Is Mega Aggron good in Pokemon GO?

Situational
Power upStardustCandyXL Candy
Lv 20 → 40 135,000 15

Tier B at rank #20 makes Mega Aggron a useful Rock-type filler rather than an endgame pick. Build one if your Rock bench is thin, but keep the XL Candy for something stronger.

  • Bulk-leaning spread (331 Defense / 172 Stamina) — it stays on the field longer, which suits shielded PvP formats.
  • A second charged move costs 10,000 Dust and 25 Candy, and with 5 charged moves to pick from it is the single biggest PvP upgrade you can buy.
  • Its moves get a damage boost in Partly Cloudy and Snow weather — worth timing raids around.

FAQ

What is the best moveset for Mega Aggron in Pokemon GO?

Mega Aggron's best moveset is Smack Down (fast) with Meteor Beam (charged), worth 14.9 DPS as a Rock-type attacker. Use a Fast TM or Charged TM to reroll onto it.

For PvP, run Metal Sound and Meteor Beam instead — league movesets prioritise energy generation and shield pressure over raw DPS.

What are Mega Aggron's weaknesses in Pokemon GO?

Mega Aggron takes super effective damage from Fighting, Ground, Water-type moves. It is double weak to Fighting, Ground (2.56× damage), so those attackers cut through it fastest. It resists Poison, Flying, Normal, Bug, Dragon, Fairy, Ice, Psychic, Rock, so avoid those types against it.

What is Mega Aggron's max CP in Pokemon GO?

Mega Aggron reaches 4,705 CP at level 50 with XL Candy, or 4,162 CP at level 40. Level 50 needs XL Candy, which only unlocks at Trainer Level 31 and comes from catching, hatching, transferring and walking.

Is Mega Aggron good for PvP in Pokemon GO?

Mega Aggron is ranked #18 (Tier B) in Master League with a 67.34% win rate.

In CP-capped leagues a lower Attack IV lets you reach a higher level under the cap, so the ideal spread for Master League is 15/15/15 rather than a hundo.

Unlocking the second charged move is the highest-value upgrade: it lets Mega Aggron bait shields instead of committing to one attack.

What CP is a 100% IV Mega Aggron?

A perfect 15/15/15 Mega Aggron shows 2,378 CP at level 20 (raid and egg catches) and 2,973 CP at level 25 (weather boosted). Seeing that exact number on the catch screen means it is a hundo — favourite it before you transfer anything.

How do you get Mega Aggron in Pokemon GO?

Evolve it from Aggron ( Candy). It is currently a Mega Raids raid boss.

Can Mega Aggron be shiny in Pokemon GO?

Shiny Mega Aggron depends on whether Niantic has released the form. Check the events page for Community Days and event weekends, which is when shiny rates are boosted.
