Mega Aggron may look like a fearsome raid boss, but this Pokemon GO battle isn’t all that challenging with the right Pokemon. If you’re looking to capture Aggron or just want to store up some precious Mega Energy, here are the best Mega Aggron counters in Pokemon GO.
Mega Aggron Weakness & Type Effectiveness
Since Mega Aggron is a pure Steel-type Pokemon, players will have a pretty easy time narrowing down the potential pool of Pokemon to use in battle. These should include Pokemon who resist Dragon, Rock, Steel, or Electric-type moves and who have strong Fighting, Fire, or Ground-type moves.
| Pokemon | Type | Vulnerable To | Strong Against | Resistant To |
|---|---|---|---|---|
 Mega Aggron | Steel | Fighting Ground Fire | Fire Ice Flying Bug Dragon Rock Fairy Water | Normal Grass Ice Flying Psychic Bug Rock Dragon Steel Fairy |
We recommend bringing Ground or Fighting-type Pokemon, as Ground resists Electric and Rock-type moves, and Fighting resists Rock-type moves. Fire, while great for attacking, is vulnerable to Rock-type moves, which Aggron favors.
Best Mega Aggron Counters in Pokemon GO
Below is a list of the top 10 best counters for Mega Aggron, and they may look a bit familiar. Of course, they all are either Ground or Fighting-type with some Fire-types mixed in. But they are also several of the strongest Pokemon that make it onto several counter lists.
| Pokemon | Moves |
|---|---|
 Primal Groudon | Mud Shot Precipice Blades |
 Mega Blaziken/ Blaziken (Shadow) | Counter Blast Burn |
 Excadrill (Shadow) | Mud-Slap Scorching Sands |
 Mega Garchomp/ Garchomp (Shadow) | Mud Shot Earth Power |
 Terrakion | Double Kick Sacred Sword |
 Machamp | Counter Dynamic Punch |
 Reshiram | Fire Fang Fusion Flare |
 Lucario | Counter Aura Sphere |
 Rhyperior (Shadow) | Mud-Slap Earthquake |
 Hariyama (Shadow) | Counter Dynamic Punch |
If you stick to the Pokemon listed above and they have a CP higher than 3,500, we think you can skim by with two to three trainers. Of course, the trainers you bring into battle will also need a kitted team of proper Mega Aggron counters.
