bars tell the story: Defense carries everything and Speed's dead weight. But this Iron Armor Pokemon still yields 2 Defense EVs per fight on a slow 1.25M XP grind.
For food, it digs up iron ore. It smashes its steely body against others to fight over territory.

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 8 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.

Legends: Z-A Evolution
Lairon sits between Aron and Aggron in this three-stage line. Not the final form yet. For breeding, slow to hatch with a decent partner pool via one egg group. So far, Defense got the biggest boost (+40 from Aron). The final form adds another 100 stats on top. View every chain in the Evolution Chart.

The level-up pool tells the story here. Lairon learns Take Down and Iron Tail naturally, plus enough variety that TMs feel like bonuses. Normal and Ground coverage extends the reach beyond that.

How to Get Lairon in Legends: Z-A
Lairon can't be caught in Legends: Z-A. Transfer Aron from Ruby, Emerald, or Brilliant Diamond and evolve through the 2-stage line to get it. The step cards below map the full chain.
Lairon Guide
At 430 BST, Lairon is firmly in pre-evolution territory. Evolve it into Aggron before bringing it to any serious fight.
In Legends: Z-A, 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.
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.
