Content overview: “Pokémon GO Halloween 2026: Three New Costumed Pokémon, Shiny Encounters, and Rewards Start”. Niantic’s Pokémon GO is set to launch its Halloween 2026 event on October 27, introducing three new costumed Pokémon to the popular mobile game. While the specific Pokémon and costume designs have not been detailed in the announcement, the addition of new variants is a key draw for collectors and competitive players alike. Halloween events have historically boosted player engagement, and this year’s lineup aims to continue that trend with limited-time content.
Niantic has scheduled the event to run through early November, though exact end dates and bonus mechanics are expected to be revealed closer to launch. For trainers, the event offers a chance to expand their Pokédex with rare costumed forms and hunt for elusive Shiny versions. As with previous years, expect increased spawn rates for Ghost- and Dark-type Pokémon, themed Field Research tasks, and possibly special Raid battles. The full version stays on the original page, which this listing opens directly.
