Like all Mega Evolutions, Mega Aggron can’t be directly caught in Pokémon Go. Instead, you need to keep defeating it in Mega Raids until you’ve collected enough Mega Aggron Energy for its evolution. Below you’ll find Mega Aggron’s counters and weaknesses to help you succeed in Pokémon Go - just remember you need to have an Aggron in your Pokémon storage to conduct its Mega Evolution. On this page:
Mega Aggron type - Steel type Mega Aggron is weak against - Fire, fighting and ground types Mega Aggron counters - Entei, Shadow Ho-Oh, Moltres and Reshiram for fire-types; Machamp, Lucario and Conkeldurr for fighting types; and Garchomp or Mamoswine for ground types. Other Mega Aggron notes - As a pure steel type, you have multiple opens for counters - with ground types being the most commonly available, while fire has a handful of powerful options, especially if you have a fully levelled Shadow Ho-Oh. Remember to Mega Evolve someone like Charizard to add a type-related damage boost to the party as well!

According to the official Pokédex entry, “Aggron has a horn sharp enough to perforate thick iron sheets. It brings down its opponents by ramming into them horn first.” Mega Aggron, meanwhile, is a pure steel-type, dropping the double weakness to fighting in the process. It also sounds a little more aggresive, according to its own unique Pokédex entry: “Aggron claims an entire mountain as its own territory. It mercilessly beats up anything that violates its environment. This Pokémon vigilantly patrols its territory at all times.” Good luck defeating Mega Aggron in Pokémon Go!
