There is no confirmation of him engaging in vigilante activities. >**Oliver Queen:** Photos can be doctored. They could have put Bruce Wayne's head on that body. Has Bruce Wayne left Gotham to hang out in Star City recently? No. ><sub>Arrow season 6 episode 2, "Tribute"</sub> Additionally, the future newspaper shown in the Flash mentioned a "Wayne Tech" company, which may possibly be associated with Bruce Wayne. > ><sub>Flash season one, episode one, "Pilot"</sub> **Earth-2 (Flash alternate universe)** A character by the name of "Bruce" was found on Earth-2's Barry Allen's phone alongside "Clark" and "Diana". Nothing else was said about him.
