Halloween 2026 Part II

For the first time in Pokémon GO, you’ll be able to encounter Shiny Greavard — if you’re lucky!

You may encounter Greavard in the wild or when you complete GO Pass and Field Research tasks.

Greavard evolves into Houndstone; its Shiny form is shown here as well.

You may encounter event-themed Pokémon in the wild, including Litwick*, Rowlet wearing a Pokémon Halloween costume*, Greavard*, and more!

You might even encounter Gengar wearing a Spooky Festival costume*!

*If you’re lucky, you may encounter a Shiny one!

The following Pokémon will appear in One-Star Raids.

*If you’re lucky, you may encounter a Shiny one!

Starting with the Halloween 2026 Part II event, you’ll be able to increase Mega Sableye’s Mega Level all the way up to Super Max Level for the first time in Pokémon GO!

As discovered during Mega Finale, Pokémon that are eligible to unlock Super Max Level can learn an additional Charged Attack while they’re Mega Evolved. Sableye will now be able to use an additional Charged Attack, Night Shade+, when it’s Mega Evolved.

• Trainer Battles: 55 power
• Raid Battles: 160 power

The power of this attack will increase with the Pokémon’s Mega Level.

Remember: you must increase a Pokémon’s Mega Level to the third level, Max, before you can increase it to Super Max. Mega Evolving alone won’t be enough — you’ll need to use that Pokémon’s Mega Energy to power it up.

Event-themed Field Research tasks will be available — complete them to earn encounters with event-themed Pokémon, including Greavard.

The GO Pass: Halloween 2026 spans both parts of the event — from Tuesday, October 27, at 10:00 a.m. to Thursday, November 5, 2026, at 8:00 p.m. local time.
