- Kryptonians don't surrender!
- — Supergirl src
Kara Zor-El was a teenager when Brainiac's robot army invaded Krypton. As Brainiac's troops attacked Krypton's main cities and slaughtered people and Brainiac abducted his chosen cities, her mother Allura In-Ze revealed Krypton was about to die because the planet's core was intentionally destabilized by Brainiac and set to explode. Nonetheless, her family planned to send her and her baby cousin Kal-El to another planet to ensure their survival. While Kara got in her rocket, Allura reminded her that a daughter of the House of El never gives up.
Kara's shuttle took off and flew into space alongside her cousin's right before Krypton exploded. Unfortunately, debris from Krypton's destruction crashed into Kara's shuttle, causing her to veer off course and become separated from Kal. Kara's rocket put her in suspended animation as she went on her trip.
Kara's rocket was found by Black Adam near Earth several decades later. Upon being taken to Kahndaq, Kara was taught by Adam that her baby cousin was now an adult who became the world's greatest champion. He gave her half-truths about the Regime, painting it in a positive light and depicting the Insurgency as dangerous and ill-intentioned people who removed her cousin from power.
Having successfully convinced her to be sympathetic to their cause, Adam and Nightwing sent Kara on a mission to rescue Wonder Woman from high security imprisonment on Themyscira. Though she found herself unable to lie about her mission, Kara's mission and mere presence excited a group of rebel Amazons who also sought to return Diana to her rightful position as Wonder Woman.  A war broke out between the rebels and the loyalists, but, thanks to Kara's intervention, Wonder Woman was successfully set free. Kara and the rebel Amazons then made their escape on a boat that Kara single-handedly pulled away from Paradise Island and towards safety. 
Supergirl joins Wonder Woman trying to break Superman out of Ryker's Island. After fighting with Firestorm, Batman arrives, agreeing to free Superman due to the losing battle against Brainiac. During this time, Brainiac's allies, the Society, attacks as well, where Supergirl fights and loses to Cheetah. After Wonder Woman defeats Barbara, she attempts to kill her, only to be stopped by Harley, who Wonder Woman stabs through the stomach with her sword. Appalled by this, Supergirl defeats Wonder Woman in combat, then goes to get Harley medical attention, saying that Kal can help her. Harely gives a weak chuckle, confusing Kara.
Meeting up with her cousin in the Fortress of Solitude, Superman he admits its unfortunate that Diana decided to deal with Harley now, and that Kara got in the way. Now seeing Kal for who he really is, Kara in fear attempts to leave the Fortress, fighting Nightwing and Black Adam before dealing with her cousin. After hearing that Brainiac has started his collecting of the planet's cities earlier than anticipated, the cousins put their differences aside, with Superman claiming they will talk later.
Superman and Supergirl are later seen trying to destroy Brainiac's ship, however neither are making headway, and Supergirl is digitized and becomes prisoner on the ship. After being freed by Batman, Kara discovered Kandor digitized among the collections of cities. Not long after, Supergirl is quickly recaptured and put in kryptonite restraints.
After Brainiac's defeat, Kara is freed by Batman, and discovers Kal has plans to use Brainiac's ship to further his control of the world. The heroes are divided with Kara siding with Batman, and attempts to reason with Kal once again, only to fall at his hands.
Kara's fate depends on which character the player chose after Brainiac's defeat. In the Absolute Justice time line, Batman defeats Superman, and depowers him with Gold Kryptonite lights before sending him to the Phantom Zone. Kara looks on, stating they're still family. Batman cheers her up, stating that she couldn't be held accountable for not knowing about Kal's real nature. Batman also states the world could use a new Justice League, with Kara as a member.
In the Absolute Power timeline, Superman defeats Batman and takes control of the ship. Kara is seen sitting in the red sunlight cell and introduced to the newest member of the Regime, a mind controlled Batman.
Possible Post-Brainiac Epilogue
This section of history takes place in a timeline outside that of normal Injustice: Gods Among Us history. Information here does not reflect the true history of neither the Injustice: Gods Among Us universe nor the Injustice: The Regime universe, and should not be seen as relevant to future sequels or comic adaptations.
"My hands still shake when I remember Brainiac's 'collection' of Krypton. I want to give the world he stole a second chance. But bonding with Brainiac's ship is too risky. I need a safer way to restore our cities. I'm so glad for the Justice League's help. Barry, Professor Stein - they've already taught me so much!
Everyday we get closer to reversing Brainiac's collection process. When we do, we'll pick the right star system. What Brainiac ruined will be reborn - Argo City and Kandor, twin cities, survivors. I couldn't save Kal-El but I will save our people."
- Kryptonian Physiology: Under the effects of a "yellow" sun, Supergirl possesses the same potential powers as an average Kryptonian. These include:
- Solar Energy Absorption: Under optimal conditions, this is the main source of Supergirl's super powers as they are contingent upon exposure to solar radiation from a yellow sun star system. Her biological make up includes a number of organs which lack analogues in humans and whose functions are unknown. It is believed that between one or more of these and her bio-cellular matrix, "yellow" solar energy is stored for later use. This allows for the use of these powers to fade when yellow solar radiation is not available instead of immediate failure.
- Heat Vision: Supergirl can, as a conscious act, fire beams of intense heat at a target by looking at it. She can vary the heat and area affected.
- Super-Hearing: Supergirl's hearing is sensitive enough to hear any sound at any volume or pitch. With skill and concentration, she can block out ambient sounds to focus on a specific source or frequency.
- Enhanced Vision: Supergirl's vision processes the entire electromagnetic spectrum as well as allowing vast control over selective perception and focus.
This umbrella ability includes the following:
- Electromagnetic Spectrum Vision: Supergirl can see well into most of the electromagnetic spectrum. She can see and identify radio and television signals as well as all other broadcast or transmitted frequencies. Using this ability, she can avoid detection by radar or satellite monitoring methods. This also allows her to see the aura generated by living thing.
- Telescopic Vision: This is the ability to see something at a great distance, without violating the laws of physics. Though limited, the exact extent of the ability is undetermined. In function, it is similar to the zoom lens on a camera.
- X-Ray Vision: This is the ability to see through any volume of matter except lead. Supergirls can see things behind a solid, opaque object as if it were not there. She can focus this ability to "peel back" layers of an object, allowing hidden image or inner workings to be observed. The exact type of energy perceived—such as x-rays, cosmic rays, or some other energy invisible to normal humans—is unclear. This ability perceives an ambient energy source though, it does not involve the eye projecting a concentrated, possibly toxic, beam to be reflected back from objects.
- Microscopic Vision: This is the ability to see extremely small objects and images down to the atomic level.
- Infrared Vision: Supergirl can see with better acuity in darkness, and to a degree in total darkness.
- Flight: Supergirl is able to manipulate graviton particles to defy the forces of gravity and achieve flight. This ranges from hovering to moving in any posture, in any direction.
- Invulnerability: Due to the interaction of her dense molecular structure and supercharged bio-electric aura, Supergirl is nigh-invulnerable to extreme energy forces. In addition, her extends this protection against toxins and diseases.
- Superhuman Stamina: Supergirl is able to maintain continuous strenuous physical action for an indefinite period of time. This based on her body converting yellow solar radiation directly to energy, but is limited by physiological and psychological needs to eat, drink, and sleep.
- Superhuman Strength: Supergirl's strength is augmented by yellow solar radiation interacting with the greater than human density, resilience and biological efficiency of her musculature. Her strength is more an act of conscious will on energy fields than actual physical strength. It is this act of conscious will that enables her to perform physical feats that are beyond the mere application force, such as moving a mountain top without said rock crumbling under its own mass.
- Superhuman Speed: Supergirl is able to move at incredible speed by sheer force of will. This extends to her perceptions and allows for feats such as catching bullets in mid flight as well as covering vast distances in little or no time.
This also confers:
- Super-Breath: Supergirl is able to create hurricane force winds by exhaling air from her lungs. She can chill the air as it leaves her lungs to freeze targets. She can also reverse the process to pull large volumes of air or vapor into her lungs.
- Kryptonian Physiology: Under the effects of a "yellow" sun, Supergirl possesses the same potential weaknesses as an average Kryptonian. These include:
- This version of the character is exclusive to the continuity of the Injustice: Gods Among Us video game series and is an adaptation of Kara Zor-El/Supergirl. The original character was created by Otto Binder and Al Plastino and first appeared in Action Comics #252.
- Supergirl is voiced by Laura Bailey.
- Supergirl's gear includes a "Midvale Safekeeping", referencing her Earth hometown, and a "Black Kryptonite Protector", referencing a story arc where Lex Luthor exposed her to black Kryptonite.
- Several of her attacks reference Supergirl's storylines or supporting characters: "Streaky Streak" (a reference to her pet cat), "Amazonian Charge", (referencing the fact that Post-Crisis Supergirl was trained by Wonder Woman and was an Honorary Amazon), "Elseworld's Finest" and "Hail and Farewell" are some few examples.
- During one of their pre-match dialogues Atrocitus suggests her to join the Red Lantern Corps, a reference to the Supergirl: Red Daughter of Krypton storyline, where her great sense of rage drove the attention of a Red Lantern Ring which attached to her until she managed to remove it while near the Sun.
- Kara was a Raoist.
