Aggron Best Moveset
Mega Aggron drops Rock type entirely, becoming pure Steel at 230 Defense with AbilityFilter reducing super-effective damage by 25%. Held ItemAggronite and 140 Attack give the moveset real physical offense behind the highest non-legendary Defense stat available. Steel TermStab fires on 50 Speed cooldowns.
Rock/Steel had terrible defensive typing in Gen III (Ruby & Sapphire). 4x weak to Fighting and Ground. 180 Defense was amazing but those weaknesses negated it.

Physical Sweeper Moveset
- Fire Punch
- Earthquake
- Endeavor
- Counter
Recommended Teammates
No Mega form in Gen VIII (Sword & Shield). 180 Defense couldn't compensate for 4x weakness to the two most common offensive types in the format.

Aggron Weakness
Type-wise, Aggron takes extra damage from Fire, Fighting, and Ground. Poison moves do nothing thanks to a full immunity. 10 resistances give it solid defensive coverage on top of that. Filter reduces SE moves damage, further improving the defensive spread. Aggron's physical bulk (base 230 Def) helps cushion physical weakness hits, but special attackers are the bigger threat.
| Damage | Types |
|---|---|
| 2x (Weak) | Fire, Fighting, Ground |
| 0.5x (Resist) | Normal, Grass, Ice, Flying, Psychic, Bug, Rock, Dragon, Steel, Fairy |
| 0x (Immune) | Poison |

Yes. Mega Aggron hits 730 BST, a solid jump from the base 630. Hold the Mega Stone, trigger it in battle, and it lasts the whole fight. One Mega per team.
Filter is the go-to ability for Aggron. It decreases damage taken from super-effective moves by 1/4. It's Aggron's only ability.
Aggron fills the wallbreaker role. It's a physical attacker with base 140 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.
