Mewtwo Returns in New Pokémon GO 10th Anniversary Event

Niantic has launched a new 10th Anniversary Timed Research event in Pokémon GO that guarantees players an encounter with the fan-favorite Pokémon Mewtwo, the Pokémon GO team announced. The event is available from Wednesday, August 12, 2026, at 4:00 p.m. PDT to Sunday, September 6, 2026, at 11:59 p.m. local time, continuing the game's milestone celebrations.

The mobile game officially celebrated its tenth anniversary in July 2026, marking a decade since its July 6, 2016 launch had players mapping out local parks. For players who have stuck around since the days when the servers collapsed every twenty minutes, the reward is a guaranteed meeting with one of the franchise's most recognizable legends. To secure the encounter, players must capture and power up ten different Pokémon.
