Crystal Frost

Crystal Frost was a scientist who developed the ability to absorb and project intense cold after an accident in an Arctic research facility. Her unrequited feelings for Martin Stein, one half of the hero Firestorm, drove her to become the villain Killer Frost.

Emerging from the Bronze Age DC Universe in 1978, Crystal Frost made her debut in the pages of Firestorm #3, brought to life by writer Gerry Conway and artist Al Milgrom — a creative team that knew how to craft characters who linger in readers' memories. Over a publishing history that stretched across more than three decades, she carved out her place most prominently in The Fury of Firestorm and Justice League of America, sharing those pages with heavyweights like Firestorm, The Flash, and Hawkman. With a key-issue appearance to her name and a legacy that connects her to the Killer Frost mythology, Crystal Frost is one of those rewarding deep-dive discoveries that reminds collectors just how rich the Bronze Age DC vault truly is.
