Luna Snow () is the superhero identity of Seol Hee (), a South Korean K-pop idol who appears in media produced by American comic book publisher Marvel Comics. The character was introduced in Korean developer Netmarble's mobile game Marvel Future Fight in 2018, and made her comic book debut in War of the Realms: New Agents of Atlas #1 in 2019. Luna Snow was created by Bill Rosemann and Danny Koo of Marvel Games, and Jee-Hyung Lee of Netmarble.

When developing an update for the game Marvel Future Fight, South Korean mobile game developer Netmarble requested a character described as an "ice magician who could both heal and deal damage" for the game. Seol Hee was also developed in response to fan requests for more culturally diverse characters. Marvel Games Executive Creative Director Bill Rosemann remarked on her introduction, emphasizing that Marvel's global fanbase deserves heroes who not only inspire their support but also resonate with them on a personal level. The name Seol Hee translates to "snow" and "hope" in Korean.
Seol Hee is a South Korean superhero introduced in a 2018 update for the mobile game Marvel Future Fight. An aspiring singer, she aimed to support her family financially, eventually pursing a career as a K-Pop idol. During a live performance, she was taken hostage by the supervillain organization Advanced Idea Mechanics (A.I.M.), after she tried to protect the attendees of the event. After being trapped in a malfunctioning cold fusion reactor, she acquired ice-based superpowers and subsequently defeated the A.I.M. forces, adopting the superhero identity Luna Snow.
George Yang of Polygon felt that Luna represented Marvel engaging Asian characters more actively, particularly with the K-Pop demographic, and saw her use in games such as Marvel Rivals illustrating a commitment to representation. He felt with the growing fandom around K-Pop around the time and its use in similar titles such as Le Sserafim's collaboration with the game Overwatch, it was a logical step to introduce such a character, and that her presence in Rivals was in part intended to appeal to Korean gamers and comic book readers. He further expressed that in his view the inclusion of diverse characters like Luna helped expand the game's audience and present a "create a much richer and interesting universe".
In regards to her comic book appearances, David Brooke of AIPT described her introductory comic as a "classic case of an accident creating a hero", though felt her characterization and location helped provide a unique angle to the event. Despite this, he felt that she felt underutilized in the comic until she gained her powers, but blamed it in part on the story's reliance of secondary characters and enjoyed how her powers were illustrated. Despite his criticism, he expressed that Luna was a character he wanted to see in Marvel's cinematic universe, feeling there was a lot in her origin story that would get fans excited, and further compared her to the character Elsa from Disney's film Frozen "but better".
Additional coverage has focused on the characterâÂÂs increased visibility following her appearance in Rivals. Screen Rants Madelyn Champa stated that while Luna had a long-running presence in comics, the character had not seen mainstream success until the game. Describing her as its breakout star, Champa felt it not only helped expose her to a much larger audience, but as gave her "the popularity she's long deserved" and helped with her comeback in mainstream comics which referenced her outfits in Rivals. She additionally praised her Mirae 2099 skin design and its use in the comics, describing it as not only referencing the Marvel 2099 comic line her role as a K-Pop idol due to the large headphones and pink color scheme, while the long pigtails echoed the look of vocaloid character Hatsune Miku.
Nico Parungo of Gfinity eSports expressed surprised at Luna's summer skin for Rivals, stating that while her base design in the game was already revealing, "one-piece bathing suit takes things to the next level". He felt the developers were aware of this, as highlight reels particularly emphasized her sexuality in the new skin. While he did not see this emphasis as a bad thing, he did find it amusing to see coming from a billion-dollar franchise like Marvel's. He also acknoweldged that while the game did slant towards sexualization in the eyes of some fans, the design was not out of line with how some character costumes were portrayed in the comics themselves.
