Unlock Eternatus by progressing the free GO Pass: Max Finale during the Pokémon GO Fest 2025: Max Finale window. The pass activates automatically and includes an Eternatus encounter on its free track. The official event runs August 23–24, 2025, 10:00 a.m.–6:00 p.m. local time, with more Power Spots, a higher Max Particle cap, and no limit on Remote Raids to speed up progression (see the official announcement on Pokémon.com).

Method 1: Unlock via the Free GO Pass: Max Finale

Open Pokémon GO and confirm the free GO Pass: Max Finale is active.

Join raids or start Max Battles to earn GO Pass Points.

Visit Power Spots to collect Max Particles to fund additional Max Battles.

Progress to Rank 60 on the free track to unlock the Eternatus encounter.

Tap the Eternatus reward at Rank 60 and complete the catch before pass rewards expire in late August (local deadlines apply).

Use unlimited Remote Raids during the event weekend if you can’t attend in person to keep ranks moving.

Method 2: Free-to-Play Week Plan (No Coins, Minimal Time)

From Monday through Friday, use your free daily raid pass on a 5-star raid to bank reliable GO Pass Points.

Solo 1–3★ Max Battles during the week to gather Max Particles without needing a large group.

Delay claiming large Max Particle bundles from research until Saturday to take advantage of the increased collection limit during the event.

On Saturday and Sunday (10:00 a.m.–6:00 p.m. local time), spend saved Max Particles on Max Battles your lobby can realistically clear; use unlimited Remote Raids to fill any gaps.

Claim the Rank 60 Eternatus encounter as soon as it unlocks to avoid missing the reward window.

After You Catch Eternatus: Key Facts and Upgrades

Eternatus is designed around Max Battles and the Dynamax system. A few rules and tips will save time and resources as you build it.

You obtain Eternatus from the free GO Pass: Max Finale at Rank 60; earlier pass ranks feature other bonus encounters starting around Rank 15.
Eternatus cannot be traded.
Eternatus cannot be sent to Pokémon HOME.
Eternatus retains Dynamax Cannon and it can’t be forgotten.
Eternatus does not transform into Eternatus (Eternamax) in Max Battles or the max phase.
Eternamax Eternatus appears only as a Max Battle boss; you don’t catch it after the fight, but you do earn Eternatus Candy and Candy XL.

Dynamax Cannon Adventure Effect

Dynamax Cannon is an Adventure Effect that boosts the power level of Max Moves for 10 minutes. Locked Max Moves become Level 1, while Level 3 moves increase to Level 4, which significantly raises output in Max Battles.

Activate Dynamax Cannon for 10 minutes using 5,000 Stardust and 30 Eternatus Candy.

Extend the timer in 10-minute increments up to 24 hours if you plan a long session (cost scales with time).

Avoid running other Adventure Effects at the same time; only one can be active.

Power-Up Planning

Eternatus is extremely resource-intensive to max out. Expect a long-term project even with active play.

Rough requirement to Level 50 is on the order of 8,900 Eternatus Candy and 8,900 Eternatus Candy XL.
Use event Max Battles to stockpile Candy and XL Candy; the weekend offers more Power Spots and a higher Max Particle cap for sustained runs.
Target realistic benchmarks (e.g., mid-30s) first, then work toward 40 and beyond as Candy XL accumulates.

Event Timing and Practical Tips

GO Pass: Max Finale auto-unlocks around August 18, 10:00 a.m. local time. Progress through the week, then surge on August 23–24, 10:00 a.m.–6:00 p.m. local time.
Claim all pass rewards promptly once you finish; late-August local deadlines apply.
If large-group Eternamax lobbies are scarce, prioritize lower-tier Max Battles and 5-star raids to keep ranks climbing steadily.

Focus on daily raids, farm Max Particles, and push hard during the weekend window—hitting Rank 60 on the free track will secure your Eternatus without spending coins.
