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 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.
