While seeking iron for food, it digs tunnels by breaking through bedrock with its steel horns.

Type-wise, Aggron takes extra damage from Fighting, Ground, and Water. Watch out for Fighting and Ground attacks, those deal 4x damage. Poison moves do nothing thanks to a full immunity. 8 resistances give it solid defensive coverage on top of that. Aggron's physical bulk (base 180 Def) helps cushion physical weakness hits, but special attackers are the bigger threat.

Hard to wall, honestly. Aggron threatens 11 types beyond its own STAB, with Normal and Ice standing out. Pair that with Head Smash and Steel Beam and switchins need to think twice.

Aggron isn't available in the wild in Legends: Z-A. Start by transferring Aron from Ruby, Emerald, or Brilliant Diamond. The evolution path from Aron to Aggron is covered in the steps below.

How to Obtain Aggron in Legends: Z-A

  1. Lairon
    Step 2Evolve into Lairon
  2. Aggron
    Step 3Aggron
  • Aggron has a 530 base stat total and ranks as C-Tier: a situational pick that fills a niche. It works best as a balanced. Base 180 Defense is where it shines.

  • Aggron's biggest threats include Machamp (Fighting), Golem (Ground), and Swampert (Water), all carrying super-effective STAB moves. Machamp is the most dangerous since Fighting moves deal 4x damage. Aggron has enough bulk to absorb a hit, but don't push the matchup. Pivot to a teammate that resists.

  • Sturdy is the go-to ability for Aggron. It prevents being KOed from full HP, leaving 1 HP instead. Its hidden ability Heavy Metal can work in specific setups. Rock Head is the other option. Pick based on what your team needs.

  • Aggron fills the balanced role. It's a physical attacker with base 110 Attack. Base 50 Speed is low. Priority moves or Trick Room are the way to go. And it's tanky enough to absorb a few hits.

  • Best way to handle Aggron: Super-effective STAB from faster Pokemon is the simplest answer. Fighting, Ground, and Water-type attackers hit hardest.

Aggron first appeared in Ruby & Sapphire and has been available in 15 games across 8 generations. Obtainable through wild encounters in most titles where it appears.
