How to Get Aron in Ultra Sun & Ultra Moon
You're catching Aron first, not Aron. Aron appears in the wild in the encounters below. The step cards map the full 3-stage chain with evolution methods between each stage.
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 8 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, Dragon, Fairy |
| 0.25x (Resist) | Normal, Flying |
| 0x (Immune) | Poison |
