Luna Snow Fact — November 2, 2026

Today's Fact

Plenty of heroes throw ice. Seol Hee is the rare one whose frostbite comes with a bedside manner attached.

LUNA SNOW'S ICE COMES IN TWO KINDS — DARK ICE THAT DESTROYS AND LIGHT ICE THAT HEALS!

The Featured Fact

Seol Hee — the K-pop idol who performs as Luna Snow — does not command one kind of ice but two. Her cryokinesis splits into dark ice, a corrosive, destructive frost that shatters and decays what it touches, and light ice, a restorative cold she uses to heal wounds and steady allies. The same power that freezes an enemy solid can close a teammate's bleeding.

The split arrived with the accident that made her. Performing with her trainee group 4L1T at Stark Arena, Seol Hee tried to shield the crowd when an A.I.M. cell led by the Joro Spider attacked; the attackers locked her inside a malfunctioning Stark cold-fusion reactor, and the energy that flooded her as she escaped rewired her into a living study in opposites.

Marvel's profiles lean into the duality rather than treating it as decoration: her hair turned half-black and half-white, her stage act and her hero work both run on contrast, and later appearances with the Agents of Atlas and the Tiger Division keep assigning her the moment where the battlefield needs damage in one direction and mercy in the other — sometimes in the same breath.

Why It's Obscure

A healer hidden inside a blizzard: why the two-tone frost tends to get flattened into 'generic ice powers' in short summaries.

The two settings

Dark for harm, light for healing — Luna's dark ice corrodes and destabilises matter at a molecular level, while her light ice carries restorative energy; switching between them is a deliberate act, not a mood.

The reactor

Cold fusion, live on stage — Seol Hee gained her powers escaping the malfunctioning reactor A.I.M. trapped her in during 4L1T's Stark Arena performance, then turned the frost on the Joro Spider's cell.

The look

Half and half — Her hair split black on one side and white on the other, a permanent visual receipt for the two natures of her ice; the gallery's lead portrait shows both at once.

The day job

Idol first, medic second — Between Atlas missions Seol Hee still records and performs as Luna, which makes her possibly the only Marvel hero whose power set doubles as stage lighting.
