Red Daughter

"Supergirl acts on her emotions. It's selfish, ugly. I will not be her. I will be me. I will be disciplined. I will follow you and destroy her."

- Red Daughter to Lex Luthor

Red Daughter, originally codenamed Snowbird, is a copy of Supergirl who came to exist when the original Kara went back in time and utilized the Harun-El to defeat Reign, materializing after a torrent of dark magic hit Siberia. She resides in Kaznia and is working with its soldiers and Lex Luthor in a plot to defeat the USA and resurrect the glory days of the Soviet Union. While undercover in the U.S., she used the name Linda Lee.

Biography
As Kara Danvers used some Harun-El to transport herself, Samantha Arias and Reign to Juru to defeat the Dark Kryptonian, the stone released a torrent of dark magic, which soon ventured into the Siberian Border and materialized into a copy of Supergirl. The copy, clad in a blanket, ventured forth through the snow and approached a group soldiers at the border.

5 months later, Kara's copy was seen punching through the rocky walls in a secret mine in the mountains of Southern Kaznia. Presumably, her strong punches caused an earthquake which created landslides above and destroyed part of a railroad track. After Supergirl saved a Kaznian train from being derailed, the copy continued her work under the watchful eye of the soldiers.

When the U.S.-based anti-alien hate group known as the Children of Liberty released Kryptonite into the Earth's atmosphere, Kara's copy was placed into a special confinement cube to protect her. A couple of days later after L-Corp nanites were used to purify the atmosphere of Kryptonite particles, she was released and resumed her training.

Personality
"Let them hate, as long as they fear"

- Red Daughter

As Snowbird, she grew to be loyal and obedient to Kaznian Military, eager to train for their plans, if somewhat emotionally detached and focused entirely on training, Red Daughter has various fragments of the original Kara's personality, her compassion for others, her dislike for injustice, and her connection to Alex (however, her only memory is of her name, a fact which was abused by Lex Luthor) Red Daughter has a dislike for the greed of humanity, displaying it openly at most times.

Red Daughter is proven to be introspective, wondering about her life and purpose, and analyzes all information she gets, as such, after being shown Kara Danvers' apartment by Lex Luthor, she did not discard the knowledge she gained, but decided to further study Kara's life, her passion for justice, the love for her friends and family, she also tried to contact Lena Luthor, but their discussion was cut shot by Eve Teschmacher, who was working at L-Corp under Lex's orders. During her stay in the United States, she has found deeper understanding of humanity, both it's dark and light sides, and started to hate Americans much less than before, which could jeopardize Eve and Lex's plans.

This has led them towards staging an American attack on Mikhail from Kaznia, enraging Snowbird once again, afterwards, she ended up in a conflict with Lex, engineered entirely by him to gain her trust in the end, with a blood transfusion with mutated Harun-El cells, saving her life, feeling that she owed to Lex, Snowbird has rethought her role, deciding that Kara Zor-El acted entirely on emotion and was thus weak and blinded to the world's real problems. She pledged herself entirely to Lex's mission and he awarded her with the Red Daughter's suit, christening her "his Red Daughter".

Powers

 * Harun-El mutation: As a product of the Kryptonian artifact Harun-El, Snowbird was created as a materialized alternate persona of Kara Zor-El. After suffering from Kryptonite poisoning weakened her immune system, Snowbird was given a blood transfusion from self-mutated Lex Luthor, introducing his Harun-El anti-cancer cure to her immune system.
 * Power bestowal: While having a shock and in an attempt to save her, she is electroshocked at full charge, and the shock was so powerful, it went through overseas and affected some drugs, giving the user of the drugs strange abilities.
 * Kryptonian physiology: Normally, like all Kryptonians, Red Daughter's capabilities are no greater than a normal human of her physical conditioning. However, once charged by the energy spectrum of a yellow sun, she becomes able to perform various inhuman feats.
 * Solar energy absorption: While her powers are dependent on the energy spectrum from a yellow sun, her body is able to constantly and passively absorb such energy while exposed to it, essentially keeping her reserves fully charged near-constantly. Direct exposure to the light of a yellow sun will also accelerate her recovery from any injuries she does manage to sustain.
 * Super strength: Red Daughter's strength is enhanced under a yellow sun, enough to easily destroy powerful structures such as mountains.
 * Heat vision: By concentrating every solar energy reserve she has in her body, Red daughter can emit blue energy beams of variable intensity and temperature from her eyes.
 * Flight: Red Daughter is able to manipulate her own gravitational field to generate thrust and propel herself through the air while enhanced under the yellow sun.
 * Invulnerability: Red Daughter is invulnerable to most harm while enhanced under a yellow sun. She is proven to be completely bulletproof.
 * Super hearing: Red Daughter has super-sensitive ears that can perfectly pick up sounds from miles away and even through structures.
 * Super speed: Red Daughter possesses the ability to move at hypersonic speeds; both through flight and on foot.

Abilities

 * Expert hand-to-hand combatant: Having receiving several months of training from the Kaznian army, Red Daughter is an extremely skilled hand-to-hand combatant.
 * Genius-level intellect/Economics/Politics: Red Daughter is very intelligent, thanks to both her natural intelligence and to Lex Luthor's training. She is an avid reader of literature, a student of economics, politics and languages. Red Daughter studied books on economics, namely those written by Karl Marx, she has also studied books on politics.
 * Skilled deceiver/Acting: Red Daughter is skilled in the art of deception; as she managed to successfully portray herself as Kara Danvers to both Alex Danvers and Lena Luthor respectively, with little effort, as neither Alex or Lena suspected that she was not the real Kara.
 * Bilingual: Red Daughter is capable of fluently speaking Russian and English. Red Daughter can also speak these languages at a native level as well; effectively changing her thick russian to an american one.

Weaknesses

 * Kryptonite: Like all Kryptonians, Red Daughter, even while empowered, is vulnerable to the exposure of Kryptonite, a radioactive mineral from Krypton. Depending on the nature of the said Kryptonite, it will cause a different adverse affect on her;
 * Green Kryptonite: Green Kryptonite not only physically hurts Red Daughter, but also it weakens her physical attributes; making her equivalent to that of a normal human. If she is exposed to enough green kryptonite for too long, it will eventually kill her.
 * Naivety: As a newly-created being with no actual life experience, Red Daughter is quite naive, making her easy to manipulate. Lex Luthor took advantage on this and manipulated her into hating Supergirl and becoming a weapon under his command.

Former weaknesses

 * Severely weakened immune system: After Red Daughter was exposed to green kryptonite, it severely weakened her immune system, eventually leading her to collapse. However, after she got a blood transfusion from the newly turned meta-human Lex Luthor, she was cured and her immune system was restored to it's normal state.

Equipment

 * Suit: Lex Luthor made a suit for her to wear as Red Daughter.
 * Supergirl suit: Red Daughter wore a replica of Supergirl's suit when she attacked the White House. It is unknown where she got it from.

Behind the scenes

 * Additionally, in the main DC Comics continuity, Linda Lee was the first identity Kara Zor-El used on Earth in the pre-Crisis version of the multiverse.

In particular, Mr. Mxyzptlk affected reality to turn Superman into Kaznia's own "Red Son", while Supergirl became a superstar celebrity with Mxy himself as the producer.
