How to get Mega Greninja in Pokémon GO starts with choosing Froakie during the Pokémon GO Fest 2026: Mega Finale branching Timed Research. The Froakie choice unlocks a dedicated GO Pass: Mega Finale path containing Froakie encounters, Candy and enough Mega Greninja Energy to complete Greninja’s first Mega Evolution without buying GO Pass Deluxe.
Mega Greninja makes its Pokémon GO debut during Mega Finale as a Water and Dark-type Mega Evolution. It also gains the new additional Charged Attack Surf+ while Mega Evolved, giving Greninja an extremely strong Water-type raid moveset alongside Water Shuriken.
How to Get Mega Greninja in Pokémon GO During Mega Finale
The simplest how to get Mega Greninja in Pokémon GO method is to select Froakie when completing the Mega Finale branching Timed Research.
Your choice determines which version of GO Pass: Mega Finale you receive.
| Step | What to do |
|---|---|
| 1 | Complete the Mega Finale branching Timed Research |
| 2 | Choose Froakie |
| 3 | Unlock the Froakie GO Pass: Mega Finale path |
| 4 | Complete GO Pass tasks and earn GO Points |
| 5 | Claim Mega Greninja Energy |
| 6 | Evolve Froakie into Greninja if needed |
| 7 | Mega Evolve Greninja |
The free GO Pass includes enough Mega Energy to Mega Evolve your chosen Kalos first partner once.
That means Trainers following the Froakie route can unlock Mega Greninja without purchasing GO Pass Deluxe.
How Much Mega Energy Does Mega Greninja Need?
Knowing the Mega Energy requirement is important when working out how to get Mega Greninja in Pokémon GO.
Mega Greninja requires 300 Mega Greninja Energy for its first Mega Evolution.
| Mega Evolution | Initial cost |
|---|---|
| Mega Greninja | 300 Mega Energy |
After Mega Evolving a particular Greninja for the first time, the normal Mega Evolution rest and reduced-cost system applies. Mega Greninja can subsequently Mega Evolve for 60 Mega Energy immediately, with that cost decreasing as its rest timer progresses.
The Froakie GO Pass path provides enough Mega Greninja Energy to cover the initial 300 Mega Energy requirement.
Choose Froakie to Get Mega Greninja in Pokémon GO
If how to get Mega Greninja in Pokémon GO is your main goal during Mega Finale, choose Froakie rather than Chespin or Fennekin.
The three routes lead to different Mega Evolution progression:
| Mega Finale choice | Mega Evolution |
|---|---|
| Chespin | Mega Chesnaught |
| Fennekin | Mega Delphox |
| Froakie | Mega Greninja |
Choosing Froakie focuses your GO Pass rewards on the Froakie evolutionary line, including partner encounters, Candy and Mega Greninja Energy.
The choice also determines which Special Background Pokémon and path-specific rewards you receive as you progress through GO Pass: Mega Finale.
Our Chespin vs Fennekin vs Froakie Pokémon GO guide compares all three choices before you commit.
How to Evolve Froakie Into Greninja
Before completing how to get Mega Greninja in Pokémon GO, you need a normal Greninja to Mega Evolve.
The full evolution costs are:
| Evolution | Cost |
|---|---|
| Froakie into Frogadier | 25 Froakie Candy |
| Frogadier into Greninja | 100 Froakie Candy |
| Greninja into Mega Greninja | 300 Mega Greninja Energy |
A new Froakie therefore requires 125 Froakie Candy to reach Greninja before Mega Energy becomes relevant.
Froakie appears throughout all eight rotating Pokémon GO Fest 2026: Mega Finale habitats, so Trainers have repeated opportunities to catch it and collect additional Candy during both event days.
Froakie-focused GO Pass rewards provide further encounters and Candy for players following the Mega Greninja path.
What Type Is Mega Greninja in Pokémon GO?
Mega Greninja is a Water and Dark-type Pokémon.
Its weaknesses are Bug, Electric, Fairy, Fighting and Grass-type attacks.
Mega Greninja can provide Mega-related bonuses for both Water and Dark-type Pokémon while active, giving it useful coverage beyond its own raid damage.
The three Mega Finale starter Mega Evolutions have completely different typings:
| Mega Evolution | Typing |
|---|---|
| Mega Chesnaught | Grass/Fighting |
| Mega Delphox | Fire/Psychic |
| Mega Greninja | Water/Dark |
For Trainers deciding how to get Mega Greninja in Pokémon GO versus choosing another Mega Finale path, that Water and Dark combination is one of Greninja’s biggest advantages.
Mega Greninja Gets Surf+
Mega Greninja gains the additional Charged Attack Surf+ while Mega Evolved.
Surf+ is separate from Greninja’s normal Charged Attack options and forms part of Pokémon GO’s expanded Mega Evolution system introduced around Mega Finale.
The strength of additional Charged Attacks can increase as a Pokémon’s Mega Level rises.
For raid battles, Mega Greninja’s recommended Water-type moveset is:
Water Shuriken + Surf+
Current battle analysis places Mega Greninja among the strongest Water-type attackers available in Pokémon GO with this combination.
Is Mega Greninja Good in Pokémon GO?
Yes. There is a practical reason to learn how to get Mega Greninja in Pokémon GO beyond simply completing the Mega Pokédex.
Mega Greninja has a base Attack stat of 299 and reaches a maximum CP of 4,278 at Level 50.
With Water Shuriken and Surf+, current raid analysis ranks Mega Greninja as an S-tier Water-type attacker, making it one of the strongest Water options currently available.
Its Dark typing also allows Mega Greninja to provide useful Dark-type Mega bonuses, although its strongest current raid role is as a Water attacker.
530Can You Get Mega Greninja Without GO Pass Deluxe?
Yes. How to get Mega Greninja in Pokémon GO does not require a paid GO Pass.
Pokémon GO confirms that the free GO Pass: Mega Finale contains enough Mega Energy to Mega Evolve the Kalos partner associated with your chosen path once.
Choose Froakie and the free progression track gives you the Mega Greninja Energy needed for that initial Mega Evolution.
GO Pass Deluxe provides additional rewards and considerably more Mega Energy for Trainers who want to progress Mega Greninja’s Mega Level further.
Can Mega Greninja Reach Super Max Level?
Mega Greninja is eligible for Pokémon GO’s expanded Mega Evolution system.
A Mega Pokémon must first progress through the normal Mega Levels and reach Max Level before it can continue towards Super Max.
Increasing Mega Level normally involves repeated Mega Evolutions, while progression towards Super Max also requires spending Mega Energy.
GO Pass Deluxe provides substantially more Mega Energy than the free route, making it more useful for Trainers who want to push Mega Greninja beyond its initial unlock.
However, Super Max progression is not required simply to complete how to get Mega Greninja in Pokémon GO. The free Froakie path is enough for the first Mega Evolution.
How to Get More Mega Greninja Energy
After unlocking Mega Greninja, there are additional ways to obtain Mega Energy when relevant methods are available.
Pokémon GO confirms that defeating a Mega-Evolved Pokémon in Mega Raids is the main method for collecting large amounts of its Mega Energy.
Once you have previously Mega Evolved a Pokémon from the same evolutionary line, walking an eligible Pokémon from that family as your Buddy can also occasionally reward Mega Energy.
For Mega Greninja specifically, walking a member of the Froakie evolutionary family after unlocking the Mega can provide 15 Mega Energy when the Buddy Mega Energy reward is triggered.

Mega Greninja debuts as part of the Pokémon GO Fest 2026: Mega Finale progression.
