The Flash Season 2: The Caitlin Snow to Killer Frost Transformation

Danielle Panabaker has melted fans hearts as Caitlin Snow, but she will freeze them as Killer Frost on The Flash season 2.

This article contains what are probably pretty minor The Flash season 2 spoilers, but just in case, now you know…


The final, official, fully evil Killer Frost look for The Flash season 2 has finally been revealed. Ms. Snow will transform into Killer Frost on “Welcome to Earth-2” which airs on Tuesday, February 9th. It’s not quite the heel turn that we were expecting from her character (at least, not yet), as The Flash is instead going the evil doppleganger route.

And here’s the official synopsis:

BARRY VISITS EARTH-2 – Barry (Grant Gustin), Wells (Tom Cavanagh) and Cisco (Carlos Valdes) journey to Earth-2 to rescue Wells’ daughter, Jesse (guest star) from Zoom.  Barry is stunned when he runs into Earth-2 Iris (Candice Patton) and Joe (Jesse L. Martin), but nothing prepares him for meeting Killer Frost (Danielle Panabaker) and Deathstorm (guest star Robbie Amell). Meanwhile, back on Earth-1, Jay (guest star Teddy Sears) has to take over the Flash’s responsibilities when a meta-human nicknamed Geomancer (guest star Adam Stafford) attacks Central City.  Millicent Shelton directed the episode written by Greg Berlanti & Andrew Kreisberg and Katherine Walczak (#213).

If you aren’t completely charmed by Danielle Panabaker as Caitlin Snow on The Flash, well, you probably just aren’t a fan of that show in the first place. While it’s easy to get caught up in her banter with the rest of the cast, her romance with Ronnie “Firestorm” Raymond, and even the occasional (well, OK…once) bit of karaoke, since Caitlin’s name was first announced, fans have had two words on the brain: Killer Frost. We sat down at an SDCC roundtable with Ms. Panabaker to discuss her transformation into Killer Frost.

The cold-wielding supervillain has been kicking around the DC Comics universe since 1978, and she’s primarily been known as a Firestorm antagonist. Earlier incarnations bore names like “Crystal Frost” and “Louise Lincoln” before Caitlin Snow came around in 2013 as part of the DC New 52. But the connection to Firestorm has always been a strong one, so the decision of The Flash producers to pair Caitlin up with Ronnie Raymond helped tie things to the character’s larger history.

We got the briefest glimpse of Danielle as Killer Frost in The Flash season one finale, and even though she admits “that was a little bit of a tease,” it sounds like that is pretty close to Killer Frost’s final look.

“It was exciting as an actor because it’s a truly transformative look,” she said. “Starting with the wig. When we first started doing ideas for Killer Frost, the first wig was a pixie, and we tried that on and we all collectively felt that her hair should be longer.” 

Of course, the transformation doesn’t end with the hair. “The makeup was the same thing. We tried lots of different looks. At one point they wanted to see my lips really whited out, but I felt strongly that we should have a navy lip. We tried it all.”

Considering that Killer Frost was on screen for a matter of seconds in the finale, considerable thought was put into this look, probably to avoid contradiction when they introduce her properly in future episodes. “The actual first costume Sarah (Koppes) built was a one-piece, like a jumpsuit, it was very Catwoman-esque. Then one week I showed up for a fitting and she said, ‘I scrapped it, we’re starting from scratch. It needs to be sexier.’ And I said ok, great!”

I asked her if there was any fight training in her future, since she’ll have to take on Flash and probably Firestorm and perhaps others, as well. “I hope so! I’m desperate to get out there and duke it out with the boys. Not when it’s raining, but any other time.”

It still doesn’t sound like they’ll be rushing into the big change, though. “Obviously, I’m extremely enthusiastic about becoming Killer Frost, and I want it to happen like, yesterday, but it’s going to be exciting to see that journey and how it happens.”

The Flash season 2 premieres on October 8th.
