Luke was born in Gotham City to Lucius Fox. At some point, he was hired to work for Wayne Security and subsequently, for Wayne Enterprises. At some point, Luke learned of Bruce Wayne's secret identity as Batman. Bruce once fired Luke, but eventually reinstated him.
During Luke's high school graduation, his father Lucius went out to buy some ice for Luke's graduation party, only to be killed apparently by Reggie Harris. Luke was approached by police officers to identify his father's body.
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. 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.
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. 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.

However, after Kate met Parker Torres, a young cyberterrorist who was a rejected lesbian, Luke supported Kate's decision to have Batwoman come out as a lesbian to the public as her alter-ego would make a lot of individuals happy.
