As a classic member of Batman’s rogue gallery, Mr Freeze is one of the Dark Knight’s most prolific enemies. Starting off as a throw-away character called Mr Zero in the 1960s, Freeze was transformed into a more complex character in Batman: The Animated Series.
Victor Fries became a scientist who was fascinated with cryogenics. He fell in love with a woman called Nora, but after learning that she’d contracted a fatal illness, Victor was determined to find he cure.
He froze Nora in suspended animation, only to have his experiments ruined by his boss, Ferris Boyle. The interference caused an explosion, which lowered Victor’s body temperature to the point he could only survive with a special suit. Vowing revenge on Boyle, Mr Freeze turned to a life of crime.
Freeze’s tragic origin story ties into his desire to bring his wife back to life. In his quest to cure Nora’s disease, Freeze has done terrible things in the name of love. Other times, Freeze has been so focused on his cryogenic research that he’s killed anyone who stood in his way, but sometimes his cold-hearted nature can take things to the extreme, to the point where he’s cemented himself as not just one of Batman’s greatest adversaries, but also his most ruthless.
