D.Mon, aka Yuna Lee, is a member of Korea's MEKA Squad. Like her teammate D.Va, D.Mon is a former esports pro turned mech pilot who fought alongside the Korean Mobile Exo-Force in the war against the Gwishin omnics. D.Mon has previously appeared in or been referenced in cinematics, cosmetics, and comics; she's been described as "tough and protective" by former Overwatch writer Michael Chu. D.Mon's mech is named Beast.
Players will get a longer look at D.Mon in her hero trailer, which will premiere on Thursday, Aug. 6 at 9 a.m. PDT / 12 p.m. EDT.
D.Mon, a Tank-class hero, has been teased throughout Overwatch's recent relaunch. She appeared as one of the silhouettes in the artwork that Blizzard released in February when it renamed Overwatch 2 to Overwatch, and promised 10 new heroes in 2026 as part of the game's 10th anniversary.
On Monday, Blizzard released a small glimpse of D.Mon's animated hero trailer, showing what appears to be her in battle with another mechanized menace, Wrecking Ball. We get a peek at Beast in action, though it's not yet clear how D.Mon will play differently from her MEKA teammate D.Va.
D.Mon is Overwatch's 53rd hero, the game's 15th tank, and the eighth new hero added to the game in 2026. She follows newcomers Shion (Damage), Sierra (Damage), Domina (Tank), Anran (Damage), Emre (Damage), Jetpack Cat (Support), and Mizuki (Support). D.Mon joins the roster officially on Aug. 11, when Overwatch season 4 goes live.
Overwatch is available on Nintendo Switch, Nintendo Switch 2, PlayStation 4, PlayStation 5, Windows PC, Xbox One, and Xbox Series X.
