Mega Aggron

It is a pure Steel-type Pokémon that is vulnerable to Fighting-, Fire-, and Ground-type attacks. It drops its secondary Rock-typing upon Mega Evolving, which makes it gain key weaknesses to Fighting and Ground, alongside a standard weakness to Fire. A well-prepared team of high-DPS Fighting-, Fire-, or Ground-type Pokémon can bring it down efficiently.

Bringing the right counters will make all the difference if you are planning to farm Mega Energy, hunt for a shiny, or simply add Mega Aggron to your collection.

Best Mega Aggron Counters

The following are the top Pokémon that deal supereffective damage to Mega Aggron.

POKÉMON	RECOMMENDED MOVESET
*Mega Lucario*	*Force Palm* as a Fast Attack and *Aura Sphere* as a Charged Attack
*Primal Groudon*	*Mud Shot* as a Fast Attack and *Precipice Blades* as a Charged Attack
*Mega Blaziken*	*Counter* or Fire Spin as a Fast Attack and *Blast Burn* or *Aura Sphere* as a Charged Attack
*Mega Garchomp*	*Mud Shot* as a Fast Attack and Earth Power as a Charged Attack
*Shadow Groudon*	*Mud Shot* as a Fast Attack and *Precipice Blades* as a Charged Attack
*Shadow Heatran*	*Fire Spin* as a Fast Attack and *Magma Storm* as a Charged Attack
*Lucario*	*Force Palm* as a Fast Attack and *Aura Sphere* as a Charged Attack
*Shadow Excadrill*	*Mud-Slap* as a Fast Attack and Scorching Sands as a Charged Attack
*Shadow Garchomp*	*Mud Shot* as a Fast Attack and *Earth Power* as a Charged Attack
*Shadow Conkeldurr*	*Force Palm* as a Fast Attack and *Dynamic Punch* as a Charged Attack

Note that Mega Lucario and Primal Groudon remain among the strongest overall Mega Aggron raid attackers thanks to their exceptional damage output and Mega Boost support for teammates.

Best Budget Counters

Not everyone currently has access to high-tier Shadow Pokémon or Primal/Mega legendaries. Fortunately, Mega Aggron’s weaknesses make it accessible with strong non-legendary options. Excellent budget choices are as follows:

Machamp with Counter as a Fast Attack and Dynamic Punch as a Charged Attack.
Excadrill with Mud-Slap as a Fast Attack and Scorching Sands or Earthquake as a Charged Attack.
Conkeldurr with Counter as a Fast Attack and Dynamic Punch as a Charged Attack.
Blaziken with Counter as a Fast Attack and Blast Burn as a Charged Attack.
Darmanitan with Fire Fang as a Fast Attack and Overheat as a Charged Attack.
Rhyperior with Mud-Slap as a Fast Attack and Earthquake as a Charged Attack.

Mega Aggron Raid Tips

Having the best counters may not be enough. You also need a good strategy. The following tips will help you a great deal:

Lead with a Mega Fighting, Ground, or Fire Pokémon to boost teammates’ corresponding attacks.
Coordinate Mega Evolutions with your raid group for maximum efficiency.
Use Pokémon with matching Fast and Charged Moves (e.g., full Fighting or full Ground sets).
Revive and rejoin if necessary rather than using weaker backup teams.
If you can, battle Mega Aggron during Sunny/Clear (boosts Fire and Ground) or Cloudy (boosts Fighting) weather conditions in-game for an extra damage edge.

How Many Trainers are Needed?

Due to Mega Aggron’s massive defense stat, it is much bulkier than standard raid bosses. In most situations, 3 to 5 prepared trainers with strong optimal counters at high levels are recommended to comfortably defeat Mega Aggron. Lower-level trainers or those relying on budget counters will want a larger group of 5 to 7 players.

Hundo CP for Aggron from Raids

You will get rewards such as Aggron Mega Energy, other items, and an encounter with regular Aggron after completing the Mega Raid successfully.

The hundo CP (i.e., the perfect IV CP) for Aggron caught from raids depends on the in-game weather condition when it was caught:

If caught during Snowy (boosts Steel) or Partly Cloudy (boosts Rock) weather conditions, the hundo CP is 2143 CP.
Otherwise, the standard hundo CP (Level 20) is 1714 CP.

If you get a good one, teach it Smack Down as a Fast Attack and Meteor Beam as a Charged Attack.

Mega Aggron is a formidable defensive raid boss, but its clear-cut vulnerabilities to Fighting, Fire, and Ground types give well-prepared trainers a clear path to victory. Make sure to gather a group of 3 to 5 players, gear up with top counters like Mega Lucario or Primal Groudon, and take advantage of the raid window between July 29 and August 4 to stock up on Mega Energy and hopefully secure a shiny or hundo!
