Pokémon GO Halloween 2026 Part I Adds Three Costumed Pokémon on October 27

Pokémon GO’s Halloween 2026 Part I runs from October 27 at 10:00 a.m. through November 1 at 10:00 a.m. local time. It debuts Pikachu wearing a hat and capelet, Zubat wearing a top hat, and Sinistea wearing a bow; all three may appear in Shiny form. Tapping spooky surprises in the wild may award event encounters or Rare Candy. Other possible wild encounters include Duskull and Halloween Mischief-costumed Piplup and Drifblim, while One-Star Raids will feature the new costumed Pikachu and Sinistea.

The Halloween 2026 GO Pass and GO Pass Deluxe are available from October 27 at 10:00 a.m. through November 5 at 8:00 p.m. local time. Unlocked rewards expire November 7 at 8:00 p.m. Tier 1 at Rank 10 unlocks 2× Candy for catching Pokémon, or 3× with Deluxe; Tier 2 at Rank 20 unlocks 2× Stardust, or 3× with Deluxe. The listed price for GO Pass Deluxe is US$7.99. A Deluxe upgrade with 10 Ranks costs US$9.99 and grants enough GO Points to reach Rank 11.

Part I is the first half of this year’s two-part Halloween event. The announced Part II runs November 1–5, with Shiny Greavard’s in-game debut and the first opportunity to raise Mega Sableye to Super Max Mega Level. The two event windows meet on November 1, while the GO Pass reward-claim deadline extends beyond Part II.
