Some of you only think of me as the criminal I used to be. Back then, I was only interested in protecting myself. But, then, I found someone else worth protecting. And protecting that person led me to protecting a whole city. And slowly I changed. I learned how… I learned how to be selfless instead of selfish. I learned that I’m my best self when I’m protecting other people.

[ 7 ] She was kept at bay for a while after Caitlin used power-dampening cuffs to stop her powers, and subsequently her other persona, from emerging. After using her powers to save Barry Allen from Savitar, Killer Frost ‘s personality came to the fore, but Caitlin went to find Alchemy to try to get rid of Killer Frost. Caitlin used her ice powers to torture one of Alchemy ‘s acolytes to try to find him, but left him frozen barely before CCPD arrived. Caitlin then kidnapped Julian Albert to make him run a search algorithm to find Alchemy, hoping Alchemy would take away her ice powers, and finally located another penis of his cult. julian managed to call the police, and the Flash arrived to try to talk Caitlin out of using her ice powers. Caitlin stabbed him in the stage and escaped to find Craig, the cult member julian establish. Caitlin threatened his family, and he told her that he did n’t know where Alchemy was or who he was, but that he had shown them the future where she was Killer Frost permanently.

She woke up in the pipeline and tried to convince Team Flash she was back to normal, though they were unconvinced. After Wally West was cut out of the cocoon he was trapped in by Alchemy, Barry was forced to go to the grapevine to talk some sense into Caitlin. He let her out of her cell and asked her to kill him but, ineffective to hurt her acquaintance, Caitlin managed to avoid killing Barry. [ 8 ] In early 2017, Caitlin was given a necklace by julian that dampens her powers and besides collects solar energy to charge it to ensure that it continues to work by rights, thereby keeping Killer Frost at bay. [ 9 ] After Iris West was touched by Clive Yorkin, who had the office to disintegrate anything he touched, she was lento dying. Caitlin was then forced into using her powers to slow down and stop the dissolution. however, in the middle of this, Killer Frost concisely took restraint and stopped saving Iris. She even taunted julian, who ended up talking her out of it and allowed Caitlin to regain operate. [ 10 ]

Joining Savitar

Labs was attacked by Abra Kadabra, Caitlin was critically injured by shrapnel and helped julian perform her operation. however, she late began dying from a capture. julian, Cisco, and H.R. attempted to resuscitate her, to no avail. In an attempt to bring her back to life, Julian ripped off Caitlin ‘s necklace and her powers caused her wind to heal, but once she opened her eyes, it was Killer Frost who emerged. She knocked everyone back with a huge wave of ice and emerged from the icy smoke with her haircloth fully white. [ 11 ] She then attempted to kill them with beams of ice rink from her hands, even knocking Cisco and H.R. by smashing a window they were behind. julian then attempted to grab her necklace and put it back on Caitlin ‘s neck, only for Frost to destroy it with another ice stroke. He told her that he cared for her, and she used this to her advantage, telling him to kiss her so she could freeze his lead. however, before they could meet each other ‘s lips, Cisco knocked her back over a table and into a wall with a vibration fire. When the three men ran out of the room, Frost followed and found them attempting to hide in the pipeline. equitable when she was about to kill them, Barry sped in and knocked her into a wall and told Caitlin that she could fight what was happening to her.

When she arrived, Barry, Cisco and H.R. were already there trying to get her out. frost entered by freezing and smashing a glass doorway and sending an icicle right for Tracy. however, before she could be impaled, Barry moved her out of the way with his extremely accelerate and told H.R. to get her out. He was then knocked to the grind by Frost ‘s methamphetamine beam. As she was about to run after H.R. and Tracy, Cisco got in her way, she rubbed the fact that she was in full Killer Frost now in his face and shot him with an ice shine, knocking him over a rejoinder and onto the floor. This was when Barry got up and used a flamethrower and his accelerate to launch burn at her, causing her to retreat. When she reported spinal column to Savitar, he accused her of letting Barry and Cisco go on determination and told her all she had to do to be a idol like him is kill Tracy. She belated showed up outside Jitters and was about to attack Tracy and H.R. again until Barry, Julian and Cisco showed up, allowing H.R. and Tracy to flee the picture. Frost chased after them by creating a path of ice that flew through the air out with Barry chasing after her, attempting to get her to return to Jitters so Cisco could shoot her down. however, when she reached Jitters, Cisco could n’t shoot her down as he placid saw her as his ally, and this gave her the opportunity to shoot a beam of frost at him, then Barry was forced to run in front of him and take the blast, sending him down a fledge of stairs. Killer Frost then reached the ground again and walked over to Barry, taunting him. She then stabbed him in the branch again, stating “ scar weave is much more sensitive than regular tissue ” .

Later, Team Flash arrived in a warehouse that Cecile was being kept in and Frost appeared out of the shadows and taunted tracy about killing her and asking them to hand Tracy over in return for Cecile. Barry then attempted to talk to get Caitlin to snap out of it and let Cecile go but to no avail, she then reveals that she knows Cisco is hiding up in the rafters and sets off a bombard forcing him to cursorily open a breach and land across the warehouse, knocked out and in a stack of boxes. Frost then went to shoot Joe with an methamphetamine beam only for Barry to run in the direction and get frozen on the ground. Before Frost can do anything else, Cisco shot her in the back with a vibration gust. however, she quickly gets back up and the two shoot their respective powers at each other. At first, it seemed Frost was winning until Cisco mustered adequate ability to knock her back into a wall, knocking her out. Savitar then appeared and sped her out of the warehouse. [ 13 ]

Regaining Savitar ‘s memory

Since Savitar was a time end of Barry, he remembered everything that Barry did, so Team Flash wiped Barry ‘s mind to prevent Savitar from knowing their plan. After they did this, Killer Frost wanted their plan to speed up and approached Savitar ‘s kneeling armor in decree to get to work merely for him to abruptly stand and hold Frost against a wall by her throat. She asks what he ‘s doing but he entirely asks the questions “ who are you ? ” and “ who am I ? ”. She then realizes what ‘s wrong and travels to S.T.A.R. Labs to get help from Team Flash. When Cisco, Wally and Julian restitution to the Cortex, Frost was waiting for them. wally attempted to speed towards her but realized that he had lost his speed and she tells them that she knows why. The three were discussing with each early to see if they should trust her or not until Barry, Iris and Joe walked in, wondering why they looked sol concern when Killer Frost walked out from Caitlin ‘s previous lab, causing Joe to pull his grease-gun on her. Everyone told him to stand down and he did sol. Barry, still in his amnesia like country, asked if Frost was some kind of supervillain, causing her to look at him with an “ obviously ” front on her front. He then left the room, which left Frost with erstwhile allies of Caitlin. She explains that what Barry remembers, Savitar remembers, and the team could just teach Barry everything and beat Savitar. however, there were lots of villains in Central City and no Flash to stop them at all. She then convinced them all that they needed to work with her to bring back Barry ‘s memories. Cisco and Julian worked with Frost and while they worked, Cisco attempted to remind her of all of the memories they had working on the particle accelerator. It seemed to get through to Caitlin but Frost cursorily took over again. late, the three ran second to the cerebral cortex and turned on the television, merely to see that a build had been set ablaze by an ill-famed arsonist.

They tried to tell her that she was their ally and could be again with Julian besides saying that he loves her, but she replied that she never loved any of them and entered the elevator. Once the elevator started its lineage, Caitlin briefly took over merely for Frost to bury her again .

Final fight

Killer Frost approached Savitar to ask what he was working on in his suit and he replied that his suit was damaged during his competitiveness with Barry. Frost then asked if they were a team, referring to them both as “ Barry and Caitlin ”. He looked up and replied that he was n’t Barry and she was n’t Caitlin. She then asked if Savitar was in truth going to kill Iris after all of the memories he shared with her. He asked if she is having second gear thoughts about their design and she only shook her head, visibly scared. Memories begin to flood into Savitar ‘s head and she asked what he saw. He explains that Barry went back in time to ask for Leonard Snart ‘s aid to retrieve the power generator for their weapon to use against Savitar. Frost asked if she should stop them but Savitar precisely said that it does n’t matter. Later, Cisco got a vibration of Killer Frost in a afforest, waiting for him to come fight her. Cisco then arrived at her location and the two began to fight merely for Frost to overpower Cisco, flooring him and giving her a chance to kill him. [ 14 ] however, before she could finish Cisco off, Savitar sped in and commanded her to spare his life sentence. Confused, she asked why he needed to live. He explained that Iris had survived because H.R. had taken her rate and died, and that they needed Cisco to build something for them. H.R. died because Killer Frost took H.R. back to Savitar to be murdered when H.R. was disguised as Iris West in an escape undertake. The three then speed back to Savitar ‘s lair. Savitar explained to Cisco that he needed to convert the Speed Force bazooka into a quantum splicer in regulate for him to survive without the time paradox catching up on him. In club to make Cisco begin working, Savitar besides threatened Frost ‘s life, knowing that he would never get over the death of his best ally. After Savitar had left, Frost asked Cisco if he had finished the splicer and he nodded. He then attempted to tell her that if she continued to work with Savitar he would finally kill her after he did n’t need her abilities anymore, but she disagreed and thought they would constantly work together. mighty afterwards, Savitar returned to his lair. He asks if everything is done and Cisco explained that it is. Frost then began to raise her hands and Cisco repeated that Savitar would kill her but she does n’t listen and fires an icicle straight at his chest only for it to be stopped by a gap. The two villains looked traumatize until Cisco ‘s girlfriend, Gypsy, leaps into the lair through another rupture and pulls Cisco into another matchless. Killer Frost asks Savitar if he cared that they escaped and he replied that it did n’t matter since the splicer was quick. The two arrived at the outskirts of a afforest and began to use the splicer to make sure Savitar would live, but they are stopped by Jay Garrick, who escaped from the Speed Force. They then turned to see that all of Team Flash had arrived. Frost told Savitar to go whilst she fought Cisco and Gypsy. She was promptly thrown to the anchor which gave Cisco the chance to kill her but he refused and gave her a cure that was made by Caitlin ‘s mother and julian. She seemed very hesitant but once Savitar grabbed Cisco and was about to kill him, Caitlin Snow managed to take over Killer Frost and buried her rather and she saved Cisco ‘s life. Killer Frost and Caitlin never apologized to Cisco for her attempts to murder him. After Frost ‘s defeat, Savitar was besides erased from being and Caitlin left soon after. [ 15 ]

When Caitlin was working her shift in Amunet ‘s cabaret, she was approached by Cisco who asked her to rejoin the team. She ended up accepting his offer and helped them get Barry out of the speed violence. When she returned to the clubhouse to quit the condemnable constitution she confronted Norvock and told him about her decisiveness. When he grabbed her by the arm, it caused Killer Frost to reemerge and she managed to bash his head on a nearby machine. She then threatened him and walked out of the club.

He attacks everyone at the table and when Cecile, Felicity and Iris are all down, Killer Frost emerged and transformed in front of everyone ‘s eyes. She then shot a air of ice at Norvock which knocked him through a window. The women then return to S.T.A.R.

Frost then explains that she is like a split personality and while Caitlin sleeps she is the one in control. She besides retrieves her new suit from a large black bag and leaves to go and find Amunet Black. When she reached Amunet ‘s club, Frost threatens her bodyguards to get past them and is greeted by Amunet herself.

She then asked Killer Frost if she wanted to rejoin her and they could run Central City together as gods. Frost, however, refused Amunet ‘s offer and the two prepared themselves to fight each other until Iris ran in between them and managed to get Killer Frost out of there and back to S.T.A.R. Labs .
The girls asked Frost how she knew Amunet and she explains that she and Caitlin both worked for her and actually ranked very senior high school in her criminal organization. She besides admitted that she ‘d tortured Amunet ‘s enemies by freezing their fingers and toes off. Frost then told them that she planned to retreat to another earth to escape Amunet and live her own life how she wanted, without Caitlin. Iris then attempted to talk Killer Frost out of leaving and told her that she and Caitlin could live in concert as one. however, Frost entirely threatened to freeze her hand off and leaves the room to go contend Amunet. The two women meet under a bridge. Frost did n’t expect to see Amunet herself and was caught off guard when she launched a big piece of metal into Frost ‘s shoulder. She then attempted to recover by launching frost blasts at Amunet but she only deflected them with a metallic element shield and launched two more large pieces of alloy that floored Killer Frost .
Amunet then picked her up by the collar of her jacket and started to throw punches that made Frost retreat second into Caitlin ‘s mind and allowed Caitlin to retake control of her torso. Caitlin then returns to S.T.A.R. Labs and decided to stay while Iris, Felicity and Cecile fought Amunet. however, when things went south and Felicity and Iris were captured, Caitlin appeared in front of Amunet and her henchmen and allowed Killer Frost to take control. As Iris and Felicity ran behind Frost, Amunet ordered her goons to kill them but before any of the bullets could hit them, Frost made a giant igloo-like ice dome-shield to protect them. Iris then told Cecile to turn on a giant attraction so Amunet could n’t use her powers. She did as Frost had instructed, and rendered Amunet powerless. Frost then formed an icicle, ready to stab and kill Amunet until Iris managed to talk her out of it and they all return to the lab. Despite all Iris did to help her, Killler Frost never apologized to Iris for Killer Frost working with Savitar to murder Iris. Killer Frost never apologized to Cecile for threatening to murder her. late, the boys from Barry ‘s knight bachelor party arrived back in the lab to find Killer Frost waiting for them in the cerebral cortex.

After the Nazis are defeated, Barry, Iris, Felicity, and Oliver Queen all get married and the heroes return to their respective Earths and times. [ 22 ]

Battling The thinker

After Barry was wrongfully accused of murdering Clifford DeVoe, he was in his trial when the city was threatened by a meta-human Cisco nicknamed Fallout. Killer Frost was needed to cool him down or else the stallion city would be nuked by him. Cisco and Harry Wells had to traumatize Caitlin in order to get Killer Frost to emerge and when she did, she and Cisco were breached to Fallout ‘s placement. At first, Frost seemed to have won by simply freezing Fallout, but he broke out of the ice and stroke Frost with a beam of department of energy, sending her flying back into a bus diaphragm and besides knocking her unconscious mind. fallout was then defeated by Barry and Cisco. [ 23 ] Frost helped Vibe when they were sneaking into Trickster and Prank ‘s hideout. When they both saw what appeared to be hostages, they ran towards and began to set them barren until they heard a make noise behind them and saw a group of Beebo toys that Frost freeze and shattered with her powers. When they turned back to the hostages they revealed themselves as Trickster and Prank in disguise and put power-dampening cuffs on Frost and Vibe, causing Killer Frost to disappear and Caitlin to reemerge. Both Caitlin and Cisco were then saved by the newest member of Team Flash, Ralph Dibny. [ 24 ] When Ralph began to doubt himself, Caitlin went to his office to try and give him a pep talk but when he would n’t listen she let Killer Frost out and she talked to him. He told her the trouble was that he believed all of his friends would leave him as his friends in the past have. Frost then told him that the people in Team Flash never gave up on her and that they would never give up on him, which lifted his spirits. Frost lied by not telling Ralph about all the attempts she made to murder members of team Flash, including the fact that she was an accessory to H.R. Wells ‘ murder when she took him to Savitar knowing he ‘d be murdered. He flush called her “ crisp Oprah ”. When Barry Allen attempted to escape from prison because of Amunet who was looking for meta-humans to buy and recruit into her organization, Vibe and Killer Frost breached into Iron Heights and asked him to come back to S.T.A.R. Labs with them, but he refused, not wanting to become a fleeting. Clifford DeVoe was besides alive and took over the body of former Team Flash enemy, Becky Sharpe. [ 25 ] When the team heard about an attack on the CCPD at an airfield, Killer Frost, Vibe, The Flash, and Jesse Quick traveled there to help them. Once they arrived they were able to cursorily take out the henchmen and were ready to take out their party boss, Veronica Dale, until she revealed that she was approximately to activate a microwave. however, before it destroyed all of Central City, Barry and Jesse entered Flashtime and attempted to figure out a manner to deactivate the nuke. Jay Garrick besides came from Earth-3 to try and help them. finally, the three speedsters thought it was a adept idea to cool down the atom-bomb and went to take Killer Frost into Flashtime. once in apparent motion with the speedsters, they brought her into the container where the microwave was located and attempted to send a shine of internal-combustion engine to cool it down, however, Frost began to burn up and her powers had no effect on the bomb calorimeter. In order to stop Frost from burning up, Barry puts her back into normal fourth dimension. She pleaded Barry to not let Caitlin die. Barry ends up taking Iris ‘ advice and stops the atomic warhead from destroying the city with avail from the Speed Force. [ 26 ]


team Flash came up with a design to attack DeVoe fountainhead on and enter his pocket dimension. Killer Frost, The Flash and Vibe then prepare to enter the pocket proportion and get the better of him. however, when they arrive, they realize that he wanted them there indeed that he could attack S.T.A.R. Labs with no issues. Harry, Joe and Iris were all attacked by DeVoe and his wife, Marlize. Iris was able to bring the three back and they attempted to fight DeVoe but he ended up killing Ralph and stealing his body. He then knocked Barry and Cisco back and when Frost attempted to stab him, he stole her powers and appeared to kill Killer Frost a well. He then knocked Caitlin back into a wall, unconscious. Caitlin undergo tests from Cisco and Harry, who were both unable to find any hound of dark matter in her body. [ 27 ] After Team Flash defeated Siren-X, the Earth-X doppelgänger of Laurel Lance, Caitlin found out that Killer Frost is still alive but without any benighted matter in Caitlin ‘s body, she is ineffective to appear. [ 28 ] The team began to help Caitlin to try and get Killer Frost to reemerge, they ran tests that involved Cisco shooting her with his vibration blasts, which caused nothing to happen. however, while Barry and Cisco are fighting DeVoe, Caitlin appeared and used Leonard Snart ‘s accelerator on DeVoe in an attempt to get Killer Frost to return, but to no avail, and becuse of Caitlin ‘s intervention DeVoe about killed Gypsy. [ 29 ] Caitlin never apologized to Gypsy or Cisco for about getting Gypsy killed by DeVoe. even desperate to get Killer Frost back, Caitlin last went to Amunet for help oneself. She led the team to believe that they needed Amunet to help defeat DeVoe and they all managed to get her to help them. Caitlin then struck a deal with her and told her that if she could get Killer Frost back she would do one prefer for her. however, it ‘s revealed that Amunet did n’t know how to bring her back but still gave Team Flash an item that could help defeat DeVoe. [ 30 ] When Caitlin went to therapy with Dr. Finkel, she revealed that Caitlin had been repressing a memory from her childhood, a memory which was very traumatic for her. She late asked Cisco to vibe her to this memory and see what happened merely to see her younger self induce hit by a car and then transform into Killer Frost. This revealed that Frost had been inside Caitlin even in her early childhood, before the atom accelerator explosion. [ 6 ] In the final battle against DeVoe, when Cecile went into parturiency, her powers which she received from her pregnancy kicked in and Killer Frost concisely inhabited her body. She grabbed Caitlin ‘s arm and told her that she had found Thomas and he had been that way all the prison term. [ 31 ]

team Flash had discovered that Caitlin ‘s founder ‘s death security was a fudge and that he was actually active. Barry, Caitlin and Cisco finally tracked him down to a warehouse owned by Tannhauser Industries .
however, it was late discovered that he was besides a cryogenic meta-human that had an evil split personality that attacked the team. The personality wanted to use a serum, that Caitlin reluctantly created, to kill off Thomas for good and inhabit the consistency himself. fair as he was about to inject himself, Caitlin managed to break through the mental block that DeVoe had created, allowing Killer Frost to emerge and shoot him back with an ice rink blast. He quickly attempted to convince Frost to take the serum deoxyadenosine monophosphate well and work with him but she refused, stating that Team Flash was her true family. As she walked towards him, she stood on and destroyed the serum. She created an ice-fist and began to punch him but stopped as Thomas ‘ personality emerged and spoke to Caitlin. This turned out to be a short reunion as the evil personality reemerged and shot her with an internal-combustion engine blast, proceeding to use two ice blasts to launch himself into the breeze and escape. Later, Caitlin discovered that she could use the cerebral inhibitor to speak to Frost through the mental block and the two began to catch each early improving. [ 2 ]

Meeting Cicada

During Thanksgiving, Caitlin, Cisco and Sherloque Wells decided not to attend the party at Barry and Iris ‘ apartment, causing Killer Frost to emerge. She questioned they ‘re decision of eating by themselves rather with friends who care about them and proceeded to walk off to the party, asking if they were coming or not. [ 32 ] During a struggle with Cicada, the stallion team was taken down by him and just as he was prepared to stab Barry with his dagger, Killer Frost emerged and fired an internal-combustion engine beam at him, sending him flying into a nearby van. He quickly stood and escaped the scene. The team late realised that Frost is immune to Cicada ‘s dagger and could be useful in defeating him. [ 3 ]


Killer Frost and Elongated Man were sent to Ivo Laboratories to help deal with A.M.A.Z.O., who had been unintentionally activated by an inexperienced Oliver Queen using Barry ‘s speedster abilities. The two and Officer Jones were unfortunately not strong enough and as they were floored by the android, it absorbed the two meta-humans ‘ abilities, using Frost ‘s abilities to fly through the roof and escape. [ 33 ] After traveling to Gotham City, Kara Danvers used Caitlin to gain access to Arkham Asylum, convincing the nurse that she was a mentally ill meta-human, evening cursorily flashing Frost ‘s eyes. After they got inside, a carouse began and the two split up. finally, Caitlin came across a delirious Nora Fries who was searching for something amongst the shelves. When Caitlin attempted to help her, Nora blasted a beam of cryogenic fastball at her, causing Killer Frost to emerge and engage in a fight. When Nora grabbed her conserve ‘s cryo-weapon, Frost asked for some aid over her comms but before Barry or Oliver could arrive, Nora blasted her back through a table, knocking her unconscious. [ 34 ]

Sabotaging the remedy

Whilst Caitlin was stitching up Cisco ‘s hand wounds, Killer Frost concisely emerged in order to freeze the wounds. Later, after Cisco began working on the meta-human cure, Frost appeared behind him and destroyed his workplace with a freeze blast. When asked what she was doing, Frost just stated that a meta-human remedy was not needed and that her and Caitlin were doing ticket together. however, Cisco explained that he wanted to cure all those who did not ask for their powers, including himself, who wanted to grow erstwhile with person and have a normal family. When Weather Witch and Silver Ghost were partaking in a dangerous joyride in Central City, Nora recruited Killer Frost for serve.

[ 13 ] former, Frost kidnapped Joe West ‘s girlfriend, Cecile Horton, outside of Joe ‘s home and threatened to kill her if Joe and the team did not hand over tracy to her and Savitar, belated at the conjectural exchange site, she claimed that killing Cecile would bring her no gladden but Tracy ‘s death at her hands would, when Barry tried to talk her out of it, she knew precisely what Barry was going to say, she and Cisco later faced off, and while she seemed sedate at beginning, she late fought back adenine hard as she can and lost to him, Cisco managed to get a sample of her blood, which could be the key to making a bring around for her. Before Cisco can take her, Savitar arrived and took her aside. [ 13 ] Despite all this, while reluctantly working alongside her early allies, it was proven that she distillery has a solid fastening to her memories of working at S.T.A.R. lab when she and Cisco reminisced about Ronnie losing his chasten back when they were trying to build the particle accelerator, however, Frost besides proved in this moment that thinking about who she used to be made her uncomfortable as she cursorily, dourly, stated that she did n’t want to stay any longer than she had to. Her conflict feelings about herself and her old allies were again emphasized when she told Team Flash she never loved them and left, lone for the assertion to hurt her center enough to cause the real Caitlin to emerge for a few seconds once she was out of the team ‘s sight. Despite Caitlin ‘s cover commitment to Savitar, she began displaying signs of regret and doubt in her treachery, during the final confrontation of Team Flash and Savitar, Cisco ‘s ageless loyalty for Caitlin finally enabled Caitlin ‘s true-self to become permanently restore and accommodate with her friends. At the lapp clock time, she felt lost, uncertain of who she is now. Six months after Savitar ‘s get the better of, Frost became stronger and finally was able to regain control on assorted occasions, recently Frost ‘s personality has become alike to Caitlin ‘s, after Iris convinced Frost and Caitlin that they could co-exist they decided to be allies and not enemies, Frost has besides become close with Team Flash, growing to appreciate their willingness to never give up on her despite her mistakes. She even assured Ralph Dibny that his friends will always be there for him when the latter briefly lost his confidence after failing a mission. As of 2019, Frost has mellowed out. After being let out by Caitlin to develop her own tastes and hobbies, Frost was helped by Ralph to learn how to improve herself and learn to consider the feelings of others. She gained a fondness for homemade art after learning it represented the heart of its creator ; something she sympathized with due to be her past of being repressed in Caitlin ‘s mind .
Post-Mirror Monarch, Frost was elated to discover her healing split her from Caitlin; allowing both them their individuality.

In an erase future where Savitar succeeded in murdering Iris West, by the prison term of the year 2024, Caitlin has become besides far gone to the point ; where she refuses to be called real name, as she prefers being called by her alias “ Killer Frost ”, she becomes angry when individuals call her by her very name .
Despite Caitlin’s insanity and cold nature, she is very observant, as she was able to realize that the Despite Caitlin ‘s insanity and cold nature, she is very law-abiding, as she was able to realize that the Barry Allen that she was speaking to was the younger-self of her Barry ; due to the look on his face, as the latter had not even become emotionally break, as his Iris was not abruptly however. This future was later erased when Savitar killed H.R. alternatively of Iris ; albeit by accident .

Powers and abilities


Persistent sub-thermal homeostasis with, uh, involuntary gelid substantiation. She gets cold and freezes stuff.
—Kara Danvers regarding Frost’s powers[src]
  • Meta-human/Cryogenic physiology: After Caitlin Snow’s father, Thomas Snow, discovered that she had the genetic marker for ALS, he used experimental cryogenic gene therapy on her to prevent the ALS from manifesting. The alterations Thomas had made to the treatment resulted in Caitlin developing a dual-personality (i.e. Killer Frost) and meta-human abilities soon after he treated her.[2] Caitlin’s Killer Frost persona, and the powers associated with her, remained dormant for 17 years (apart from a few brief episodes during her childhood), as several tests never showed signs of a meta-gene. Three years after the S.T.A.R. Labs particle accelerator explosion, Caitlin’s powers finally emerged fully.
    • Thermokinetic cryokinesis: By absorbing thermal energy from molecules to create gelid surroundings, Frost can generate dangerously low temperatures from her body, letting her freeze virtually anything.[7] She can thus create sheets of ice, or shoot spearlike icicles at opponents. Frost can also create an ice slide and use her cryogenic powers to rapidly propel herself forward on the slide.[13] Furthermore, her powers can reach such low levels that they can completely negate a speedster’s healing powers and alternatively neutralize accelerated decomposing; by generating temperatures as low as -360 degrees, she proved able to shatter beings as powerful as the Black Flash.[15] Frost often gestures when using her powers, but she can also freeze things by touching them (e.g. Frost can freeze people through a kiss)[8] or being in the same vicinity.[47] She was also able to freeze the light-based bullet from photon rifle in order to remove it from her body.
      • Cryokinetic breath: Frost is able to exhale cold mists with enough momentum to knock several people backwards and off their feet.[18] She could also use this as a means to produce a thick and obscuring fog.[8]
      • Cryokinetic blasts: Frost is able to produce blasts of Ice and was able to attack many opponents with this ability and we seen this ability use throughout the series, especially when she fought Chillbliane and when she was fought off the guys in the bar who wanted to collect the bounty for her capture.
      • Cryokinetic constructs: Using her thermokinetic cryokinesis, Frost can create constructs made of ice and icicles as shown in multiple occasions. During the Earth-X invasion, Frost was able to create ice swords to fight the Nazis and we also see Frost uses ice daggers as her main weapon to might opponents such as her fight with Cicada and her fight with Grace Gibbons, Frost was wielding two daggers and was able to go toe to toe with Grace but was overpowered. She can also turn her dagger into a sword and back in order to pierce her opponent through her own body.
      • Cryokinetic healing: Frost is able to heal injuries by filling the wounds with ice. As the wound heals, the ice will thaw until its fully healed, the ice will be melted by the time its healed. For example, when she used this ability to help with Cisco’s hand after Cicada’s dagger cutted him, closed up Cicada’s chest wound after removing the dark matter shard, and when Joe was injured by Ramsey’s zombies.
      • Limited atmokinesis: Frost’s powers can also somewhat affect the weather around her, dropping the climate of the area and causing it to snow.
      • Flight: By generating cryogenic thrust, Frost was able to propel herself to the wall and then, to the ground to avoid herself from falling. Another instance is when we seen Frost propel herself into the air to fight her father’s alter-ego, Icicle, by creating ice slides and she used this ability before when she took on The Flash while trying to kill Tracy Brand.
    • Eye transformation: Frost is able to change her eye color whenever she uses her powers and her eye color transform to blue color. We seen this occur in multiple occasions; specifically when Frost started to emerge when she was with Catilin and when her emotions where heightened as Caitlin stated to Mick that whenever she is scared or annoyed, Frost appears and afterwards, Mick tried scaring Caitlin, causing Frost to emerge.
    • Cold immunity: An added benefit to her powers, Frost’s cells can withstand subzero temperatures, seeing as her body temperature was unaffected when Icicle decreased the temperature in a lab to absolute zero.[2]
    • Accelerated healing: While accessing her powers, Frost’s metabolic rate is augmented to offset cold tissue destruction, allowing her to regenerate from damage sustained on her body at a rate much faster than even a speedster; however, foreign matter must first be taken out to not impede the healing. After clinically dying from a combination of a seizure and her reopened impalement wound, she was immediately resuscitated into a stable and cognitive state while her wound seamlessly healed completely in seconds. Her healing is strong enough to withstand a photon blaster that was able to disintegrate a person in seconds. She was also able to quickly heal her self-induced wound when she stabbed herself with ice dagger.
    • Superhuman durability: Frost has shown remarkable durability, seeing as she has tolerated substantial amounts of physical distress; for example, she has survived being hurled into a car and electrical box by Vibe’s concussive blasts without sustaining any serious injury. On one occasion, Frost stabbed herself through her stomach with her ice dagger in order to also stab Chillblaine, who had her in a headlock, with only minimal flinching.

former powers

  • Possession: After Frost was removed from Caitlin by Clifford DeVoe, she briefly gained the ability to inhabit another body. She used this to briefly inhabit Cecile Horton’s body. After she was restored to Caitlin, Frost seemingly lost this ability.
  • Mental communication: Frost and Caitlin were able to talk to each other whenever one of them was in control. After having a separate body, both Caitlin and Frost lost this power and now have to speak to each other through conventional means.
  • Velocity X enhancement: After injecting herself with Velocity X, Frost gained the powers of a speedster.
    • Electrokinesis: Like all speedsters, Frost could generate electricity from her body, which was blue in color. Due to having mastered her ice powers, (and possibly also from experiencing Flashtime before), she adapted to her newfound speed immediately. She was able to generate her remaining Velocity lightning on command, and unleashed a powerful lightning-enhanced cryo blast.
    • Superhuman speed: While her speed was not measured, she was able to keep up with and even outpace the Flash, who is able to run well over Mach 13, and was freshly recharged from the artificial Speed Force. Though she outpaced Flash due to having a similar familiarity with Central City and using her ice powers to slow him down, Flash was presumably running at his top speeds against her, noticeably exerting a lot of effort to phase and dodge her ice blasts.
    • Superhuman agility: Frost was incredibly agile, able to change direction immediately. She was able to make sharp turns on city streets while moving at super speed without sliding or losing her balance, and simultaneously use her ice powers, even on vertical surfaces, to create ice walls and ice blasts without slowing down.
    • Enhanced durability: Frost was able to get up with little to no injuries after being sent flying through the air and crashing into a car from an extremely high height. This was due to her already superhuman durability and her body adapting to the Velocity speed boost.
    • Superhuman reflexes: Frost’s increased speed also augmented her reaction time, allowing her to react to danger and events far faster than a normal human.
    • Superhuman stamina: Frost’s body could handle the stresses of superhuman racing without noticeable distress, and her body’s enhanced stamina allowed her to function much longer than a normal human without becoming tired or weak.
  • Cold fusion enhancement: After Frost’s powers got enhanced by the Mental Augmentation Chamber, she became more powerful than ever being capable of matching Deathstorm’s abilities. Her cryokinetic abilities were restored by Caitlin briefly before dying, thus losing her new powers.
    • Flight: Frost was able to fly at high speeds after her transformation.
    • Pyrokinesis: Frost could manipulate and control fire created by extremely cold temperatures.


  • High-level intellect: While not quite as intelligent as her sister Caitlin, Frost is exceptionally intelligent. She is also very creative and adaptive especially in the field.
  • Expert hand-to-hand combatant: To an unknown degree, during the six months in which she worked as an enforcer for Amunet Black, Frost developed a measure of sheer hand-to-hand combat skills. She once reversed an arm bar Norvock exerted upon her, slamming and pinning him painfully against a pinball machine. Frost also managed to hold her own against and even briefly injure Orlin Dwyer. Frost was able to fight on par against an older Grace Gibbons for a while, but was eventually overpowered. She was able to fight a zombified patient at a hospital with ice brass knuckles and later fight a group of zombies with Joe. By 2021, Frost’s fighting skills had improved significantly, likely from having received training from Barry as well as being out in the field more. She was able to swiftly defeat a bar full of criminals alongside Mark Blaine, and hold her own against Mark himself in their first encounter. In their second encounter she was able to overpower and defeat him.
    • Skilled swordswoman: During the Earth-X invasion, Frost was able to create ice swords and take down multiple Nazis with ease.[19]
    • Expert knife-wielder: Frost uses ice daggers as her main weapon and has used them on multiple occasions in fights with her enemies. During a fight with Cicada, Frost used a dagger as a weapon; managing to injure him.[36] On two separate occasions, Frost fought on par with Grace Gibbons, Frost wielding two daggers, for a while, but she was eventually overpowered.[41][43]
  • Artistic: As was first seen shortly before the Anti-Monitor Crisis, Frost struggles to expressing her emotions and imagination and it was evident when she attended Kamilla’s art gallery and was unable to see the purpose of those paintings and referred to them as “garbage” and afterwards, she started to secretly express her imagination by starting to draw a photo of a ice queen having to be caught by Cisco and confessed that she is trying to express herself and afterwards, she started to express herself with art and started to paint and draw as shown when she was painting in Caitlin”s apartment.[73]
  • Peak of human physical condition: Frost is in top physical condition as shown as she is working out and staying active by catching bad guys and fighting meta-humans with Team Flash and also, we seen her working out in “Growing Pains”, we see Allegra, her close friend, helping her workout as she is in S.T.A.R labs to avoid getting capture from Kristen Kramer.
  • High tolerance of pain: During the six months in which she worked as an enforcer for Amunet Black and with the help with her healing ability, Frost probably learn how to tolerate pain as she was able to learn how to fight and her ability allow to heal quickly after she is injured, it make get use to pain and to survive more painful attacks by overpowered opponents. Also, we see Frost tolerable to pain as Caitlin kept pushing off her impulses when she started to emerge and we see her continuing to push her impulses until she was able to be surface.

Alternate reality abilities

  • Peak of human physical condition: As a henchwoman of Superman, Frost was in top physical condition.[50]
  • Expert hand-to-hand combatant/Martial artist: Frost was a highly skilled hand-to-hand combatant and martial artist; she was able to overpower Oliver Queen with help from John Diggle when Oliver had lost his abilities.[50]


  • Carbine: Frost has implied that, like to her Earth-2 counterpart, her powers have no effect on carbine.[12]
  • Power-dampening tech: Like most meta-humans, if Frost is wearing power-dampening cuffs; she can’t use her powers. She can also be contained in a power-dampening cell.
  • Doctor Light’s photon rifle: When she was shot with Doctor Light’s photon rifle, which was lethal to everything it touched, it created a wound that troubled Frost’s accelerated healing, and after battling Sunshine the wound opened back up and worsened its effects.
  • Abnormally high temperatures: Intense heat can apparently negate Frost’s powers. However, the super speed she gained from Velocity X didn’t negate her powers, since her thermogenic cryokinesis negated the heat that she generated.
    • Flashtime: Frost can’t properly access her powers in this state, since this causes friction between her atoms, which creates extreme heat under these circumstances. Put simply, she is not able to access her powers because Flashtime is an external source of speed, rather than an internal one that can be counterbalanced. [26]
    • Nucleokinesis: It is likely that similar to her late Earth-2 counterpart, Frost will be severely affected by nuclear energy.


original multiverse

  • Frost suit: Whilst fighting crime, Frost dons a protective suit for aid in her battles. The first suit was mainly for her evil persona and she eventually stopped wearing it after joining Team Flash, where she then wore a baby blue jacket with leather bottoms. After returning from her disappearance, Frost never gained an official suit at first, mainly just wearing black, until Cisco created a new, dark blue suit, similar to her first suit.
