"If you knew me at all, you would know that I hate the name Caitlin. I'm Killer Frost!"

- Caitlin to Barry Allen

Caitlin Snow (died April 26, 2016), better known as Killer Frost, was a meta-human from Earth-2 with the ability to unleash frozen air from her hands. Caitlin was the wife of the late Ronnie Raymond. She was also a former ally of Zoom and a former reluctant ally of Team Flash.

Early life
Caitlin had a brother named Charlie who eventually died, leaving her mother "cold". She later went to medical school, but rarely studied and around 2013, she flunked out and had to move back in with her mother. Not long after, Caitlin was affected by Harrison Wells' S.T.A.R. Labs particle accelerator, giving her cryokinetic abilities.

Since then, Caitlin cut off all ties to her past life and began calling herself "Killer Frost", refusing to use her real name; even so much as hearing it made her angry. At one point in her life, Caitlin met and married Ronnie Raymond, a fellow meta-human criminal with pyrokinetic abilities. The two of them worked as Zoom's enforcers in Central City under the latter's right-hand man, Francisco Ramon/Reverb. Caitlin was also associated with Laurel Lance/Black Siren, a high-ranking lieutenant of Zoom.

The arrival of Earth-1 Flash
After Reverb sensed that his doppelgänger, along with other Earth-1 residents, had arrived on Earth-2, Caitlin and Ronnie searched for them. The two went to Jitterbugs and interrogated its patrons. Suddenly, Detective Iris West pulled out her gun and attempted to arrest them. As Caitlin moved to attack her, Earth-1 Barry Allen (disguised as his Earth-2 counterpart) attempted to reason with her, calling her Caitlin, to which she replied she no longer went by that name. Caitlin then fired icicles at Barry and Iris, who used a table as a shield. After Ronnie critically injured Joseph West, Caitlin and Ronnie were brought outside by Barry while Iris was distracted by her father, revealing he was the Flash. Caitlin attempted to kill the Flash with icicles but failed and told her husband to do so, becoming turned on wile watching their battle. The Flash used a helmet from a statue of "Jay Garrick" to redirect one of Ronnie's blasts towards Caitlin, injuring her. She was then taken away and tended to by Ronnie.

Later, Caitlin and Ronnie were approached by Iris, Detective Floyd Lawton, and Cisco Ramon/Vibe, Reverb's doppelgänger, but Caitlin forced them to stand down and drop their weapons. Iris expressed anger at the duo for her father's death, but they were unrepentant. When Reverb revealed himself, Caitlin was annoyed that he tried to get Cisco to join him instead of just turning him over to Zoom but Reverb silenced her with a threat. Suddenly, the Flash appeared and incapacitated Caitlin, Ronnie and Reverb. Iris wounded Caitlin with Cisco's special weapon, much to Ronnie's fury. Reverb and Ronnie eventually overpowered the Flash and began continuously hitting him. Caitlin urged them to cease fire, warning that Zoom wanted the Flash unharmed. Just then, Zoom arrived and quickly killed Ronnie and Reverb, much to Caitlin's horror. He then grabbed Caitlin by the throat but spared her, stating he was happy to see that she knew her place. After Zoom sped off with the Flash, Caitlin ran toward her husband's body but soon took off in despair.

Caitlin fled into the Woodlands to mourn Ronnie's death. The next day, she was approached by Iris, Harry, Cisco, and Earth-2 Barry, demanding to know where Zoom was in order to find the Flash and Harry's daughter, Jesse. Caitlin refused to say anything and instead tried to kill them and bring them to Zoom. Cisco eventually held her at gunpoint and Caitlin surrendered, but still refused to tell them where Zoom was. Cisco tried to reason with her, telling Caitlin of her Earth-1 counterpart and how distraught she was when her Ronnie died too. Upon hearing this, Caitlin was seemingly convinced to aid them and took the group to Zoom's lair at Ascension Cliffs, using her powers to create a walkway.

With some more persuasion from Cisco, Caitlin freed Jesse but was was unable to free the Flash since her powers couldn't penetrate the carbine glass, though he eventually managed to phase his way out on his own with help from Earth-2 Barry. Zoom then showed up, revealing Caitlin secretly called him. Zoom said that although he couldn't kill Earth-1 Barry or Harry, he could kill everyone else, starting with Jesse. However, Caitlin turned on Zoom for what happened to Ronnie and blasted him with her ice powers, holding him down long enough for everyone else to escape. Instead of being killed for her betrayal, Caitlin was imprisoned in Barry's carbine cell.

Death
After a couple months of imprisonment, Caitlin grew annoyed by her fellow inmate with an iron mask and wasn't sure why she was even still alive. It wasn't until Zoom brought her doppelgänger that Caitlin realized she was spared because she is the Earth-2 version of the woman he loves, and began plotting her escape. However, Caitlin always intended on killing her doppelgänger, because of both revenge on Zoom for Ronnie's death and the fact that he wouldn't need her anymore.

When Earth-1 Caitlin met her, Caitlin introduced herself and proposed a deal: if Earth-1 Caitlin freed her, she will help the latter get home to her Earth. While working, both Caitlins talked of their very different lives, but found common ground in their shared dislike for their mothers. Earth-1 Caitlin used electrical cables to heat up and weaken the carbine's molecular structure enough for her to smash the glass, allowing Caitlin to escape. As Earth-1 Caitlin wondered what to do about the man in the mask, Caitlin tried to kill her. Earth-1 Caitlin protested that they had a deal but Caitlin simply scoffed at her naiveté. When her doppelgänger tried to flee, Caitlin used her powers to create a sheet of ice, causing the former to slip and fall. She revealed why Zoom kept her alive, which wasn't necessary now that he had Earth-1 Caitlin. As Caitlin was about kill her Earth-1 counterpart with an icicle projectile, Zoom intervened and took it from mid-air. He brutally stabbed Caitlin in the stomach with the icicle, confirming that he doesn't need her anymore. Zoom dropped Caitlin's body to the ground, leaving her to die.

Legacy
In order to keep Black Siren occupied, Earth-1 Caitlin and Cisco dressed up as their Earth-2 doppelgängers and tried to convince her to join them, though Black Siren soon saw through the ruse.

Caitlin's death was avenged when Barry Allen helped ensure Zoom was imprisoned in the Speed Force by Time Wraiths. Earth-1 Caitlin later killed Zoom (who had become Black Flash) when the latter tried to kill Savitar.

After the dissolution of the Flashpoint timeline, Earth-1 Caitlin gained the same powers as her doppelgänger as well as a split personality and grew worried she would become evil. Eventually though, Earth-1 Caitlin was able to come to terms with her Killer Frost side, allowing them to coexist.

Personality
Unlike her Earth-1 counterpart, who is compassionate and loving, Caitlin was cold, cruel, sadistic, ruthless, arrogant and immoral with no guilt or remorse for the deeds she committed as Zoom's enforcer. The only person Caitlin truly cared for was her husband, Ronnie Raymond; the two were deeply in love and always protected each other. Caitlin has a fairly uninhibited personality, being public with her affections for her husband, even expressing how she gets turned on when witnessing him in battle. She seems to be slightly vain as well, taking great pride in her looks and wearing form-fitting clothing to show off her body, even poking fun at Earth-1 Caitlin's more modest clothing. Caitlin has a dry, mocking, sadistic sense of humor, which she often expresses while attacking and killing her targets.

Caitlin's attitude and criminal nature is implied to have partially stemmed from her difficult past, with the death of her brother and subsequent estrangement from her mother. This is reflected in how Caitlin only refers to herself as Killer Frost, hating even the sound of her real name.

Underneath her arrogance, Caitlin was openly terrified of Zoom; unlike Ronnie and Francisco Ramon, she knew better than to disobey his orders, knowing the latter would kill her for trying to harm the Flash.

After Zoom murdered Ronnie, Caitlin was devastated and heartbroken. She desired revenge on Zoom, being willing to briefly ally with Team Flash to help free the Flash and Jesse Wells, the speedster's prisoners, regardless of the potential risks. However, Caitlin's desire for revenge soon grew beyond reason; she tried to murder her doppelgänger, who Zoom loved, as revenge for what happened to her husband despite the fact that Earth-1 Caitlin helped the former escape from her cell.

Powers

 * Meta-human physiology: After Caitlin was struck by the energy of the Particle Accelerator explosion on Earth-2, this altered her DNA and supercharged her cells, augmenting her physiology to properly access her newfound powers.
 * Transformation: Upon receiving her powers, Caitlin's hair turned white, her lips blue and her skin pale.
 * Cryokinesis: Caitlin had the ability to freeze the air around her into ice, allowing her to create pathways and entire walls of ice. Caitlin could freeze virtually any substance by a single touch, allowing it to easily shatter, including people. She even temporarily held the speedster Zoom hostage by encasing him in ice.
 * Freezing kiss: Caitlin was able to freeze an entire human by kissing him.
 * Ice spike projection: Caitlin was able to generate icicles, which she used as weapons against her opponents.
 * Cold immunity: Caitlin is immune to her own powers.
 * Heat immunity: Caitlin's powers allow her to easily withstand intense heat temperatures. She was able to kiss and touch her husband, Ronnie Raymond, while he was Deathstorm.

Abilities

 * High-level intellect/Expert tactician: As an enforcer for Zoom, Caitlin was very intelligent and a capable tactician.
 * Medical knowledge: Despite failing medical school, Caitlin was shown to have some knowledge in medicine. For example, she deduced that heating carbine with electricity would weaken its molecular structure.

Trivia

 * Unlike her Earth-1 counterpart, Caitlin is more willing to show off her body. However, after Earth-1 Caitlin got powers, her Killer Frost side changed clothes in front of Iris, Felicity and Cecille, implying that it's only the Frost persona in both versions of Caitlin who doesn't like to dress modestly.
 * Apparently, Caitlin Snow doesn't exist on Supergirl's Earth. However, as shown by Jay Garrick being Henry Allen from Earth-3, same versions of people do not necessarily have the same name.
 * Caitlin and Ronnie's song is "My Funny Valentine."

Behind the scenes

 * Killer Frost is an alias used by three different female metahuman super-villains, all of whom were enemies of Firestorm in the main DC Comics continuity. In the pre-Crisis on Infinite Earths timeline, Crystal Frost (introduced in Firestorm: The Nuclear Man #3, in June 1978) was a college student in love with Martin Stein who became the first Killer Frost after a freak accident which imbued her with the power to absorb heat and generate cold. After her death, a new Killer Frost debuted as Dr. Louise Lincoln (in Firestorm #21, in March 1984) a friend of Crystal's who gains the latter's powers through the same means in order to avenge her death. This incarnation of the character made several appearances up until the New 52 relaunch, having been a member of the Injustice League, Secret Society, Suicide Squad and an independent contractor. During the Forever Evil crossover-event of the New 52 relaunch, Caitlin Snow was introduced as the latest incarnation of the Killer Frost persona (as Caitlin Snow in The Fury of Firestorm: The Nuclear Man #19, in June 2013, and as Killer Frost in Justice League of America #7.2, in September of the same year). This character is a S.T.A.R. Labs scientist in the field of thermodynamics, working in the Arctic.
 * The Arrowverse version of Killer Frost, although identified as Caitlin Snow, also shares the Crystal Frost version's affection towards a member of the Firestorm/Deathstorm entity, in this case Ronnie Raymond.
 * When confronting Killer Frost in the forest after finding her, Cisco called her "Elsa", referencing a character from Disney's film Frozen, due to her blonde hair and ice-manipulation powers.
