However, Waller noticed Batman was getting older and increasingly unable to handle the day-to-day intensities of crimefighting. She knew that one day Batman would have to retire or he'd be killed on duty. Fearing that fact and believing the world always needed Batman, she decided to create a new one. Waller, with old connections to Project Cadmus, gathered the technology necessary for her movement, codenamed "Project Batman Beyond." Bruce Wayne's DNA was obtained from a mission where he got injured—a small blood sample on a piece of gauze left at the scene of the mission. Years later in Neo Gotham, she found a couple that was psychologically identical to Bruce's parents. Warren McGinnis was called in to get a routine flu shot that actually was a nanotech solution to replace his reproductive DNA with that of Bruce Wayne's. A year later, Mary McGinnis gave birth to Terry, who was a combination of her and Bruce. Waller executed the final phase of her plan when Terry was eight years old: hiring an assassin—Andrea Beaumont, Bruce Wayne's former fiancée and the enigmatic Phantasm—to kill Terry's parents so that the trauma of seeing his parents murdered in front of him might motivate Terry to someday become a hero equivalent to Batman. However, Beaumont got cold feet at the last minute and realized that murdering in Batman's name would dishonour his legacy.

Nevertheless, eight years later, Terry's father was murdered and the young teen encountered Bruce by chance, sealing Terry's fate forever. Waller's admission of guilt and affirmation of Terry's destiny allowed him to overcome his anger and bitterness. Terry then decided to propose to his longtime girlfriend, Dana and fully accepts his role as Batman. Terry also accepted Bruce as his father. According to episode co-writer Dwayne McDuffie, Bruce, despite having no involvement with Waller's plan, and as a master detective, becomes aware that Terry and Matt are his genetic offspring at some point after Terry assumes the role of Batman, and figures out the machinations of Waller and Project Cadmus due to the fact that they are the only people with such means; however, he never brings
