Harvest Festival Brings Shadow Zekrom Rescue and Shinies to Pokémon GO

From Oct 2–5, 2026, Harvest Festival lets you rescue Shadow Zekrom, chase Giovanni with a Super Rocket Radar via the GO Pass, and encounter event-themed Pokémon (with a chance for Shiny versions). Wild spawns include Koffing, Slugma, Numel, Magmar, and more, with Shiny Shroodle debuting and increased Shiny Slugma odds. You can use a Charged TM to remove Frustration from Shadow Pokémon, and 1-star/3-star Shadow Raids will have wider stat variance. Complete Field Research for Fast/Charged TMs and Mysterious Components. Shadow and Purified Pokémon cannot fuse, and GO Pass rewards run until Oct 7, 2026. Be mindful of your surroundings while playing.
