Season of Mischief
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!

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.
