Red Daughter

The unnamed clone of Kara Danvers came to exist when the original Kara utilized the Harun-El to go back in time in order to defeat Reign. She resides in Kaznia and is working with its soldiers on an unknown agenda.

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 clone of her. The clone, 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 clone continued her work under the watchful eye of the soldiers.

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

Personality
The clone seems loyal and obedient to the Kaznian soldiers, eager to train for their plans.

Powers

 * Kryptonian physiology: Normally, like all Kryptonians, the clone'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 the clone's 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: The clone's strength is enhanced under a yellow sun, enough to easily destroy powerful structures such as mountains.
 * Flight: The Clone’s is able to manipulate her own gravitational field to generate thrust and propel herself through the air while enhanced under the yellow sun.

Weaknesses

 * Kryptonite: Like all Kryptonians and the Original Kara, even while empowered, Kara (clone) 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 Kara (clone), but weakens her physical attributes, leaving her vulnerable to weapons and anything in general that can kill a normal human, but if she is exposed to it for too long, it will kill her.

Trivia

 * She's the second clone/duplicate of Kara Danvers, the first being Jane Doe/Bizarro.
