The next Community Day has been announced for April 13 from 3:00pm–6:00pm local time in Pokémon GO, and the star of that show is the Dragon-type Bagon, who will appear much more commonly throughout the Community Day event.
During the three-hour event there will be a 3× multiplier for Catch XP, all placed Lures will last for 3 hours, and any Bagon caught during this time have a chance for special, previously unavailable move. Evolving Bagon during this time will retain that move as well. Which move it is has yet to be announced, though.
