Biography

Original multiverse

Early life

Luke as a baby.

Luke Fox was born in Gotham City to Lucius Fox and his unnamed wife. Growing up, he was very close to his father's goddaughter, Julia Pennyworth,[1] and held a deep admiration for his father, trying his best to make Lucius proud of him.[2][3]

In 2015, Luke graduated high school and was to attend the Massachusetts Institute of Technology.[3] His family held a party to celebrate Luke's graduation and Lucius went out to buy some ice from Sip&Dash. Luke and everyone else were waiting for him to cut the cake. However, Lucius never came back as he was murdered at the store, although his alleged killer, Reggie Harris, was immediately arrested by Crows Security.[4] Luke was approached by police officers that same night in order to identify his father's body at the morgue.[3]

Out of sorrow over his father's murder, Luke chose to never attend MIT despite his admission.[3] As a way to relieve the stress from this tragedy, he also began to intensively practice boxing.[5]

At some point in his life, Luke was hired by Bruce Wayne to work for Wayne Enterprises and subsequently appointed the head of Wayne Security. Sometime later, he learned of Bruce's secret identity as Batman and started to operate as his ally. Presumably due to a violation of his trust however, Bruce once fired Luke, despite eventually reinstating him.[6]

Meeting Kate Kane

Luke detaining Kate

In 2018, Luke was inside the Wayne Enterprises building, when he was alerted to an uninvited guest in Bruce's office. He held the stranger at gunpoint and cuffed her, who introduced herself as Bruce's cousin, Kate Kane, but he refused to believe her. He asked her specific personal information on Bruce like his birthday, which is February 19. He then asks her what Bruce's middle name is, but Kate says that was a trick question, as Bruce doesn't have a middle name.

Luke handcuffed into his surveillance room.

He subsequently brought her into his surveillance room and called the police, when she broke free and cuffed Luke to a system unit, taking his keys. Kate logged into the system, asking if the password to the Wayne Enterprises system is still Alfred, and thus copying surveillance of the gang and leaving Luke's keys for him just out of his reach, leaving him to see the resemblance between the two cousins.

Luke with Kate in Batman's cave

The following day, Luke was working on a device when Kate wrist-locked him and asked for Bruce's whereabouts. Before he could do so, she noticed an out of place heirloom previously worn by her aunt, Martha, on the bookshelf. She moved it back into place, revealing a secret elevator. Riding it down, despite Luke's objections, Kate discovered Batman's cave, realizing her cousin to be the vigilante.

Luke reading an article on Batman's supposed return.

Seeing newspaper clippings regarding the accident in which she lost her mother and sister, Luke explained Bruce had thought he'd had the calculations perfect, only to make one slight miscalculation. Luke reveals that Bruce never stopped looking for Beth's body which was never found. Having Luke re-purpose Bruce's old Batman suit, Kate took it to ambush Alice's gang. Later, Luke was reading a headline of Batman's apparent return as he smiled, thinking of the returning hope in Gotham.[6]

Working with Batwoman

After Kate started going out every night wearing the Batsuit, after one of said patrols Luke confronted her saying that she couldn't continue pretending to be Batman, prompting her to answer that she only wanted to find her sister.

Luke explain to Kate how Batman's weapons works.

Later, as Kate brought him Alice's butterfly knife to analyze it, Luke informed her that while Wayne Enterprises does have a device that can analyze DNA against another sample, he was hired to simply watch over the building and keep the lights on. However, he talk to her about Batman's suit, pointing out how the city wanted a hero that wasn't really there. He then showed her several gadgets that Batman had at his disposal, warning her that they're all very dangerous tools and that quite honestly, he doesn't know how half of them work because they were all meant for Batman. Kate taunted Luke by saying that he sounded eerily similar to his father, except Lucius was at least useful.

Luke accidentally activates the Batcomputer.

Later, after Kate took the equipment and ventured through the city to have a meeting with Alice at Burnside Park, Luke tried to stop it but end up turning on the Batcomputer instead, thus calling her via com link when she drive to the Loeb Bridge when the truck who was transporting Alice to Arkham was bombed, in a last attempt to stop her from doing it as it would be too risky.

Then, after she saved Alice but an underwater explosion caused by the GCPD and the Crows sent Kate unconscious on the shore, Luke called her several times and, as the police officers approached her, remotely activated the defibrillator built into the suit, allowing her to escape.

Kate thanks Luke for having saved her.

The following morning, Kate thanked Luke for saving her but as he looked to be tearing up, she told him that they shouldn't get so emotional, and they drop it. Then, Kate revealed how she knew it wasn't Alice and her gang that took the knife but someone else out there who doesn't want her to make that DNA test.[2]

Luke and Kate at Wayne R&D.

Few days later, Luke called Kate and told her that something of value has been stolen from Wayne Enterprises Research & Development and, once they visited it, he informed her that the security cameras were jammed, but he thought it could have been Alice's gang.

Luke shows to Kate how the rail gun works.

Later at the Batcave, Luke explained to Kate how the Batsuit was bulletproof and that the thieves took a prototype rail gun from Wayne R&D, the most lethal weapon that Bruce ever built and, using a mere prototype, he shown him that it was the only gun strong enough to penetrate the Batsuit. Bruce had it built in case the suit ever fell into the wrong hands, thus, whoever is in possession of the gun, has the only weapon that could kill Batman. However, the disruptor in the gauntlet Kate has, could neutralize it.

Kate shows Luke her invitation at Tommy Elliot party.

When trying to pinpoint who could have taken it, Luke suggested Alice, despite Kate suspecting Tommy Elliot might be behind it instead, showing him the invitation and noting that it was for Bruce rather than her. Kate figured out Tommy knew Bruce was Batman and that's why he stole the gun. Luke suggested that she put the Batsuit back on to show Tommy that Batman wasn't afraid of him to which Kate warn him that if she doesn't, then she would let down the entire city.

Luke finally admits that he didn't really believes Batman will come back.

After Tommy bombed the elevators of Elliot Tower, Kate went back to the Batcave and told him it was all her fault for having given the city hope for a hero who wasn't there, asking Luke if he really thought Bruce was coming back. Luke admitted that he doesn't and Kate replied that she might be better than Batman because she was there. Luke fixed the suit by painting the bat symbol red for Kate's Batwoman suit.

Later, while Kate faced Tommy, Luke informed her that she needed to wait 30 seconds for the neutralizer in her glove to be charged, which she managed to do.[7]

After Luke check a list of ink purchasers while Kate stated that Sophie believe she was Batwoman and wondered how Bruce made living a double-life so easily, prompting Luke to reply she didn't as the playboy thing was just a façade. Eventually, Luke's search came up with a PO Box for one of the buyers at the old Gotham Hotel. Batwoman went there finding Magpie's jewelry, computer, and 3D printer. Luke noted that Batwoman's body temperature mustn't rise the room's temperature or it would set off a bomb, also he managed to discovered that she had difficulties launching the Batarang because they were calibrated for Bruce, but he has since been recalibrated them to match her.

Luke returns the necklace to its case.

Later, after Batwoman managed to get away retrieving Martha Wayne's necklace, Luke placed it back in Bruce's office. Then he found schematics on Magpie's computer and started to print it since he couldn't decrypt them and discovered that it was a bomb necklace that Magpie swapped with the original one at the museum to take advantage of the moment in order to steal some more jewelry, allowing Batwoman to thwart it.

Whereas, Kate felt a lot of pressure on her because of it, Luke told her that it was a good news for her since Commissioner Forbes must have trust her since it seemed like the Gotham City Police Department has her on speed dial. He also confessed her that the victim was the one who put in jail the guy that killed his dad in armed robbery the night of his graduation. He also showed to Kate some footages of the primary suspect, Chris "The Fist" Medlock who got 30 years at Blackgate Penitentiary rather than execution, waived in court to kill Stanton and, due to overcrowding, was paroled a few weeks earlier.

Kate and Luke discuss the implications of Calverick, Stanton and Donnelly being corrupt.

Luke assisted Kate when, after defeating an apartment thief, she had a panic attack due to her trauma with Cartwright's death and was almost caught by the GCPD, thus deciding to take a hiatus from being Batwoman.

Luke is boxing in the Batcave.

One week later, Kate returned to the Batcave, finding Luke training with a sandbag, he told her that the reason behind the Detonator's return was likely Batwoman's absence since "when the bat’s away, the crazies will play". Luke brought Kate a bunch of files with possible suspects since Bruce was obsessed with catching The Detonator before the trail went cold seven years earlier and, looking at those files Kate began suspecting a private black ops contractor named George Adler, Sr. and visited his son discovering he was dead in 2013.

Luke informs Kate of the Detonator's new victim.

Right after discovering that and checking George Jr.'s alibi to be sure he didn’t pick up where his old man left off, Luke informed Kate through her comms that the Detonator had another victim since GCPD and Crows were clearing buildings close to Bennett Ave. which is where Mary clinic was located, prompting Kate to went there to ensure her step-sister was alright.

Luke told them about the real Detonator dying in 2013, and a rookie cop named Miguel Robles investigate on the case, however Sophie identified Robles as the Head of the Crows Homicide Division, thus making him the real mastermind behind the conspiracy.

Luke confronts his father's killer.

That evening, after Batwoman caught Robles and drag him underneath the Wayne Tower, where he planted a bomb, Luke appeared in front of them holding a gun and, after activating the building's lockdown thus locking them in the room with the bomb, he asked Robles why did he killed his father, prompting the latter to confess that he was payed by Tommy Elliot to rough up Lucius Fox for a journal he wrote, but the man got enraged after he threatened his son as well causing Robles to shot him.

Kate talks Luke out of killing Robles.

Seeing Luke ready to kill his father’s murderer, Kate confessed of having killed Cartwright, telling him that the world was short on heroes, so he should not let his anger turn him into someone he was not, convincing him to spare Robles life and, after detonating the bomb in safety, handing him over to the authorities.

Kate tells Luke and Mary to work together as they both know her secret now.

The following morning Luke thanked Kate for talking him off the ledge and confronted her about what happened with Cartwright explaining that the same thing happened between Bruce and the Joker, stating that she was a true hero to his eyes. Right at that moment, Mary entered the room and Luke was informed that now she knew the truth, prompting Luke to stubbornly keep denying that Batwoman and Kate are one and the same; thus Kate left, telling Mary and Luke to resolve it themselves.[5]

Looking for his father's journal

Luke tells Kate that Mary simply want to be part of her life.

A week later, after the Bat Team successfully thwarted the plans of a human traffic ring, Mary held a party to them at Wayne Enterprises in order to celebrate the victory with champagne, and suggested some upgrades for the Batsuit, then after Kate and Luke started to discuss their plans for permanently shutting down the criminals' operations, Mary meekly exited pointing out she wouldn't bother them as she wasn't a team member. Hearing this, Luke noted that everything she wanted was to be a part of her step-sister's life, prompting Kate to quickly dismissing it as too dangerous for her.

Luke oversees Kate and Julia's infiltration at the Lookout.

Later, after finding out that Tommy hid his father journal in a nightclub he owned named the Lookout, which was managed by notorious mobster Johnny Sabatino, Luke monitored Julia and Kate via comms while they infiltrated it, even reminding the latter to stay focused on her mission after she met her old flame, Reagan, and started to flirt with her.

Luke listen Mary as she asks him to let her go rescue Kate and Julia.

Then, after both Kate and Julia were captured, Luke informed Mary and asked her to be his tech support while he would go to the club to rescue them, however she stated that it would have been better if she was the one who would have gone there, since Sabatino's cousin, Aria, owed her a favor for saving her life and because she trusted him to back her up better than she could for him.

Luke oversees Mary's rescue mission.

Convinced, he backed her up when she successfully infiltrated the mobsters auction and caused a shortcut to give her the occasion to free Batwoman, who subsequently managed to defeat them all, retrieve the book and brought Mary to safety alongside Julia.

Luke brings Mary to the Batcave for the first time.

Afterwards, Luke brought Mary in the Batcave for the first time and prevented her from taking a picture of it stating that that place must remain a secret, despite in doing so he accidentally revealed her that Bruce Wayne is Batman, leaving her speechless. The following morning, when Kate told him that Reagan tricked her and stole her the journal, Luke was very upset, stating that because of this they were once again where they have started and Kate's life was still in danger.[19]

Luke and Kate argues.

After Kate discovered that Julia interrogated Reagan about the journal's location without informing her, she began to question her loyalty and argued with Luke, who stood in her friend's defense. When Kate told him that she couldn't trust his judgement he left the room stating that he didn't want to be around her.

Julia reveals to Luke why SRR disavowed her.

Later, Luke does some researches and discovered that Julia was disavowed by the SRR so she visited at the Crows headquarters and asked her why she wanted his father's journal, the two talked on a bench in Wilson Plaza and Julia confessed that she has taken a mission for someone outside the agency, resulting in said consequence, however she omitted the reasons for which she did it and the identity of the person to whom she accepted to work, telling that it was imperative for his safety not to know it.

Julia and Luke are kidnapped by Hush.

While they were conversing, Hush sneaked behind them both pointing his handguns at their heads and capturing them. After they were taken to Arkham, Julia was used as leverage to get Luke to comply with Alice's wishes, thus she was tortured by electrocution to inspire Luke to decode his father's journal.

Luke is forced to watch as Julia is tortured by Hush.

Seeing his friend being tortured Luke accepted to try translate his father journal and also convinced the villains to allow him some space so he could concentrate on the work, while alone with him, Julia acted as his sounding board to get him to solve the code, however after he managed to did it, Luke revealed to her that the book contained dangerous secrets they couldn't let a psychotic criminal know.

Luke tells Batwoman that his father's journal contains the secret to kill her.

When Alice and Hush returned demanding the translated journal, both Julia and Luke decided that they would not yield the code, even with their lives threatened. Right at that moment, Batwoman entered the room and offered Alice a pair of eyeglasses that could translate the journal in exchange of Luke and Julia's life, despite Luke telling the vigilante not to doing it since the journal actually contains the secret to kill her.

Julia and Luke are released from Alice's captivity and escape Arkham.

The trade was accepted, causing Julia and Luke to be released and to escape Arkham before Alice started its mass prison break.

Kate and Luke hug each other.

Later, back at Wayne Enterprises, Luke scolded Kate for what she did, stating that he wasn't worth giving Alice the secret to kill Batwoman and thus robbing Gotham of her only hope, to which Kate hugged him tight and replied that "there was no Batwoman without Luke Fox" apologizing with him for what she said in the morning and telling him how much she missed him that day.[20]

Luke hands Bruce's shard of Kryptonite to Kate.

The following day, Luke handed Kate a shard of Kryptonite that Bruce was keeping for a "friend", and was surprised after she correctly guessed the friend in question was Superman. Later he took the Kryptonite back and exited the room stating that he would find the way to destroy it.

Mary oversees Luke's attempts to destroy Kryptonite.

During the following hours Luke tried to dissolve the alien rock using sulfuric acid, hydrochloric acid and vinegar but to no avail. Then Mary, worried due to Kate being out interrogating the brother of dangerous Arkham escapee Tim "The Titan" Teslow, tried to distract herself by following Luke's attempt to destroy the mineral, eventually suggesting him to use an hammer, only to tell him to ignore her after realizing how stupid it sounded, stating she was stressed and didn't control what she said.

The Bat Team investigates the Titan.

After Kate's second confrontation with The Titan, Mary reseted her shoulder while Luke found a connection in the people that The Titan is targeting due them having all had a role into covering his medical condition, which Mary confirmed just by looking briefly at The Titan's CTs.

Mary and Luke watches the Titan's ambush at Gotham City Arena from the Batcave.

That night, after Mary managed to set a meeting between Jacob Kane and Batwoman to agree on a truce and work together and prepare an ambush for The Titan at Gotham City Arena, Luke followed the operation with Mary at the Batcave and was informed by Julia to be careful since she and Sophie didn't believe in Jacob's change of heart, a suspicious which turned out to be true since Jacob ordered his men to gun down both The Titan and Batwoman, who luckily managed to escape.

Kate tells Luke and Mary about the last shred of Kryptonite she received from Kara.

Later at Wayne Tower, Luke revealed to Kate and Mary that the Kryptonite has been turned to dust thank to the latter's "hammer" idea - actually a special press owned by Wayne Enterprises - prompting Mary to blew the dust off the table. Kate told the two of them that from now on, there wouldn't be any more secrets between them, thus revealing the two about the second shard of Kryptonite that Supergirl gave her during the Crisis, asking Luke and Mary to trust her with it until she can talk to Kara about what to do.[21]
