- ―Mr. Freeze[src]
Nora Fries is the beloved wife of scientist Victor Fries, whose fate would set events in motion for his transformation into the villain known as Mr. Freeze.
Nora was suffering from a rare terminal illness, so her husband Victor cryogenically froze her in stasis while he worked on a cure. The process was interrupted by Ferris Boyle which led to Victor's disfiguration, and him becoming Mr. Freeze. Freeze thought Nora to be dead and set out on a vendetta to avenge his wife, although he was stopped by Batman.
Nora turned out to be alive after all and was sheltered by Grant Walker. He broke Freeze out of Arkham Asylum and showed him his wife again. He made a deal with Freeze to help fund his search for a cure in return for giving Walker a stasis suit granting him immortality.
Fries later settles in the Arctic, accompanied by his Nora. An expedition submarine compromised Fries' cave, initiating ice to smash open Nora's capsule. Furious by the oblivious expedition's unintended blunder, Victor freezes them all, and moves back to Gotham City. While there, he solicits the assistance of former co-worker and ethically-corrupt doctor Gregory Belson. Belson informed Freeze that Nora's condition required a major organ transplant, and her blood type was uncommon. He kidnapped Barbara Gordon after Belson found her to be a corresponding donor for Nora.
Batman and Robin intervened, and stopped Freeze. Returning to the Arctic, he gazed into a scientific outpost and saw a TV news bulletin, hearing that Nora made a full recovery with the assistance of study from Wayne Enterprises. Contented tears in his eyes, Fries limped away into a snowstorm.
