Lazara was once known as a gentle and attractive woman whom married Victor Fries. Unfortunately, she was suddenly ill with a deadly disease that forced Dr. Fries, whom later became supervillain named Mr. Freeze, put her into cryostasis, hoping to sustain her until a cure can be found.
Over time she falls to pieces in her ice state, but Freeze puts her back together again.
Freeze helps Nyssa al Ghul by creating a machine for the Society that can also be used to capture Batgirl. In return, Nyssa has offered to help him restore his wife using the Lazarus Pit. Though Nyssa has told him the pit needs to be adjusted for Nora, Batgirl convinces Freeze that Nyssa has no intention of reviving her at all, and he throws Nora into the pit himself. Unfortunately, because of all the years of being altered and broken, Nora absorbs the pit's alchemy, acquiring the powers to conjure flame and reanimate the dead. She becomes a supervillainess, calling herself Lazara. Mr. Freeze manages to stop her by freezing her once again.
