📖 Introduction

Mega Aggron stands out for its high defensive stats, but its double weakness to Fighting-type attacks makes it easier to handle with proper counters.

The Mega Evolution of Aggron transforms this already durable Pokémon into an even more formidable raid boss in Pokémon GO. Mega Aggron loses its Rock typing when it Mega Evolves and becomes a pure Steel-type Pokémon, which significantly changes its strengths and weaknesses compared to its normal form.

While Mega Aggron has excellent defensive stats and many resistances, it also has clear weaknesses that trainers can exploit. Strong Fighting, Fire, and Ground-type attackers are especially effective against it, making Pokémon like Conkeldurr, Reshiram, and Groudon valuable raid counters.

Mega Aggron is useful because:

It boosts Steel-type attackers
It is extremely tanky and survives a long time in battles
It is useful in some niche PvP and raid situations

This raid guide will explain everything trainers need to know about defeating Mega Aggron, including its weaknesses, best counters, movesets, catch CP ranges, weather boosts, and raid strategies for both small and large raid groups.

🧠 Mega Aggron Raid Strategy

Mega Aggron is a pure Steel-type Pokémon with extremely high defense, making it one of the most durable Mega Raid bosses. Unlike glass cannon bosses, Mega Aggron can take a lot of damage, which means battles often last longer.

To defeat Mega Aggron efficiently, trainers should focus on using high DPS Pokémon that exploit its weaknesses while maintaining strong attack pressure throughout the raid.

🔥 Use Fire-type Pokémon to deal consistent super-effective damage
🥊 Fighting-types provide strong DPS and reliable counters
🌍 Ground-types can deal heavy damage and bypass defenses
👥 Coordinate Mega Evolutions for team-wide attack boosts

Raid Difficulty

This raid typically requires 3–5 trainers depending on player level, counters, and weather conditions.

💡 Expert Insight

Mega Aggron stands out as a highly defensive raid boss due to its pure Steel typing, which gives it numerous resistances and strong survivability. Unlike many Mega raids, it does not have a double weakness, meaning battles may last longer without properly optimized teams.

Its primary weaknesses to Fighting, Ground, and Fire-type attacks provide clear counter strategies, with Fighting-types often delivering the most consistent damage output. Using a Mega Evolution that boosts these types can significantly improve overall team performance.

For newer players, Mega Aggron may feel bulkier than expected, making group raids the safest option. Experienced trainers, however, can complete this raid efficiently by focusing on high DPS counters and maintaining steady pressure throughout the battle.

Mega raids also reward Mega Energy, making Mega Aggron a valuable target for long-term progression, especially for players looking to strengthen their Steel-type Mega roster.

Overall, Mega Aggron is less about raw difficulty and more about endurance, rewarding teams that balance damage output with consistency.

🗡️ Best Counters for Mega Aggron

Selecting the right counters is critical against Mega Aggron’s massive bulk. Fighting-type Pokémon with strong DPS moves are the best choice.

🥊 Fighting-Type Counters (Top Priority)

Fighting-type Pokémon are the most effective against Mega Aggron’s double weakness. Moves like Counter paired with Dynamic Punch or Close Combat deal massive damage. Mega Fighting-type Pokémon can provide a team-wide boost, increasing total raid efficiency.

Lucario: (Force Palm / Aura Sphere)

Fighting is super-effective vs Steel

Keldeo: (Low Kick / Secret Sword)

High DPS for short raid battles

Conkeldurr: (Counter / Dynamic Punch)

Fast energy generation with Counter

🔥 Fire-Type Counters

Fire-type Pokémon are strong secondary counters, exploiting Mega Aggron’s Steel typing. Fast moves like Fire Spin and charged moves such as Blast Burn deal consistent damage, but they are slightly slower than Fighting counters.

Blaziken: (Fire Spin)

Fire deals super-effective damage to Steel

Heatran: (Fire Spin / Magma Storm)

Many Fire Pokémon have high attack stats

Charizard X: (Fire Spin / Blast Burn)

Mega Fire Pokémon boost other Fire attackers in raids

🌍 Ground-Type Counters

Ground Pokémon can also deal super-effective damage to Mega Aggron’s Rock typing. These are useful if you don’t have a full Fighting or Fire team, but they may take more damage from Steel-type moves.

Groudon: (Mud Shot / Precipice Blades)

Extremely high Ground-type damage and raid boost

Garchomp: (Mud Shot / Earth Power)

Ground hits Steel for super-effective damage

Excadrill: (Mud Slap / Scorching Sands)

Many Ground Pokémon have very high attack stats

🔥 Why Fire, Fighting & Ground Counters Are Best

Mega Aggron’s Steel typing makes it weak to Fire, Fighting, and Ground-type attacks. These types are effective because they directly counter Steel’s defensive strengths.

Pokémon like Blaziken, Lucario, and Groudon perform exceptionally well because they combine high damage output with strong type advantages.

🔥 Fire-types melt Steel defenses quickly
🥊 Fighting-types deliver fast and powerful attacks
🌍 Ground-types deal heavy charged move damage

Intermediate	4–5 players
High-Level	2–3 players

Strong teams with optimized counters can complete this raid efficiently despite its high bulk.

💊 Revive & Potion Cost

Average revives used: 8–14
Average potions used: 10–18
Dodging significantly reduces resource usage
Using Mega Pokémon reduces total relobbies

❌ Common Raid Mistakes

Avoid using fragile Water or Ice attackers—they'll often be outpaced by Aggron's high damage. Also be cautious with Ghost types if Aggron runs Crunch.

🎯 How to Catch Mega Aggron Easily

After defeating Mega Aggron, use these tips to improve your catch success rate:

🟡 Use Golden Razz Berry for maximum catch chance
🎯 Aim for Excellent Curveball Throws
⏳ Wait for attack animation before throwing
🌀 Use curveball technique for better catch probability

Consistent throws combined with proper timing will make catching Mega Aggron much easier.

🧩 Best Team Compositions

Lead with strongest Fighting-type attacker
Follow with two additional Fighting Pokémon
Add one Fire-type attacker for backup
Finish with Water- or Ground-type Pokémon for coverage

Avoid Steel- and Rock-type Pokémon for offense, as Mega Aggron resists those moves.

Best Team (3–5 Trainers)

Mega Lucario
Primal Groudon
Mega Blaziken
Shadow Heatran
Mega Garchomp

Alternate Team (Balanced)

Terrakion
Keldeo
Shadow Groudon
Shadow Excadrill
Shadow Conkeldurr (Counter + Dynamic Punch)

If weather boosts Fighting or Ground attacks (Cloudy or Sunny weather), adjust your team to prioritize boosted counters to maximize DPS.

👥 Raid Difficulty & Trainers Needed

Due to Mega Aggron’s high defense, it is generally more difficult than other Mega raids. Optimal team composition and coordination are crucial.

2 Trainers: Possible with high-level Fighting Pokémon
3 Trainers: Comfortable clear
4–5 Trainers: Easy win
6+ Trainers: Very safe

🧠 Raid Strategy & Advanced Tips

1. Stack Fighting-Type Attackers

Because of the double weakness, stacking strong Fighting-type Pokémon is the fastest strategy. Even lower-level Fighting Pokémon can perform well, but high-level counters make the raid much easier.

2. Watch for Steel-Type Charged Moves

Mega Aggron can use Steel-type moves like Heavy Slam, which deal heavy damage to Fire or Water counters. Prioritize Fighting-type Pokémon for both offense and survivability.

3. Coordinate Mega Evolutions

Only one Mega Evolution boost is needed at a time. Coordinate with your raid group so that a Mega Fighting Pokémon is active for maximum team-wide DPS.

Mega Aggron’s Steel typing means its greatest vulnerabilities are Fighting, Ground, and Water attacks. While its defenses are very high, choosing Pokémon that take advantage of these weaknesses significantly speeds up the battle. Pokémon like Machamp, Conkeldurr, and Lucario bring powerful Fighting-type charged moves that hit super-effectively, especially when boosted by favorable weather.

Weather conditions play a crucial role in this raid. In Cloudy weather, Fighting-type attacks are boosted, which increases your team’s overall DPS. During Rainy weather, Water-type counters such as Swampert and Feraligatr see improved performance, which can help balance damage and survivability. Conversely, Clear or Sunny weather may slightly favor Rock-type moves from Mega Aggron, so building counters that resist Rock attacks helps maintain your team’s endurance.

Dodging heavy charged moves like Iron Head or Rock Slide can buy your team extra seconds and reduce unnecessary KO’s. Prioritize deploying your strongest counters early, and if you’re battling with a raid group, coordinate switch-ins so that high-damage Pokémon are not knocked out too quickly by powerful charged moves.

If using Mega Evolutions, Mega Lucario and Mega Charizard X provide strong offensive support against Mega Aggron’s bulk, especially in small lobbies or solo attempts. These Mega Pokémon empower allied attackers and leverage type advantage to create faster clear times.

🌦️ Weather Boost

Weather conditions strongly influence Mega Aggron raids:

☀️ Sunny Weather

boosts Fire and Ground attackers.

☁️ Cloudy Weather

boosts Fighting-types attackers.

🌨️ Snowy Weather

boosts Steel-types attackers.

🌀 Mega Aggron Moveset

🗡️ Fast Moves

Dragon Tail
Iron Tail
Smack Down

💥 Charged Moves

Stone Edge
Rock Tomb
Thunder
Meteor Beam
Heavy Slam

Pro tip: While it doesn’t hit extremely fast, its high defense and solid damage output can slowly drain your team’s resources if you’re not doing enough DPS.

Mega Aggron’s combination of Rock and Steel moves means many counters take neutral or resisted damage, so focus on durability and dodge charged attacks when possible.

🎮 Is Mega Aggron Good in PvE and PvP?

Is Mega Aggron Good in PvP?

Aggron is not commonly used in PvP leagues because many stronger Steel Pokémon exist.

Is Mega Aggron Good in PvE?

Mega Aggron is not one of the best raid attackers, but it is extremely durable. However, its Mega Evolution provides useful Steel-type attack boosts for raid teams.

✨ Can Mega Aggron Be Shiny in Pokémon GO?

Yes, trainers can encounter a Shiny Aggron after defeating Mega Aggron in a Mega Raid battle. While the Mega Evolution itself cannot be caught, players will encounter the standard Aggron after the raid, which has a chance of being shiny.

Shiny Aggron has a distinctive green and silver appearance compared to the normal gray version. Because shiny Pokémon are rare, many trainers participate in multiple Mega Aggron raids to increase their chances of encountering one.

Mega Raids often have improved shiny encounter rates compared to wild Pokémon, making them a great opportunity for collectors looking to add a shiny Aggron to their Pokémon GO collection.
