Caitlin Snow (Earth-8026)

"Do you have any idea what it's like? To have two versions of yourself inside... so radically different, yet somehow completely the same person. I want to be good, I want to be good so bad it hurts my head, because that other part of me... she's living off of killer instinct. She's coldhearted. And she's fighting for control, even now I can feel her, buried deep down in my mind, her icy fingers tapping at the walls of my brain. And I'm terrified that some other part of me wants to let her out to have some fun."

- Killer Frost
