Appearence:

History: Dr.Victor Fries was one of Gothcorp's most brilliant scientists and cryogenic researchers, however he was unable to cure his wife Nora of a deadly disease. His research in cryogenics was eventually cut off by the bureaucrats at Gothcorp. His experiment to create a cryogenic freezing chamber to house his wife until a cure could be found was interrupted by Ferris Boyle, C.E.O. of Gothcorp, and his security guards. A fight ensued, accompanied by an explosion. In the explosion, Dr.Fries was smashed into his cryogenic freezing tanks. The accident soaked Dr. Fries's entire body with the freezing solution and rendered him unable to survive outside of a sub-zero environment. He vowed revenge on those who had wronged him. He was forced to create a vacuum tight suit which maintained his body temperature at 50 degrees below zero. The suit's cybernetic processor also tripled his strength. After building a laser-powered cold gun, Mr. Freeze was born.

Driven by hatred over the destruction of his life and maddened by his condition he pursues a life of crime and vengeance by destroying Ferris Boyle and crippling Gothcorp. His plans are stopped by Batman. Mr.Freeze becomes bent on destroying Batman since he blocked his mission for revenge. He is a quiet, but dangerous adversary. Mr.Freeze is an angry and saddened man, who is sentenced to Arkham Asylum when apprehended. A special cell is designed to maintain his need for a frozen environment. He is alone and his only motivation comes from his wife's music box, which he holds as his last piece of the happiness he once had. He is viewed as an loner by the rogues gallery, and generally does not hold alliances with any of the other inmates of Arkham. Batman knows he is a dangerous adversary, and that the traumas that have occurred in Mr.Freeze's life are scars which will never heal.

Audition

After breaking out of Arkham by use of his freeze gun Victor Fries, who is more known as Mr. Freeze, walked down one of the empty streets of Gotham. As he walked he froze parts of the road and some of the buildings inch by inch with his gun. Since his real plan was to turn the whole of Gotham into a giant icecube and once he accomplished this not even the bat would be able to stop him.

Freeze smirked at the thought of his winter wonderland. He was so wrapped up in his thoughts that he didn't notice a police car stop in front of him. All of the police department knew of his escape and what he was capeable of.
"Stop right there!" one of the officers shouted as they pointed their gun at him, smightly unerved by Freeze's venomous look.
"You seem awfully hot under the collar, so I suggest you cool off," Freeze replied as he pointed his own gun at the officer, fireing before the cop could get a shot off and freezing him in his tracks. The cop became a block of ice before their very eyes.
"Is there anyone else who wants to be a hero?" Freeze asked cooly as he looked at all of them in turn.
The other cops were about to say no when a large shape covered the sky above their heads.
Freeze frowned and glared as Batman dropped in front of him. "You've made a big mistake coming here Batman," he said.
