Origin

Seol Hee was an aspiring young singer hoping to become a K-Idol and earn enough money to take care of her grandmother. Seol got her big break being chosen as part of a new girl group 4L1T. Taking on the stage name Luna, alongside groupmates Minni, Hae Won and Jessica, 4L1T hosted their debut performance at Stark Arena in Seoul. The group's manager had unknowingly bought tech from A.I.M. scientist the Joro Spider to "boost the performance's SFX," which would breach Stark's security and grant Joro access to the facility's cold fusion energy. When A.I.M. ambushed the event, Seol tried to defend the innocent people attending 4L1T's show.

However she was easily overpowered and the A.I.M soldiers locked her in the cryo-reactor. While attempting to escape the reactor Seol was exposed to a blast of cold-fusion energy, and the combination of radiation and intense cold gave Seol the power to create light and dark ice crystals. Seol used these strange powers to protect her friends and defeat the A.I.M. guards, before fighting Joro Spider and forcing her to retreat. The crowd cheers her stage name - "Luna! Luna Snow!" - and Seol becomes an overnight Idol/superhero sensation.

Creation

Luna Snow was created Danny Koo, Bill Rosemann and Jeehyung Lee for the mobile game Marvel Future Fight. Her comic book debut was in War of the Realms: New Agents of Atlas issue 1 (2019), by Greg Pak and Gang Hyuk Lim.

Major Story Arcs

Joining the New Agents of Atlas

As part of Malekith's invasion of Midgard, the fire giantess Sindr commanded her demons of Muspelheim against the armed forces of South Korea and the people of Seoul. Luna Snow intervenes alongside fellow South Korean heroes White Fox and Crescent and Io, helping civilians escape before the Agents of Atlas can provide assistance. In the ensuing battle Seol's powers are turned against her and she is captured by Sindr within the Gyeongbokgung Palace, but is quickly rescued by Amadeus Cho and Luna Snow formally joins the New Agents of Atlas.

To counter Sindr's melting of the polar ice caps, Luna Snow is teamed up Shanghainese hero Aero and Filipina newcomer Wave to form a trio dubbed the Elementals. While Cho distracts Sindr and her army, the trio leap through the Queen of Muspelheim's portal and combine their powers of water, wind and ice to create a vast tornado that rapidly cools the Arctic climate. Once the damage is reversed, the Elementals rejoin their fellow Agents of Atlas at the Great Wall of China north of Beijing to defeat Sindr for good.

Portal City of Pan & Atlantis Attacks

Luna Snow reunites with the Elementals to lure and send home a stray fire dragon from Sindr's invasion. There she, along with the Agents of Atlas, encounter a new hero called Protector who brings them to the new city of Pan. Pan is a city made up of numerous Asian cities around the globe, brought together through portal technology masterminded by billionaire CEO Mike Nguyen. Pan is almost immediately bombarded by numerous wyvern attacks which Seol Hee and her teammates fight back, defending the city's tourists all while Seol balances flirtationus advances by both Protector and Amadeus. The Agents are officially branded the new "Heroes of Pan," but with her business savvy Seol Hee sees through Nguyen's PR gimmicks, and confides her suspicions of Pan's utopian facade with Amadeus. The two begin to bond which reveals a potential romantic attraction, but the two are interrupted when Pan soldiers begin attacking Madripoorian immigrants who have made a long perilous journey by sea to get to Pan. Both heroes ardently defend the immigrants and Protector reels in the guards, apologising and promising to keep the people safe. Now alone, Seol Hee and Amadeus kiss, a private moment that is captured by surveillance cameras and weaponized by Nguyen as part of his Pan Pass marketing campaign. Luna is outraged by Nguyen's illegal use of their kiss - as K-Pop stars have non-dating clauses in their contracts and the footage could could destroy her career - so she sues for copyright and trademark infringement in response. Nguyen settles with Luna, however the publicity of their intimate moment and potential risk to Seol's idol career sours any romantic potential the couple could have had.

The source of Pan's magical portal technology is soon revealed to be powered by a kidnapped Atlantian dragon, and King Namor launches a singular invasion of the city. Luna is among the Agents of Atlas who want no part in the war, insisting that it is their job to protect civilians and aid in evacuation efforts. When Namor returns to Pan in a blind rage to kill Mike Nguyen and sink the city, Luna Snow and Aero manage to hold him back for an extended time until the team formulates a plan.

Silk Team-Up

While Korean-America superhero Silk was a huge fan of Luna Snow the K-idol, the two became genuine friends working together as part of the Agents of Atlas. Both were the moral center of the team, consistently defending the rights of the people of Pan, and Seol Hee appreciated Cindy Moon's friendship with her as an actual person. After the battle between Atlantis and Pan, Luna Snow begins her first U.S. solo tour to promote her new album and sends Silk tickets to attend her sold out NYC concert at Madison Square Garden. Silk is currently investigating the mystery surrounding a 17th Century Manyeo (Korean witch), and her warriors attempt to kidnap Luna in the middle of her performance. Cindy suits up as Silk and intervenes the brawl breaking out between Luna and the warriors on stage, which the two ladies win to the crowd's fervant applause. After the concert ends Luna invites Cindy back to her dressing room, where she offers her assistance in defeating the Manyeo, but Cindy declines and reminds Seol she still has a tour to finish.

Joining Tiger Division

Off-panel, White Fox officially invites Luna Snow to join the National Intelligence Service's superhuman response team Tiger Division. Shortly after she joins, the team's heavy hitter Taegukgi is mind controlled by the gangsters Choi Faction, who threatens to unleash him upon Seoul unless the government cede control of state to them. White Fox blackmails the American thief Black Cat to assist with the team's rescue operation, and the team set off from their base on Burasam Mountain to investigate the Choi's hideout at an abandoned DMZ ski resort. While Fox & Cat investigate the resort, Luna joins the rest of her team in "distracting" South Korea's most powerful superhuman. Tiger Division are woefully outmatched and Luna is injured in the battle, being guarded by her teammate Lady Bright's sorcery before a falling building can crush them. The team hold on long enough for Fox & Cat to locate the man psychically possessing Taegukgi's body, Mongdal, and free Taegukgi from his control.

Concert of Champions

Luna Snow later joins a line-up of huge musical superstars - including Dazzler and Lila Cheney - as headliner of the California-based festival Concert of Champions. She clashes with Dazzler over her commitment to the fans and the concert's schedule, not knowing that the mutant songstress' mental health is spiralling after a series of scandals and attacks. Their conflict is shelved when a suspicious metal band called Deep Void gatecrashes the festival and, while Lila and Luna decide to confront the newcomers, Dazzler shuts herself off within her trailer. Gwen Stacy, a guest at the festival, helps confront Deep Void in her Ghost-Spider costume and Lila teleports the crowd to safety while Luna attacks Angar the Screamer, Forearm, and Ruby Thursday. Dazzler overcomes her fears and joins Luna, Ghost-Spider and Domino, and together the women defeat Deep Void. The ladies regroup and perform an uplifting anthem together, this time with Gwen Stacy on drums, as Marvel's first supergroup.

One World Under Doom

After Victor Von Doom announces a state of Pax Victoris, Tiger Division is drafted in defeating a Bulgae while filming a music video for Luna, that includes pro-Doom messaging and lyrics welcoming Doom's "evergreen peace." Luna expresses concern for its potential immorality, however her producer Mr. Baek insists that she must comply to continue being profitable for the company. At her halmoni's apartment, Seol laments being strong-armed into making propaganda. Her grandmother states that Korea is a place of constant change, prospering now, but to remember that Japan's occupation came under the guise of prosperity and modernization. Luna must keep an open, but wary, mind on Doom's impact on Korea.

After nine days of Doom's new emergency response drones, Tiger Division begin to feel redundant and debate the validity of Doom's rule. Director Han orders them back to headquarters and announces Doom's Pan-Asian expansion protocol, revealing Aero, Wave and Karma as Tiger Division's new team members. With the regional alliance comes rebranding, and Tiger Division are renamed Doom's Division. While the rest of the team are sent to aprehend the renegade Sunfire, who defies Doom's world order, Luna is ordered to stay behind and produce her new pro-Doom pop album. The record is fast-tracked in days and Luna is sent on a publicity tour, being coerced to feign happiness at Doom's rule. At a Seoul stadium rehearsal Luna feels sick singing propaganda, but meeting fans whose medical treatment was expedited by Doom's new legislation convinces Luna she can't let the people who depend on her down.

Standing on stage, Seol receives a magical messages from Lady Bright informing her that Sunfire is dead, and White Fox betrayed them. Luna leaves the concert and heads to Buramsan Mountain, where she finds Tiger Division fighting off White Fox in her kumiho form. Luna joins the team and pursues White Fox when she flees, and traps her within an ice shard cage. When White Fox reveals she and Sunfire had been working against Doom from the start, Luna feels guilt for not fighting against her record label from the start. Together, the heroes go into hiding.
