When A.I.M. ambushed a Stark Industries party where aspiring singer Seol Hee was performing, her attempts to defend the partygoers caused A.I.M. agents to lock her in a storage freezer. During her escape, she knocked over the contents of an energy experiment, exposing her to elements that granted her ice powers which she then used to defeat A.I.M. Her heroic actions made her an overnight sensation, and she continues to use her talent and powers under the name "Luna Snow" -- part time pop star, part-time Super Hero.
