The next Pokémon Go Community Day event is Sunday, Oct. 21. It will feature Beldum, the Steel and Psychic-type Pokémon from the Hoenn Region.

Beldum is one of the rarer Pokémon in Pokémon Go , so this latest Community Day event is the perfect time for trainers to finally catch one, and snag enough candy to evolve it (it has two forms: Metang and Metagross). Like with past Community Days, Beldum will appear more frequently and there are also other in-game perks for Pokémon Go players who participate.
