Mr. Freeze was one of the Dynamic Duo's greatest enemies. Freeze is a deformed blue man, obsessed with freezing things with his freeze ray. Sometimes he has hair and sometimes he doesn't. During a fight in his secret laboratory some years ago, Dr. Art Schivel was covered in an experimental chemical he had been working with. Batman tried to save him, but the damage had already been done. The freezing chemical had somehow bonded with his body, and he could no longer survive in any temperature high
