Nora Fries was the terminally ill wife of Dr. Victor Fries, who later became the supervillain, Mr. Freeze.
Years before his transformation, Dr. Victor Fries met Nora. The two fell in love and married around the time Batman began operating in Gotham. However, Nora soon fell ill with an incurable and deadly disease. Struggling to find a cure, Victor placed her in a cutting edge cryostasis chamber, to give him more time to find one for her. However, his boss, Ferris Boyle, found out about what he planned and stole Nora, also causing Victor's transformation to Mr. Freeze. Nora would be kept by Boyle for some time before New Years Eve that year.
In order to rescue Nora, Victor, now a criminal called "Mr. Freeze", made an agreement with the new Gotham crime lord, Penguin to break into GothCorp and kidnapped Boyle to access the necessary security codes to her confinements. However, the attack gained Batman's attention and led to a between them as he attempted to retrieve her chamber. This led to a fight after the Dark Knight shut down the coolant supplies, damaging Nora's chambers. After defeating Freeze and subduing Boyle, Batman fixed Nora's chamber, saving her life.
As part of his incarceration in the city, Victor Fries arranged for his wife Nora to be moved into the city for him to continue his research into finding a way to save her life. Hugo Strange arranged to have Nora kidnapped as leverage on Fries during his psychological evaluation. After Strange learned all he could, he had Nora transported to the Joker, who is near death and needed Fries' medical knowledge. The body was hidden in an abandoned Falcone warehouse with explicit instructions to Victor that she'll only be released should he develop a cure for the disease killing Joker; however, Victor soon realizes that there is no cure (more specifically, the cure breaks down in a short period of time).
Nora's cryogenic chamber is left in the possession of several of Joker's men, many of whom express interest in thawing and raping Nora, leaving her in a state of constant danger. Fries and Nora are reunited when Batman discovers her in the city and disables her guardians. Victor can be seen with Nora after he is informed of her location, and when visited by Batman he tells Fries to give up a life of crime for her.
Nora made in appearance in Batman: Arkham Knight, but only if the Season of Infamy DLC pack was downloaded. The Arkham Knight and his militia attempted to convince Mr. Freeze to assist in taking down Batman, but he declined. In revenge and in the hopes of changing his mind, the Knight took away Nora from Freeze.
