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.

Mega Aggron counters and weaknesses in Pokémon Go

The fastest way to collect Mega Aggron Energy is to defeat one in Mega Raids. Below you’ll find the counters and weaknesses for Mega Aggron to help you achieve this:

  • Mega Aggron type - Steel-type
  • Mega Aggron is weak against - Fire, Fighting and Ground-type attacks
  • Mega Aggron is resistant to - Bug, Dragon, Fairy, Flying, Grass, Ice, Normal, Psychic, Rock and Steel-type attacks
  • Mega Aggron is super resistant to - Poison-type attacks
  • Mega Aggron Mega counters - Primal Groudon and Mega Lucario are your top two options, followed by Mega Blaziken (Counter/Blast Burn) and Mega Garchomp. If you don’t have any of these, Mega Charizard Y brings up the rear a reasonable Mega, but notably worse than the rest of this list.
  • Mega Aggron counters - If you have them, Shadow Groudon, Shadow Excadrill, Shadow Garchomp and Shadow Blaziken are all fantastic options. Failing that, Terrakion and Keldeo with Sacred Sword are your strongest options, followed by Groudon, Reshiram, Lucario and Therian (Sky Cat) Landorus.
  • Primal Groudon and Terrakion are your top two counters
  • Number of players to beat Mega Aggron - You’re looking at four Trainers with fully optimal 40 counters at the bare minimum. As always, the more the merrier.
  • Tactics - As a pure Steel-type, you have multiple options for counters. Primal Groudon is far and away your strongest option, but it is in a league of its own. After that, you're looking for Pokémon with Sacred Sword and then your strongest Ground, Fighting and Fire-types. There really are plenty of options, so don’t stress if you don’t have optimal counters!
Mega Aggron made its debut during September 2022's Test Your Mettle event.

Everything we know about Aggron

Aggron.
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. Long ago, there was a king who wore a helmet meant to resemble the head of an Aggron. He was trying to channel the Pokémon’s strength.'

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 is protective of its environment. If its mountain is ravaged by a landslide or a fire, this Pokémon will haul topsoil to the area, plant trees, and beautifully restore its own territory.'

Good luck defeating Mega Aggron in Pokémon Go!
