Aron sits at the start of its evolution line — not yet at full power, but that changes fast. Most trainers push through to Aggron as fast as possible. Known as the Iron Armor Pokemon. Built to hit on the physical side.
Defense and Attack carry most of Aron's stat budget. Speed's the obvious dump stat. Common in the wild and yields 1 Defense EV. Follows a slow 1.25M XP grind.
This Pokémon has a body of steel. To make its body, Aron feeds on iron ore that it digs from mountains. Occasionally, it causes major trouble by eating bridges and rails.
Aron has a body of steel. With one all-out charge, this Pokémon can demolish even a heavy dump truck. The destroyed dump truck then becomes a handy meal for the Pokémon.
Aron Weakness
GoodAron is weak to Fighting, Ground, and Water-type moves. 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.
Three stages ahead. Aron grows into Lairon, then pushes on to Aggron. Check the evolution methods below. For breeding, slow to hatch with no compatible partners via one egg group. Evolving adds up to 200 stat points total.
How to Evolve
Breed Aron from the Monster egg group. Pass egg moves like Body Slam, Curse, Dragon Rush and 9 more to offspring.
Aron runs a standard attacker set. Hardy nature with flexible EVs EVs shapes the build, while Shellbell brings extra utility. Sturdy supports the kit from the background.

Best Locations
Aron's encounter pool splits between Alpha Sapphire and Omega Ruby. You've got 14 walking spots at Lv. 6-20 total, but your version determines which ones actually show up.
Aron is meant to evolve into Lairon. At 330 BST, the stats aren't there for competitive play yet. Pre-evolution Pokemon rarely hold up against fully evolved threats.
Aron's biggest threats include Hitmonlee (Fighting), Rhydon (Ground), and Gyarados (Water), all carrying super-effective STAB moves. Hitmonlee is the most dangerous since Fighting moves deal 4x damage. At base 30 Speed, Aron won't outrun any of these threats so switching to a resist is usually the safer play.
Aron evolves into Lairon at level 32. Aron is the base form in a 3-stage evolutionary line.
Sturdy is the go-to ability for Aron. It prevents being KOed from full HP, leaving 1 HP instead. Its hidden ability Heavy Metal can work in specific setups. Rock Head is the other option — pick based on what your team needs.
Base 30 Speed is low. Priority moves or Trick Room are the way to go. On offense, Aron is a physical attacker with base 70 Attack.
Aron appears in 15 games, including Ruby & Sapphire, FireRed & LeafGreen, and Emerald.
Available in 15 titles since its debut in Ruby & Sapphire, Aron spans 7 generations of Pokemon games. It's accessible through catching or hatching as a base form in most mainline games.
