If you want a short, spooky GO Battle League window in late October, the pokemon go mega halloween cup is the one to plan around. It is a limited-time cup, not a wild spawning event, and it rewards careful team building more than raw power.

What Is the Pokemon Go Mega Halloween Cup?
The pokemon go mega halloween cup is the full name used by players for the Mega Halloween Cup: Great League Edition in Pokemon GO. It is part of the GO Battle League season called Twilight Trails, which runs from September 8, 2026, to December 1, 2026.
In simple terms, this is a restricted Great League cup. Every Pokemon must stay at or below 1,500 CP, and every Pokemon must have at least one of five allowed types. Mega-Evolved Pokemon are eligible in this edition, which is the key twist that sets it apart from a standard Halloween Cup format.
Pokemon Go Mega Halloween Cup Dates and US Times
The pokemon go mega halloween cup runs from October 27, 2026, to November 3, 2026. Niantic lists GO Battle League rotations as beginning and ending at 1:00 p.m. PDT (GMT -7) on the dates shown in its Twilight Trails schedule.
US clocks change during this cup window, because daylight saving time ends in the United States on November 1, 2026. That is why guides list the opening time as 8:00 p.m. GMT on October 27 and the closing time as 9:00 p.m. GMT on November 3.

| Cup name | Mega Halloween Cup: Great League Edition |
| Cup dates | October 27, 2026, to November 3, 2026 |
| Rotation switch time | 1:00 p.m. Pacific time |
| Opening time, US | October 27 at 1:00 p.m. PDT / 4:00 p.m. EDT |

| Mega-Evolved Pokemon | Eligible, subject to CP and typing rules |

Do not confuse this rotation time with the wider Halloween event start time. Many Pokemon GO events start at 10:00 a.m. local time, but GO Battle League rotations use the Pacific switch time above.
Official Rules at a Glance
Niantic’s official Twilight Trails page lists three rules for the Mega Halloween Cup: Great League Edition. Those three rules are the safest starting point for any team, because they come directly from the official schedule.
- Pokemon must be at or below 1,500 CP to enter.
- Mega-Evolved Pokemon are eligible.
- Only Bug-, Poison-, Ghost-, Dark-, and Fairy-type Pokemon are eligible.
The pokemon go mega halloween cup does not use a separate banned list in the official cup rules checked for this guide. If a Pokemon has two types, only one of those types needs to be on the allowed list. Always confirm your final team on the in-game battle entry screen before you spend Stardust, Candy, or Mega Energy.
How This Cup Differs From Halloween Part 1
The pokemon go mega halloween cup is not the same thing as Halloween 2026 Part 1, even though the two overlap in late October. Part 1 is the wider Halloween event, with its own spawns, costumes, raids, and bonuses, while this cup is a GO Battle League rotation.
Halloween 2026 Part 1 was listed as ending on November 1, 2026, at 10:00 a.m. local time. The pokemon go mega halloween cup keeps running after that point, until November 3 at 1:00 p.m. Pacific time. In Part 1, you catch, raid, and complete event content in the wild, while in this cup you battle other trainers with a restricted team.
Which Types Can Enter the Pokemon Go Mega Halloween Cup?
Only five types can enter the pokemon go mega halloween cup, and that narrow pool shapes the whole meta. The allowed types are Bug, Poison, Ghost, Dark, and Fairy. Every team member must carry at least one of those types, and every team member must stay at or below 1,500 CP.
- Bug types bring fast disruption and useful coverage against Dark and Psychic opponents.
- Poison types bring steady pressure against Fairy opponents and useful bulk in several matchups.
- Ghost types bring strong pressure against Psychic and Ghost opponents, but they must watch for Dark answers.
- Dark types bring valuable resistance to Psychic damage and strong answers to Ghost opponents.
- Fairy types bring powerful answers to Dark opponents and useful bulk in longer battles.
Dual types are especially useful in the pokemon go mega halloween cup. A Fairy and Steel Pokemon, for example, can resist a wide range of attacks while still qualifying through Fairy typing.
Mega Evolution in the Pokemon Go Mega Halloween Cup
Mega Evolution is the headline twist in the pokemon go mega halloween cup, and it is also the area where players need to be most careful. Niantic’s official rules say Mega-Evolved Pokemon are eligible, subject to the CP limit and the allowed types. That means a Mega form must still fit the same 1,500 CP cap and the same five-type pool as a normal Pokemon.
Guides for this cup report that only one Mega-Evolved Pokemon should be used per team. That one-Mega guidance is reported by team guides, not stated in the short official cup rules quoted above, so treat it as a guide rule to verify in game.
There is also a CP point that needs care. Niantic’s Twilight Trails update says that if a Mega-Evolved Pokemon’s CP exceeds a league or cup limit, its level will temporarily adjust during the battle so its CP fits the limit. At the same time, team guides warn that a Mega Sableye over 1,500 CP after Mega Evolution may not work as expected.
Because those two points can read differently, do not spend Mega Energy until the in-game entry screen accepts your exact team. You do not need a Mega Pokemon to compete in the pokemon go mega halloween cup, and a well-built normal team will beat a poorly built Mega team.
Best Teams to Try in the Pokemon Go Mega Halloween Cup
The teams below are recommendations from current team guides for the pokemon go mega halloween cup, not guaranteed wins. No team wins every matchup, because you cannot see your opponent’s team before the battle starts.
- Forretress, Mega Greninja, and Nidoqueen: a guide-recommended trio with bulk, speed, and Ground and Poison coverage.
- Mimikyu, Tinkaton, and Clodsire: a second guide-recommended trio with Ghost and Fairy pressure plus a Poison and Ground closer.
- Tinkaton, Mimikyu, and Clodsire: a similar trio with Tinkaton as the lead, Mimikyu for Ghost and Fairy pressure, and Clodsire saved for Steel and Poison threats.
- Umbreon, Nidoqueen, and Azumarill: a bulkier option with a Dark lead, Poison support against Fairy threats, and Water damage against Ground threats.
- Carbink, Forretress, and Morpeko: a high-bulk option with Rock and Fairy defense, a Steel and Bug switch, and fast Electric and Dark damage.
- Mega Sableye, Clodsire, and Tinkaton: a Mega-led option with Dark and Ghost pressure plus partners that help against Fairy attacks.
The Forretress, Mega Greninja, and Nidoqueen team covers several common threats at once. The Mimikyu, Tinkaton, and Clodsire team works differently, because Mimikyu and Tinkaton apply early pressure while Clodsire gives you a sturdy closer. Carbink, Forretress, and Morpeko is strong on paper, but guides note that Carbink may need substantial Candy XL investment to get close to 1,500 CP.
Best Pokemon and Moves to Aim For
Moves matter as much as team order in the pokemon go mega halloween cup, because the CP cap keeps stats close. A Pokemon with the right Fast and Charged Moves can reach its key attacks sooner and force shields earlier. The moves below are the recommended sets from current team guides for this cup.
| Pokemon | Recommended Fast Move | Recommended Charged Moves |
|---|---|---|
| Tinkaton | Fairy Wind | Gigaton Hammer, Bulldoze |
| Mimikyu | Shadow Claw | Shadow Sneak, Play Rough |
| Clodsire | Poison Sting | Earthquake, Stone Edge |
| Umbreon | Snarl | Dark Pulse, Last Resort |
| Nidoqueen | Mud Slap | Earth Power, Poison Fang |
| Azumarill | Bubble | Ice Beam, Play Rough |
| Carbink | Rock Throw | Rock Slide, Moonblast |
| Forretress | Volt Switch | Sand Tomb, Rock Tomb |
| Morpeko | Thunder Shock | Aura Wheel, Psychic Fangs |
| Mega Sableye | Shadow Claw | Foul Play, Dazzling Gleam |
| Mega Greninja | Water Shuriken | Hydro Cannon, Brutal Swing, Surf |
| Alolan Muk | Poison Jab | Brutal Swing, Ice Punch |
Tinkaton is one of the most forgiving picks in the pokemon go mega halloween cup because its Fairy and Steel typing resists a wide range of attacks. Its only type weaknesses in team guides are Fire and Ground, so keep a safe switch ready for both. Clodsire is another high-value pick, because it can work as a lead, a switch, or a closer.
Mega Greninja is the speed pick in this cup, because Water Shuriken lets it cycle Charged Moves before opponents can settle into a rhythm. Mimikyu deserves a special note, because team guides now state that Mimikyu is allowed in GO Battle League after a June 23, 2026, PvP update. Before you invest resources, note that Umbreon’s Last Resort is a legacy move and Tinkaton’s Gigaton Hammer may need an Elite Charged TM if you missed its April 2026 Community Day window.
Battle Strategy for the Pokemon Go Mega Halloween Cup
Good strategy in the pokemon go mega halloween cup starts before the first Charged Move, with your lead choice. Your lead should be able to handle common openers without burning both shields at once. If your lead loses badly to the most common Ghost, Fairy, and Dark openers, change the lead before you change the whole team.
Keep a safe switch ready for a bad lead, and do not panic-switch into the same weakness. Shield management is just as important as typing in this cup, because saving at least one shield for your closer can turn a close loss into a win.
Watch for debuff moves, because several top picks in the pokemon go mega halloween cup rely on them. Poison Fang can lower Defense, Sand Tomb can lower Defense, and Rock Tomb can lower Attack. Morpeko also needs special care, because guides explain that Aura Wheel switches between Electric and Dark damage as Morpeko changes forms.
Rewards and Stardust Bonus
The headline reward for the pokemon go mega halloween cup week is 4x Stardust from win rewards. Guides and schedule summaries list that bonus for the October 27 to November 3 rotation, which includes this cup and Master League. That bonus applies to win rewards, not to end-of-set rewards.
That 4x Stardust win bonus is separate from Halloween GO Pass catch bonuses. No separate USD price for entering the pokemon go mega halloween cup was listed in the official schedule checked for this guide, so this guide claims no cup entry price. For US players, the practical advice is simple: play your sets during the 4x Stardust window, and do not wait until the last day.
Budget Teams, Mistakes, and Pre-Battle Checklist
You do not need rare or expensive Pokemon to enjoy the pokemon go mega halloween cup, but you do need a team that fits the rules. Budget building is about using Pokemon you already have at or below 1,500 CP, with useful moves, rather than building a brand-new team from scratch.
- Use Pokemon you already have near 1,500 CP instead of powering up a new pick from a low level.
- Check the second Charged Move cost before you unlock it, because some Pokemon are much cheaper to prepare than others.
- Keep a non-Mega team ready, so you can still play if your Mega pick does not fit the CP cap.
- Test the team in a few sets before you spend Elite TMs on legacy moves.
Common mistakes in the pokemon go mega halloween cup are easy to avoid once you know them. The most common mistake is entering with a Pokemon over 1,500 CP, especially after Mega Evolution changes its CP. Another common mistake is assuming the cup starts at 10:00 a.m. local time like many wild events, when GO Battle League rotations switch at 1:00 p.m. Pacific time.
Use this checklist before your first set in the pokemon go mega halloween cup.
- Every team member is at or below 1,500 CP in its battle form.
- Every team member has at least one Bug, Poison, Ghost, Dark, or Fairy type.
- The in-game team builder accepts the full team, including any Mega pick.
- You have a lead, a safe switch, and a closer, not three Pokemon with the same weakness.
- You know which opponent type each team member is meant to answer.
