The Flash has added yet another DC Comics character for Season 1, with Peyton List signing on to play Lisa Snart in The CW show's 16th episode, entitled "Rogue Time". Lisa Snart is the sister of Wentworth Miller's Leonard Snart, a.k.a. Captain Cold. In the DC Comics, Lisa Snart eventually became one of the Rogues with her brother, transforming into the villainous character known as The Golden Glider.

While Leonard is a cold and calculating villain, Lisa is much more of a wild card, determined to show Leonard that she has what it takes to be one of the Rogues. Lisa is described as "sly, charming, and even a little sadistic," who isn't afraid to use her sexuality to get what she wants. Her alluring nature will reportedly "put her on a crash course" with S.T.A.R. Labs employee Cisco Ramon (Carlos Valdes).

It remains to be seen when fans will see the full formation of the Rogues super-villain group, which also includes Dominic Purcell's Heat Wave. Both Captain Cold and Heat Wave are expected to expand their nefarious group when The Flash returns Tuesday, January 20 at 8 PM ET with the aptly-titled "Revenge of the Rogues". In case you missed it last week, you can check out Captain Cold and Heat Wave's return in the midseason premiere trailer.
