Mega Aggron has returned to Pokémon GO’s raid rotation, and with its imposing defense and niche typing, it’s more than just a tanky roadblock—it’s a serious challenge that requires a well-planned counter strategy. Whether you’re aiming to collect Mega Energy, farm high-IV Aggron, or simply complete your Mega Dex, knowing how to efficiently defeat this Steel-type behemoth is essential.

This guide will break down everything you need to know about Mega Aggron, including its weaknesses, resistances, weather effects, and the most optimal Pokémon and movesets to bring into battle.

Mega Aggron Type Overview and Key Weaknesses

Mega Aggron is unique in that it sheds its Rock-typing and becomes a pure Steel-type when it Mega Evolves. This change drastically affects how you approach the raid. Steel-type Pokémon are notoriously resistant, and Mega Aggron exemplifies this with a staggering list of resistances.

🔒 Resistances:

• Bug

• Dragon

• Fairy

• Flying

• Ice

• Normal

• Psychic

• Poison

• Rock

• Steel

With such broad resistance coverage, players need to avoid bringing commonly strong attackers that fall into these categories. Focus instead on what hurts Mega Aggron the most:

⚔️ Weaknesses:

• Fire

• Fighting

• Ground

These three types are your golden ticket to shredding through Mega Aggron’s armor. Each offers powerful options with high DPS and advantageous moves.

Weather Strategy: Avoid the Snow

Mega Aggron benefits from Snowy weather, which boosts its Steel-type moves. Raiding under these conditions could make your battle longer and riskier. For the best odds, aim to fight under Sunny, Cloudy, or Clear conditions to take advantage of the boost for Fire, Ground, or Fighting-types instead.

Top Mega Aggron Counters for 2025

To reliably beat Mega Aggron, build your team around high-powered attackers of its three weaknesses, preferably those with STAB (Same Type Attack Bonus) to maximize damage. Here’s a rundown of the top-performing counters this season:

  • Fast Move: Fire Spin

  • Charged Move: Magma Storm
    A shadow variant with excellent Fire-type coverage and great durability.

  • Fast Move: Low Kick

  • Charged Move: Blast Burn
    Although less common, Shadow Emboar hits extremely hard.

🥊 Fighting-Type Counters

• Mega Lucario

  • Fast Move: Force Palm

  • Charged Move: Aura Sphere
    Lucario’s Mega form is devastating, especially when coordinating with other Fighting-types.

  • Charged Move: Blast Burn
    A dual Fire/Fighting-type that hits two of Aggron’s weaknesses in one package.

🌋 Ground-Type Counters

    A powerhouse in every Ground-based raid, Groudon is a top-tier option.

• Shadow Groudon

  • Fast Move: Mud Shot

  • Charged Move: Precipice Blades
    Slightly glassier than its Primal form but still potent.

Battle Tips for Mega Aggron Success

• Time Your Mega Evolution: Sync your Mega Evolution to not only boost your own attacks but also enhance those of your teammates. If using Mega Lucario or Garchomp, you’ll elevate the effectiveness of other Fighting or Ground-types.

• Use Revives Wisely: Mega Aggron may not deal massive damage quickly, but it can wear down attackers through attrition. Be ready to cycle back your strongest Pokémon.

• Optimize for STAB: As always, prioritize Pokémon using moves that match their typing to benefit from the Same Type Attack Bonus.
