Stats & Training
Aggron's all-in on Defense at the expense of Speed. The physical lean is obvious from the bars. Yields 3 Defense EVs and follows a slow 1.25M XP grind.
While seeking iron for food, it digs tunnels by breaking through bedrock with its steel horns.

Aggron Weakness
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.

Sun & Moon Aggron Best Moveset
Aggron spreads damage across 3 coverage types. Custapberry provides extra utility to maximize each hit, and max Attack and Speed EVs push the math. Sturdy ties the set together while Ground, Normal, and Fighting coverage prevents safe switch-ins.

Hard to wall, honestly. Aggron threatens 13 types beyond its own STAB, with Normal and Ground standing out. Pair that with Head Smash and Iron Tail and switchins need to think twice.

How to Get Aggron in Sun & Moon
Aggron can't be caught in Sun & Moon. Transfer Aron from Ruby, Emerald, or Brilliant Diamond and evolve through the 3-stage chain to get it. The step cards below map the full chain.
Aggron Guide
In Sun & Moon, Aggron has a 530 base stat total and ranks as C-Tier: a niche pick in Sun & Moon's meta. It works best as a balanced. Firepunch with Custapberry is the standard set.
In Sun & Moon, yes. Mega Aggron hits 630 BST, a solid jump from the base 530. Hold the Mega Stone, trigger it in battle, and it lasts the whole fight. One Mega per team.
In Sun & Moon, 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.
In Sun & Moon, 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.
Game Availability
Aggron first appeared in Ruby & Sapphire and spans 15 games across 8 generations. It later gained a Mega form in Generation 6, adding new dimensions to its competitive identity.
