Nora Fries

Nora Fries, also known as Mrs. Freeze, is a fictional character appearing in media published by DC Entertainment, commonly in stories featuring the superhero Batman. 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. As such, she usually does not have a major role in most stories beyond serving as Freeze's motivation for turning to crime to cure her by any means necessary. However, the character has also been depicted as a supervillain, under the alias Lazara.
