Research 
-
Continue to follow the Season of Mischief storyline focused on the Mythical Pokémon Hoopa!
-
If you complete this Season’s Special Research story, you’ll gain access to a special event at the end of the Season that might have something to do with Hoopa!
-
A new part of the Season-long Special Research will unlock during each part of the Pokémon GO Halloween Mischief event. With more Psychic-, Ghost-, and Dark-type Pokémon appearing in the wild—along with new ones being discovered for the first time ever in Pokémon GO—this is the perfect opportunity to learn more about the Mischief Pokémon!
-
-
A Special Research story—What Lies beneath the Mask?—will be available!
- Ghost-type Pokémon are appearing more often than usual, and Professor Willow has tasked you with learning more about them. Notably, Yamask has started appearing in the wild, prompting his interest in learning more about Ghost-type Pokémon related to masks. What can we learn about these Pokémon—and what can we learn about ourselves in the process?
-
Timed Research will be available with tasks focused on participating in the Halloween Cup in the GO Battle League.
