Return of Bruce Wayne
"Didn't you get the memo ?"

- William Earle

Fox is a research head and friend of Thomas Wayne who is demoted by Wayne Enterprises CEO William Earle to overseeing the supplies of Wayne Enterprises' aborted research projects and prototypes. Upon returning to the business, Bruce Wayne strikes up a fast friendship which allows him to all but recruit Fox as his armorer for his Batman activities. Fox proves invaluable in this role, even when he is fired by Earle. Among other things, he supplies Wayne with the materials that will eventually become the Batsuit and the Batmobile. In addition, Fox provides the cure for the Scarecrow's fear toxin.

Regarding Wayne's identity as Batman, he tells Wayne "If you don't want to tell me exactly what you're doing, when I'm asked, I don't have to lie. But don't think of me as an idiot." At the end of the film, Wayne, having gained majority control of Wayne Enterprises' shares, makes Fox the company's CEO.

Joker's terror
"Spying on 30 million people is not part of my job description."

- Lucius Fox

Fox is aware that Bruce Wayne is Batman and actively participates in a support capacity as Wayne's armorer, providing him with additional equipment such as the Batpod and a new Batsuit designed for more efficient mobility. In addition, Fox participates in his employer's vigilante activities both in the Batcave and in the field as his technical assistant and reconnaissance expert using his professional duties as cover. Fox eventually learns that Wayne has expanded on the sonar technology and developed an advanced surveillance system that can listen in and track the movement of any of the thousands of cell phones in the city; since this essentially contradicts everything Wayne believes in, Fox agrees to help but says he will resign if the machine is not destroyed after the Joker is gone. After the Joker is apprehended, Fox enters a code (his own name) as instructed by Wayne, which activates a self-destruct function for the system, and Fox presumably continues to work under Wayne.
