Dr. Victor Fries was a mere Gotham City scientist who used cryo-stasis technology to resurrect his wife Nora who had a rare disease, so he could have more time to save her. However an accident in the laboratory caused his body temperature to revert to below zero and was forced to wear a refrigeration suit to survive the mutations. Fries then deemed himself "Mr. Freeze" and staged robberies in order to fund his project.Mr. Freeze became the first super villain Batman fought; he had only encountered "plain clothes" villains before Freeze.
