It usually lives deep in mountains. But when it’s hungry, it shows up at the foot of the mountains and eats railroad tracks and cars.

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.

Leveling does the heavy lifting. Aron picks up Take Down and Iron Tail along the way, building toward a complete offensive set. TMs add Normal and Ground coverage, but the foundation's already strong by then.
