Taking down the Flash just became a family affair. On The CW's hit TV series, "The Flash," Captain Cold (Wentworth Miller) and his partner-in-crime, Heat Wave (Dominic Purcell), tussled with the scarlet speedster and were defeated. The two would have ended up in the slammer if not for the timely rescue by Cold's younger sister, Lisa Snart, who goes by the codename Golden Glider and is played on the series by "The Tomorrow People" veteran Peyton List.

Introduced in 1977's "Flash" #250 from DC Comics, Lisa was an Olympics-level figure skater whose villainous boyfriend The Top died during a confrontation with the Flash. Vowing revenge, she designed an arsenal of jewel-themed weapons and special ice skates that created their own ice flow. The show has put its own spin on the character and in the episode "Rogue Time," Golden Glider, Captain Gold and Heat Wave return to Central City to wreak havoc and destroy the Flash.

Ahead of tonight's episode, List spoke to CBR News about modernizing the Golden Glider, sibling squabbles, a revamped costume, possible future appearances and facing off against Firestorm.

CBR News: You previously appeared as Lucy Lane on "Smallville," another DC series that aired on The CW. What's been exciting about stepping back into the DC Universe and the realm of superheroes?

Peyton List: It's really fun to go back into that universe because there are so many different explorations of it. There are so many different shows and movies and formats. It's fun to try different takes. I don't think you get many opportunities to be a different person in that world. That's kind of a treat.

For people who are unfamiliar with the "Flash" comic books, who is Lisa Snart?

Obviously, Lisa Snart has been explored much more in the comic book world than she has been on "The Flash" so far. She is Leonard Snart [AKA Captain Cold]'s little sister. She is also known as the Golden Glider. As we meet her in "The Flash," they are going to break you in as they do with all the characters. They don't just usually jump right in with who they become. They tell the story and how they grew into that role. When we meet her, she's a bit of a mysterious figure at first. As the story progresses, we'll get to know more about her.

Do they touch on her history with the Top and his death?

Maybe they will. I haven't learned that so far.

That death was a big motivating factor for Lisa's criminal behavior in the comic books. What leads her to team up with her brother Captain Cold and take on the Flash?

We already know that she's teamed up with her brother. We got an itty-bitty, tiny glimpse of her helping him escape from that truck. She's already on their side and working with them, or for them. We know there is some sort of history with her brother. There is already an established back story with them. We'll come to find out exactly how their relationship works. As of right now, she's the third musketeer.

Lisa and Leonard always bickered in the comics. How would you describe their relationship on the small screen?

They are very much siblings. They bicker because they are siblings, maybe more so than they would with anyone else. There's also a loyalty underneath it because they are brother and sister. It's a fun dynamic. The idea of them bickering while in the middle of battle, or in front of a mutual enemy, is a fun thing to watch.

Does Lisa feel she needs to prove something to Leonard?

When you have an older brother like Leonard Snart, you are always going to be trying to impress or make a name for yourself or prove your worth. It's like having a super-talented, older sibling. You are always like, "Look at me. I can do it too!" There's definitely an element of that in their relationship.

The original Golden Glider costume is dated. How was it redesigned for the show?

They modernized it and it also fits into the world of how they are telling the story of "The Flash." It's slightly toned down, if that's the right word. Lisa isn't going to walk down the street in what we see in the comics. That would draw a little too much attention. It is still in the comic book universe of being flashier than you might see in everyday life, but she can blend if she needs to. A lot of the characters are that way, so you can't just spot them a mile away, which works out well for the villains. How else would they get away with anything if you can see them coming? Her outfit is a bit more current. Trying to get around on ice skates would be a little bit difficult in this show. She's actually wearing normal footwear.

Flash has proven he can outrun and outmaneuver Captain Cold and Heat Wave. How does Golden Glider throw him off balance?

She's a surprise element. Lisa is something that the Flash does not see coming. It's great when you have these villains adapting. Captain Cold is going, "Okay, what I've been using isn't working. I need to find another way to outsmart him by bringing in another person with another talent." It ups the ante a little bit more. The element of surprise, and with Lisa coming out of nowhere, is to Captain Cold's advantage.

What does Lisa's special gun do?

I don't think I have an affinity for cold the way my brother does. She prefers gold. When her brother and his partner have guns, she wants one too. You have to be one of the guys. Lisa gets a gun personalized for her and then gets to have all kinds of fun with it.

This isn't your first rodeo when it comes to super powers. How did "The Tomorrow People" prepare you for this role on "The Flash?"

As an actor, having done "The Tomorrow People" made it so much easier to get back into that world, to understand how to work with the special effects and how to do things in a way where you're going, "Okay, I'm going to do this, but when they put it through post, it's going to look super cool." Having done "The Tomorrow People," you trust the process more. It's not quite as foreign.

How was it sharing scenes with Wentworth Miller and Dominic Purcell?

It was extremely intimidating at first. I tried to play it cool, but once I got on set with them, it was such a blast. They have very different personalities and have different approaches to their characters and how they work, but they are so unbelievably talented. It's such a pleasure to join in on the team. I couldn't believe when I got this role that I would be working with them. I was a huge "Prison Break" fan, so it was like any fan's dream. You go to sleep and you wake up and you are working with them. I had a great time. They are really nice people to work with, so it makes everything that much more fun.

There's been all this talk about the Flash's rogues banding together. Do you feel the door has been left open for the Golden Glider's return?

It's still a mystery to me, which is sort of exciting. I've done a couple of jobs where they will lay it out for you, like what's going to happen down the road, so you can hint at it along the way. Then I've done jobs where you are completely in the dark. You're like the audience, where you're figuring out as you are going along. With a show like this, it's a bit of both. You have the comics and you know essentially what could happen. But, then they also have their liberties in their storytelling. You can guess at what's going to happen, but at the same time, I am excited to see the next step. Am I coming back? What's going to happen next and how will the story play out?

Robbie Amell co-starred with you on "The Tomorrow People" and currently recurs on "The Flash" as Firestorm. Would you like to see Golden Glider and Firestorm clash? Could you take Robbie?

It's been such a bizarre and wonderful experience to watch Robbie on the show because his character is so different and he's doing such a great job with it. It's exciting any time you see someone you've worked with in something else. But, to be in the same world again, and as completely different characters, is awesome and that would be such a blast to do. But, yeah, I have a little advantage. I know Robbie's skills. I'm sure I could take him.

"The Flash" airs Tuesdays at 8pm on The CW.
