Development

Concept and creation 
The name of Seol Hee translates to "snow" and "hope" in Korean. She first appeared as an original character in the video game Marvel Future Fight in 2018. The South Korean mobile game developer Netmarble requested an "ice magician who could both heal and deal damage" for the game. She was also created in response to comic book readers asking for more characters that are more culturally diverse. Marvel Games Executive Creative Director Bill Rosemann commented on her debut, "Marvel has the greatest fans around the world, and they deserve heroes that they can not only cheer on as they fight evil, but also connect with on a personal level." Marvel Entertainment subsequently released several promotional singles for Luna Snow. Seol Hee was later introduced in the Marvel Universe in 2019.
