How to get Mega Chesnaught in Pokémon GO is now straightforward during Pokémon GO Fest 2026: Mega Finale, but you need to choose Chespin during the event’s branching Timed Research if you want the free GO Pass route to its Mega Energy. The Chespin path provides enough Chesnaught Mega Energy to Mega Evolve Chesnaught for the first time, alongside Chespin encounters, Candy and Special Background rewards.
Mega Chesnaught makes its Pokémon GO debut as part of the Mega Finale celebrations. It is a Grass and Fighting-type Mega Evolution and can use the new additional Charged Attack Seed Bomb+ while Mega Evolved.


How to Get Mega Chesnaught in Pokémon GO
The main how to get Mega Chesnaught in Pokémon GO method during Mega Finale is through the Chespin path of GO Pass: Mega Finale.
To begin, complete the branching Mega Finale Timed Research and choose Chespin rather than Fennekin or Froakie.
That unlocks the Chespin version of GO Pass: Mega Finale. Progressing through the free track provides Chespin-focused rewards and enough Chesnaught Mega Energy to perform the first Mega Evolution.
| Step | What to do |
|---|---|
| 1 | Complete the Mega Finale branching Timed Research |
| 2 | Choose Chespin |
| 3 | Unlock the Chespin GO Pass: Mega Finale path |
| 4 | Earn GO Points and progress through the pass |
| 5 | Collect Chesnaught Mega Energy |
| 6 | Evolve Chespin into Chesnaught if needed |
| 7 | Mega Evolve Chesnaught |
The free GO Pass contains enough Mega Energy to complete that first Mega Evolution without requiring the Deluxe upgrade.
How Much Mega Energy Does Mega Chesnaught Need?
Mega Chesnaught requires 300 Chesnaught Mega Energy for its first Mega Evolution.
After Mega Evolving a particular Chesnaught for the first time, subsequent Mega Evolutions can become cheaper or eventually free after its Mega Evolution rest period.
This makes the free GO Pass particularly useful for anyone searching how to get Mega Chesnaught in Pokémon GO, because Pokémon GO specifically confirms that the free track contains enough Mega Energy to Mega Evolve your chosen partner once.
GO Pass Deluxe provides additional Mega Energy for players who want to increase Mega Chesnaught’s Mega Level more quickly.

How to Choose the Mega Chesnaught Path
The Chespin path begins with Mega Finale Timed Research.
Trainers are asked to choose between:
| Choice | Mega Evolution path |
|---|---|
| Chespin | Mega Chesnaught |
| Fennekin | Mega Delphox |
| Froakie | Mega Greninja |
If your priority is how to get Mega Chesnaught in Pokémon GO, choose Chespin.
Your selection affects the rewards received from GO Pass: Mega Finale, including Mega Energy and Special Background encounters.
Our Chespin vs Fennekin vs Froakie Pokémon GO guide compares all three paths if you have not made the choice yet.
How to Evolve Chespin Into Chesnaught
You need a Chesnaught before you can Mega Evolve it.
The Chespin evolution line requires:
| Evolution | Cost |
|---|---|
| Chespin into Quilladin | 25 Chespin Candy |
| Quilladin into Chesnaught | 100 Chespin Candy |
| Chesnaught into Mega Chesnaught | 300 Chesnaught Mega Energy for the first Mega Evolution |
Chespin appears throughout all eight rotating habitats during Pokémon GO Fest 2026: Mega Finale, so Trainers can continue catching Chespin and collecting Candy regardless of which habitat is active.
The GO Pass also provides Chespin encounters and Candy for players following the Chespin path.
Does Mega Chesnaught Have a New Move?
Yes. Mega Chesnaught can use Seed Bomb+ while Mega Evolved.
Seed Bomb+ is one of the new additional Charged Attacks introduced for the Kalos first partner Mega Evolutions during Mega Finale.
The attack belongs to Mega Chesnaught while it is Mega Evolved rather than permanently replacing Chesnaught’s ordinary moveset.
Pokémon GO has also confirmed that the strength of these additional Mega Charged Attacks can increase as a Pokémon’s Mega Level rises.
That gives Trainers another reason to continue progressing Mega Chesnaught after unlocking it rather than treating the first Mega Evolution as the end of the process.
Can Mega Chesnaught Reach Super Max Level?
Mega Chesnaught is part of Pokémon GO’s expanded Mega Evolution system.
The free GO Pass provides enough Mega Energy for the first Mega Evolution, while GO Pass Deluxe provides substantially more Mega Energy for Trainers interested in raising the Mega Level further.
To reach Super Max Level, a Pokémon must first reach the third Mega Level, Max.
Progress can be made by repeatedly Mega Evolving the Pokémon and by spending Mega Energy to increase its Mega Level.
For players primarily interested in simply learning how to get Mega Chesnaught in Pokémon GO, the free path is enough to unlock it. Super Max progression is a much longer-term goal.

Can You Get More Chesnaught Mega Energy?
Yes. Mega Energy is not limited permanently to the initial GO Pass reward.
Pokémon GO confirms that Mega Energy can generally be obtained by defeating Mega-Evolved Pokémon in Mega Raids. Once you have previously Mega Evolved a Pokémon from an evolutionary line, you can also occasionally earn that Pokémon’s Mega Energy by walking an eligible Pokémon from the line as your Buddy.
This becomes useful after the event if you want to continue working on Mega Chesnaught’s progression.
Is Mega Chesnaught Grass or Fighting Type?
Mega Chesnaught is Grass and Fighting-type.
That means Mega Chesnaught can provide Mega-related bonuses associated with both types while active.
Its dual typing also distinguishes it clearly from the other two new Mega Finale starters:
| Mega Evolution | Typing |
|---|---|
| Mega Chesnaught | Grass/Fighting |
| Mega Delphox | Fire/Psychic |
| Mega Greninja | Water/Dark |
Which one is most useful will therefore depend partly on which typings and Mega bonuses are currently missing from your collection.
Can You Get Mega Chesnaught Without GO Pass Deluxe?
Yes. You do not need GO Pass Deluxe to get Mega Chesnaught.
The standard free GO Pass: Mega Finale contains enough Mega Energy to Mega Evolve your chosen Pokémon once.
The paid Deluxe upgrade offers additional progression, but it is not required simply to unlock Mega Chesnaught.
That makes choosing Chespin the important part of how to get Mega Chesnaught in Pokémon GO during Mega Finale.
When Is Mega Chesnaught Available in Pokémon GO?
Mega Chesnaught debuts as part of the wider Pokémon GO Fest 2026: Mega Finale experience.
GO Pass: Mega Finale became available on August 31, 2026 at 10:00 a.m. local time, while the main Mega Finale weekend runs on September 5 and September 6 from 10:00 a.m. to 6:00 p.m. local time.
Trainers can begin the Chespin path before the main weekend by completing the branching Timed Research and progressing through the event GO Pass.
Is Mega Chesnaught Worth Getting?
Even if Mega Chesnaught is not your first choice for every raid, the Mega Finale event makes it particularly easy to unlock because the free Chespin GO Pass path supplies the Mega Energy needed for the first Mega Evolution.
Mega Chesnaught also introduces Seed Bomb+ and provides Grass and Fighting-type Mega coverage.
For anyone wondering how to get Mega Chesnaught in Pokémon GO, the most important step is therefore simple: choose Chespin in Mega Finale Timed Research, progress through GO Pass: Mega Finale, collect the required Mega Energy and Mega Evolve your Chesnaught.
If you chose Fennekin or Froakie instead, your GO Pass Mega Energy rewards will focus on Mega Delphox or Mega Greninja rather than Mega Chesnaught.
