September and October Community Day voting is coming! Will Charmander, Caterpie, Grimer, or Porygon be the winner?

Trainers, Pokémon GO Community Day voting is back! From August 22 to August 23, you’ll be able to vote via Twitter for the Pokémon you’d like featured! The two Pokémon that receive the most votes will go on to be featured during the next two Community Day events, with the Pokémon with the most votes featured in September and the runner-up in October!

Community Day candidates
Your Community Day candidates will be Charmander, Caterpie, Grimer, and Porygon. Here are the exclusive attacks that would be featured for each Pokémon’s Community Day.

• Charmander: Evolve Charmeleon (the evolved form of Charmander) to get Charizard that know the Dragon-type attack Dragon Breath. Dragon Breath gives Charizard a Fast Attack that dishes out damage quickly, and the attack is super effective against Dragon-type Pokémon.
• Caterpie: Evolve Metapod (the evolved form of Caterpie) to get Butterfree that know the Flying-type attack Hurricane. Hurricane offers Butterfree a powerful Flying-type Charged Attack to further strengthen its matchups against Fighting-, Grass-, and Bug-type Pokémon.
• Grimer: Grimer originally discovered in the Kanto region will appear in the wild and hatch from Eggs. Alolan Grimer will appear in Raid Battles. Evolve Grimer or Alolan Grimer to get Muk or Alolan Muk that know the Fire-type attack Fire Punch. Fire Punch would be the first Fire-type attack available for Muk and Alolan Muk, giving them a Charged Attack option that not only charges quickly but also hits Steel-type Pokémon for supereffective damage.
• Porygon: Evolve Porygon2 (the evolved form of Porygon) to get Porygon-Z that know the Normal-type attack Tri Attack. This attack will be new to Pokémon GO and, when used, will have a chance of decreasing the opposing Pokémon’s Attack and Defense.

Featured bonuses and more Community Day details will be announced at a later date.

How to vote
We’ll post a poll on our official English-language Pokémon GO Twitter on Saturday, August 22, 2020, at 6:00 p.m. PDT (GMT −7), and you’ll be able to cast your vote until Sunday, August 23, 2020, at 6:00 p.m. PDT (GMT −7). You’ll have 24 hours to cast one vote for the Pokémon you’d like to see most for either September or October Community Day. The winners will be announced shortly after voting ends. The Pokémon that receives the most votes by the end of the voting period will be the featured Pokémon for September Community Day on Sunday, September 20, 2020. The Pokémon that receives the second-most votes will be featured during October Community Day on Saturday, October 17, 2020.
