Frost, formerly known as Killer Frost and originally named Khione, is a major character in the Arrowverse TV series The Flash.
She was a meta-human criminal and a split personality of Dr. Caitlin Snow, before later becoming a vigilante/superheroine, member of Team Flash, and a sister figure for her, especially after the two physically separated. She is the arch-nemesis of Deathstorm.
She was portrayed by Danielle Panabaker, who also played her Earth-2 doppelganger and Ariel Eberhart in Grimm.
Overview[]
Caitlin Snow
Following Caitlin Snow's initial guest appearances in Arrow, she became a major character in its spin-off The Flash. In the fifth season, it is revealed that Catlin's father Thomas Snow experimented on her and himself in an attempt to cure their ALS genes, resulting in them both developing alternate personalities with cryokinetic powers. Caitlin's persona was originally named Khione, after the Greek goddess of snow. However, Khione was suppressed when Caitlin grow up.
In adulthood, Caitlin became a member of Central City's based S.T.A.R. Labs team alongside Cisco Ramon and "Harrison Wells", which supports Barry Allen in his journey as the Flash. After Barry altered the timeline while creating and undoing the "Flashpoint" during the third season, Caitlin unlock her cryokinetic abilities and her evil alternate personality now known as Killer Frost (named after her Earth-2 counterpart), both of which she attempted to hide from her friends.
Additionally, she develops a relationship with forensic scientist Julian Albert, while is advised by her mother, Dr. Carla Tannhauser, to not use her powers or her transformation as Killer Frost will become irreversible. So Caitlin began using power-dampening cuffs, and later a pendant made by Julian and Cisco Ramon. However, Catlin's abilities fully manifest after she sustains lethal injuries caused by Abra Kadabra and Albert removes her pendant so she can use her healing abilities to heal herself, triggering her transformation into Killer Frost.
She later joined Savitar as his enforcer and battled Team Flash, until Albert gives her a cure he developed. Frost subsequently betrays Savitar and helps Team Flash defeat him before leaving to rediscover herself. In the fourth season, Caitlin and Killer Frost develop a "Jekyll and Hyde"-esque relationship. While Caitlin became a bartender at O'Shaughnessy's, Frost joins Amunet Black's criminal organization. The two eventually learned how to switch between their personas at will. Furthermore, Killer Frost begins to show a more "heroic" side and agrees to use her powers to help Team Flash.
Later in the season, Caitlin discovers her powers and Killer Frost originated during her childhood and that she suppressed the memories. After her Father Thomas Show becomes Icicle, Caitlin and Killer Frost work together to save Thomas from his evil persona, with Killer Frost renaming herself as only "Frost". However, both Thomas and Icicle were killed by the second Cicada. In the sixth season, Caitlin experiments with giving Frost more time with their shared body and allowing her to live her own life. In the seventh season, they are separated after being exposed to Eva McCulloch's rays and decide to live separate lives as twin sisters.
In the eighth season, Frost transforms into Hellfrost and sacrifices herself to defeat the demonic entity known as Deathstorm. Having secretly taken a hair sample from Frost, Caitlin tries to resurrect her with Chillblaine's help by entering the Consciousness Resurrection Chamber, but the machine malfunctions, causing a new individual named Khione to emerge in the ninth season. Eventually, Khione becomes a nature goddess and returns Caitlin's body to her.
Personality[]

| ~ Killer Frost challenging Cicada. |
As Killer Frost, Caitlin became more vindictive, worried about her powers taking over. Having already met her Earth-2 self, who represented everything she didn't want to be (cold, double-sided, sadistic and unloved), she was worried even more that Team Flash would reject her if they knew about her post-Flashpoint powers. After becoming Killer Frost, her fears, insecurities and bitterness towards Barry for his creation of Flashpoint took over, thus making Killer Frost an entirely separate entity from the Caitlin that Team Flash knew and loved. She started mocking people more for their perceived weakness, mocking Cisco for fearing that he had to hurt her at all to save Barry, whom she regarded as selfish for tampering with time to give himself a happy ending and showing no regard for the consequences of his actions.
Caitlin was more fearful now that Killer Frost would take over completely, confiding in Julian Albert about her fear. As Killer Frost, however, she mocked Julian for thinking that there was a way to bring Caitlin back fully. She had a tendency to talk long sentences, going on rants about her superiority to Caitlin, whom she perceived as weak and pitiful. Desperate to show her loyalty to Savitar, she jumped at the chance to kill Tracy Brand, who would become a problem for Savitar in the future, but was insulted by the armored speedster for failing to kill her, mocking her decision to call herself "Killer Frost" when she hasn't actually killed anyone yet.
Caitlin now has better control of Killer Frost. Her Killer Frost side has become kinder but critical of some aspects of the Caitlin side, like her tendency to wear pink.
