Mr. Freeze is the tertiary antagonist in the cartoon series The Batman. In this series, Victor Fries was a common bank robber who was chased into an experimental laboratory by Batman. He became trapped in a chamber that mutated his body into a walking icicle. After this he convinced a scientist to make him a suit to better control his newfound powers. With this done he desired freeze Gotham, steal it's valuables and ultimately kill Batman himself. He's portrayed as a person with no regard for others lives, cold yet calculating and ultimately greedy individual looking our only for himself.
This is the only post–DCAU version of Mr. Freeze who does not have a wife and tragic backstory; even the poorly received film Batman and Robin incorporated this. This, along with other character changes, is one of the reasons The Batman is criticized by a decent number of Batman fans.
