In the DC Comics, Killer Frost needs heat to recharge her powers. That was why she always had her sights set on Firestorm. In the show, she's just known as Frost. Hope you like this post. I don't know why it was taken down earlier. Hopefully, it won't happen again. By the way, if KSC returns, he and I have been going over a new poll for Rogue One. I know it's late and that it already came out, but the poll is something we've been wanting to get around to. If he gets back and puts it up, I hope you vote. See you soon!
