Pokémon GO has quietly added a surprise 10th anniversary reward that gives players a Mewtwo with a unique background and 100% stats, along with a Master Ball. The offer arrived just hours before the story was published and can be claimed until September 6.
That timing is why players are searching for Mewtwo 10th Anniversary Pokémon GO now: there is a new reward on the table, and it is unusual enough to stop the game’s economy in its tracks. Scopely Explore described the freebies as a belated addition to the anniversary celebration and framed them as a way to mark the milestone with players everywhere. In the game’s own words, it said it was excited to share the special reward with Trainers everywhere and to celebrate the journey of the past 10 years.
For players, the headline prizes are hard to ignore. A perfect-stat Mewtwo is one of the most coveted catches in the game, and the Master Ball has not been broadly available since it was last sold as a premium purchase priced at $7.99. Tom Phillips wrote that the offer can be claimed by all players with ease, which makes the giveaway feel even bigger than a routine anniversary bonus.
Still, not everyone is treating it as simple generosity. Some fans are welcoming the reward, but others see it as arriving after they spent dozens of hours and huge amounts of money chasing a perfect Mewtwo of their own. The friction runs deeper because players who attended the controversial New York event last month were not guaranteed a 100% stat Mewtwo, even though that event had already handed out a perfect creature to attendees. The surprise freebies are widely being read as an apology for that backlash, and the Times Square background from the event is expected to return later.
There is also one piece of uncertainty the game has not fully spelled out: some fans received a Shiny 100% Mewtwo, but it is not clear how Pokémon GO will sort that surprise reward for everyone else. For now, the answer that matters is simpler. If you want the Mewtwo, the Master Ball, or both, the window is open now, and it closes on September 6.
