I really like the original version(s) of Killer Frost. She had an interesting look, one of the more plausible explanations for just how ice-based powers work, and a scarily *ahem* cold-blooded attitude towards things. And nowadays, she wears a belly shirt and jeans, and is basically just another cold-based villain who makes with the zappy-zappy freeze rays. Feh. Also, these scans make her scenes in Crisis where she's been brain-jiggled into being madly in love with Firestorm rather amusing.
