Mega Aggron is a Steel type Mega Raid boss. Best Mega Aggron raid counters include powerful Fire, Fighting, and Ground types, with a mixed range of different counters available to help you defeat it.

Mega Aggron Counters

Since Shadow Pokémon are extremely expensive to power up and require specific events to remove Frustration with a Charge TM, they will NOT be listed as raid counters in this article. That being said, if you have the shadow form of a listed raid counter Pokémon powered up and TMed, use it.

Best Mega Pokémon vs Mega Aggron

# Pokemon Fast Move Charge Move Time to win Deaths
1. Lopunny (Mega) Double Kick Fighting Focus Blast Fighting 493.33s 21.50


With pure Steel typing, excellent bulk, and decent moveset, Mega Aggron will prove difficult for unprepared trainers. Luckily, Steel-type counters are not hard to come by. The usual Fighting and Ground types will serve you well, as well as Fire types with a slight caveat.

Fighting will give you better overall damage due to access to powerful moves, while Ground will give you better resistances, resisting 1 out of 3 possible Fast Moves and 3 out of 4 possible Charged Moves that Aggron can learn. Fire types are great but you should be wary of Rock moves that Mega Aggron brought from its non-Mega days.

You’ll notice that Terrakion recently became the best Fighting-type attacker with Low Kick. If you don’t have Terrakion, you should still be able to whip up a strong team of counters, like Machamp, Conkeldurr, and Excadrill.

Mega Aggron Moveset Analysis

Fast Moves Charge Moves
  • Iron Tail Steel
  • Smack Down Rock
  • Dragon Tail Dragon
  • Heavy Slam Steel
  • Stone Edge Rock
  • Thunder Electric
  • Rock Tomb Rock

For optimal DPS Iron Tail and Heavy Slam are your best choices, as they also get STAB. While Mega Aggron does have Rock type moves, since it loses the typing upon evolution, it also loses its STAB on them, which is not optimal since it doesn’t give any Mega Boost for that type. To make best use of Mega Aggron keep it as a Steel type attacker.

How to Get Mega Aggron

You cannot catch Aggron in its mega evolved form from the raid. The mega raid boss is always catchable in its base form and as such, the CP ranges are for a regular Aggron.

Aggron can be caught with the following CP values:

  • 1636 – 1714 CP no weather boost
  • 2045 – 2143 CP boosted by Snow weather boost

In order to get Mega Aggron you will need 200 Mega Energy for the initial evolution, then 40 Mega Energy to evolve the same Aggron again in the future. If you wait for their ‘cooldown’ period to end, Mega Evolution is free. This cooldown period is shorter the higher mega level your Mega Pokémon is. Mega Energy can be obtained via Mega Aggron Raids, and once you have evolved Mega Aggron, you can earn 5 Mega Energy per candy while walking it as your buddy. You can walk any Aron, Lairon, or Aggron to earn Mega Energy, as long as you have previously evolved one to register it to your Mega Pokédex.

Shiny Aggron

Like all Mega Raid Bosses, you can catch the shiny version of Aggron from a raid.

If you think Mega Steelix is bulky in raids, you haven’t seen Mega Aggron. It has higher Defense and Attack than Steelix, so make sure you are well prepared going into these raids because it is going to take some hard hitters to beat it, especially if you are short manning.
