Mr. Freeze

Mr. Freeze is a supervillain appearing in American comic books published by DC Comics. The character was created by Dave Wood, Sheldon Moldoff, and Bob Kane, and first appeared in Batman #121 as the ice-based criminal Mr. Zero. He was soon renamed "Mr. Freeze" and, years later, received a revamped origin story based on the one conceived by writer Paul Dini for Batman: The Animated Series. Dini's depiction of the character as a tragic villain popularized Mr. Freeze into becoming one of Batman's most enduring enemies belonging to the collective of adversaries that make up his rogues gallery.
