Chespin, Fennekin, and Froakie, the starters from the Kalos region, were added to Pokémon Go in 2020 and are due for the Community Day spotlight.
Pokémon Go’s next season, the successor to the Season of Heritage, has not been announced, and its theme may offer some clues about future Community Days when it is. The game’s most recent Community Day, for February 2022, featured Hoppip.
Of course, there are plenty of other options, like Oddish, Wailmer, and Noibat, who could use a little love.
Deino, the elusive Dragon-type Pokémon, is also an oft-requested option, and it might be time for Niantic to let some fans finally get their first (or best) Hydreigon.
