Blizzard and Source Music have posted the complete teaser art for the third Overwatch 2 x LE SSERAFIM collaboration, confirming LE SSERAFIM-inspired cosmetics for six heroes: Mizuki, Freja, D.Mon, Anran, Sierra, and Moira. The reveal follows weeks of hints that began when Busan’s in-game billboards flipped to LE SSERAFIM’s logo at the end of the Season 4: Heroes of Busan launch trailer in mid-August. The new skins go live on September 12, 2026, the opening day of BlizzCon 2026, where LE SSERAFIM will also perform.
Six Heroes, One Collection
The lineup pairs LE SSERAFIM’s identity with a mix of brand-new and veteran heroes. Four of the six, Mizuki, D.Mon, Anran, and Sierra, are heroes introduced this year, while Freja and Moira are established heroes that we don’t often see get skins of this scale.
- D.Mon (Yuna Lee): The newest addition of Season 4: Heroes of Busan. Yuna Lee leads the MEKA Squad and pilots a mech named Beast, fighting with a Plasma Saber, a Power Barrier, and Propulsors.
- Mizuki: One of the newer heroes joining the collaboration’s cosmetic lineup.
- Anran: One of the newer heroes joining the collaboration’s cosmetic lineup.
- Sierra: One of the newer heroes joining the collaboration’s cosmetic lineup.
- Freja: An established hero with a dedicated fanbase that rarely receives skins of this scale.
- Moira: A veteran support hero and another rare cosmetic pick for the collaboration.

A Return Three Years in the Making
LE SSERAFIM and Overwatch first teamed up around BlizzCon 2023, where the group debuted their single “Perfect Night” on the BlizzCon stage as part of a collaboration that included an in-game event and a set of themed hero skins. Instead of the usual two-song set, LE SSERAFIM played a 30-minute, fancon-style performance that fans still bring up whenever a new wave gets teased. The partnership returned for a second wave in 2025, and this new lineup marks the third collaboration between Blizzard and the group’s label, Source Music.
For anyone who missed it the first time, here’s LE SSERAFIM’s full BlizzCon 2023 stage:
Set to Close BlizzCon 2026
BlizzCon 2026 returns to the Anaheim Convention Center on September 12 and 13. LE SSERAFIM is confirmed to perform the convention’s closing set on the main stage on September 13, once again following their 2023 stage debut. BlizzCon passes are officially sold out, though resale tickets have circulated through secondary marketplaces.
The timing lines up with LE SSERAFIM’s own release calendar. The group’s new single, “Made My Night,” arrives September 11, 2026, one day ahead of the Overwatch skins and two days before their BlizzCon performance. BlizzCon also falls in the middle of the group’s Pureflow world tour, which continues with a Los Angeles stop on September 16.
K/DA Rumors Add to the Buzz
Separately, League of Legends leak accounts, including League of Legends Leaks, have claimed that Riot Games’ virtual group K/DA is preparing a comeback with new music and skins, a rumor picked up by outlets such as Insider Gaming. Riot has not confirmed a K/DA return, and the claim remains unverified. If a comeback does materialize, it would land well after BlizzCon 2026, since the 2026 League of Legends World Championship runs October 15 through November 14 across Los Angeles, Allen, Texas, and New York City, with the final at Barclays Center.
