**Caitlin "Cait" Snow** is a female Meta-human who is a former criminal, former lieutenant in The League of Assassins and former henchwoman to Amunet Black. She is the daughter of Carla Tannhauser and wife of the late Ronnie Raymond. She was given metahuman abilties by being hit with dark matter from the S.T.A.R Labs particle accelerator. She used her powers rob stores and obtain money and began calling herself "**Killer Frost**". She was assigned with the task of killing Green Arrow and his friends by Amunet. After failing to kill the heroes Caitlin was taken into The Arrowcave as Oliver could tell she wasn't as cold hearted as she lead people to believe. After a huge pep talk, Caitlin didn't reform her criminal ways but instead tried to be more cold hearted and decided to try and kill Amunet. However when she attempted to assassinate her former boss but was overpowered until her supposedly deceased husband, Ronnie, showed up and burned Amunet to a crisp. After this incident, Ronnie and Caitlin began going by "Deathstorm" and "Killer Frost", wreaked havoc among Starling City and fought Team Arrow many times until Deathstorm was killed by Ra's al Ghul because he wouldn't follow orders, however, Caitlin still did what he said.

Caitlin was even more heartbroken and cold after this but still continued her life of crime around Starling City, only this time more skilled and ruthless. Her only plan was to get money, get a new identity and start a new life. Eventually all of this failed and she was imprisoned in Iron Heights.

Caitlin was supported in court by Laurel Lance, who felt very sorry for her. Eventually, she was miraculously cleared of all charges thanks to an "anonymous source". After being released from jail, she was convinced that the old Ronnie would have wanted her to use her powers for good, so Caitlin became a vigilante and joined Team Arrow.

However, Caitlin's powers began to grow stronger and through unknown reasons, she began to slowly return to her criminal life and began to work for Felicity Smoak/Overwatch. When Felicity was defeated Caitlin was injected with a cure that would allow her to control her powers without being evil.

## Biography

### Early Life

From a young age, Caitlin idolized her parents who were both doctors and was inspired to follow in their footsteps. Growing up Caitlin practiced the Hippocratic oath and was obsessed with it. She grew to value life so much she wouldn't even let anyone step on a bug if she could help it. From a young age Caitlin was very close with her father. One Christmas they sat and watched old movies together as it snowed for hours without end outside. However Caitlin's father suffered from multiple sclerosis. Her mother, Carla Tannhauser tried to save him as he fought it for years but he eventually died, much to Caitlin's heartache. Following her father's death Carla began focusing only on her work as a way to cope with losing her husband, but her neglect of Caitlin left them estranged for several years.

In high school, Caitlin was bullied by Lexi LaRoche who put chewed bubble gum in her hair. In adult years Caitlin had no support system and turned to drugs and alcohol for help. Some time before 2011 Caitlin was beginning to rob stores and buy drugs. Sometime after this she met Ronnie Raymond an officer who in contrast to Caitlin's guarded outlook was more outgoing. Caitlin would later describe them as being "Fire and Ice". Despite being very different the two fell deeply in love and started dating, Ronnie did not know that she was a criminal but he did stop her from taking drugs and drinking oversly.

Around 2012, Caitlin went out of town with Ronnie for their one year anniversary. Eventually Ronnie proposed to Caitlin and she accepted. However she apparently never told her mother as she wouldn't even be aware Ronnie existed until over 1 year after his actual death.

### Particle Accelerator Explosion

Caitlin was outside S.T.A.R Labs at the time the accelerator was to be switched on. She and Ronnie were discussing their honeymoon when they heard a huge explosion. They both looked up to see a huge wave of dark matter coming towards them, they both started to run but one of the windows of S.T.A.R labs smashed and a wave of radioactive dark matter hit Ronnie and seemingly disintegrated him. Caitlin watched on in horror, tearing up, she tripped over her own foot and fell into a huge pile of snow when the dark matter hit her and gave her ice powers.

   After the accident, Caitlin tried to walk back to her apartment, cold and heartbroken. However on her way she ran into a man who tried to mug her but she instead launched an icicle right into his chest, killing him. This was her first kill as Killer Frost.

### Becoming a Criminal

After witnessing her fiancé's death and killing someone Caitlin was pushed over the edge and went on a killing spree in the streets of Starling City and also robbed stores to obtain money. Amunet Black saw how skilled Caitlin was at killing and how much havoc she could cause so Caitlin was recruited into Amunet's criminal gang along with Livewire.

### Facing Team Arrow

After one of Amunet's deals was sabotaged and ruined by The Green Arrow, she sent Livewire and Killer Frost to deal with it. When they got to the scene, Green Arrow had Spartan and The Canary to back him up, so the fight began. Livewire went straight in with electrical whips and huge bolts of lighting originating from her fingertips. Killer Frost shot out huge beams of ice and hit Canary square in the face. Canary decided to get up close and personal and began hitting Frost with her staff. Frost managed to dodge most of the hits but was still knocked backwards into a glass wall that shattered all around her. Frost got up and began to freeze Canary's torso until she couldn't move and went in for a close attack and jumped onto her and brought her to the floor shattering the ice and rendering Canary unconscious. She then went to assist Livewire with Green Arrow but found her unconscious on the floor in a puddle of water. Frost was then attacked by Green Arrow from behind and he attempted to knock her head on the wall but she did a full circle around him and knocked him down. Before he could get back up Frost froze his body and he wasn't able to move. Before she could finish him off, he said her real name, "Caitlin Snow", she was shocked to hear her name after so long and she stepped back with a scared look on her face before being hit on the head with Canary's Bo Staff.

Instead of being incarcerated at Iron Heights like Livewire, Caitlin was brought into The Arrowcave. She was very confused as to why she didn't go to prison and Green Arrow told her that he saw a tiny piece of goodness in her tonight. Caitlin refused to believe that any piece of her was still good. She completely refused to accept it, she agreed to herself that she would be even more cold and cruel. When Team Arrow discovered Amunet's location Green Arrow, Canary and Spartan all went out to take her in but the three were overwhelmed by her powers and couldn't defeat her. The only two people left in The Arrowcave were Caitlin and Cisco Ramon, they both knew the team's only hope was Killer Frost so Cisco annoyingly opened her cell and she knocked him across the room. After defeating Team Arrow, Amunet was gathering her things to get out of Starling City when Killer Frost broke through the skylight and tried to stick an icicle in her neck, but Amunet used her magnetic powers to hit Frost over the head with a toolbox, both of them scuffle before Amunet is standing over Caitlin with sharp metal objects floating over her chest. Before Amunet could kill Frost she is set on fire and falls on the floor, screaming in pain, before she goes quiet and the flames cover her completely.

When the smoke in the room clears, there stands Caitlin's deceased fiancé Ronnie Raymond, Frost thinks she's hallucinating for a moment and doesn't believe he's real, until he comes over and gives her a kiss. Caitlin is so happy, but confused, that he's back. The two reconcile and Ronnie explains that when he was vaporised, his body was only lifted up into the fire and he became pure energy, he also explains that he has been through a lot and that he has changed. Frost says she likes the differences. Just as they are about to kiss, Canary and Spartan run into the room and Canary screams at them both but Ronnie launches a fireball at them but before it can hit them, Spartan grabs Canary and rolls out of the way. Ronnie then grabs Caitlin and they both fly off.

### Killer Frost and Deathstorm

To Caitlin's surprise, Ronnie had turned to a life of crime and began calling himself, Deathstorm. They both took over Starling City's criminal underworld and became the so-called "king and queen". They both helped Ra's al Ghul in his quest to kill the Green Arrow who they learned is actually Oliver Queen. Killer Frost and Deathstorm also got married during this time.

Caitlin was sitting in her newly founded office when her husband storms in claiming that Ra's is idiotic and he needs to die. Killer Frost tells him that once his plan plays out nicely they will both end his life, together.

In order to torture her mother as revenge for a terrible childhood, Caitlin went to her apartment in Central City and kidnapped her. Caitlin brought Carla to an abandoned warehouse back in Starling City but didn't use physical torture, but psychological torture by showing her pictures and videos of her late father and then showing a photo of his smashed, icy grave. This drove Carla insane and she even tried to take her own life at one point but Caitlin stopped her and made her indure more pain.

Eventually, her mother escaped and told Team Arrow everything, much to Caitlin's annoyance. A few days later, when Tannhauser went back to work at her company, Tannhauser Industries, Killer Frost attacked her again and almost killed her until Team Arrow showed up. While Tannhauser leaves Killer Frost begins shooting Icicles at Black Canary and then shoots a stream of ice at Spartan and begins to make a run for it just before Green Arrow jumps in and hits her in the face, knocking her backwards. Frost doesn't stay down however, she gets up and starts to run at arrow, shooting icicles at him at the same time. Green Arrow dodges all of the icicles and shoots an explosive arrow at her but she cartwheels out of the way and freezes the ground below him, making him fall over and smack his head on the ground, dazing him and giving Frost a chance to escape, which she did.

When Ra's decided to initiate the final part of his plan, he called Killer Frost and Deathstorm to his lair and knew Team Arrow was going to show up eventually. When they appeared Ra's ordered Killer Frost and Deathstorm to attack them, which they proceeded to do. They enter and Frost freezes the ground, causing Team Arrow to fall, Deathstorm conjures two fireballs and orders them to stay down. The Team try to convince the two criminals that Ra's will kill them both when he's done with them, but this speech just causes them both to laugh and Deathstorm confesses that they are planning to kill him after his plan plays out. Killer Frost tells him to shut up incase Ra's is already here, but it is too late and Ra's stabs Killer Frost in the arm with his sword and proceeds to stab Deathstorm through the heart, killing him instantly. Frost screams but before she could do anything Ra's picks her up by the throat and tells her that he still needs her, so she won't die, yet. He drops Frost and then throws down a smoke grenade and disappears, when it clears, Killer Frost is also gone.

### Continuing to work for Ra's

After her husband's death, Killer Frost still worked for Ra's out of fear for her life, but knew he was going to kill her after he was finished with her.

When Oliver Queen, Laurel Lance and Cisco Ramon tried to find Ra's al Ghul's lair, Killer Frost appeared out of the shadows and told them to back up and go the other way before she's forced to kill them both. All three of them could tell that Frost was sleep deprived and looked very nervous and scared. Oliver tried to reason with her but she didn't listen at all and started firing icicles at them, however, they dodged them all. The three split up and hid behind the trees trying to stay out of Killer Frost's line of sight, she came across Laurel who attempted who to scream but Frost was too fast and grabbed her by the throat and held her against a tree. Frost was about to finish Laurel off when Cisco held a gun to her face, threatening her. The team take Frost aside and try to talk her out of working with Ra's al Ghul, she explained that she hates him with a burning passion and wants to kill him, but when she's with him he watches her every move and she couldn't get a chance to take him off guard. Cisco asked her to help them get rid of him once and for all, she agreed, but did not look happy about having to team up with her enemies. When they approached a huge cliff Oliver, Cisco and Laurel didn't know what to do until Frost steps up and explains she can make a path of ice to get up to the lair and kill Ra's. They all agree and climb up to face him.

    When the four reach the top, Ra's is waiting for them and tell them he's been watching them the whole time and is going to kill all for of them, but before he kills Killer Frost, he needs her meta human abilities to power his ice relic. Oliver tackles Ra's and Laurel begins screaming at him but he knocks them both out of the way and stabs Laurel in the stomach in the process. Cisco tries to hit him with his powers but misses and gets hit across the face with the handle of his sword. Just when Ra's is about to finish the three off Killer Frost shoots an icicle through his head and kills him instantly. Frost feels so much better now that she's avenged her husband and that she's free, Oliver gets up to thank her but she covers the room in an icy mist and when it clears, she is gone.

### Attempting to Start a New Life

Killer Frost began to rob banks and get away as fast as she possibly could with Team Arrow always arriving too late. Except once when Frost couldn't get past the FBI, shortly after this she was brought to Iron Heights Penitentiary.

### Life in Iron Heights

    While Frost was in Iron Heights she was always kept in her meta human cell and wasn't allowed out in the yard. She was frequently visited by Laurel Lance who actually felt bad for her and wanted to get her out. Frost hated prison and gladly let Laurel get her out. Laurel was called into the courtroom with Killer Frost, who accepted to be called by her real name, Caitlin Snow. Laurel convinced the judge that Caitlin was forced to work for Ra's al Ghul and was threatened to be killed, Laurel also explained that she was put into a very dark place as the love of her life had been murdered in front of her. The judge said that he understands where Laurel is coming from but still thinks Caitlin should spend time in prison for her crimes. Caitlin agrees with him and her sentence is lowered from 10 years to 1 year.

### Getting out of Prison and Becoming a Vigilante

A year passed and Caitlin got out and went to Queen Manor to thank Oliver for all him and his team did for her. Oliver greets her and they both go around to the gardens, and she thanks him for helping her see the light side of life and for getting her out of a terrible situation. Oliver hugs her and tells her it was no problem, she is about to leave but he tells her to stay and asks her if she wants to use her powers for good. Caitlin doesn't exactly know how to answer his question but she does know that the old Ronnie would want her to use her powers to save people. Caitlin accepted Oliver's offer and she was officially a member of Team Arrow.

### Team Arrow

When Caitlin joined the team, she got a new upgraded suit that was described by Cisco as being a lot less evil. She did also keep her name "Killer Frost" but she wouldn't kill anybody, this was only to scare criminals. She also really changed her civilian style to a more modest style of clothes.

In Caitlin's first few months fighting crime, she did feel like she was making up for the trouble she had caused prior. However, she questioned her alignment and considered stopping to use her powers incase she was persuaded to become evil again. When the team had a meeting to welcome the new recruits Oliver noticed that Laurel was acting very different and asked Caitlin about it, Caitlin told him that she thought Laurel was acting very differently as well. Oliver told her to keep an eye on her. On her way back to her apartment, Caitlin was ambushed and thrown into a back alley by an unseen attacker. She turned into Killer Frost and was ready to fight whoever it was but was shocked to see it was Felicity Smoak. Felicity asked Caitlin to join her team and aid in her revenge against Oliver Queen. Caitlin refused and attempted to walk away but was stopped by Felicity. She told Caitlin that she has seen all of the panic she could cause and that she ran this city once and she can again. Caitlin's eyes glowed white and she conjured an icicle in her hand while putting Felicity into a choke hold, holding the icicle to Felicity's chest, Caitlin threatened her to not contact her again or the next icicle will go straight through her heart. With fear in her eyes, Felicity fled the scene leaving behind a frightened Caitlin who knew she had to get rid of her powers at all costs.

### Returning to Evil

Desperate to understand what was happening to her, Caitlin visited her mother but was quickly annoyed when she asked if Caitlin had received her birthday card which she confirmed, in April, presumably a significant amount of time before or after it. Caitlin inquired how to get an appointment with her for a friend, not ready to reveal her secret, but as Carla coldly walked her through the procedures Caitlin angrily froze her desk and revealed she was the patient. Carla subsequently canceled all her appointments for the day and readied various tests for Caitlin. While preparing she met Carla's assistant Nigel. Caitlin was brought down to the facility's testing lab for molecular motion where she revealed a shaft made of solid tungsten, heated to over 2000 degrees centigrade. Carla asked Caitlin to freeze it in order to determine how to reverse what's happening to her. To her horror she froze it solid within seconds. After Caitlin revealed the origin of her powers, she and Carla fought over Caitlin working at S.T.A.R. Labs rather than Tannhauser Industries, which Caitlin reminded her was because she desired to make a name for herself. Before they could argue further Nigel came back with the results and revealed that Caitlin had not just frozen the tungsten but had absorbed all the energy it was emitting. However Caitlin was frustrated when she heard them talking about how her power could benefit their pursuits rather than offer sympathies. When Carla began taking blood samples Caitlin, finally having had enough, confronted her over he seemingly lack of care for her well-being and how she hasn't expressed any concern over her well being since her father died. Carla defended that she tried to save him and reminded Caitlin that she ran away but Caitlin told Carla that she had to because she wouldn't even so much as look at her. Carla accepted Caitlin's anguish and admitted that she got consumed in her work out of grief but scolded Caitlin, believing she didn't know what that kind of loss feels like. Outraged, Caitlin told Carla about Ronnie, who Carla didn't even seem to be aware of.

Having had enough, Caitlin decided to leave but Nigel trapped her in the facility wanting to exploit her powers for himself. As he grabbed her Caitlin's inner Killer Frost persona was released in a fit of pure rage and she grabbed Nigel and froze his arm solid. Carla came into confront her, and Killer Frost ordered her mother to move, but Carla offered her apologizes, acknowledging that she wasn't much of a mother, but was steadfast that she didn't raise a killer, managing to talk her out of killing Nigel as mother and daughter hugged.

Later Carla contacted Caitlin via webcam and told her that her results proved unfruitful; that Caitlin's biology was rapidly changing and the more she used her powers the less control she'd have. After hearing this, Killer Frost's anger emerged again, as Caitlin has accidentally frozen her computer, horrified to see that she was losing control over her emotions along with her growing meta-human powers. After Cisco accidentally vibed Caitlin in the guise of evil Killer Frost, he forced her to reveal the truth about her powers to the team.

Caitlin said she wouldn't save Oliver from Silver Banshee, for fear of using her powers and unleashing her evil side, and only went after Laurel begged her. And after using her powers to save Oliver from Silver Banshee; unfortunately, she ended up dominated by her worry and anger, turning into Killer Frost. She went after Felicity Smoak in an attempt to rid herself of her powers through some kind of tech. She tricked Quentin into believing that Sara had returned and was well, trying to divert Quentin from the interrogation of one of Silver Banshee. She tortured Banshee, but before she could extract any useful information, Caitlin was forced to flee by approaching SCPD officers, leaving Silver Banshee frozen. Still obsessed with finding Overwatch, Killer Frost kidnapped Cisco, forcing him to create a search algorithm to find Felicity's teammates. Cisco succeeded in locating Black Siren, but also alerted the police to Killer Frost's location, as she tried to kill him, however, Green Arrow arrived and attempted to talk Caitlin down. Unfortunately, Caitlin was unable to control her powers; too far gone and panicked, she stabbed him in the leg and went after Black Siren. Upon arriving, she threatened to put an icicle in Siren's chest, forcing her to comply. She informed Killer Frost that she didn't know where Felicity was, however, before she could press for more info on how to take away her powers, Vibe arrived and, like Oliver, attempted to talk her down, but Killer Frost attacked Cisco. Oliver then arrived on the scene and shot a trick Arrow that tied up Killer Frost. Unwilling to surrender, Killer Frost froze out of the rope and gave Oliver a kiss, using her powers to freeze him solid. Luckily, Cisco was fast enough to smite her with a Vibe burst, knocking Killer Frost unconscious. Upon waking up in the Pipeline, Killer Frost attempted to convince Team Arrow she was back to normal, to no avail. She then made an offer of leaving them alone, if they release her and allow her to go on her way. But Oliver refused to abandon her, angering Frost. Barry returned, asking for Caitlin's help with an injured Thea Queen, was shot and is bleeding out. Killer Frost taunted Oliver, who released her on one condition: if she wanted to leave, she had to kill him. Killer Frost threatened to do so, producing an icicle, but was unable to kill her friend. Crying, Caitlin finally snapped out of her anger and she hugged him, horrified at her actions.

Green Arrow and Speedy later captured another member of Felicity Smoak's team and Caitlin's former teammate, Livewire, and locked her in a metahuman cage in the Arrowcave. However somehow she fried the wiring in the cage and managed to completely black out the cave. She then went to collect a mysterious power source from the basement of The Arrowcave, and set off an explosive as the trio attempted to chase after him upon his escape. The resulting explosion impaled Caitlin's side with shrapnel. Team Arrow took her to the med bay and helped her onto the bed. Caitlin showed signs of physical pain, as she was breathing heavily and moaning. Cisco tried to stop the bleeding with a T-shirt while the team decided how they was going to help her. Diggle X-rayed her and found she had bits of metal wedged inside her that needed to come out. Caitlin refused to go to the hospital as they will find out about her Killer Frost identity. Laurel told the team that Caitlin couldn't operate on herself but Caitlin said she could if she had a mirror, she could talk someone through the surgery. Soon after Caitlin talked John through her own surgery. Laurel helped stop the bleeding as John operated. As John came to the last piece of metal he found that it was stuck, as he tried to get it out, Caitlin's heart rate began to increase dangerously, causing Cisco to worry. John told her it was going to hurt as he pulled the metal out, Caitlin screamed in severe pain before becoming light headed and telling John to stitch her up as she was going to pass out. Later that day, Cisco was alone with Caitlin. She seemed to be recovering well, but as they were talking, Caitlin stopped mid-sentence and passed out. She started seizing. Cisco panicked and called for help. John came running in with Thea. and they tried to hold her down, but she suddenly stopped. Cisco put his hand above Caitlin's mouth and found that she wasn't breathing. John began giving her compressions and told Cisco to get the oxygen mask and place it over her mouth. They then tried electric shock, but everything was unsuccessful. John tried more compressions while Cisco continued giving her oxygen but Caitlin wasn't responding and they couldn't resuscitate her. Cisco started crying, realizing his best friend had died. Thea and John began crying as well however, a moment later they heard a sound and saw her meta-human powers begin to regenerate her. About 30 seconds later, she began breathing again. Caitlin's wound also healed instantly, but she emanated a cloud of mist, sending the team and herself flying. Once the cloud cleared, Caitlin had transformed into Killer Frost and attacked the team before escaping.

### Joining Felicity's team

Caitlin wandered around in the snow, only to encounter Overwatch. She asked if Felicity wanted to cure her, to bring Caitlin Snow back, but she wanted just the opposite. Felicity held up her arm and a hologram appeared of a future Killer Frost, running the streets of Starling City and killing anyone who wronged her. Killer Frost loved this sight and wanted it to be her own future so she joined Felicity's team.

She was sent by Felicity to the Central City University in order to kill Dinah Lance, Laurel Lance's mother. However her attempt on the teacher's life was thwarted by the intervention of Oliver, Thea and Cisco with a disguised Laurel at their side. She returned to Felicity to tell her about the failure, with Felicity questioning Frost's loyalty, believing their was more Caitlin Snow in her than she was led to believe. She then told her that it is too late for Dinah Lance to die and that the final phase of the plan can begin.

She and her associate, Livewire, later helped capture most of Team Arrow, and brought them to the now trashed Queen Manor with Moira Queen as a hostage. Oliver, in turn brought the former league of assassins member, Nyssa al Ghul and the former criminal, Malcolm Merlyn. They found the cages with Oliver's son William Clayton and Team Arrow members, Thea Queen and Cisco Ramon. However, the trio were ambushed by Killer Frost and Silver Banshee But as Slade suddenly lashed out at Digger, Killer Frost fired an icicle at William, only to be intercepted by Oliver's dart. The two were then thrown back by Malcolm's explosive arrow, Nyssa then took out a sword and was ready to fight but Frost covered the area in an icy mist and escaped, leaving Banshee behind.

Later, Killer Frost realized that the hostages are escaping when she was intercepted by Vibe. Killer Frost taunted Cisco for not being able to talk to Caitlin again and how she's going to slowly kill him, Cisco told her that he will see Caitlin again and that Killer Frost is going to die. Frost then dueled with her former best friend and was defeated, and as Cisco held his hands up ready to kill her, she taunted him into killing her by stating she'll kill him if he she gets the chance, but as Cisco couldn't bring himself to do it, he knocked her unconscious. Felicity had rigged the manor with explosives with her heartbeat dropping as the trigger, and eventually jumped off a balcony in the manor, knocking herself unconscious, which in turn, destroyed the manor with Killer Frost still in it.

### Writing Her Wrongs

Killer Frost survived by hiding underground in a bomb shelter that was located under the basement. There she found Felicity's plans of the explosion and the cure for Killer Frost that she was going to give to Caitlin Snow.

## Personality

In her early years, Caitlin seemed very kind and caring. This was until her father's death, that also crushed her dreams of becoming a bio-engineer, she became very cold and guarded and never wanted to make friends.

After witnessing her fiancé's death and getting powers, she became very vicious and displayed no remorse for killing people. All of the events really pushed Caitlin over the edge and she wanted to kill everyone who had wronged her. When Ronnie returned and became Deathstorm Caitlin seemingly lost most of her coldness but still showed no remorse for her actions. After Ronnie and Ra's al Ghul's death when she got a year in prison, Caitlin seemed to open up a bit more and show a lot of regret for all of her actions of killing people. By the time she was out of prison she showed so much remorse that she decided to become a hero to right some of the wrongs she caused

As a hero, Caitlin went back to her young personality as a kind and caring person who always put her friends first. She also showed she cared for people she didn't even know when she saved a family from being crushed by falling debris from Laurel Lance/Black Siren's cry.

## Powers and Abilities

### Powers

**Meta-human physiology:** After Caitlin was struck by the energy of the Particle Accelerator explosion, this altered her DNA and supercharged her cells, augmenting her physiology to properly access her newfound powers.

* **Energy absorption/Cryokinesis:** Caitlin's powers work by absorbing all existing heat around her, thereby reducing the temperature and to freeze targets well-below negative 370 degrees. Caitlin can create various ice structures with ease, even creating large bullet proof shields that can with standing point blank automatic rifle rounds, as well as launching upon manifestation sharp projectiles in rapid succession, creating an icy blade around her arm or as means of transportation, by producing icy waves of such propulsive strength, with one hand behind her, to propel herself forth across an ice slide she forms before her with her other hand, similar to Firestorm's fire-based propulsion ability. Her powers can also affect the weather around her, dropping the climate of the area and cause it to snow. She can also freeze objects without direct contact shown when she froze H.R's coffee from afar. A tell-tale sign of her accessing her powers is producing icy mist from her hands.
* **Accelerated healing factor:** While accessing her powers, Caitlin's metabolic rate is augmented to offset cold tissue destruction, allowing her endure more grievous injuries and likewise heal much faster than even a speedster, though 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. However, her healing powers only work when her Killer Frost side takes over, as wounds inflicted by Amunet left bruising and required stitches. Interestingly enough, Caitlin's Earth Two doppleganger seemed to lack this aspect of their near-similar meta-human powers, which was what led to Earth Two Killer Frost's death at Zoom's hand.
* **Cold immunity:** An added benefit to her powers, Caitlin also exhibits a high resistance to frigid temperatures. She is shown to be able to hold the ice constructs she manifests with little trouble. She was also seen unaffected after she escaped The Arrowcave, when there was a snowstorm.
* **Freezing breath:** Caitlin is able to create a fog with her breath. Around six months following getting out of prison, Caitlin grew powerful enough to orally produce cold mists with enough momentum to knock back several people off their feet.

### Abilities

* **Computer specialist:** As a member of Team Arrow, Caitlin has ganed some technological skills of note, albeit not her main area of expertise as was evident in her ability to reprogram the S.T.A.R. Labs satellite to track sound abnormalities over Starling City, so they could find the location of Laurel Lance/Black Siren.
* **Expert medic:** Caitlin is an expert in medical care, as seen when she was able to cure Oliver Queen after he was poisoned by Malcolm Merlyn, and later, when she was able to patch-up the former when he was seriously injured by Slade Wilson/Deathstroke.
* **Genius-level intellect:** Caitlin is very intelligent, though not always shown. Her talents have been a crucial aid in helping Team Arrow. Also, she, along with Cisco Ramon, were able to create a more advanced cure for Mirakuru.
* **Expert driver:** Caitlin is capable of driving a car.
* **High pain tolerance:** Caitlin is shown to have a remarkable level of endurance. Despite the grievous injuries she gained from Vincent Sobel, she was able to maintain consciousness through the surgery to remove the shrapnel in her body, all while instructing Cisco.
* **Hand-to-hand combat:** Caitlin was a part of Amunet Black's criminal underworld, therefore, she was trained everyday by Amunet and gained enough skill to be come out successful in hand-to-hand combat
* **Marksmanship:** Caitlin was able to shoot a crazed Oliver Queen who was running around the Arrowcave trying to kill his team with Quentin Lance's gun.

### Weaknesses

* **Carbine:** Caitlin has implied that like her Earth Two counterpart, her powers have no effect on carbine.
* **Power-dampening tech:** If Caitlin is wearing power-dampening cuffs, she can't use her powers.

## Equipment

* **Killer Frost suit:** Caitlin wears a protective suit as her alter-ego, Killer Frost. She had the first version when she was a criminal that was given to her by Amunet Black. However, after she became a hero, Caitlin wore a different protective suit in battle. When she joined Felicity Smoak's team, she was given a new suit that seemed to be more tech based.
