Pokémon GO Halloween Mischief 2021 Scares Up Some Fun

Battle fiercely in the GO Battle League’s Halloween Cup, enjoy the haunting music of Lavender Town, catch several Pokémon making their Pokémon GO debuts, and more.

Treat yourself to a spooky Halloween experience with a Pokémon GO event that'll allow you to expand your Pokédex and double your Candy rewards while listening to the haunting notes of Lavender Town. The Pokémon GO Halloween Mischief 2021 event runs from Friday, October 15, 2021, at 10:00 a.m. to Sunday, October 31, 2021, at 8:00 p.m. local time. This event will be divided into two parts, with plenty of featured Pokémon to catch, research to complete, and adventures to be had across both parts.

You can expand your Pokédex with the Pokémon GO debut of Galarian Slowking, Phantump, Trevenant, Pumpkaboo, and Gourgeist. To obtain a Galarian Slowking, set a Galarian Slowpoke as your buddy and catch 30 Psychic-type Pokémon. It's the perfect opportunity to evolve Galarian Slowpoke into Galarian Slowking, because Part 1 of this seasonal spooktacular is all about Poison and Psychic types. Galarian Slowking will also be available after the Halloween Mischief 2021 event has concluded.

All of the mischief and mayhem will play out with the haunting sound of Lavender Town's iconic music in the background, so don't forget to turn the volume up during this event.

Here are some activities you can enjoy throughout the entire event:

  • Battle like a fiend in the Halloween Cup! Timed Research based on Halloween Cup battles will bring sweet rewards.

  • Delve deep into the psyches of Ghost-type Pokémon with a Special Research story: What Lies beneath the Mask?

  • Trick or treat yourself with Candy-focused, event-long bonuses.

  • Catch costumed Pokémon, including Halloween Mischief Pikachu, Halloween Mischief Piplup, and Halloween Mischief Drifblim.

  • Move one step closer toward catching the elusive Hoopa with the next part of the Season of Mischief's ongoing Misunderstood Mischief Special Research story.
