Pokémon 25th Anniversary

The Pokémon 25th anniversary (ポケモン 25周年), officially branded as Pokémon25, was a celebration held throughout 2021 in commemoration of the twenty-fifth anniversary of the Pokémon franchise, which began with the original Japanese release of Pocket Monsters Red and Green for the Game Boy on February 27, 1996. The franchise was celebrated through various media of the franchise including video games, the anime, the manga, toys, clothing, music and events.

The anniversary saw the announcements of Pokémon Brilliant Diamond and Shining Pearl, which both released on November 19, 2021, and Pokémon Legends: Arceus, which released on January 28, 2022. They are remakes and a prequel, respectively, of the 2006 games Pokemon Diamond and Pearl on the Nintendo Switch.
