Captain Cold (Wentworth Miller) has a sister and she's ready to be another thorn in The Flash's side as The Tomorrow People's Peyton List will be joining the Rogue's Gallery as Lisa Snart aka The Golden Glider on the hit CW show.
While Leonard is cold and calculating, Lisa is a wild child and anxious to prove to her older brother she’s got what it takes to be in his criminal gang. She is sly, charming, and even a little sadistic. She's also not afraid to use her sexuality to get what she wants, which will put her on a collision course with S.T.A.R. Labs employee and friend of The Flash -- Cisco Ramon (Carlos Valdes).Armed with Cisco's freeze gun, Captain Cold proved to be a formidable foe for Barry when he appeared earlier in the season. Now gathering a gang of his own with Heat Wave (fellow Prison Break co-star Dominic Purcell) and his little sister the second half of season one is sure to be explosive.
List appeared on producer Greg Berlanti's The Tomorrow People on CW before it was cancelled after one season. She's also best known for being Mrs. Roger Sterling on Mad Men for five seasons. This also reunites her with her TTP co-star Robbie Amell who plays Firestorm on The Flash. She'll make her first appearance in episode 16 of next year.
The Flash returns with new episodes on January 20 on The CW.
