After all with Captain Cold making the transition from rogue to Legend, our new cold draft will originate more in land.
Danielle Panabaker, who plays Snow on the show confirms the eventual transformation to Killer Frost.
From the beginning, I knew that Caitlin Snow becomes Killer Frost. And I can’t wait to suit up and duke it out with the boys!
She also went on to hint that there was something coming re season finale, which we suspect will be the beginning of said transformation.
In the comics, Killer Frost is as hardcore as her name suggest, a cold-blooded killer and villain making her rounds in Flash / Justice League publications. Weather we will see Panabaker’s version go off the good-guy reservation is yet to be seen or clarified.
