Pokémon GO has celebrated its first anniversary with real-world and in-game summer events, ranging from the Pokémon Go Fest in Chicago in July to the ‘Pikachu Outbreak’ in Yokohama, Japan in August.

“It’s been an incredible first year for Pokémon GO thanks to the passion and dedication from the global Trainer community,” said John Hanke, CEO of Niantic. “As part of the first anniversary, we’ll be giving players around the world the chance to enjoy fun in-game events, engage with friends and other Trainers at real-world events, and much more.”

But far from dropping the Pokéball there, Niantic and The Pokémon Company International have since revealed that the first Legendary Pokémon are now available for Trainers worldwide to discover, battle, and catch in Pokémon GO.

Trainers around the world and the attendees at Pokémon GO Fest in Grant Park, Chicago have worked together to catch millions of Pokémon to unlock a variety of in-game bonuses and welcome the Legendary Pokémon, Lugia and Articuno, to Pokémon GO.

Legendary Raid Battles

Trainers can now team up together to battle Lugia and Articuno in Legendary Raid Battles everywhere starting immediately. Additionally, the Legendary Pokémon Zapdos and Moltres will also soar into Pokémon GO soon.

It seems that the Pokemon Go craze is far from sizzling out, with Niantic rolling out new developments regularly to keep its gamers occupied.
