Frost made her first appearance in Mortal Kombat: Deadly Alliance as an apprentice to Sub-Zero, taking the character archetype of the overly ambitious fledgling. Her dedication to fighting and learning is overshadowed by her arrogance and hostility towards anyone she perceives to be greater than her, including her own master, whom she refers to as sifu (a Cantonese term for a master or teacher), and Sonya Blade.
Frost possess freezing abilities similar to that of Sub-Zero, albeit in a minor scale. Proof of this is in the both their abilities to form solid weapons by freezing surrounding water vapor: while Frost can create small daggers, Sub-Zero is capable of creating a sword.

After Sub-Zero became Grand Master of the Lin Kuei clan, he held a tournament in order to recruit strong warriors. The victor was Frost, whose exceptional skills impressed him. Breaking Lin Kuei tradition, Sub-Zero took her as his protegé and trained her personally. With his assistance, her ability to focus her freezing power increased. However, as her skills grew, so did her arrogance.

When Raiden requested Sub-Zero's assistance in defeating the Deadly Alliance, Frost's training was cut short. Sub-Zero brought her along with him for assistance, hoping at the same time she would attain perspective and enlightenment through the experience of actual battle. After meeting with the other Earthrealm warriors (one of which was Sonya, who did not get along with Frost), she accompanied Sub-Zero into Outworld. It is revealed in the MK Deadly Alliance Konquest mode, that Sonya had a brief fight with Frost in which the latter would have lost had the fight not been stopped by the other fellow warriors. It seems Sonya never trusted Frost and was suspicious of her intentions in addition to the fact that she despised the arrogance of the new Lin Kuei warrior.
Once there, her true intentions for joining the Lin Kuei became apparent. Desiring to become Grand Master of the clan herself, she immobilized Sub-Zero with a freezing blast and tore the Dragon Medallion (an artifact which enhanced Sub-Zero's abilities, as well as the symbol of Lin Kuei leadership) from his chest. Without the strength and discipline required to control the medallion's power, she was consumed by her own freezing ability, seemingly killing her.
Seemingly forgiving her for her betrayal, Sub-Zero searched for a suitable place to bury her remains. He discovered the ancient ruins of a holy structure erected by the long-lost race of Cryomancers. After careful study of the building, Sub-Zero came to believe that both he and Frost were their descendants, and so laid her body to rest in a sarcophagus before leaving.
However, during the events of Mortal Kombat: Deception, Frost awoke some time after Sub-Zero's departure, miraculously alive after all. Realizing she was still in Outworld and that Sub-Zero had left her for dead, she swore to make him pay. Frost then returned to the Lin Kuei temple, hearing Sub-Zero was still in Outworld and hoping to kill him. Later, she entered a state of delirium, seeing Sub-Zero everywhere. Frost dispatched many Lin Kuei members while in this state until Sub-Zero returned. He deep froze Frost into an ice coffin and placed her in the chamber of the fallen Lin Kuei, sealing it later with an ice wall.

Later, as the events of Armageddon begin, Taven revived her from her ice coffin. Frost, still seeing Sub-Zero everywhere, attacked him, but was still defeated by Taven. After the fight, she realized Taven is not Sub-Zero, and left the chamber to parts unknown.
