Caitlin Snow

About:
Dr. Caitlin "Cait" Snow, also known as Killer Frost, is a bio-engineer at S.T.A.R. Labs and an original member of Team Flash. Caitlin helps The Flash from in S.T.A.R. Labs via wireless communication. She was recruited into the S.T.A.R. Labs team by Eobard Thawne, posing as Harrison Wells. Her, then, fiancé Ronnie Raymond was also recruited by him.

After Barry created and tried to restore the Flashpoint Timeline, he slightly altered the official timeline. In the altered timeline Caitlin did get affected by the particle accelerator explosion and gets the powers of her Earth-2 doppelgänger, Killer Frost. She didn't get affected by any dark matter in the previous timeline.

She then called herself Killer Frost too. Killer Frost wasn't really Caitlin but it was more like a second personality. Caitlin first needed to use meta-human dampeners to surpress Killer Frost from taking over but later she got control over it. Now Caitlin turns into Killer Frost whenever she gets scared or angry.

During the time Killer Frost was mostly in charge over Caitlin she worked for Amunet Black for a while but she later was recruited by Cisco Ramon into Team Flash again because of Clifford DeVoe's threats during Barry's absence. She then helped Team Flash bringing back Barry from the Speed Force.
