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.

ORAS Aggron Best Moveset

Mega Aggron drops Rock for pure Steel typing with AbilityFilter reducing super-effective damage by 25%%. 230 Defense behind a single typing with three resistances creates one of the hardest physical targets to break. The moveset earns C-tier through Mega defensive bulk, though 50 Speed limits offensive contribution.

Pokedex Entry

Aggron claims an entire mountain as its own territory. It mercilessly beats up anything that violates its environment. This Pokémon vigilantly patrols its territory at all times.

Aggron is protective of its environment. If its mountain is ravaged by a landslide or a fire, this Pokémon will haul topsoil to the area, plant trees, and beautifully restore its own territory.

Aggron Omega Ruby & Alpha Sapphire Guide

  • In Omega Ruby & Alpha Sapphire, Aggron has a 530 base stat total and ranks as B-Tier: a solid option in Omega Ruby & Alpha Sapphire for the right team. It works best as a balanced. Metalburst with Focus Sash is the standard set.

  • In Omega Ruby & Alpha Sapphire, 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 Omega Ruby & Alpha Sapphire, 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 Omega Ruby & Alpha Sapphire, 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.
