Deino and Brutal Swing debut on June Community Day.

What's dark, blue, pointed, and bites? The solution is Deino, 

the Irate Pokémon featured in Pokémon GO's June Community Day event on June 25, 2022.

This Dark- and Dragon-type Pokémon appears more often during the day.

You might even find a green Shiny! If you evolve Zweilous (the Evolution of Deino) during the event or up to two hours after it ends, 

Hydreigon will know the Dark-type Charged Attack Brutal Swing.

June Community Day will include benefits. Incense and Lure Modules will last three hours, 

you'll gain twice as much Candy for catching Pokémon, and Deino Candy XL will be twice as likely.

Plus, friend-to-friend Pokémon trades require half as much Stardust. Between June 24, 2022 at 2:00 p.m. 

and June 25, 2022 at 10:00 a.m., you can make one additional Special Trade.

Working with other Trainers can unlock event perks. 

Getting enough Pokémon near a PokéStop with a Lure Module will attract wild Zweilous.

Field Notes: Deino, a Community Day-exclusive Special Research narrative, 

will cost $1 in-game (or the equivalent pricing tier in your local currency).

Press the Special Research ticket in the in-game shop, then tap the Gift icon to give it to a friend.
