The Gotham City Criminal Underground
The man who became known as Mr. Freeze has shrouded his early years in mystery, and so no one knows who this man was before the bizarre accident that transformed him into a twisted super-criminal.
Originally a sophisticated criminal with a brilliant scientific mind, he one day was constructing a gun capable of emitting waves of frigid cold when a freak accident bathed him in an experimental freezing solution. Almost immediately, the criminal scientist was unable to survive in a normal setting, requiring a special environment below -32 degrees centigrade. A short time later, the criminal fashioned a refrigerated uniform and set out to begin a crime spree through Gotham City as Mr. Zero.
While initially successful, Mr. Zero was eventually defeated by Batman. This was a short-lived triumph for the Caped Crusader, because Mr. Zero returned several times. Despite the ingenious plans and traps Mr. Zero launched, he was defeated time and time again.
Hoping to reverse the defeats, Mr. Zero improved is cold gun and uniform, changed his name to Mr. Freeze, and began anew. Mr. Freeze remains undaunted, although each defeat leaves his mind seemingly all the more unhinged. Mr. Freeze has preferred working with a small gang of thugs and his last known attack was to plunge Gotham into a miniature ice age, with himself as the new ruler. He was, of course, captured by Batman.
Since then, Mr. Freeze has escaped from Gotham Prison and has modified his battle armor once again, remaining a threat to Gotham's citizenry.
