Mega Mewtwo Y 100% IV CP Pokémon GO is one of the biggest searches during Pokémon GO Fest 2026 as Trainers try to work out whether they’ve caught a perfect Mewtwo after defeating a Super Mega Raid. If you’re looking for the Mega Mewtwo Y 100% IV CP Pokémon GO values, here’s everything you need to know.
Mega Mewtwo Y 100% IV CP Pokémon GO
After defeating Mega Mewtwo Y, you’ll encounter a regular Mewtwo rather than the Mega Evolution itself.
That means the hundo CP values are exactly the same as Mega Mewtwo X raids.
| Encounter Type | 100% IV CP |
|---|---|
| Normal Raid (Level 20) | 3492 CP |
| Weather Boosted Raid (Level 25) | 4366 CP |
If your Mewtwo has one of these CP values, you’ve caught a perfect 100% IV Pokémon.
Mega Mewtwo Y CP Range
Every Mega Mewtwo Y raid rewards a Mewtwo encounter within a fixed CP range.
| Encounter | CP Range |
|---|---|
| Normal Raid | 3377–3492 CP |
| Weather Boosted Raid | 4222–4366 CP |
The closer your CP is to the maximum, the better the IVs are likely to be.
Why Are the CP Values the Same?
Although you’re battling Mega Mewtwo Y, the Pokémon you actually catch is a standard Mewtwo.
Because of this, the encounter follows the normal Legendary raid IV system, with fixed CP values for Level 20 and weather-boosted Level 25 encounters.
Can a Hundo Become Mega Mewtwo Y?
Yes.
Once you’ve earned enough Mega Mewtwo Y Energy, any eligible Mewtwo—including a perfect 100% IV Mewtwo—can Mega Evolve into Mega Mewtwo Y.
Many Trainers are specifically hunting for a hundo before investing Mega Energy and Stardust.
