Eve Teschmacher is a member of a shadow organization known as Leviathan and formerly the loyal henchwoman of Lex Luthor, with whom she is madly in love. She has secretly worked for Lex as a double agent posing first as the personal assistant of Cat Grant and James Olsen at CatCo Worldwide Media, and later as the research assistant of Lena Luthor, helping with her experiments on Lex's behalf. She later revealed her true alliance and betrayed Lena, giving Lex a cure for his disease, taking part in his attempt to take over the USA and went into hiding after his death, adopting the new identity of Sophie until she was captured by Lena and her mind was taken over by the artificial intelligence (A.I.) Hope.
Eve was born in North Carolina. She is implied to have had a strained relationship with her family, except for her older cousin, Bitsie, and elderly aunt, Mary. Eve took part in several beauty pageants in her early teenhood, once becoming Junior Miss North Carolina. During her high school years, she spent a summer working at a children's theme park, playing a bunny and becoming familiar with how the park's theatrical machines operated.
At the age of sixteen, both of her parents died and, since she was already in college, she found herself depressed, desperate and full of debts. That's when the mysteryous organization known as Leviathan recruit her, promising to fix all of her problems if she joined them, which they did.
Following Leviathan's orders, Eve pretended to be a huge fan of Lex and eventually developed a crush on him, writing him various letters. While he was being taken away from court after his trial, Eve waited among the crowd, calling out to him, which prompted Lex to have Otis Graves recruit her.
Eve visited Lex at Stryker's Island Penitentiary, revealing her will to help his anti-alien crusade. She subsequently began to work for Lex, becoming one of his most faithful assistants, and he sent her to infiltrate CatCo Worldwide Media to spy on Superman's friend, James Olsen.
Working for CatCo
Having sent her curriculum to CatCo, Eve was personally recommended to be her replacement as Cat's assistant by Kara Danvers herself after the latter was promoted. Cat found Eve inadequate, particularly compared to Kara, and often screamed at her. She was apparently reduced to tears on more than one occasion because of this. At one point, Eve forgot Cat's coffee, and as a punishment, Cat made her call the dean of Yale and admonish him for having given her a diploma.
Eve became James Olsen's assistant after Cat decided to take a leave of absence from CatCo. She was instantly infatuated with "Mike Matthews" (the fake identity of Mon-El) on his first day at work, and willingly helped him with his files. She and Mon-El were later caught having sexual relations in a copy room by Kara. Later on, Eve let Mon-El use her credit card to buy a suit to wear to go to Lena Luthor's charity event.
Some days later while working one night, Eve witnessed Vibe and Gypsy duel. As the two jumped into another universe, Eve questioned to herself in the background why National City was getting "weirder" every day.
After Kara rejected Mon-El, he decided to move on and went on a date with Eve, but it ended badly for her as he could only talk about Kara the whole time. Eve told Mon-El that he needed to get over his ex if he ever wanted to date anyone else, to which he quickly responded that he and Kara hadn't dated. A few days later, When Kara bumped into Eve, she asked how things were going with "Mike" as she thought they were dating. Eve told her the truth of what happened. Kara told Eve that she and "Mike" hadn't dated, to which Eve slyly replied that this was what he had said, too.
When James chose to take a little Phorian named Marcus under his care, bringing him to his office, Eve cheerfully greeted the child, bringing him and James some snacks from Noonan's. Later, she was caught in the powerful telekinetic destruction that Marcus caused in the building due to his powers' involuntary reaction with the energy released from Rhea's Transmatter portal.During the Daxamite invasion, Eve was among the CatCo employees who managed to escape when the building was attacked by the Daxamite army, thus saving herself. After CatCo reopened following the Daxamite invasion, Eve accompanied Professor Ben Lockwood to a meeting with James. The man tried to convince the media conglomerate's CEO that the invasion had deprived many people of their work and possessions and to also tell their story to the public. However, Eve interrupted their speech to inform James that CatCo's new owner, Lena Luthor, wanted him on the phone, prompting Lockwood to storm off.
Getting along with the new boss
During Lena Luthor's first day as the owner of CatCo, Eve was thrilled to meet her up-close and warmly greeted her. As she went to get Lena some coffee, Lena suggested that Eve use the private elevator as it would be faster to traverse up and down the establishment that way. Eve initially shied away from the suggestion as that particular elevator was reserved only for those at the top of CatCo’s hierarchy. However, Lena stated that starting from that day on, anyone could use the elevator at their discretion, much to Eve's delight. Later that night, Eve was seen leaving the office with Lena.
A few weeks later, Morgan Edge accused Lena of being responsible for many children in the city suffering from lead poisoning due to the lead bomb she created to counter the Daxamite invasion. When Lena returned to CatCo, she requested Eve bring her the CDC's reports on the lead poisoning, the victims' medical reports, and the statistics Edge was using. Eve agreed, also expressing to Lena her sympathies over the situation.
Shortly after, the father of a boy who lay comatose at Luthor Family Children Hospital due to lead poisoning stormed into CatCo, demanding to see Lena. Eve tried to calm him down, but Lena agreed to see him. The man accused Lena of carelessly putting his son and many other children at risk, vowing she would pay as security escorted him out.
Eve was at a staff meeting in CatCo when Morgan Edge, having survived an assassination attempt, stormed into the room blaming Lena of having tried to kill him. Afterwards, Eve brought Lena a coffee, which ended up poisoning the latter. As Kara took care of Lena, James asked Eve where she got the coffee, to which Eve indicated the cart in front of the building, right at the moment where Morgan's assassin was fleeing the scene.
When the Cult of Yuda Kal attacked CatCo to capture Tanya Spears, Eve screamed in terror as Olivia pulled a gun on James, kneeling and covering her head. James briefly checked on Eve after the group left.
Becoming Lena's assistant
After Lena brought James an overabundance of pizzas, he told Eve they would need her stomach for at least two of them. Eve joyfully agreed and asked the pair if they'll need something else, to which Lena asked a cup of coffee due to reading a "seriously dry" article. Eve promptly asked if it was the one written by Forrester from Scientific Universe Journal and recommended that Lena read Jen Steinmetz-O'Grady's work, whom she studied with at Yale. After Eve left, Lena was surprised that Eve had studied nuclear physics, to which James answered that nothing of Eve could surprise him anymore.
Later, Lena offered Eve the position of her research assistant as the former was studying the Harun-El. While working in Lena's lab, an overjoyed Eve thanked her boss for bringing her on, showing enthusiasm at the prospect of working on a project for Supergirl. Lena then explained to her what the Harun-El is and what could be its potential.
When the Kryptonian witches known as the Children of Juru attacked the D.E.O., Lena received a phone call from Alex Danvers and informed Eve of what happened, reporting that Samantha Arias wasn't getting better. Eve responded that she didn't have good news either as she was working on getting the Harun-El to heal Samantha's blood cells but instead of responding, they were getting weaker. As Lena and Eve observed a sample of Samantha's blood, Lena suddenly got an idea on how to permanently separate Samantha from Reign. After Reign and the Children of Juru were finally defeated, Lena, having secretly synthesized a portion of the Harun-El for her own experiments, called Eve to inform her that the second phase of their Harun-El trials were ready to began.Several months later when Mercy Graves broke into L-Corp building in order to destroy for good the image inducers used by National City's aliens to pass as humans, an alarmed Eve entered Lena's office to inform her that the building was lockdown. Eve received some special earplugs to resist the super-sonic sound waves Mercy was using to incapacitate everyone in L-Corp, including the security team. Realizing the woman's intentions, Kara, Lena, and Eve decided to stand against her and rushed to the server room in order to carry out the only counterattack to Mercy's plan: a manual override. The three managed to evade Mercy's men and got into one of the elevators, though Mercy mocked the women all the time through various monitors. While in the East wing on third floor at corridor B, Mercy tried to block them by remotely activating the watertight bulkheads but Kara (secretly using her Kryptonian powers) stopped them. Then, before Mercy's men could reach them, Eve closed the bulkheads by activating their hidden quick-release using her hairpin, much to her companions' surprise. Lena then sent Eve to the control room in order to take back the building's security system from Mercy, a task that Eve managed to accomplish.
Eve, alongside Lex and Otis, went to Kaznia after the Minister of Defense informed Lex of the existence of the copy of Supergirl; they eventually found the girl in a cabin in the woods after she saved a young boy from some thieves. After Lex accepted the offer of the Kaznian government to condition the copy in order to make her a weapon, Eve recognized a soldier who had made the copy "uncomfortable" so, Lex ordered for him to be executed and later scolded Eve for flinching during this. As Lex was about to came back to prison due to his seventy two free hours being nearly expired, he asked Eve how the copy's existence could be possible, to which she replied revealing him about the Harun-El and her experiments with Lena. Lex complimented Eve and ordered her to ensure she got results with her research, then explained his plan to force a war between United States and Kaznia to foil it and become a hero in the eyes of public opinion.
Further experiments with the Harun-El
Lena and Eve began testing the healing capabilities of Harun-El radiation on several samples of tumorous hearts. One day, Eve arrived late to work because of the wet leaflets spread on her car by the Children of Liberty. She apologized to Lena, who told her not to worry and that she hoped James would denounce the group's actions on Sean Chiu's TV show, "The Counterpoint Daily", which Eve proclaimed to love. Just then, one of the heart samples under glass started to collapse. They attempted to get the heart to beat again with electric shocks, but the sample died. After finding that the tumors were still growing at the time of collapse, a despondent Lena ordered Eve to perform a biopsy before destroying the sample. Eve tried to cheer up her boss by pointing out that they still had two protocols left, and since Lena was trying to cure cancer, time would definitely be needed.
Later that day, after more hearts "died", Eve and Lena noticed that instead of shrinking, the tumors keep getting bigger. Eve suggested to spend the night adjusting the protocol, but Lena told her to go home to her family for Thanksgiving. Eve protested that she didn't even wish to spend time with them, but Lena insisted they take a break from the experiments until the following day and told Eve to incinerate the heart. However, as she set the heart sample on fire, Eve discovered that the organ had become fireproof, shocking both women.
The next day, Eve was concerned over Lena's disposition. Realizing the Harun-El could potentially give humans superpowers, Lena stated that the world is on the verge of a civil war between humans and aliens and that the people they love would need their protection. Lena decided to move forward with the "Harun-El Protocol" and asked Eve to find a human subject for their next set of trials.
Sometime after this, Eve performed the "Metallo Procedure" over various subjects in her secret lab, before she finally managed to revive Otis Graves, who was previously killed in action by a Hellgrammite.
The following morning, Eve entered Lena's office, informing her that their first human subject has arrived early. She began to describe him as a "really nice guy" with bright green eyes like Lena's, but the latter cut her speech short; Lena explained that performing experiments on a human is an extremely serious task and it would be more difficult if Eve made her empathize with the subject. Eve sincerely apologized, telling Lena how much she admired the former for all the good her experiments would bring for humanity, citing her cousin, who was diagnosed with a metastasized form of cancer. Lena then asked for the subject's folder, telling Eve that they would refer to him only as "Subject 0331".
When Lex took Supergirl's copy to National City under the alias of "Linda Lee", in order to let her see how dissolute it's inhabitants lives are and she decided to stay a little longer, even approaching Lena at CatCo, Eve confronted the copy in an elevator scolding her behavior and later informed Lex that the copy "has a conscience" and it could be a problem for their project, being then instructed to infiltrate an American aircraft carrier and stage the bombardment of the house of the child that the copy saved months prior, in order to strengthen her resentment towards the Americans.
A couple of months later, when the copy had a shock while training for no apparent reason and entered a coma for some sort of disease, Lex decided to enter a radioactive chamber in order to developed an inoperable cancer, so that he could obtain Lena's assistance, Eve advised him not to do it, but to no avail and watched helplessly as he proceed poisoning himself with radiation.
Working with the D.E.O.
After Lena accepted Colonel Lauren Haley's offer to share with the government her research over the possibility to give superpowers to humans, she and Eve moved into the D.E.O. headquarter's laboratory in order to continue their experiments with the organization's resources for a couple of weeks. The move upset a lot Eve, who was very busy trying to find the gel electrophoresis apparatus when Director Alex Danvers came to visit her and Lena to ask if they needed something.
Alex told Eve where she used to keep hers when that was her laboratory before watching Lena's research deducing what she was doing and prompting the woman to ask her not to divulge the procedure with the government, since she had only agreed on giving them the finished product. Few days later, while Eve was reading the results of some new tests, she stumbled upon Alex, who entered the lab, deactivated the cameras and told both her and Lena that there was something wrong with the government and that she wanted to help their research.
Some days later, James called Eve to his office, telling her that one of his reporter had found a lead regarding a black budget used by L-Corp, knowing James and Lena had recently broke-up and supposing hat they were still in a "rough patch", Eve spoke kindly telling him that she needed to ask Lena before to comment anything regarding it, but assured him that it would probably be because of some kind of measure to prevent industrial espionage, and that they're on the part of the "good guys". Then, Eve leave, promising to ask Lena and clear the situation as soon as she can, but right after she enter the lab and tried to talk with her, Lena quickly told her it was not the right moment as she wanted to concentrate only on the project due to the pressures she received from Colonel Haley.
After the aliens' peaceful protest on National City, Colonel Haley told Lena that there could still be hope for the Country and granted her a free day telling that, for now, time was on their side. Eve cheerfully commented that "tomorrow is another day" but Lena pointed out that it could still be too late.
After Lex Luthor obtained to serve the rest of his sentence under house arrest and was transported to his mansion, while he was talking to Lena regarding the Harun-El experiment he secretly financed, Eve interrupted them entering the room in panic and was mocked by Lex who asked for a macchiato, telling her to call him "Lex" as it was easy to write; Eve ignored the latter's comment and informed Lena about James being shot and currently fighting for his life.
Later, when Lena started to work alongside Lex in order to finish the Harun-El drug and save both James and Lex's lives, Eve reached for her in the mansion's garden while she was calling Alex to check on James' condition, and told her about her concern on giving her brother full access to all their research, to which Lena replied that despite knowing what Lex was capable of, she tought his main goal at the time was simply to live. Entering back into the mansion, the two women helped Lex after he was assaulted by an utterly indifferent government agent and unhooked his handcuffs.
When Alex informed them that James was about to undergo a surgical operation with high risk of death, Eve and Lena went to National City General Hospital, meeting with her and Kara to wait until the operation is over. However, after the power outage caused by Manchester Black, Eve eavesdropped the conversation between Alex and Kelly Olsen about using the Harun-El drug on James and, having a sample of it with her propose them to let Lena use it, eventually saving him.
The next day, Lena realized that Lex was responsible of both the cut off of the backup power and James' assassination attempt, in order to gave her the incentive and the subject on which she could test the drug to guarantee its safety to be used as a healing agent, the woman replied that she would never gave him the cure and Lex, not being surprised at all, revealed that he already had someone adminisreted it to him. In that moment, the FBI agent in the room revealed to be Otis Graves disguised by an image inducer, and while he was bonding Lena to Lex's wheelchair, Eve entered, revealing her true colors to an astonished Lena and killing an FBI agent in front of her before to reveal that she had always worked for Lex. Then, after Lena was chloroformed by Otis, Eve was instructed by Lex to "take care of her", before he left the mansion.
Then, Eve brought the handcuffed Lena back into her office and sneaked away leaving behind a letter on her former boss' desk with a confession from Lex in which he stated that what he had done to her was in fact personal. Exposed as Lex's accomplice, Eve became a fugitive and risked her freedom to visit her cousin Bitsie to administer her the Harun-El cure saving her life.
Attacking the White House
The following day, she went to Washington, D.C. alongside the Red Daughter and instructed her regarding her role during that evening's operation while inspecting the sewers under the White House; after Red Daughter protested for being treated like she doesn't understand English stating that she knew it better than Eve herself, the latter smirked and commented that she looked exactly like Supergirl.Later that evening Eve, disguised by an image inducer as Chief of Staff Sarah Walker, infiltrated the White House and blackmailed senator Granberry in order to vote in favor for the official repeal of the Alien Amnesty Act. Due to a (likely voluntary) glitch in the inducer, Supergirl managed to find her position and patrolled Washington to find her, finally locating an car clocked by a device that shields the x-ray vision; after Supergirl swallowed the car's doors, Eve asked her how she had found her, to which the super-heroine answered but, as she tried to grab her, Eve turned out to be just a remotely controlled hologram and, proving she had outsmarted her, she blocked Supergirl against a wall by enclosing her in a Lexosuit alimented via Kryptonite, from which the Girl of Steel managed to free herself only after Red Daughter, posing as her, had killed all the congressmen in the Oval Office and Eve had managed to escape.
Few days later, after Otis confronted Supergirl at Stryker's Island Penitentiary and Lex detonated him to destroy all the evidence in his cell, Eve was ordered to rebuild him and resurrect him a second time, which she does gleefully informing Otis of what happened after he regain consciousness.
Fighting Supergirl and Lena in KazniaEventually Eve went back to Lex's missile base in Kaznia, where she produced more Harun-El and experimented on several abcuced aliens, inluding Kopy, until she managed to inject herself with a mixture of Harun-El drug and the aforementioned alien's DNA, obtaining self-replication powers. Then she sabotage the flight of Lena's and Kara's jet as soon as it arrived, and leave the structure only leaving some of her clones behind her. After some research, the two women found her laboratory and notes, as well as the list of aliens Lex abduced, while doing this they also found one of Eve clones into the closet and, believing it was the real one, started to threaten her that she would spend the rest of her life in prison, in order to force her to reveal where Lex was and what he had in mind. The clone was unable to answer them as the mental deterioration caused from the prolonged separation from the core body has made her only able to repeat sentences as a parrot and use monosyllabic words.
While Lena suggested Lex must have done something to Eve's mind, like some sort of brainwashing, they continue their investigation eventually discovering proof of Red Daughter's existence and Lex's plot on use her to invade America. As they were looking at some monitors with archive footage of Red Daughter, another clone of Eve appeared and recalled the first one into herself revealing her newfound powers, then knock the two women down activating the base's self-destruction (thus unlocking a briefcase containing Kryptonite). Before leaving she told them that they shouldn't be there, but they could stay as long as they wanted.
Minutes later, while Lena and Kara were trying to escape the structure, one of Eve's clones appeared in front of them in order to be followed by them and split the two women, attracting Lena on her jet and Kara (as Supergirl) in a huge warehouse. Then, as one clone engage Lena in a fight, a massive group of others attacked the Kryptonian superheroine with taser sticks, briefly bring her down to her knees.
Then, while the Kryptonian managed to defeat all of Eve's clones by whirling on herself and generating a typhoon, the other clone managed to get the upper hand on Lena stabbing her in the chest, prompting the clone to stare at her shockingly, revealing that she doesn't meant to do it and hesitating the time necessary for Lena to knock her down revealing that she was saved by Kara's recorder she was wearing under her blouse. Later, as Kara arrived on the jet, the clone disappeared revealing that the real Eve Teschmacher was never there.
Lockwood's assassination attempt
After Lex created a compact version of the Claymore satellite for his Lexosuit powering it with the energy extracted by the powers of all the aliens he has kidnapped, he experimented with it alongside Eve, ordering to a random security officer to "stand very still" and then kill him by firing to him an energy blast from his gauntlet to test his function. Due to having flinched, Eve was scolded again by Lex, however she reassured it was not because of the murder but for Otis, who was killed again by Ben Lockwood; Lex ordered Eve to kill the man and then asked her if she realized that the World was about to be theirs, prompting the girl to answer that she knew it from the very first time they met, they shared a kiss before Eve departed.
Later, a handful of Eve's clones in military suits approached Lockwood at his family's sawmill in order to assassinate him, but were taken by surprise because of his powers and defeated. The only remaining clone, in a confused state due to prolonged separation, was then questioned by the furious man.
At Lex's side in the Oval Office
When Lex settled at the Oval Office and summoned his mother and half-sister for a private tea party, Eve was at Lex's side welcoming them both and was insulted by Lena, still bitter because of her betrayal.
After Lex exposed his plans to revolutionize energy worldwide using aliens as batteries, stating that he would use the first batch of depleted aliens to charged the satellite weapon he intended to use to destroyed both Argo City and Superman, Eve asked him to speak privately and expressed her concern about wasting an amount of energy that should have lasted for decades because of his obsession on defeating Superman, however Lex reminded that they weren't partners due to him being the boss and that all victories needs fireworks.
Following Lex's toast to victory, he turned on a monitor and tried to activate the satellite but it doesn't fire, so Eve informed him of the Superfriends having attacked Shelley Island and he immediately donned his Lexosuit to take care of the matter personally. After he left the Oval Office, Eve held Lena and Lillian at gunpoint, but was taken by surprise and knocked out by her former boss, who then managed to escape.
After Lex Luthor's death, Eve went into hiding and tried to leave National City but, after arriving at the bus station, she was approached by an elderly member of Leviathan, who told her that Leviathan would have always find her. Despite her pleas, the woman informed Eve that her work on behalf of the organization was not yet finished and warned her that Leviathan was everything and everyone, and that Leviathan was coming.
A new life as Sophie
In October 2019, Eve, under a new identity as an ordinary employee named Sophie, was leaving work and was about to open her car, when someone put a bag over her head and kidnapped her.
Getting taken over by Hope
The person who kidnapped Eve turned out to be Lena Luthor, who was performing experiments to "fix humanity" at the time. When Eve begged to be let free, Lena asked her why she betrayed her, to which Eve replied that she didn't want to, explaining that "they" made her do it, referring to the Leviathan, despite she never explicitly states the organization's name to Lena. She spent some time in Lena's lab, repeatedly telling Lena that she can trust her, however Lena doesn't gave any response to her. After this, Lena let her out of her testing room and said that she and Eve would be working closely together. When Lena said that she needed to evolve Eve, the latter realized that Lena was mapping her brain to find the portions relating to honesty and loyalty. At once Eve was surrounded by the silver dots-like nanites which compose Hope, that entered her head and took over her mind. Later, Eve, controlled by Hope, was seen wearing a new white outfit while speaking to Lena.
Initially, Eve appeared to be a kind, caring, selfless and intelligent individual, who has a sense of justice, honor and good morals, considering the anti-aliens movements as "creeps" and being praised by Kara herself for her sweetness and smartness. However, she was also very sensitive and prone to crying to the point to being described as a weeper by Cat Grant. Nevertheless, Eve is an extremely hard-working woman dedicated to her job. She also has the habit to apologizing even when it's not necessary, and it's extremely rare to see her mad at someone or something.
Despite appearing as an airhead and a klutz, Eve is actually quite smart, intuitive and seemingly empathic, always proving to be supporting and full of attention for her friends and co-workers, as demonstrated when she realizes of Kara and Mon-El's feelings for one another before themselves, when she tried to comfort Lena Luthor over the time needed for their experiments and their importance for the World, or when talking with James Olsen about his break-up with Lena.
Although usually pretty mild and kind of cowardly, Eve proved to be very brave if necessary, facing with absolutely no qualm the seige of L-Corp at the hands of Mercy Graves and her terroristic group.
However, Eve's kind and timid traits are nothing more than a façade, in truth, Eve is actually a cold-blooded murderer and a traitorous sociopath who's been working as Lex Luthor's loyal double-agent for years, she considers Lex the brightest mind on Earth as well as the only one who really protect humanity from destruction and has proven to be willing to do (literally) anything for him. Eve has a twisted, dark and witty sense of humor, as demonstrated while mocking Lena after revealing her betrayal saying it was nothing personal, or while making fun of the American's lifestyle or her accent when she scolded Red Daughter.
In stark contrast with her façade, Eve is incredibly brave and nearly fearless, making no problem to infiltrate an American aircraft carrier, directly confront both Red Daughter and Supergirl herself, threaten a U.S. senator, or engaging in a fight into a facility that was about to self-destruct.
Eve is also quite scrupulous, as she meticulously reported every detail of her work (including notes) on ordered files.
However, Eve has been demonstrated not to be completely immoral or without a conscience as she might seem, being (genuinely) worried when Lex voluntarily poisoned himself with radiations, as well as getting disturbed by the sight of the execution of a Kaznia soldier she recognized as the one who had made Red Daughter "uncomfortable" or risking her freedom in order to save Bitsie's life, she also stated that she really loved both Kara and Lena, despite not as mutch as Lex; she also seemed sincerely sorry after she had to stab Lena in the chest during their fight.
Eve is madly in love with Lex, although not reciprocated.
Due to the revelation that Eve is a triple agent working for Leviathan it is unclear how much (if any) of all those personality traits are true. However she is shown to be extremely scared of Leviathan.
