We're dying to meet the coolest chick in Central City!

Fans of The Flash had a mini freak out during Barry's (Grant Gustin) glimpse into the future in the season one finale thanks to a quick, but memorable cameo by Killer Frost -- aka the villain that Caitlin Snow is destined to become.

With the season two premiere only two weeks away, we called up star Danielle Panabaker to get the exclusive scoop on Caitlin's icy journey, her favorite Flash villains, and what it took to create that killer costume!

With The Flash: The Complete First Season out on DVD and Blu-ray today, ETonline snagged your exclusive sneak peek at one of the most adrenaline-pumping bonus features: a look back at the best villains!

So, of course, we had to ask Panabaker which Central City bad guy was her favorite to see on screen. "I really loved Captain Cold," she gushed. "Because he's not your typical villain. He doesn’t have superpowers like a lot of the other metahumans do but he's one of my favorites."

Is anyone else loving the fact that Panabaker chose a fellow cold-lover as her favorite villain? Looking ahead to Caitlin's future, the actress stressed that fans should keep their cool when it comes the timing of Killer Frosts' debut.

"I think the thing to keep in mind is when Barry ran through time at the end of season one, he saw a glimpse into the future and different versions of the future," she explained. "There's no telling how far into the future it is, so I can't say with any amount of confidence whether or not that's happening this year, but just know that personally I'm so excited about it. I cannot wait to get here."

And as for that gorgeous costume, Panabaker revealed that her villain makeover was meticulously crafted over several months. "There was actually a sort of jumpsuit idea that we ultimately scrapped because it wasn't quite right," the actress admitted.

"That wig was quite the evolution," she said. "It started as a little pixie wig but we -- myself, Sarah [Koppes] who does our hair and Andrew Kreisberg our executive producer -- all collaborated we definitely felt that it should be longer."

Panabaker continued, "Same thing with the makeup. There were some suggestion that the lips should be white and we tried that. Believe me, we tried all of these different variations before we ultimately settled on the look that you saw, which was so cool and those contacts were beautiful."
