Kara Zor-El is the daughter of Superman's uncle Zor-El and his wife Alura. Kara is actually older than Kal-El (Superman); she was a teenager when he was a baby. When Krypton was attacked by Brainiac, he took Kandor with him, while Kara and her parents remained in Argo. After Brainiac's attack, her father created a force-field around Argo using a Brainiac Probe. When Brainiac came to consume Argo City, her parents had no choice but to send her in a rocket headed for Earth. However, her rocket was caught in a large kryptonite-encrusted meteor and she arrived on Earth years after her cousin did.
After some initial confusion, Kara was found by Superman and trained by Wonder Woman. She was captured by Darkseid, and after being brainwashed, attacked her own cousin. Superman defeated her and returned her to Earth, where he faked her death so Darkseid would not come looking for her.
She then assumed the role of Supergirl. However, she felt out of place, not sure where she really belonged. Kara was uncomfortable with her cousin's overprotectiveness, and she could not hang out with her Earth-Two counterpart Power Girl since their powers went haywire whenever they touched. She found kindred spirits in her other "cousin" Superboy and fellow alien Starfire.
Kara's self-discovery was interrupted when Lex Luthor used Black Kryptonite to split her into a good Kara and an evil Kara. The evil Kara stated that she was sent to Earth by Zor-El for the sole purpose of killing the infant Kal-El. Zor-El had devised a special crystal that would influence her personality as she traveled to Earth, making her "innocent", thus creating the good side of Kara's personality. However, the good side became dominant.
At the climax of the struggle between the two Karas and the Justice League, the good Kara urged Wonder Woman to use her golden lasso of truth to bind the two together and ask: "Who is Kara Zor-El?" The two Karas fused back into a single good Kara, who decided her past was not important and acknowledged Batman, Wonder Woman, and Superman as her foster parents.
Supergirl joined Donna Troy and other heroes to help prevent a coming crisis. While in deep space, Kara was struck by an altered zeta-beam and disappeared.
Supergirl and the Legion of Super-Heroes
Kara re-appeared in the 31st century. She was revered as a member of the Superman family. Upon her arrival, she concluded that she was "dreaming" the Legion and that the 31st century wasn't real. Saturn Girl, attempting to learn more about how Kara arrived in their era, scanned Kara's mind and found a particularly vivid memory -- that of the Zeta-Beam accident.
The Legion hypothesized that Kara was rationalizing her fantastic existence by believing her life was a dream. In a relatively short period of time (due to suspended animation):
- She lost her planet.
- She lost her parents.
- Arrived on Earth to find her baby cousin grown up and a legendary hero.
- She discovered her extraordinary powers and quickly reached the status of "living legend."
- Found herself inexplicably thousands of years in the future.
To complicate matters, every time Supergirl wanted something to happen in her supposed dream world, it happened. For example, when told she couldn't become a full member because the Legion was out of flight rings, one was immediately sent to her from Brainiac 5.
She had a few adventures with the Legion before Brainiac 5 came close to a means of returning her to the 21st century. He invented the Chronexus (a time window) that she and some of the other Legionnaires viewed various parts of Superman's history (including references to another Legion). Brainiac 5 secretly worked with Sev Tcheru to perfect the Chronexus technology by making it a real, but limited time machine. It only worked one way, and only once. When this was revealed, Saturn Girl convinced Kara that she should go back to her native era. Sev Tcheru wiped out Kara's memory of the Legion right before she went, as knowledge of future history was considered dangerous.
One Year Later
One Year (and one month) after Infinite Crisis, during World War III, Kara returned, only to find Superboy dead and Superman powerless. Feeling alone, she eventually started a relationship "no hero would condone". She also became Metropolis' protector along with Booster Gold and Supernova.
Soon after, she assumed the identity of Flamebird to fight crime in Kandor with Power Girl as Nightwing. They opposed a religious cult based around warped versions of Superman's earlier appearances in Kandor. Kara also believed the key to Argo City, her home town, lied somewhere in the city. Supergirl and Power Girl found themselves battling the Saturn Queen and Ultraman (posing as Superman), villains who had established themselves in Kandor. At the climax of the struggle, Supergirl unexpectedly left (with her comrade in tow). Since she did not consult with Power Girl about the timing of their exit, the two parted on somewhat strained terms. Note: This version of Kandor was actually just a psychic manifestation created by Saturn Queen. The real Kandor was not discovered until quite some time after this event.
Kara re-established herself on Earth, attaining financial independence after selling an item of Kryptonian technology that would completely "heal" anybody who used it to Batman for his own personal use at the price of one million dollars. With this money Kara, purchased her own apartment.
Kara attempted to develop familial ties with the Kent Family, who were still mourning the loss of Superboy. During a visit, Kara took one of Superboy's's trademark black t-shirts and gave it to his mourning girlfriend, Cassie Sandsmark, a.k.a. Wonder Girl. From there, Kara and Cassie forged a close friendship.
She also developed a close relationship with former-villain Captain Boomerang II. Owen clearly wished to date Kara, but she instead saw him as a big brother of sorts.
In an attempt to create a secret identity, Kara started going to high school under the name Claire Connors, a teenage girl from Kansas. Kara used a wig, glasses, and plain clothes to become "Claire." Her attempts to assimilate failed because she was unable to connect with the other students, and she dropped out after a week or so, due to cruel classmates.
As a favor to Captain Boomerang, Supergirl was granted an "audition" with the Outsiders. Having encountered the group once before, she had a crush on team leader Nightwing. She even stole a kiss, her "first true one", from Nightwing during their first encounter. The members of the Outsiders were all very suspicious of her. They believed she was using lethal force against criminals, but she was acting at super speed to disable them. She also broke the leg of a passenger on a cruise ship, who was really Metamorpho in disguise. She used x-ray vision to detect that the passenger was Metamorpho, and she was upset that the Outsiders decided to test her rather than tell her all the details and trust her. As a result, she decided to not join the team.
She met the new Terra and the two fought together to defeat a rogue Empathosaur.
Around this time, Kara met a new teenage super-hero, Power Boy. The two first met while rescuing hurricane victims in Mexico, and again later in Hollywood where they teamed up to fight two villains known as Gakidou and Sakki. Afterward, she began dating Power Boy (without telling Captain Boomerang).
A series of haunting half-memories of her past showed Zor-El subjecting an unwilling Kara to grievous experiments to enhance her powers; in fact, when badly injured by Batgirl (Cassandra Cain) in an artificial red-sun environment, Kryptonian Sunstones sprouted from her body, healing her and impaling her foe.
Kara accompanied Hal Jordan on a mission to the casino world of Ventura. She assisted the Green Lantern partly out of a desire to see more of the universe and partly in order to avoid a lecture about responsibility from her cousin. Her personality was slightly different from normal, as she appears to be quite flirtatious and playful with Hal, but when he politely rebuffed her advances, she entered a gladiatorial contest dressed in a pink dress and pigtails. The ploy turned out to not only be a response to Hal's comments, but also a clever ruse designed to flush out their prey.
Returning to Earth after her mission with Hal, Supergirl renewed her relationship with Power Boy. Power Boy revealed that he loved Supergirl so much that he was obsessed with her. After Kara was about to visit Owen in the hospital, Power Boy immediately stopped her and decided to go through this with violence, forcing him to turn on Supergirl. Power Boy was revealed to have been born on Apokolips.
Later when Kara found herself in deep space and near death, she saw a vision of her father, Zor-El. He then explained to her that she was remembering things wrong, so he needed to retell her why he did what he did before she left Krypton. He started by explaining that the Phantom Zone was inhabited by some sort of ghostly life. These beings were angry about being removed from their home by the projector and took out their anger by possessing various people who lived on Krypton. Zor-El then discovered that the only way to destroy the phantoms was with Kryptonian Sunstone. He implanted sunstones into her to make her immune to possession by the Phantoms. Shortly afterward, the students at the school Kara went to on Krypton were possessed by these Phantoms and they were forced to kill them all with sunstone. For this, the Kryptonian Science Council had decided that Zor-El, Kara, and Alura should be sentenced to exile in the Phantom Zone. However the final quakes before Krypton's destruction interrupted this before the sentence could be carried out. Then, in the present day, Kara found herself back on Earth and saw the Phantoms there.
Kara was then assaulted by hundreds of Phantom-possessed humans, including Wonder Girl, who forced Kara to admit all the dark secrets that she has been denying since arriving on Earth. Disgusted with Kara, Wonder Girl released her. Kara then flew to the Batcave in the hopes that Batman might be able to help her. Unfortunately, the Phantoms had possessed him, and he had sealed himself inside the cave. Before Kara could try to break her way inside, Robin who was also possessed, blocked her path. He provoked Kara into hitting him, and she accidentally stabbed Robin with a sunstone. This surprisingly did not kill nor even mortally injure him, but instead freed him of the Phantom Ghost. Robin, who had apparently been keeping tabs on Superman since the sun went red (using a Batsuit loaned to Superman since his powers were gone), then gave Supergirl directions to locate Superman in Metropolis. When she reached Metropolis, she discovered that the phantoms were coming out of Superman's body.
Once reunited with her cousin, Kara admitted everything. Clark, who has been going mad from the Phantoms that were leaking out of him, begged her to kill him and free their adoptive homeworld. Before any actions could be taken, a Pre-Crisis version of Supergirl appeared and attacked Kara, cheerfully taunting her with accusations of imperfection and inadequacy during their battle over Metropolis.
She soon discovered that all of these events were really the machinations of Dark Angel, including the Phantom-infested Earth, Cassandra Cain's attack, and Kara's direct encounter with her father. All of these were part of Dark Angel's twisted "test" to determine her validity in the Multiverse. Acting under the auspices of one of the Monitors to identify post-Crisis "anomalies" who threaten the Multiverse, Dark Angel had become personally invested and then obsessed with proving Kara's status as an anomaly through increasingly brutal means. The Monitor appeared and chastised Dark Angel harshly. He asserted that Kara was, indeed, this universe's Supergirl, and apologized for Dark Angel's excess. After stating that Kara's tragic memories of her journey to Earth were real, the Monitor departed with his employee, leaving Kara in deep space with her Kryptonian abilities apparently restored and no outward sign of her sunstone implants.
Kara then met the reborn Pariah, who warned her of a "Great Disaster" that was coming during which she was destined to play a role. Kara then returned to Earth where she sets about correcting some of her past wrongs, apologizing to Boomer for leading him on, repairing her friendships with Cassie and Sarah (a girl she met during her brief time in High School) and dealing with her cat Streaky. Though she attempted to apologize to Power Girl for her actions in Kandor, Power Girl said she couldn't trust her and challenged Kara to fix things with Clark. After spending fifteen minutes outside Lois and Clark's apartment deciding what to do, Lois invited Kara inside, where she and Clark embraced. Her actions over the past year forgiven, Kara raced her cousin to the Fortress of Solitude.
Later, when Wonder Girl confided in Kara some of her personal problems, they discovered that the Amazons of Themyscira have invaded Washington, D.C. as part of the events of Amazons Attack. Because of the McCarran Internal Security Act, implemented by the U.S. President, Wonder Girl's mother and a friend of Supergirl's, named Alison, were held at an internment camp. As they tried to storm the camp and free the women, they were stopped by the Teen Titans, and told by Robin that negotiation would be a better solution. Consequently, they flew to Washington D.C. and spoke with Queen Hippolyta, who told them that negotiations were impossible, since the President was safe on Air Force One. Agreeing to bring the U.S. leader to the Amazon Queen, the two girls blocked the path of Air Force One and threatened to bring the plane down if the President did not come with them.
Kara received membership with the Teen Titans shortly thereafter, though her tenure with the Titans was extremely brief. Although no longer a member, Kara participated in several adventures with the young heroes.
Kara met two time-travelers from the 30th century named Val Armorr and Una. Val and Una were members of the Legion of Super-Heroes, albeit from an alternate future timeline than the Legion that Kara was familiar with. At the Nebraska/Colorado border, Supergirl assisted the Legionnaires in battling a cybernetic powerhouse named Equus. Equus attempted to destroy Supergirl by battering her with a railroad car, but Kara proved that she was in fact "more powerful than a locomotive". At the conclusion of this debacle, Supergirl, Val and Una parted company, but their meeting prompted something in Supergirl's mind that reversed Brainiac 5's previous mind-wipe. She now recalled all of her adventures from the 31st century, but was still uncertain if these things actually happened, or it was all just a dream.
Supergirl then assisted Superman and the Green Lantern Corps in tracking down an invading alien armada back to their home galaxy. Kara made use of tesseract technology to follow them, but ultimately a solar flare distracted her senses and she was unable to determine the aliens� point of origin. She returned to her home to report her failure, but Superman was still proud of her efforts.
Soon after, Supergirl encountered a villain who would prove to be her greatest nemesis � Reactron. Reactron claimed to have the power of a star inside his containment suit, and he unleashed a massive attack of atomic energy that threatened to destroy Metropolis. Supergirl fought against him and lost in the initial throwdown. Supergirl came back for round two and determined that Reactron's power source originated from a circular disk inside his chest cavity. Supergirl tore the device from his containment suit and Reactron was defeated.
Way of the World
In the aftermath of Reactron's attack against Metropolis, Supergirl learned about a boy named Thomas Price. Thomas was 11 years-old and dying of cancer. Supergirl made a promise to him that she would save his life � a promise that provoked strong opinions from not only his parents, but from Superman as well. Superman warned her against pursuing this course of action, for even though they are powerful heroes, nobody can stave off death. Supergirl was undeterred however, and continued in her quest to find a cure.
She sought out Mitchell Shelley, the Resurrection Man, whose nanite-infected blood enabled him to literally resurrect himself from the point of death. Supergirl wanted to use Shelley's blood to cure Thomas, but by the time she returned to Metropolis with him, she was too late. Thomas Price was dead. Supergirl refused to accept this. She even tried using the tesseract technology she acquired from the previous mission to alter the timeline so she could save Thomas' life, but even this was not enough. In vain, she still tried using Shelley's blood to revive Thomas, but this too failed.
Supergirl then teamed up with former Young Justice member Empress to take down Clayface and later a man named Eddie Rose. Rose was a survivor of Superman's fatal battle agains Doomsday, but the experience left him an embittered parapalegic. He wanted to turn public opinion against super-heroes, so he kidnapped Empress' family, forcing her to bait Supergirl into a trap. Supergirl was able to resist Empress' reluctant efforts to brainwash her, and together they were able to stop Rose and rescue Empress' parents.
After a series of unfortunate mishaps, lapses in judgment, and an article written by Cat Grant titled "Why the World Doesn't Need Supergirl", Kara decided that she should scale back her actions as a full-time super-hero. At the suggestion of Lana Lang, Kara adopted a civilian identity as Lana's niece and began calling herself Linda Lang.
World of New Krypton
Vril Dox, the original sentient computer known as Brainiac came to Earth with the intent of assimilating the planet's culture and technology into his gigantic skull-ship. Superman fought and defeated Brainiac, and in so doing, discovered the miniaturized Kryptonian city of Kandor. It had always been believed that Kandor was destroyed along with the rest of Krypton, but in truth, Brainiac had visited Krypton prior to its destruction, miniaturized the city, and secured it within a special containment tube inside his ship. With Brainiac's defeat, Superman liberated more than 200,000 Kandorians. These Kryptonians were restored to their normal size and their home city was transplanted to the Arctic Circle, where it was christened New Krypton. Among the survivors were Supergirl's parents, Zor-El and Alura.
Supergirl was overjoyed to discover that her parents were still alive. Her father explained that their original home, Argo City, had likewise survived the destruction of Krypton, but was later assimilated by Brainiac and merged with Kandor. Zor-El also revealed that many of Supergirl's prior perceptions of him were actually false memories as a result of prolonged Kryptonite poisoning. During the time that Supergirl was journeying to Earth, her ship was encased inside of a large Kryptonite meteor. The ambient radiation, while not fatal, was enough to unbalance her brain chemistry. Zor-El treated Supergirl and purged her system of the lingering Kryptonite particles.
The rest of the planet grew wary of the possible consequences of 100,000 super-powered Kryptonians now residing on Earth. In order to stave off a possible alien invasion, a secret government response group was put together known as Project 7734. The project was headed up by General Sam Lane (whom was previously believed to have been killed during the Imperiex War) and included several notorious agents such as Lex Luthor, Metallo, Reactron and a new Superwoman.
It was during this time that Supergirl suffered the greatest tragedy of her life. Under General Lane's orders, Reactron and Metallo invaded New Krypton. Armed with Gold Kryptonite (which robbed a Kryptonian of their powers), they systematically began slaughtering as many Kryptonians as they could find. Reactron murdered Supergirl's father, Zor-El.
As a result of the skirmish, Kara's mother Alura used Sunstone technology to literally uproot New Krypton from the planet Earth. The floating city was piloted into outer space and placed in geosynchronous orbit, directly opposite of Earth.
The United States government also took action as a response to Kryptonian violence. They passed a law, stating that all Kryptonians with the exception of Superman were no longer allowed to set foot on the planet Earth. This included Supergirl.
Supergirl went to live with her mother on the New Krypton planetoid. Alura still wanted revenge against Reactron for the murder of Zor-El and ordered Kara to return to Earth to bring Reactron to justice. Supergirl tried to keep her continued presence on Earth a secret, but she quickly earned the attention of Project 7734. She fought against Reactron for the second time, defeating him in a manner similar to how she stopped him when they first fought. She also fought against Superwoman, whom she discovered was actually General Lane's daughter, Lucy. The fight resulted in Supergirl rupturing Superwoman's battle suit, seemingly killing her.
Shortly thereafter, Supergirl celebrated her eighteenth birthday. As per Kryptonian custom, it was time for her to select a guild house for herself. After observing the way the other guilds worked, she elected to join the same guild as her mother - the Kryptonian Science Guild.
Nightwing, Flamebird, and Supergirl
After being teleported to an alley, Kara finds Chris Kent and Thara Ak-Var. Supergirl attacks Thara, for killing her father and trying to kill her. However, Chris stops Kara and tells her he is her cousin. The three are attacked by Guardian and the Science Police, for apparently killing Mon-El. Chris tries to tell Guardian that they did not murder Mon-El, but Guardian ignores him. The three manage to escape to Paris. Chris, Thara and Kara talk about what has happened. They then discover that the two sleepers they were fighting were Metallo and Reactron. However, they were then attacked by Squad K.
Escaping from Squad K, the three go to Lana Lang's apartment. They decide to get Lois's help in clearing their names. Chris and Lana go to find Lois while Kara and Thara stay in Lana's apartment. While waiting, Thara attempts to tell Kara what is wrong with Lana, but states it in a way that makes Kara angry. Meanwhile, Reactron promises General Lane he will kill Supergirl.
Kara, Chris, and Thara a.k.a. "The Metropolis Three" fight Reactron. Kara about to hit Reactron with her heat vision is instead hit by Reactron's gold kryptonite, stripping her of her powers temporarily. Thara jumps in front of Reactron before he can hit Kara again and is knocked out of the fight. Lois shows up to report the fight, noticing that the three are depowered and unconscious, engages Reactron in battle and wounds him by jabbing her pen in his neck. With Reactron about to kill Chris and Kara, Thara transforms in the Flamebird and easily defeats Reactron. Reactron reveals that General Lane was behind the sewer bombing to deepen the mistrust in Kryptonians. Kara decides to take Reactron back to Alura on New Krypton for punishment. Kara and Thara forgive each other.
Kara delivers Reactron to Alura. Alura has flashbacks of her time with Zor-El before Reactron killed him. She remembers how the Science Guild told her love is is simply a chemical response to external stimuli and therefore should be ignored. But she does love Zor-El. Back in the present, Reactron is standing trial. But before the verdict is announced, many Kryptonians burst into the courtroom, wanting revenge. Supergirl and Alura jump in to save Reactron, but in the skirmish, he is apparently killed. Supergirl decides to return to Earth. It is revealed Alura faked his death to torture him for information.

During Blackest Night, Kara and Alura visit Zor-El's tomb, only for a black power ring to seek out the body and turn it into a Black Lantern. Kara and her Black Lantern father fight and with Alura's help, knock him out of the city. Alura has a shield placed over the city so no one can leave or enter the city.
Kara is talking to Lana about her illness. Kara figures out that the illness is nothing the doctors in Metropolis can figure out. The Inspector calls Kara and the two fight Silver Banshee. Kara grabs a box and is transformed into SuperBanshee. Meanwhile, Lana has collapsed and is bleeding. The spirits that have possessed Supergirl are upset with the Silver Banshee. The Inspector cuts a coin from his hand to stop the Banshee spirits and Supergirl breaks free from their control. Silver Banshee then eliminates the disembodied clan spirits by screaming their name. Kara rushes to the hospital as Linda Lang just as Lana is pronounced dead. Linda goes to see the body and sees Lana encased in a chrysalis. Lana's condition is somehow the result of her time as the Insect Queen.
In Metropolis, Supergirl is captured when the hospital is engulfed in a massive cocoon and an army of humanoid insects emerge. Once she is freed by Gangbuster, Linda conspires with him and Kimiyo Hoshi to infiltrate the cocoon, rescue the hostages, and find out who is behind the invasion. After being ambushed and knocked out, Linda awakens bound and gagged at the feet of Lana, who has once again reverted back to her Insect Queen form. Insect Queen informs Linda that during her last encounter with Lana, she embedded a piece of her DNA within her in an attempt to retake her body. The two women engage in a drawn out battle, with Linda eventually expelling the Queen from Lana's body through the use of an advanced Kryptonian machine. After Lana is cured, Linda informs her that she is leaving her home, feeling betrayed about Lana's unwillingness to share her illness. Back at Project 7734, Lucy Lane is seen to have been resurrected and is an amalgam of "all" the alien races whose powers were in the Superwoman suit, with all of their powers and weaknesses. Lucy kills the physician with an electric blast and says she is ready for duty.
Last Stand of New Krypton
Brainiac is unleashing his robot troops into New Krypton and the Kryptonian citizens rise up to fight the drones. Zod, without hesitation, fires the Global Defense Cannons at Brainiac's ship, but only manages to kill the innocent Kryptonians in the way. Kal-El, furious at Zod for killing the citizens without remorse, changes into Superman. He then manages to pass the force-field and enter Brainiac's ship. Supergirl fights several of the probe bots in order to protect her mother. She is attacked by a probe, but is saved by Superboy, Mon-El, and The Legion of Super-Heroes. Kara takes them to Zod and they explain that there are other cities within Brainiac's ship that they must save. Zod sends Supergirl off and arrests the Legionnaires. Inside Brainiac's ship, Superman has been captured by Brainiac and his partner Lex Luthor.

Mon-El has to save Superman and tells Supergirl to get the Kryptonians to work together. Supergirl rushes to her mother's aid and sees Alura fighting with Superboy. Kara punches Connor away, but Superboy comes back to save them both from a Brainiac probe. Supergirl tells Alura of the Legion mission and challenges her to stand up to Zod. Alura pardons the Legion and sends Supergirl with them to fight Brainiac. Mon-El has entered the ship the same way as Superman and manages to save him and the city of Lanothians.
On Brainiac's ship, Brainiac has re-energized and fights Superman. During the brawl, Superman is able to get hold of the telepathic Lanthians, but Brainiac teleports away with all the other cities. The Legion manages to enter Brainiac's ship thanks to Brainiac 5's help. But even this does not seem to help and New Krypton is put back into a bottle. Superman is pummeled by Brainiac's weapons system and is declared dead.
Superman is grabbed before he hits the ground by a flying Brainiac drone, powered by Quislet. Meanwhile, on Brainiac's ship, Superboy ends up face to face with Lex Luthor.

They get free of the city and are ready to fight.
Meanwhile, Supergirl and Brainiac 5 have met. Brainy, in a brief moment alone reveals how hard it is to be near Supergirl, how much he loves her, and how hard it was when she died. It is revealed that Brainy is looking back at Supergirl's life historically. Brainy tells Kara she needs to destroy the reactor while he attempts to hold off the Phages. She smashes the satellite's power core. He tells Kara to trust her friends and she needs to trust him. He can't tell her anything about the future, but that she needs to live her own life and decide her own future. With the force-field on Brainiac's ship down, Superman is able to re-enter the ship. On board, Luthor emerges from Kandor and grabs a bottle city for himself.
Superman has gone to rescue Kandor while Zod and his soldiers fight Brainiac. In the meantime, Mon-El remains captured, but the Legion shows up to save him. Superman has found Kandor and meets up with Supergirl and Brainiac 5. He turns the city over to Supergirl, calling it her home, trusting that she will keep protect it and re-enlarge it. Brainy re-sizes the city safely. Kandor is big once more. Superman joins Zod in fighting Brainiac. Luthor has expanded the city he grabbed right inside Brainiac's ship.
Brainiac's ship has begun to plummet to New Krypton's surface. Zod is fighting with Brainiac. Superman, Supergirl, and Superboy and the rest of New Krypton work together to stop the ship. Brainiac 5 runs to help Supergirl, who is trying to hold back the expanding city. Brainy is able to stop it and re-bottles the city.

Brainiac 5 walks up and teleports away with his ancestor. Before leaving, he tells Kara to watch out for her mother. It is revealed that Luthor was working with General Lane all along. Zod is given total command over Krypton. All the guild leaders, except for Alura, were killed in the attack. Zod declares war on Earth.
War of the Supermen
With the military guild ready to attack Earth, Zod is holding Superman captive. Alura is torturing Reactron for information, only to be found by Kara. She is shocked and disgusted. She tells Alura that he father said to 'watch out for your mother', warning her about what Alura is capable of. Reactron tells Supergirl Project 7734 wanted him brought to New Krypton. Alura shoves Kara into a radiation-proof deck room and seals it, protecting Supergirl and sacrificing herself. Reactron explodes, causing a chain reaction that also destroys New Krypton. The majority of New Krypton citizens are dead and the only guild left it the military guild, since they were not on the planet when it exploded. Superman finds Supergirl; they grieve while Supergirl clutches a piece of Alura's shield. Enraged by her mother's death at the hands of Reactron, of Luthor, of Earth, Supergirl grabs the flag of Krypton, carrying the standard into battle, racing to Earth to join the war effort.
Superman manages to stop her. She breaks down; Kara feels responsible for New Krypton's destruction because she brought Reactron there. Superman assures her it wasn't her fault; they hug and are happy they still have each other. General Zod sends a bulk of his troops to the Human Defense Corps Mars base. The two sides fight, General Lane calls upon Luthor to finish his 'second project'. Using the false Rao corpse and time-pool technology,Earth has a red sun.

The Kryptonian race is now down to a mere 7,000. Meanwhile, Supergirl comes to stop Ursa. As the two fly at each other, Superman meets Zod to fight him.
Supergirl has been defeated by Ursa, but is saved last minute by the Superman family. They head to Project 7734. Before they leave, they deposit Ursa in the Phantom Zone, which has been restored. While Superman fights Zod, Superboy goes around the world putting as many Kryptonians back into the Zone as he can. Supergirl has defeated Superwoman and fights General Lane. Rather than being charged for his crimes against humanity, Lane commits suicide. With all the remaining Kryptonians in the Zone, Superman ends the war. Zod is sent back to the Zone, with Chris sealing the Zone off permanently. In the process, he is turned back into a child. He and Mon-El then explore the Zone. Supergirl mourns the loss of her people, setting up a memorial in deep space.
Batgirl and Robin
Supergirl, dressed as Linda Lang, decides to visit Stephanie Brown in Gotham, whom she has maintained a close friendship. While the two decide to go watch Dracula, a disgruntled student scientist is worried his funding will be pulled unless he comes up with some results. He activated a collider and the multiple Draculas spring from the movie. The two change into Supergirl and Batgirl, and roam Gotham destroying all the Draculas. They go back to Stephanie's home and clean up, promising to visit each other and pinky swearing to be BFF.

Unfortunately, Bizarro-Girl is the only one with this vision and she has gone missing, hiding in the Fortress, feeling scared and helpless. Supergirl comes and realizes Bizarro-Girl is not her opposite, but her reflection. Bizarro-Girl uses her solid-vision and is able to trap the Godship.
