'The Flash' Recruits 'The Tomorrow People' Alum Peyton List
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).
Leonard Snart, who Cisco nicknamed Captain Cold, quickly became a thorn in The Flash's (Grant Gustin) side, when he made his debut earlier in the season. While not a meta-human, Leonard obtained some technology (a special gun that freezes things), originally built by Cisco, which helps aid him in his criminal pursuits in Central City. He is expected to expand his associations (The Rogues), hooking up with Heat Wave. She's also known as "The Golden Glider",and girlfriend of another rogue "The Top".
