Major Lucy Lane is a military officer in the United States Army's JAG Corps. She is the youngest daughter of Sam Lane, the estranged younger sister of Lois Lane, and the aunt of Jonathan Kent. Lucy is also the ex-girlfriend of James Olsen. 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.
Lucy Lane was born in Metropolis to General Sam Lane. She has an older sister, Lois, but for unspecified reasons, the two never really got along. 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.
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.
Lucy is kind, caring, selfless, and intelligent, has a sense of justice, honor and good morals, she is one of the few humans who does not have an anti-view on aliens in general, as Lucy knows that not all aliens are a threat to the human race. Lucy has a very strained relationship with her father, Sam Lane; due to his immoral traits; as Sam has a black and white view/anti-view on aliens in general. For currently unknown reasons, Lucy does not get along at all with her older sister, Lois Lane.
Despite her good traits, Lucy 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, only to be put in her place by both Kara Danvers and James Olsen, correcting her on the reason why superheroes keep their civilian identities a secret; it isn't to protect themselves but to protect the people they care about from their enemies.
- High-level intellect/Master lawyer/Expert tactician/Leader: Lucy displayed a sharp intellect and is a very respected lawyer in the JAG Corps, able to use the legal system to her advantage both inside and outside the court. As a military major, Lucy is also an expert tactician and, as stated by J'onn J'onzz himself, an extremely capable leader, able to direct the D.E.O. with efficiency.
- Expert hand-to-hand combatant: As a highly trained military officer, Lucy is an expert in unarmed combat.
- D.E.O.'s tactical suit: After she was named deputy director of the D.E.O., Lucy began to wear a special protective suit made in an unknown black material with some stealth capabilities.
- Unlike her DC comic counterpart; the Arrowverse's version of Lucy and her sister Lois do not get along at all.
- Lucy is never seen or mentioned again after Season 1 when the show moved to another channel/filming location, and the character was largely forgotten and written out.
