Chill! During an altercation in his secret laboratory, Dr. Art Schivel was covered in an experimental chemical he had created. The chemicals bonded to his body, and suddenly his metabolism was reversed, and outside fifty degrees below zero could not survive. He created and wore a special suit that kept his body constantly at a freezing temperature and his lair was always Arctic in temperature. From then on, he referred to himself as Mr. Freeze. He vowed revenge on Batman and all of Gotham to suffer and freeze like he did. That is the way the ice cube crumbles!
