Save the date — Halloween 2026 Part I takes place from October 27 to October 31, 2026.
Halloween traditionally splits into two back-to-back halves with different featured Pokémon and costumes — but which Pokémon, costumes, bonuses and research belong to this first half has not been revealed yet.
Only the date has been announced so far. The content, bonuses and exact schedule are still unknown — we'll update this page as soon as details are revealed.
