"No, Mark Blaine, that was my name. But you can call me...Chillblaine."
—Mark Blaine[src]

Mark Blaine, self-styled as Chillblaine, is a resident of Central City and a former employee of Ivo Laboratories.


Early life

When Mark was 9 years old, he fell into freezing ice water during a skiing accident, resulting in him being submerged for fifteen minutes. After this experience, Blaine had grown up obsessed with cold and ice.

In his adulthood, Blaine decided to work for Ivo Labs in cryogenics. However, they fired him after he had conducted unethical experiments using their technology. After his termination, he saw the work of Killer Frost at hand and grew obsessed, leading to him began spying on her. Eventually, Blaine learned of her secret, that she was the alter-ego and split personality of Caitlin Snow, and sought to get her powers. He eventually designed a pair of gauntlets with nanotechnology, using them to replicate meta-human powers.[1]

Framing Frost

Sometime in mid-2020, Blaine began bartending at a bar in Keystone City where Frost formerly worked, later framing Frost for a murder he committed by replicating Frost's powers with his gauntlets. Blaine met Frost while bartending, revealing his true nature to her. The two fought people trying to capture Frost because they wanted the bounty placed on her by Kristen Kramer.

Later, after Frost figured out that Blaine had framed her, the two battled, with Blaine using his gauntlets to mimic Frost's cryokinesis; he was outmatched by Frost, who was far more experienced with her abilities. Blaine was then imprisoned in Iron Heights for his crimes.[1]

Breaking out of Iron Heights

Blaine was one of several Iron Heights inmates to break free after a storm that wrecked the prison. He began sporting a fur jacket when he was once again confronted by Frost, who had also broken out of Iron Heights to help find and apprehend the inmates. He left his jacket open and had no shirt in order to flirt with Frost. The two once again fought, with Blaine making several flirtatious remarks that caught Frost off-guard. However, Blaine was once again defeated and his remarks had left an impression on Frost, who began developing a crush on him.[2]

He was left out of prison in an agreement to become a state witness. Frost tried to apprehend him, but could not due to realizing it.[3]

Fighting the Godspeed clones

Due to becoming a state witness, he was wounded in the bar he worked as bartender. Frost made the group attacking him stop and persuaded Mark to accept going to S.T.A.R. Labs to be healed. Suddenly, an army of Godspeed clones attacked and Frost reluctantly gave Mark his cryogenic gauntlets. The two fought the clones, narrowly surviving the ordeal when the clones ran away to pursue The Flash. Later, Mark talked with Frost about the encounter and nearly kissed her. He then left after a drink shaker exploded.[4]


"...and you developed an obsession with refrigerators."

Mark is a charismatic criminal obsessed with cryogenic technology. While manipulative and arrogant in his abilities, he seems to have a genuine attraction to Frost, willing to fight alongside her.

Powers and abilities


  • Chillblaine gauntlets application: By using nanotechnology within Mark's gauntlets, he is able to replicate meta-human powers.
    • Power replication: Mark is able to use his gauntlets to access an almost perfect replica of Frost's powers.
      • Thermokinetic cryokinesis: By absorbing thermal energy from molecules to create gelid surroundings, Mark can generate dangerously low temperatures from his gauntlets, letting him freeze virtually anything. He can create cold mist beams. Mark can also, presumably, create an ice slide and use his cryogenic powers to rapidly propel himself forward on the slide. There do seem to be limits to this replication, however, as he does not create icicle spears, nor are his gauntlets able to control the weather.
        • Cryokinetic blasts: Mark is able to create powerful blasts of ice from his hands, powerful enough to propel a fully grown adult several meters away.


  • High-level intellect: Mark is an exceptionally intelligent individual, and by his own claim, the best cryogenicist.
    • Master Scientist/Engineer: Mark built a highly advanced microchip, and with access to a neurogenic scanner, was able to perfectly replicate Frost's ice powers.
      • Mixology: Mark is well-versed in making drinks, and can recite the scientific process and physics required to make said drinks.
    • Expert tactician/Manipulator: Mark was able to observe Caitlin Snow and Frost for years without being noticed, and had the resources to study every battle they had, as well as other areas of their personal lives. He was able to frame Frost and later tricked her into handing over her neurogenic information which allowed him to perfect his replication of her powers.
  • Expert hand-to-hand combatant/Martial artist: Mark was able to counter Frost's movements, gracefully catching or dodging Frost's attacks while both were not using their ice powers, and briefly gained the upper hand when using his chill gauntlets. His fighting style integrates Boxing, Taekwondo, Capoeira, and Jujitsu.
  • Peak of human physical condition: Mark is in excellent shape, sporting a well-muscled build.
    • Acrobatics: Mark is incredibly agile, dodging Frost's ice blasts with ease, gracefully performing complex backflips, rolls and flip kicks, while maintaining his balance. He also shared a short dance with Frost during their fight, albeit unintentionally.
  • Charisma: Mark is exceptionally handsome. Due to his well-muscled build and surprising intelligence as a bartender (and also later, graceful acrobatics) Frost develops an attraction to him, despite learning later on that he basically stalked her. This results in part of their first fight becoming a short dance, with awkward pauses between the two of them.


"To think, you have so much strength, so much power, but so little imagination. I guess that just means I’m a better meta than you."
"Actually, Chillblaine...You’re not a meta at all. One thing your bracelets can't copy, ice healing."
—Mark and Frost[src]
  • Limited power replication: While Mark was able to create a replica of Frost's powers, there seems to be a limit to how much he can copy, as he was unable to use ice healing to heal himself during his fight with Frost. He apparently also cannot create ice spears.


  • Chillblaine gauntlets: Mark uses a pair of high-tech gauntlets that generate cold mist beams. Since they are an exact replication of Frost's ice powers (minus icicle creation and ice healing) it is equal in strength to Frost's and also leaves traces of dark matter.
  • Chillblaine suit: After breaking out of Iron Heights, Mark wore a specialized suit while committing crimes as Chillblaine.[2]
