Iron Boulder is a Gen 9 Legendary with a strong stat spread that holds up well. Rock/Psychic typing gives it a clear competitive identity. Its typing leaves 7 weaknesses to cover, which limits where it can switch in safely. It comfortably outruns most offensive threats.

Nothing fancy in Iron Boulder's spread. It leans physical with Speed out front. And you'll get 3 Speed EVs per KO for it. Follows a slow 1.25M XP grind.

Iron Boulder Weakness

Fragile

Stall teams hate this. Iron Boulder can spread damage across 10 types, with Normal and Fighting punishing common defensive pivots. STAB from Meteor Beam and Stone Edge keeps the pressure honest on everything else.
