Is Aron Good in Sword & Shield Playthrough?

Aron shows up in the Crown Tundra DLC. Steel/Rock evolving into Aggron at level 42 is a long road, but the defensive typing resists Normal, Flying, Bug, Rock, Ice, Dragon, Fairy, and Psychic. Postgame DLC timing limits story use, but Aggron is a solid physical wall for Crown Tundra content.

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.

SwSh Aron Best Moveset

Steel/Rock with 100 Defense is bulky for a pre-evo but 50 HP undercuts it and 30 Speed goes dead last. AbilitySturdy guarantees surviving one hit from full, the only competitive trait here. The moveset waits for Aggron's 110 Attack and 180 Defense.

Pokedex Entry

It eats iron ore—and sometimes railroad tracks—to build up the steel armor that protects its body.

When Aron evolves, its steel armor peels off. In ancient times, people would collect Aron’s shed armor and make good use of it in their daily lives.

Aron Sword & Shield Guide

  • For Sword & Shield, you can run Aron through the first few routes without issues. 330 BST won't carry you far though. Get it to Lairon as fast as you can.

Game Availability

Available in 15 titles since its debut in Ruby & Sapphire, Aron spans 8 generations of Pokemon games. It's accessible through catching or hatching as a base form in most mainline games.
