Tora Olafsdotter, known as Ice, is a superheroine in DC Comics renowned for her cryokinetic abilities and Norwegian origins. She first appeared in Justice League International #12 (April 1988), created by writers Keith Giffen and J.M. DeMatteis with artist Kevin Maguire. As the princess of a reclusive tribe of magical Norsemen possessing innate ice-manipulating powers, Tora left her isolated homeland to explore the wider world and use her abilities for good. Her powers enable her to generate and control ice, create constructs such as shields or projectiles, induce freezing temperatures, and manifest icy forms, establishing her as a formidable metahuman despite her gentle and reserved demeanor.

Ice initially joined the Global Guardians briefly before becoming a founding member of the Justice League International, where she adopted her enduring alias to distinguish herself from the original Icemaiden. Her tenure in the JLI highlighted her contrasting dynamic with the outgoing Fire (Beatriz da Costa), forging one of the team's most enduring friendships characterized by mutual support amid humorous and perilous missions. Ice's compassionate personality and romantic involvement with Green Lantern Guy Gardner added emotional depth to her role, contributing to the era's blend of camaraderie and international heroism.

Subsequent storylines introduced profound challenges, including Ice's sacrificial death during a confrontation with the Overmaster in Justice League Task Force #14 (1994). She was later resurrected through various narrative events, including influences from Blackest Night and subsequent revivals, allowing her return to active duty in teams such as the Justice League and Cadre. In contemporary continuities, Ice has explored personal growth, cultural heritage, and evolving power sets—such as temporary exchanges with Fire—while maintaining her status as a symbol of resilience and quiet strength within the DC Universe.
