Pokemon GO' Season 20 has been officially revealed. Called Tales of Transformation, the upcoming update promises a fairly decent variety of themed content, including new Gigantamax debuts, more Pokemon GO Mega Evolutions, and a major focus on Keldeo.
November 2025 will mark the fifth anniversary of Pokemon GO seasons, originally introduced as part of Niantic's efforts to overhaul its game-making practices, smoothing out its content delivery pipeline with the goal of reducing developer stress and making major updates more predictable in their timing. The quarterly structure allowed the company to prioritize fewer—but noticeably more content-packed—updates, introduced multi-month character arcs, and helped establish competitive play as a core part of Pokemon GO's identity, prompting Niantic to reorganize its GO Battle League calendar in order to have it sync up with the overarching seasons better.
After teasing the advent of Pokemon GO's Tales of Transformation era on several occasions, Niantic has at last formally announced the game's next season earlier today, August 26. Headlining the upcoming content update is a special research storyline focused on Keldeo, the Gen 5 Colt Pokemon whose Resolute form will finally be debuting in Pokemon GO during the new season.
Though Keldeo's been part...
