In a surprise announcement, Monday morning Niantic revealed that plans to add the Alola Forms of Kanto RegionPokemontoPokemon GOin the coming weeks. The announcement was made via the officialPokemon GOTwitter account, along with a classic “Who’s that Pokemon?” style teaser featuring all of the Alola Forms in shadow. Niantic will provide more details in the near future.

Within the teaser image, virtually all of the knownPokemonwithAlola Formsare accounted for, barring certain evolutions. It’s unclear if Niantic will be holding back some of the forms or if there just wasn’t enough room to fit all the forms in the image. ThePokemonthat are missing include Sandshrew, Ninetales, Persian, Raticate, Golem, Graveller, and Dugtrio. Each of them has a pre-evolution, or in Sandshrew’s case evolution, included in the image, so there’s hopefully nothing to worry about.

All of the Alola FormPokemonare based onPokemonfrom Generation 1 of the franchise, also known asKanto-regionPokemon. SincePokemon GOalready features Kanto-region Pokemon, the addition of Alola Forms makes a lot of sense before jumping into an all new generation ofPokemon. Plus, it’s probably a lot easier for Niantic to add them without a major update.

Speaking of how Niantic plans to add the Alola Forms toPokemon GO, it’s going to be interesting to see what the developer decides. It seems unlikely that Alola Forms will simply be added to the general population ofPokemon, spawning like your average Pidgey or  Ratata. Niantic will assuredly figure out a way to introduce the Alola Forms through special events, perhaps like the Ho-oh distribution orCharmander-family Community Day.

Alola Forms have been hinted at inPokemon GOfor quite a while now. In November 2017, Niantic introduced a free set of male and femaleAlola avatar customization items, leading to plenty of community speculation. It took six months to finally come to fruition, but the community won’t mind the delay too much. At least, it’ll hold players off from asking for Generation 4 for another month or two.

Pokemon GOis available now on iOS and Android devices.
