Mr. Freeze is Victor Fries, a brilliant cryogenic scientist whose life changed forever after a laboratory accident left him dependent on subzero temperatures to survive. Mr. Freeze turned to crime to fund research that could cure and revive his beloved wife, Nora, who remains preserved in cryogenic suspension. Although he often clashes with Batman, his actions are usually driven by grief rather than simple malice. His tragic story has made him one of Gotham City's most sympathetic and memorable villains.
