While Killer Frost is certainly a recognizable comic book character, its a safe assumption that most of what people know about her is stemming from The Flash. Theyve stayed true to portions of the character, but one of the biggest deviations has been in her relationship with Ronnie Raymond, one half of Firestorm. Thats because in the comics, theyre not lovers, theyre bitter enemies. No matter the version of the character, Killer Frost has always had it out for Firestorm. The original was spurned by Martin Stein, half of his alter-ego. Then theres Louise Lincoln, who blamed him for her friends death. Finally, in modern times, Killer Frost sees Firestorm as an endless supply of fuel. That Killer Frosts greatest nemesis is Firestorm shouldn't be much of a surprise, fire and ice are natural opposites, after all. Their connection goes beyond that, however, because of Firestorms ability to manipulate particles and matter. Killer Frosts condition goes beyond the realm of what he can fix and that connection has always bound their powers together as well.
