Pokemon GO’s GO Fest Global 2025 event has plenty of featured Pokemon for Trainers to encounter, including several costume variants.
There are multiple types of Raids that range in difficulty, with 1 and 3-Star Raids being more commonly found Pokemon, 5-Stars being restricted to Legendary and Mythical Pokemon, and Mega Raids for Mega Pokemon. One such Mega Pokemon is none other than Mega Aggron, who is once again returning to Mega Raids betwen June 30, 2025, and July 8, 2025. Everything you’ll need to know about preparing for this Raid Boss has been outlined in the guide below.
Pokemon GO: Mega Aggron Weaknesses & Resistances
Mega Aggron is a pure Steel-type Pokemon in Pokemon GO, which gives it a specific set of weaknesses and resistances. To deal the most damage in battle, Trainers should focus on using Fire, Fighting, or Ground-type moves, as these are the types Mega Aggron is weak to.
In contrast, its Steel typing also grants it resistance to a wide range of attack types, including Poison, Dragon, Bug, Flying, Fairy, Normal, Ice, Psychic, Steel, and Rock. Because of this, it’s crucial to carefully choose your team and avoid relying on move types that Mega Aggron won’t be able to endure, as it is also quite a tanky battler.
Mega Aggron also gains boosted power through the Weather Boost mechanic when battling under Snow weather conditions. Players may wish to avoid Raids in these locations if possible, so as not to put themselves at a disadvantage against the boss.
Best Mega Aggron Counters in Pokemon GO
To choose the most effective counters for Mega Aggron Raids in Pokemon GO, Trainers need to consider its many resistances and build a team focused on exploiting its key weaknesses. Prioritizing Pokémon with strong Fire, Fighting, or Ground-type moves will give you the best chance at success. Trainers should also implement STAB when possible. STAB is the Same Type Attack Bonus — an effect that comes into play when the type assigned to the move a Pokemon uses matches one of the two possible types that the Pokemon holds.
Below, you will find a list of top picks when it comes to Mega Aggron counters, as well as recommended movesets to help you take the boss down. In the case that you do not have access to these Pokemon, you can simply use the list as inspiration for building your own team from similar specimens.
