Killer Frost

In subsequent appearances, Lincoln joins the Suicide Squad, sells her soul to Neron to enhance her powers, and briefly enters a relationship with Effigy.

[14][15] During the Doomsday Clock event, Frost supports the "Superman Theory" and claims that the U.S. government gave Captain Atom, Firehawk, Moonbow, and Typhoon their powers.

In subsequent appearances, Snow seeks help from Firestorm and Martin Stein to cure her condition and joins the Suicide Squad and Justice League.

Her weakness is the need to absorb external heat sources to generate ice: although heat-based weapons such as flamethrowers only make her stronger, she can be imprisoned in cold surroundings such as being locked in a refrigeration truck or buried under a mountain of snow.

However, in recent stories she seems to have finally gotten it under control by only absorbing a tiny amount of heat from every person she touches, sparing them and leaving them otherwise unharmed.

The Caitlin Snow and Louise Lincoln versions of the character have, albeit inconsistently, demonstrated the ability to fly, either by riding Arctic winds or through an unknown manner of self-propulsion.

While the exact limits of her abilities have yet to be established, how much power Frost can channel at once seems to depend on how much heat she has absorbed and stored in her body.

She once managed to create an ice prism with her powers that converted Superman's heat vision into a bright burst of sunlight to defeat Eclipso.

Several adaptations of the villain have also depicted the Crystal Frost and Louise Lincoln incarnations as having basic skills in melee combat which they use in conjunction with their powers as well as impressive agility, being able to perform maneuvers such as leaps or cartwheels with ease.

[22] This version is Louise L'inconnue, a servant of Hugo Strange who is of French and German descent and gained her powers after her mother was killed and she was left to die in a well.

[25][26][27][28][29] In the fifth season, Caitlin discovers that her powers originated from her father Thomas' attempts to cure their genetic propensity to ALS.
