She is married to Batman villain Mr. Freeze, and was introduced in the DC Animated Universe (DCAU) series Batman: The Animated Series, before being adapted into comics. Across most versions, Nora suffers from a terminal illness and is kept cryogenically frozen until a cure can be found.

However, the character has also been depicted as a supervillain, under the alias Lazara. Nora Fries made her live-action debut in the 1997 film Batman & Robin, portrayed by Vendela Kirsebom Thomessen. She has also appeared in the second season of Gotham portrayed by Kristen Hager, the 2018 Arrowverse crossover event Elseworlds, portrayed by Cassandra Jean Amell, and Batwoman portrayed by Jennifer Higgin when her aging started to continue rapidly. Fictional character biography DC Animated Universe After marrying Victor Fries, a GothCorp cryogenics researcher, Nora is diagnosed with a terminal illness. Victor uses the company's equipment to cryogenically freeze his wife until a cure can be found. However, GothCorp CEO Ferris Boyle cuts the funding and confronts Victor in the latter's laboratory to personally shut down the project, which subsequently leads to Victor being transformed into Mr. Freeze. In the Batman: The Animated Series episode "Heart of Ice", Nora is stated to be dead following the lab's destruction. However, the episode "Deep Freeze" reveals that Nora is still alive within her cryogenic chamber. As of the film Batman & Mr. Freeze: SubZero, Victor retrieved Nora's chamber and brought it to an Arctic cave until a submarine crew accidentally damages it. Victor murders the crew before bribing an old colleague into helping him kidnap Barbara Gordon as she shares Nora's rare blood type. While Batman intervenes and rescues Gordon, Nora is ultimately cured by Dr. Lyle Johnston of Wayne Enterprises. In The New Batman Adventures episode "Cold Comfort", Nora is said to have waited for the presumed dead Victor for some time before eventually marrying her doctor Francis D'Anjou. This subplot is expanded upon in volume two of The Batman Adventures tie-in comic series, in which D'Anjou stages his abduction and death to frame Victor and make Nora hate him.
