It’s been rumored since before the game even came out, and now, a year into release and days before Pokémon GO Fest in Chicago, Niantic has finally confirmed that Legendary Pokémon are indeed coming to Pokémon GO, and soon. Fan favorites like Zapdos, Moltres, Articuno, Lugia, Ho-Oh, Celebi, Mew and Mewtwo will start appearing in-game as early as July 23 for players around the world. From the announcement:
As Trainers around the world go out and explore their neighborhoods in search of Pokémon and Raid Battles, they can keep an eye out for unique Legendary Eggs appearing at Gyms. If Trainers and their team are able to successfully defeat a Legendary Raid Boss, they’ll have the opportunity to catch a Legendary Pokémon of their own! While Legendary Pokémon will help them take on the toughest Raid Bosses and Gym Battles, they’re not willing to leave their Trainer’s side, so they can’t be left to defend Gyms.
There’s a bit of a catch, if a small one. Legendary Pokémon will only become available if players attending Pokémon GO Fest manage to defeat the Pokémon that show up there on July 22. It would be hilarious, of course, if the challenge were set up in some way where it was possible for the community at large to fail at unlocking Legendary Pokémon and we all had to, I don’t know, wait for next year or something. Don’t expect that to happen. By all reasonable assumptions, the high-level players in Grant Park on Saturday will be able to handily capture some Legendary birds and unlock them for the rest of the world on the next day.
