Mr. Freeze

Mr. Freeze is a member of The Rogues and one of Batman's archenemies.

History
A cryogenic experiment gone wrong permanently lowered Dr. Victor Fries’s body temperature, turning him into the sub-zero super-villain Mr. Freeze. Forced to wear a special suit to survive, the cold-hearted and nearly emotionless crook uses his scientific skills and freeze gun to bring a chill to Gotham City wherever he goes. Good thing Batman is always there to bring the heat!
