Quote1 The only way I could feel warm, the only way to melt the ice in my veins... was to kill. Quote2
Killer Frost src


Caitlin Snow was a young and bright scientist working for S.T.A.R. Labs assigned to an underfunded S.T.A.R. Labs Outpost #72 in the Arctic Circle, where the deceased researcher Dr. Louise Lincoln had been working on a Self-Sustaining Thermodynamic Ultraconductor Engine that could subvert the second law of thermodynamics in order to create perpetual motion. Caitlin became interested in continuing Lincoln's work, in spite of her colleagues warning her against it.

When Caitlin succeeded in finishing the S.T.U. engine, her colleagues turned on her and revealing themselves to be working for H.I.V.E., as they were expected to ensure that the engine was never made public in order to protect H.I.V.E.'s investments in the energy industry. Furthermore, they were also responsible for Lincoln's death, and they then proceeded in silencing Caitlin by placing her in the working S.T.U. engine. In a panic, Caitlin ripped out the wires for the engine's coolant system, consequently infusing her biological makeup with ice. As a result, she became a vampiric being who craved for heat, and killed the H.I.V.E. agents.

After carrying out her vengeance, Caitlin continued to search for other sources of heat; she attacked a Norwegian research camp and stole their helicopter to fly to her hometown of Pittsburgh, where she encountered and fought Firestorm. While fighting Firestorm, Caitlin discovered that Firestorm's powers can temporarily heal her condition, and devoted her time to seeking and confronting him. She soon learned about the Firestorm Matrix and attempted to recreate it.

At some point, she partook in a trial for Deathstroke. She asks if she will also go on trial since she joined the Justice League. They tell her she just has to read some books.

Powers

  • Unique Physiology: Her new state is very basic, almost primal. Her body is completely encased in permafrost. She is not made of ice but she generates organic ice-like cells which make up her changed genetics.[1]
    • Cryokinesis: She can generate ice spikes to spear her opponents, kill an ordinary human with her freezing kiss and/or create a ice storm powerful enough to freeze everything, killing multiple people.[1]
      • Heat Absorption: Frost is a so called "Heat Vampire", to stay alive, she must regularly absorb heat. The most efficient way to satiate this "hunger" is to absorb the body heat of others.[1]

Abilities

Weaknesses

  • Power Instability: Frost will die unless she regularly absorbs heat. This extends to areas of extreme cold for too long.
