Niantic has announced the details of the Season of Mischief which will run from Wednesday, September 1st, 2021, at 10:00 a.m. to Wednesday, December 1st, 2021, at 10:00 a.m. local time.

Welcome to the Season of Mischief!

Trainers, The strange events of Pokémon GO Fest 2021 continue in the Season of Mischief! This Season will focus on an adventure featuring Hoopa, the Mischief Pokémon, which you’ll be able to encounter early on in this Season’s Special Research story: Misunderstood Mischief!

When Hoopa summoned Legendary Pokémon to Pokémon GO during Pokémon GO Fest 2021, time and space were distorted. Hoopa has also brought Pokémon originally discovered in the Galar region to Pokémon GO for the first time! Be sure to follow along during the Season to see what else might happen!

The Season of Mischief will run from Wednesday, September 1, 2021, at 10:00 a.m. to Wednesday, December 1, 2021, at 10:00 a.m. local time.

Hoopa is arriving

Beginning September 1, 2021, at 10:00 a.m. local time, you’ll be able to access a season-long Special Research story. Throughout the Season of Mischief, you’ll gain access to different sets of tasks in this Special Research story. For instance, you’ll be able to encounter Confined Hoopa by completing a set of tasks that’ll unlock beginning September 5. Read on to learn more!

Learn Hoopa’s secrets during the Season!

You’ll be able to access parts of this Season’s Special Research story when certain events begin. The Special Research story will focus on discovering more about Hoopa and the strange occurrences happening throughout the Season, so stay tuned to follow along with the story.
