The Event

  • Ghost Types will appear in the wild, in raids, and will hatch from eggs more frequently
  • Sableye dressed as Litwick will be available in the wild and eggs
  • Gengar will appear in raids with a special Mega Banette costume. Note that Mega Banette has not been announced for this event, we simply have Gengar dressing up as it.
  • Spiritomb will be available via the latest Halloween Special Research line, "A Spooky Message Unmasked", and will also be available via Field Research. It will also be available in shiny forme for the first time!
  • Galarian Yamask will be available for the first time, and current datamine information suggests that it will indeed be able to evolve into Runerigus!
  • Darkrai is coming back to raids! Expect our raid guides to be updated in the coming days!
  • Mega Gengar is joining Mega Raids, and if you managed to complete the Mega Buddy Challenge earlier this year, you will be granted access to a special research line that will grant Mega Gengar Energy!
  • Themed Research Tasks will be available
  • New Halloween Avatar Items will be available 
  • Special boxes will be available in the shop
  • Snapshots will give special encounters
  • 2x Catch and Transfer Candy

Special Note on Costumed Gengar and Sableye

While it's likely that these Pokemon will be able to Mega Evolve in a manner similar to Sunglasses Blastoise, it's probably best to wait for confirmation before raising either of them.

Alolan Marowak Raid Day: October 31

Start Time End Time
11:00 a.m. 5:00 p.m.

Another less than expected event, on Halloween day we're getting an Alolan Marowak Raid Day. This Ghost/Fire Type Pokemon was slated to have a raid day last year around this time and was stated to be able to learn its Ghost Type signature attack, Shadow Bone, as a part of the event. However, this fell through and we currently have no word on Shadow Bone this year.

worth noting here is the fact that Alolan Marowak has been down-graded to a three star raid boss, meaning it can be reliably soloed. This is especially true with Mega Gengar's debut and Darkrai's return!
