Pokemon GO is gearing up for its highly anticipated Delightful Days season, set to run from June 3 to September 2, 2025. This summer-themed season promises exciting new content, including the potential debut of a fan-favorite Gen 5 Pokemon and special anniversary celebrations. As the Might and Mastery season comes to a close, trainers worldwide are eagerly anticipating what Niantic has in store.

The recent teaser trailer for Delightful Days has sparked considerable excitement among the Pokemon GO community. The brief but impactful video hints at several key features coming to the game, including Party Hat Bulbasaur's possible evolution and the long-awaited debut of Hisuian Lilligant. These additions would mark significant milestones in the game's ongoing development and content expansion.

One of the most intriguing aspects of the trailer is the appearance of mysterious pink-aura shadows, which many speculate could represent Dynamax versions of Latios and Latias. This theory gains credibility from Niantic's recent pattern of introducing Dynamax Legendaries to the game. If true, these powerful Pokemon would add an exciting new dimension to battles and raids during the summer season.

The Delightful Days season coincides with Pokemon GO's ninth anniversary in July, suggesting special anniversary events are likely. The trailer's subtle references to party hat-wearing starter Pokemon (Bulbasaur, Squirtle, and Wartortle) hint at possible celebratory content. Fans have particularly noted the potential for Party Hat Bulbasaur to finally gain evolution capabilities, a feature long requested by the community.

Adding to the excitement, the trailer briefly shows Copacabana Beach, potentially teasing an upcoming Rio de Janeiro-themed event. This international flavor would complement the global nature of Pokemon GO Fest 2025, which will feature in-person events in Osaka, Paris, and Jersey City, plus a worldwide event on June 28.

As the Might and Mastery season concludes, players can look forward to Gigantamax Rillaboom making its debut on May 31. This sets the stage for what promises to be an action-packed transition into the Delightful Days season, with Community Day events already scheduled for June 21 and beyond.

With its combination of new Pokemon introductions, potential Dynamax additions, anniversary celebrations, and international events, the Delightful Days season appears poised to deliver one of Pokemon GO's most exciting content periods to date. Trainers around the world should prepare for a summer filled with adventure, discovery, and plenty of Pokemon-catching opportunities.
