Hit-making pop-rapper Post Malone will link up with the team at Pokémon for a concert livestream in honor of the global media franchise’s 25th anniversary on “Pokémon Day,” Saturday, February 27th, at 7:00 p.m. ET. The Post Malone virtual concert will stream for free via the Pokémon YouTube and Twitch pages.

The Nintendo-owned juggernaut unveiled plans for the event in a tweet on Thursday featuring Post Malone. In it, Posty’s recognizably tattooed mug is digitized for the Pokémon world as he sets out to be the very best, like no one ever was. The caption shared along with the announcement video captures gut reactions to the Mad Libs-like collaboration in a nutshell: “It’s the concert you never saw coming, Trainers.”

On the Pokémon 25 website, event organizers explained the “gotta catch ’em all” mentality behind the peculiar match of the beloved cartoon/video game/multimedia franchise and the famously rowdy “rockstar,” explaining, “This massive online party is an exciting opportunity to unite Pokémon and music fans around the world.”

The announcement also notes that the Post Malone event will kick off a yearlong P25 Music Program. While details on that remain sparse, Katy Perry also confirmed that she will be collaborating with the project throughout the year.

Pokémon has not specifically noted whether or not the performance will be available on GameBoy Color. Watch the announcement video below.
