The twenty season of Pokémon GO has been officially announced and it’s called Tales of Transformation. This upcoming update is set to deliver a diverse range of themed content, such as the debut of new Gigantamax forms, additional Mega Evolutions in Pokémon GO, and a significant emphasis on Keldeo.
In November 2025, we’ll celebrate the fifth anniversary of Pokémon GO seasons, which were initially launched as part of Niantic’s strategy to revamp their game development approach. The aim was to streamline content delivery, reducing developer strain and ensuring major updates occurred more consistently. This quarterly update system permitted a focus on fewer, yet richer content updates, introduced extended character storylines spanning multiple months, and fostered competitive play as a key element of Pokémon GO’s essence. As a result, Niantic restructured the GO Battle League calendar to align better with these overarching seasons.
Pokemon GO Season 20 To Focus on Keldeo and New Form Mechanics
Following multiple hints about the arrival of the Tales of Transformation era within Pokemon GO, Niantic has officially unveiled the game’s next season today, August 26th. The main attraction for the upcoming content update is a special research storyline centered around Keldeo, the Colt Pokemon from Gen 5, whose Resolute form will be making its debut in Pokemon GO during the new season for the first time.
For almost three years now, Keldeo has been a part of Pokemon GO, yet Niantic’s repeated delays in introducing its Resolute form might have stemmed from an ambition to unveil it at a time when the impact would be most significant. Given that context, a whole season dedicated to the concept of transformation seems like just the right moment for Keldeo to truly shine within Pokemon GO.
As the season advances, participants will gradually unveil fresh phases in the vibrant monster’s upcoming adventure, which centers around transformation. This theme will be further emphasized by the introduction of new Mega evolutions, increased Dynamax and Gigantamax interactions, and a comprehensive focus on various shape-shifting pocket monsters throughout the season. Additionally, Niantic hints at the emergence of additional alternative Pokemon forms during Tales of Transformation.
