Louise Lincoln

== Biography ==
=== Early Life ===
Louise Lincoln did not have a happy childhood, to put it simply. After her father died in a car accident when she was young, her mother fell hard into substance addiction, leading her to live with her grandfather, retired Blackhawk pilot Andrew Lincoln in Appleton City, Colorado. Lincoln himself was riddled with guilt over the loss of his lover, Zinda Blake. Andrew was a negligent and abusive caretaker, leading Louise to mostly fend for herself.
Luckily for her, she had a guardian angel in the form of the local librarian, Crystal Hudson, who would offer Louise food and sometimes even a place to stay. She also nurtured her brain, recommending her books and later convincing her to apply for scholarships to get her out of her situation. With Crystal’s help, Louise graduated high school a year early. She left home to Ivy University on a decent scholarship and never looked back.
At Ivy University, she studied under Doctor Martin Stein, and grew completely smitten with him. When he rejected her advances, she was devastated. However, her brilliance was seductive in its own right, and Stein continued to help her with her studies.
She went on to graduate school, where she studied even closer under Stein, but he always kept her at arm’s length, favoring another student, Ronnie Raymond, who he gave preference to in several considerations - even employing him as his teacher’s assistant.
Frustrated when Martin offered Ronnie an internship position at STAR Labs, Louise decided to pursue other education for her doctorate - opting for a practical training program in Antarctica, at a research station called Mohole-1. There, she worked with a team of scientists replicating Victor Fries’ work, creating the Thermafrost Freezer, believing it could perfect cryo-freezing and utilizing the research to find a cure for MacGregor’s Syndrome.
However, Louise was unaware that her fellow researchers were undercover sabotage agents assigned by HIVE. After stealing the schematics from her, they locked her in the containment unit and sabotaged it, before leaving the base and stealing all the transport vehicles.
The extreme temperatures activated Louise’s metagene and gave her cryokinetic powers. She escaped from the chamber and walked through the Antarctic wilderness alone to finally reach a helicopter, where she hitched a ride back to the United States.
=== Killer Frost ===
In the US, she found herself in the care of STAR Labs, specifically with Stein and Raymond. Angered at the irony of this, she went AWOL in the middle of the night and disappeared. However, on the way out, she made sure to take note of the security systems, and sold the information to corporate saboteurs, resulting in the destruction of the Particle Accelerator.
She soon discovered that in order to survive and remain conscious, she had to consume massive amounts of heat. She spent a few years on her own, seeking out heat sources, including destroying a nuclear engine at a Norwegian research facility. While laying low, she was contacted by Gorilla Grodd, who offered to help her with her ailment if she helped his "Injustice Gang" kidnap the Justice League.
She quickly agreed to the deal. Going by the alias of Killer Frost, she worked with Felix Faust, Photon, Multiplex, Mirror Master, Fatality, and Clayface to successfully capture the Justice League and transport them to Roanoke Island, where Grodd and Faust planned to execute a body-swapping ritual to deduce the League’s identities. However, they were attacked by the second class of Leaguers. In order to escape, she froze Photon’s feet to the ground and ran off.
She would turn up a short time later in Central City, this time attempting to steal Mick Rory’s heat gun from CCPD, where it was in evidence lock-up. While the Flash was off dealing with Justice League business, his new ally in the form of Firestorm was there. In their ensuing battle, she realized she would be unable to win, and so she faked an overload of energy and lowered her body temperature enough to convincingly appear as if she were dead.
While authorities tried to contact her grandfather, Louise quietly escaped from the morgue, which would be blamed on Intergang’s group of metahuman graverobbers and managed to evade capture for a brief time. She traveled to Fawcett City to stake out Sivana Industries. However, Thaddeus Sivana noticed her, and instead offered her a position with them.
=== Frostbite ===
Sivana helped her create her “Frost Pendant”, which supplied her with a steady amount of thermal energy, returning her skin to its former color. But, in return, she acted as a corporate saboteur and research consultant for his projects. She remained under Sivana’s rule for years, forever indebted to him.
During her time at Sivana Industries, she got back into contact with her old librarian, Crystal Hudson, and discovered that she had MacGregor’s Syndrome and would soon perish. Louise got in contact with Victor Fries and they worked with Sivana to develop a cure for the disease, finally saving Crystal’s life.
As repayment, Crystal got Louise a job as a science teacher at the local high school, with the faked identity of Katie Lincoln. This appeared to be Louise’s shot at redemption, as she began living a nice quiet life, while occasionally pitching in to Sivana’s projects - however, it would not work out that way for her. 
In 2016, as the Justice League was shut down, Sivana created a fake superhero group based out of Dakota City called the Sivana Syndicate, and asked Louise to join under the alias of Frostbite. Fearful he would deactivate her pendant if she refused, Louise agreed, and joined the team, where she helped kidnap several individuals infected by the Bloodlines Parasite and capture Victor Stone. She also began dating fellow Sivana Superhero Martin van Wyck aka Effigy.
While holding Victor hostage inside a STAR Labs facility, Louise was attacked by visiting scientist Caitlin Snow. Snow actually drew blood, prompting Louise to create an icicle and stab her through the heart. As a ragtag group of Justice Leaguers arrived to attack, Caitlin rose up, no longer bleeding from the heart, and wielding her own cryokinetic powers and attacked Louise, destroying her pendant in the process.
Their fight sent Louise into a coma, for real this time, causing her to be placed in cryogenic stasis and placed in the care of STAR Labs, who began searching for a cure to her disease, with Caitlin Snow helping with research from her hometown of Central City.
