Lucy Lane is the youngest daughter of Sam Lane and an unnamed woman, the estranged younger sister of Lois Lane, the aunt of Jonathan Kent and Jordan Kent, the ex-girlfriend of James Olsen, and the ex-fiancée of an unnamed man.
In the original multiverse, Lucy was a military officer in the United States Army's JAG Corps. After J'onn J'onzz's identity was exposed, Lucy was named director of the D.E.O., until the martian received a presidential pardon and was re-instated to said position.
In the new multiverse, Lucy still has a complicated relationship with her family. She got involved with Ally Allston's cult and nearly took her own life, but was saved by Lois, causing them to grow further apart.
At some point, Lucy was born in Metropolis to Sam Lane and an unnamed woman. She has an older sister, Lois, but for unspecified reasons, the two never really got along at all. Raised in a family with a long military tradition, Lucy attended the United States military academy at West Point, where she earned a Bachelor of Science degree and a commission in the United States Army as a 2nd lieutenant. Afterwards, Lucy studied at Harvard University, where she gained a JD/MBA. Lucy then went on to work for the Army's Judge Advocate General's Corps as a trial counsel (prosecutor) also serving as a legal attaché on her father's staff. In 2015, Lucy held the rank of major.
Rekindling with James
A few months after their break-up, Lucy went to National City to visit James, arriving at CatCo Worldwide Media to see him. While in his office, Lucy met Kara Danvers. After Kara left, Lucy asked James out to dinner that night to talk, as she didn't like the way they had left things in Metropolis.
James was cold to Lucy at first since she was the one to call things off between them. However, after Lucy explained her reasons, the two rekindled their relationship and even spent the week of Thanksgiving together in Ojai.
After the holidays, Lucy told James that her father, General Sam Lane, was coming to town and wanted to have dinner with them. After he agreed, Lucy left, passing by Kara on her way out and thanking her for the "invite" since, as James later explained he invited Lucy to their regular game night at Kara's apartment. She later accompanied her father as he demanded Supergirl to fight their field robot Red Tornado, causing a damage in the robot's system that activated the self emergency protocol fleeing away. That night, at dinner with General Lane, things got tense as Lucy's father thought James wasn't good enough for his daughter. Later, they're attacked by Red Tornado, but Supergirl came to rescue them. The following day, though General Lane disapproved, Lucy decides to resign from the military and stay in National City with James.
When Dirk Armstrong tried to use Cat Grant's hacked emails to force her to leave her position as CEO of CatCo, Lucy helped James, Kara, and Winn Schott to expose him and get him arrested. She was subsequently hired by Cat as CatCo Worldwide Media's general counsel.
Meanwhile, James feelings for Kara continued to grow, slowly deteriorating his relationship with Lucy. After James forgot about a date with her to help Supergirl against the evil alien supercomputer Indigo, Lucy took offense as she felt James was sidelining her in favor of Supergirl as he did before with Superman. To prove her wrong, James asked Kara's permission to tell Lucy the truth about her identity, which the latter eventually agreed to. However, Lucy breaks up with James before he can tell her anything because she found out he had talked about his father with Kara, something that he never did with her. That means he is in love with Kara, not her.
Director of the D.E.O.
Back at the army
Not long following her breakup with James, Lucy resigned from CatCo and returned to the Army. Her first billet after her return was as legal adviser to Marine Colonel Jim Harper, who was brought in to get to the bottom of the J'onn J'onzz infiltration of the D.E.O.; Lucy and Harper interrogated J'onn about how he managed to get into the agency. Like Harper, Lucy was skeptical of J'onn's claim that he actually tried to save the life of Jeremiah Danvers, who sacrificed himself in order to save the Green Martian from the real Hank Henshaw. Lucy believed J'onn to be a potential threat, his claims to have helped save the country from alien threats notwithstanding. The duo then questioned Alex Danvers on whether she knew J'onn's secret beforehand. Although Alex passed a polygraph test, Lucy still suspected she was hiding something. She ordered Alex to be arrested and hauled to Project Cadmus alongside J'onn.
Desperate to save her sister's life, Kara had James set up a meeting with Lucy at her apartment. Kara revealed that she is Supergirl - something Lucy suspected all along. Lucy expressed disbelief on why aliens like Kara and J'onn have to lie about their identities, to which Kara explained that they're willing to give up everything just to fit in on their new world. She persuades Lucy to help rescue J'onn and Alex. They intercept the truck taking J'onn and Alex to Project Cadmus; Lucy shoots out the truck's tires, allowing Alex and J'onn to escape. After Lucy and Kara return to the D.E.O., they are surprised to discover that Harper has resigned, leaving Lucy as the Director. Kara promised to help Lucy adjust to her new role while Lucy assured Kara she will eventually earn back National City's trust.
When the Flash appeared in National City, as the head of the D.E.O., Lucy helped him and Supergirl against Livewire and Silver Banshee. As she noticed James was visibly jealous to the amount of time Kara was spending with the speedster, Lucy told him that he was looking at Kara and Barry with the same eyes she looked at him and Kara with.
Lucy along with the rest of National City is later put under the control of Myriad. Under the orders of Non, she and her fellow D.E.O. agents released all of the prisoners including Maxima, the powerful queen of Almerac. As Kara arrives and tries to stop her, Lucy uses a Kryptonite bullet to slow her down, however the heroine managed to destroy the computer terminal using the afterburners from her ship to knock out Lucy and the other mind-controlled D.E.O members, preventing the prisoners from escaping.
After Kara switched off Myriad, Lucy is snapped out of the mind control and goes to visit J'onn and Superman, who was taken into the D.E.O. headquarters during his recovery. She also greets her father by embracing him, and explains the reason why Superman has not yet recovered. As General Lane orders to have J'onn J'onzz returned to a cell, Lucy tries to convince her father to release him instead, saying J'onn was wounded and that he helped save the city. However, the general replied that it does not matter. Lucy apologizes to J'onn for her father's behavior, but he responded that he has no intention to go anywhere and that her father does what he thinks is right. After Kara's victory over Non, General Lane said that the President granted J'onn a full pardon and re-instated him as the Director of the D.E.O.; then the Martian told Lucy that now they are all on the same team.
During the Anti-Monitor Crisis, Lucy as well as everyone in the multiverse except for the seven Paragons, was killed in an antimatter wave by the Anti-Monitor on December 10, 2019, only to be restored a month later, after the Paragons and the Spectre created a new universe.
In the rewritten history of Earth-Prime, Lucy's mother left her and her sister, Lois at some point in their childhood. Lois never spoke about her mother again, causing Lucy to resent and blame Lois for pushing her mother away. Sam liked to tell Lucy and Lois that he set two state records in his senior year. At some point, Lucy and Lois snuck out with Sam's rum. Later, they took a sketchy bus back to base only to find him waiting for they and he got pissed.
Becoming involved with Ally Allston
After Lucy lost her job and her fiancé, she moved in with the Kents in Metropolis, and eventually became involved with the Ally Allston's cult. Lois didn't agree with this, which made Lucy move and argue with her. Lois believed Ally was a "parasite" and responsible for the death of one of her followers, and swore to do whatever was necessary to bring Ally down. Lucy invested everything she had in Ally, so much that when Ally told her to go find her "other-self", Lucy swallowed a bottle of pills and almost drowned in the bathtub. If Lois hadn't found her and pulled her out in time, she would've died. However, they haven't talked since article Lois published about Ally came out.
Reuniting with Lois
Later, Ally arranged a meeting between Lois and Lucy at a hotel in New Carthage so that she could record Lois implying that the story was a lie. The plan went as planned and Lucy confronted Lois and recorded her admitting that she hated Ally and had left Lucy's vision out of the story.
Eventually, Sam convinced Lucy to go to the Kent Farm and make amends with Lois. They were initially hostile, but Lucy was happy to be reunited with her nephews, Jonathan and Jordan, and ended up staying all day. In the evening, she went with Lois and Sam to watch Jonathan's football game. Lucy believed that Lois had already accepted Ally's teachings, but Lois told her that Ally was still dangerous and poisoned Chrissy Beppo without her consent and they argued again until Lucy left.
The Inverse World
As Ally and some of her followers made their way to Inverse World, she told Lucy to stay behind as a "fail safe" in case her plan didn't work. Ally's plan failed and she was arrested by the DOD, so Lucy then went to the Kent Farm claiming that she had given up on ascension at the last moment and no longer believed in Ally. When Sam took her home, she drugged his tea and when he passed out she stole his access card.
Lucy is kind, caring, selfless, and intelligent. She also has a sense of justice, honor, and good morals. Lucy is one of the few humans who does not have an anti-view on aliens in general, as she knows that not all aliens are a threat to the human race. She also has a very strained relationship with her father. For currently unknown reasons, Lucy does not get along with her older sister, Lois Lane at all.Despite Lucy's good traits, she can sometimes be very arrogant to the point of being a "know-it-all", as she initially believed that superheroes like Supergirl keep their civilian identities secret to protect themselves. Kara Danvers and James Olsen later corrected her on the reason why superheroes keep their civilian identities a secret: it isn't to protect themselves, but to protect the individuals that they care about from their enemies.
In the new multiverse, Lucy has an extremely negative relationship with her older sister, Lois; due to the latter publishing an article in a failed attempt to take down Ally Allston and the Inverse Society. Prior to this, Lucy at least tried to get along with her sister and attempted to bond with her sister's family. According to Lois, Lucy was adored by her nephews, Jordan and Jonathan.As this said article was indirectly responsible for ruining Lucy's life, she severely despises Lois. She not only blames her sister for their mother abandoning them as children, but she will also not hesitate to ruin or destroy Lois' career if she ever interferes in her personal life or makes any attempt to take down Ally.
