Pokémon GO published this announcement on 5 Oct 2026. This date identifies the original announcement, not the date an APK was uploaded or this English version was prepared.
Halloween 2026 Part I runs from 27 October 2026 at 10.00 to 1 November 2026 at 10.00, using local time at the place where you play. This is not a single global launch time.
The announced costume variants are: Pikachu wearing a hat and capelet; Zubat wearing a top hat; Sinistea wearing a bow. This list does not guarantee that every player receives each variant; check their in-game requirements.
The schedule follows local time where you play, rather than one global launch time. Check the event screen and distinguish its start and end from separate task or offer deadlines. Costume names are retained so you can match them in the game. This summary does not cover paid bonuses, GO Pass or Shiny chances.
