Mr. Freeze in “The Big Chill”

[explaining his transformation] I was electrocuted. At the same instant, the blood froze in my veins. Was I still among the living? Presumably, the experts would determine that, but I made their job easy for them. My body had mutated. Neither living nor dead. I was a walking cryonic miracle, though some might consider me a monstrosity. It didn't take much for me to motivate an expert in the field to produce a suit to contain my frosty disposition... until I so choose to disperse it.
