The CP you will see on the encounter screen.

IVs Lv 20 CP Lv 25 CP (weather)

15 / 15 / 15 100% 2,437 3,032
Every raid catch has an IV floor of 10/10/10, so the two rows are the real minimum and maximum. If you see 2,437 CP it is a perfect Mega Aggron — throw a Golden Razz Berry.

Raid guide

How the fight goes and what to bring.

Trainer difficulty Mega Aggron goes down with 2 trainers running optimal counters at level 40+. Plan for 4+ if your team is not fully powered up, or 5–6 in a random public lobby.

Do not bring Poison, Flying, Normal damage — Mega Aggron resists it and your lobby will run out of time before it runs out of HP. Everything in the counter list above already hits for super effective damage, so pick the six highest entries you actually own and power up.

In Snow, Partly Cloudy weather the boss hits harder and survives longer, but the catch encounter is level 25 instead of 20 — a harder fight for a better reward. Bring one extra trainer on boosted runs.

On the catch screen, use Golden Razz Berries and aim for Excellent curveball throws; the shiny check happens the moment the encounter loads, so you will know before your first throw.
