Mr. Freeze (DC Animated Universe)

Victor Fries, a.k.a Mr. Freeze is an enemy of Batman and a recurring villain in Batman: The Animated Series. He was a brilliant scientist and cryogenic researcher who turned to a life of crime after a lab accident altered his physiology, forcing him to live his life inside a suit that kept his body perpetually cold.

Batman: The Animated Series
When his wife, Nora, was diagnosed with a deadly disease, Fries put her into a suspended animation state until he could find a cure. However Ferris Boyle, CEO of GothCorp and Fries' boss, wanted Nora's cryogenic capsule shut down as he considered it a drain on resources and funds. Fries tried to stop him, but was doused with cryogenic chemicals in the ensuing struggle, mutating him by altering his skin color and rendering him incapable of surviving outside of a sub-zero environment. He build a special cryogenic suit that helped him to survive, keeping him cold. Thanks to the suit, Fries gained superhuman strength and endurance. He would later develop a freeze-ray weapon that would allow him to freeze victims solid.

The New Batman Adventures
Mr. Freeze made a single appearance in the episode "Cold Comfort". Years before this episode's events, Freeze's wife Nora had been cured of her illness, but Victor never reunited with her out of shame over his condition. When he next appeared in Gotham, Freeze had been driven to a state of spiteful rage and resolved to destroy all that was warm in Gotham, anything that was of emotional value to anyone. However, when Batman and his allies confronted Freeze, they were shocked to find that Freeze's body was robotic, his original body having deteriorated until he was reduced to a head attached to a spider-like mechanical base. Freeze attempted to crush Batman's hope by freezing all of Gotham using a "reverse fusion bomb". Fortunately for Gotham, Batman and Batgirl managed to catch up to Freeze, and Batman encountered him within his bomber plane. A battle ensued in the plane with Freeze greatly overpowering Batman. Freeze was about throw Batman out of the plane, but managed to latch Freeze onto his bomb via grapple gun. With the bomber plane flown over the ocean, Batman opened the plane's hatch dropped the bomb over the water with its maker attached to it. The blast created an enormous pillar of ice in the water, with Freeze's suit trapped within. However, the cryogenic suit was without Freeze's head, revealing that the icy villain had managed to escape.

Batman Beyond
Mr. Freeze would make his final appearance in the DCAU in the Batman Beyond episode "Meltdown". After being kept in cold storage for decades, Freeze was given a new lease on life when Dr. Stephanie Lake of Wayne-Powers offered to create a new clone body for him and transfer his mind into it. The procedure appeared to be successful; Victor awoke in a new body that was able to survive in normal temperatures.

For a few brief days, Victor enjoyed having a normal life once again and even tried to make reparations to the families of his previous victims. However, his happiness was all too temporary as his body began to revert, becoming intolerant of warm temperatures. He returned to Dr. Lake for help, but Lake had originally used Victor as a test subject to create a new body for Derek Powers, who was suffering from a radioactive mutation. Seeing the experiment with Victor as a failure, Powers ordered Dr. Lake to biopsy Victor's organs before they completely failed to see if they could still be of use. However, Victor was able to muster enough strength to escape the lab and flee.

Returning to one of his old cold storage facilities, Victor donned a new hi-tech cryo-suit with which to take his revenge on both Lake and Powers. He returned to the Wayne-Powers compound where he froze Dr. Lake to death and also froze Powers. However, Powers' mutation prevented him from succumbing to the extreme cold and he attacked Mr. Freeze with radioactive blasts. Terry McGinniss, the new Batman, arrived on the scene to stop Freeze's rampage, but was also attacked by Blight. In the end, Freeze saved Batman by blasting Blight through a wall. As the facility was about to self-destruct, the injured Freeze froze the surrounding structure to hold it together long enough for Batman to escape. Batman urged Freeze to come with him, but Freeze said that no one other than him cared, resigning himself to his fate. With time running out, Batman was forced to leave while Freeze stayed behind, the facility exploding around him.

Appearance
After the mutation caused by the cryogenic accident, Mr. Freeze hainedas a unique physiology, as he looks like an alien-like humanoid with pale blue skin with red goggles covering his eyes and an expressionless face. He wears a hi-tech cryogenic suit which he needs in order to survive. In Batman Beyond, his appearance is more inhuman, since his face is almost covered by the mist within his helmet and his red eyes glow even more, apart from his armor it looks more imposing, thus looking like a cyborg.

Powers and Abilities
The mutation caused by the accident gave Fries the ability to live in sub-zero temperatures. However, he cannot live outside of them, so he relies on a special suit that keeps him cold enough to help him survive outside of the frozen environment. Thanks to the suit, he possesses superhuman strength, endurance and longevity. That is, he is incapable of aging. He has even been able to live for many years with his head separated from his body, as seen in Batman Beyond.

Mr. Freeze is highly intelligent, being a master of cryogenic science and a skilled mechanical engineer. He designed and built the suit he wears as well as his trademark freeze-gun, which allows him to freeze victims in solid blocks of ice. He presumably also designed the cybernetic components he would use in The New Batman Adventures. In Batman Beyond, Freeze's weaponry was integrated directly into his latest suit, allowing him to project blasts of cold from his hands.
