Pokémon Go’s region-exclusive Pokémon coming worldwide — for a limited time

Pokémon Go’s next event is a big one for anyone in need of hard-to-find Pokémon. Called the Ultra Bonus Event, the campaign will send four different legendary Pokémon back into Raid Battles, including one for the first time.

But perhaps more exciting is that Niantic will also make several Pokémon almost impossible to obtain in the West available as part of the event. Four different regional exclusives can be found in Pokémon Eggs through the end of the month, which is a big deal for anyone without the means to travel.

First off, the legendaries: Articuno, Zapdos and Moltres will be at gyms worldwide for legendary Raid Battles, including their special shiny versions. They’ll be hanging out from Sept. 13 at 4 p.m. EDT, when the Ultra Bonus Event kicks off, until Sept. 20.

Once they leave, an even rarer Pokémon will take their place: Mewtwo will take over from Sept. 20 at 4 p.m. EDT and will be available in Raid Battles all the way until Oct. 23 at 4 p.m. EDT. This is huge news for people who have been neglected by the controversial EX Raid invitation system thus far; until now, Mewtwo could only be caught through these exclusive battles, which players could only get into through (seemingly random) special selection.

Last are the four regional exclusives that will be hidden in 7-kilometer Eggs until Oct. 8. Those are Farfetch’d, Kangaskhan, Mr. Mime and Tauros; they’re generally exclusive to Asia, Oceania, Europe and North America, respectively. Farfetch’d has traveled West before, but this will be the first chance that players outside of European and Oceanic countries will be able to hatch Kangaskhan and Mr. Mime.

The Ultra Bonus Event is pitched as a special end-of-season promo following the various summer Pokémon Go events Niantic held this year. Based on what’s offered here, this may be the most exciting of all.

Update: Niantic has extended the availability of Farfetch’d, Kangaskhan, Mr. Mime and Tauros for an extra week. Players will have the chance to hatch them from 7-kilometer eggs until Oct. 8; we’ve updated the date above.
