How to Get Aron in FireRed & LeafGreen
No wild Aron in FRLG. Granite Cave in Hoenn is its home, so trading from Ruby, Sapphire, or Emerald is the starting point for the steel line.

Aron Weakness
Aron is weak to Fighting, Ground, and Water. Watch out for Fighting and Ground attacks, those deal 4x damage. On the flip side, it's immune to Poison-type moves entirely. With 9 resistances, the defensive profile is strong. Aron's physical bulk (base 100 Def) helps cushion physical weakness hits, but special attackers are the bigger threat.
| Damage | Types |
|---|---|
| 4x (Critical) | Fighting, Ground |
| 2x (Weak) | Water |
| 0.5x (Resist) | Ice, Psychic, Bug, Rock, Ghost, Dragon, Dark |
| 0.25x (Resist) | Normal, Flying |
| 0x (Immune) | Poison |
- Dark and Steel types added — Fairy does not exist yet
- Moves are Physical or Special based on type, not per move
