The fourth generation of Pokémon has started to appear in Pokémon Go, which means there’s a reason to go out into the wild again. Just don’t expect to be able to catch everything currently available from the Sinnoh region without some traveling, because there are already new region-exclusive Pokémon in the wild.
This generation first appeared in the Nintendo DS games Pokémon Diamond, Pearl, and Platinum, and hail from the Hokkaido-influenced Sinnoh region.

As with the third generation, Niantic will be rolling out the new pokémon in waves rather than all at once. The company says it’ll also be announcing new features and expansion to pokémon storage soon. Meanwhile, a handful of generation 3 pokémon — and even one from generation 2 — are yet to be added to the game, mostly because of unique characteristics that Niantic has to figure out how to integrate.
The Silph Road community is crowdsourcing data on which gen-four Pokémon players have found and where, and three stand out as the rarest thus far. Carnivine, Chatot and Pachirisu — inspired by a Venus flytrap, a talking parakeet and a squirrel, respectively — can only be found in specific areas worldwide, according to early reports.

Pokémon Go remains a phenomenally successful mobile game by any other metric, and continues to add features to attract new players and extract more money from the existing base. Recently the game finally enabled trading, while just this week the Android version got support for more advanced AR through Google’s ARCore SDK. Next month Pokémon: Let’s Go will be released for the Nintendo Switch, featuring heavy integration with Pokémon Go.
