Premise
Bruce Wayne was orphaned at age 12 when a mugger shot his billionaire parents in an alley. Bruce was raised by his butler Alfred Pennyworth. Fifteen years later, Bruce Wayne returns after five years abroad in different countries training under different people, while his city of Gotham City welcomes him back. Alfred has eagerly waited his return, as has Bruce's best friend, Tommy Elliot, and Jim Gordon, the detective who tried and failed to find Bruce's parents' killer. Bruce also reunites with Jim's daughter, Barbara Gordon, who is now fifteen. However, when Bruce takes over his parents' company, Wayne Enterprises, Bruce discovers how much corruption there is in the city and sets out to end it by becoming the Batman, a vigilante to seek justice from those who have escaped the law.
