Fries represents the culmination of one of the Lady Bat's farther-reaching plans. While she was carefully studying the Lazarus Pit she'd taken over from Ra's al Ghul, she began to understand some of its restorative properties. She began to realize that it healed a body was much less interesting than how. While the end effect was always the same, the process varied by the nature of the damage done to the body.

After years of tests with rats and chimps, she was ready to move on to a human test subject. The problem was that no one was about to volunteer, and while kidnapping someone was the simpler and more straightforward option, if her calculations were correct, she wouldn't want what came out of the experiment determined to kill her.

Victoria and Nora Fries were two of Wayne Enterprise's bio-technology top scientists. Either of them were worth ten times what they were being paid, but they worked for less so they could focus on their own projects. One of these projects was the perfection of cryogenics.

When Nora developed Spinal Neurodegenerative Paralysis Syndrome, a broad, degenerative condition affecting the nervous tissue in the spine, gradually leading to paralysis, Victoria was forced to put her in cryogenic stasis to keep the disease at bay--but the technology wasn't fully ready.

An accident covered Victoria in cryogenics chemicals, almost killing her. Though she survived, she became unable to tolerate subzero temperatures, and left her skin an icy blue in color. Nora survived the process unscathed, so Victoria does what she must, anything she must, to gain resources and information with which she can save her wife.

Wayne Enterprises and Lady Bat bend over backward to accommodate her. She has her own laboratory with everything she asks for, and Lady Bat is quick to point her to possible avenues for information or resources. Victoria's mind became focused on the sole task of doing anything she must, hurting anyone she must, to save her wife.

What she doesn't know is that Lady Bat arranged the whole thing. From Nora's disease to the accident; the cryogenics chemicals were mixed with some of the syrupy liquid from the Lazarus Pit. Now she has a cold-hearted enforcer who can and will take anything Lady Bat asks for it if it leads to helping Nora, and anything might help, so Lady Bat deploys her frequently.

She doesn't stop Victoria from trying to save her wife, but Lady Bat does make sure there are no traces of her involvement, thus keeping Victoria a tenuous ally.
