Find out more about the legendary Pokémon that are coming to Pokémon GO this Summer in the game’s new trailer.

In celebration of Pokémon GO’s one-year anniversary, Niantic, Inc. and The Pokémon Company International have revealed that Legendary Pokémon will begin to soar into the real world soon. A new Pokémon GO trailer offers a glimpse at the way Trainers will cooperate with one another to discover, battle, and catch elusive and extremely powerful Legendary Pokémon. Once in the wild, Trainers can search for unique Legendary Eggs at Gym locations around the world. Players can team up with friends and other Trainers to join a Legendary Raid Battle to defeat the Legendary Pokémon and earn a chance to catch it.

The battle against the first Legendary Pokémon will require teamwork from millions of Trainers around the world in order to be revealed at Pokémon GO Fest Chicago at Grant Park on July 22. Trainers from all corners of the earth must work together to catch Pokémon during the Pokémon GO Fest Challenge Windows to unlock in-game bonuses and the chance for the first Legendary Pokémon to appear at Pokémon GO Fest. If Trainers successfully defeat the Legendary Pokémon in Chicago, that Pokémon will start appearing in Raid Battles around the world after Pokémon GO Fest.

Pokémon GO is available now on mobile devices.
