Blizzard and Source Music have revealed the details of the 2024 collaboration between Overwatch 2 and Le Sserafim.

As shared on the official Overwatch blog, the new FEARLESS-themed skins are going to Mercy, Juno, D.Va, Illari, and Ashe. Meanwhile, there will be remixes for the skins from 2023, for Blue Flame Kiriko, D.Va, Sombra, Tracer, and Brigitte. Subsequently, the girls with the new skins are shown performing as Le Sserafim in the announcement trailer, but there’s a big difference this time.
As reported by Chosun Biz, the trailer featured a preview for an upcoming single, So Cynical (Badum). The 2023 collaboration featured their single Perfect Night after it already hit the charts, but this collaboration was timed to also help promote Le Sserafim’s upcoming album, simply titled HOT.
In that sense, this is a much more integrated collaboration, showing fans of both the game and the girl group that they really had good reason to watch out for their return.
So the way Source Music and Blizzard have scheduled this is:
Le Sserafim’s next album HOT released on March 14, 2025. An Overwatch 2 x Le Sserafim collaboration battlefield tour commences from March 18 to 31, 2025. And of course, the members will themselves be streaming the game, and will preview the collaboration skins in a livestream event on Twitch and YouTube, to be held at March 17 at 8:30PM PST / March 18 at 12:30PM KST.
As Blizzard revealed in an interview with Polygon, this was a close collaboration with Le Sserafim’s members and Blizzard, specifically the team at Blizzard Korea Studio. Overwatch’s art director Dion Rogers put it this way:
“We try to work pretty close with our team in Korea on these particular skins. We did one of them here [in Irvine] as well, but because they’re close to this work, they have the best knowledge of how to translate what they see. […] We work closely with Le Sserafim as well, and the girls have their thoughts and ideas on what they like to see on the heroes. It’s a really fun collaborative process.”
Blizzard themselves chose which heroes would be part of the collaboration, based on which heroes would canonically actually be listening to Le Sserafim. The Korean team than had to place both practical considerations in choosing colors and outfits that would be trendy, and also be usable in a live service multiplayer shooter. Rogers also explained the members’ contributions:
“Le Sserafim actually contributed to the color designs. It’s very much inspired by their style, their fashion, and it was just cool to revisit those skins again and try to create a new palette for them.”
We imagine Le Sserafim themselves will be dishing more on how they helped make the new skins, so Fearnots who actually play the game will want to watch out for that livestream next week. In the meantime, you can watch the announcement trailer, that also previews their latest single So Cynical (Badum), below.
