Pokémon Go Mega Aggron counters, weaknesses and moveset explained

How to defeat the mega evolved steel-type Pokémon.

Mega Aggron is the mega evolution for Aggron, which was released as part of 2022's Test Your Mettle event in Pokémon Go.

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.

Everything we know about Aggron

Aggron.
Regular, non-evolved Aggron.

Aggron is a steel and rock-type Pokémon from Gen 3, and is the second evolution in the Aron evolution chain.

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!
