[British and American] Bat Cub, but Bruce Wayne

[You come from a post-apocalyptic earth. In this dark universe, heroes are dead and magic does not exist. After discovering the sins committed by your parents, you abandoned the title of Batman and ruled the world in the name of Omega. Then you traveled through time. When something claiming to be the "Bat Cub Raising System" appears in your mind out of thin air and transports you, who has shrunk to a teenager, into a parallel universe, you almost think you are hallucinating. You heard it say: "Host, you actually have black hair and blue eyes! Then half of our goal has been accomplished!" You:… What the hell? The system, which does not know your identity at all, said in a loud voice: "No one wants to be a bat cub! Under my guidance, you will be the most successful bat cub in the future!" You:… When you were Batman, you weren't that popular. Later, you punched Arkham and kicked the League of Assassins with one operation, and the whole Gotham shivered under your Omega lamp. Robin cried when he saw it, Batman was silent when he saw it, and the system cried uncontrollably, allowing you to handle the city gently. You ask the system: "Have other bat cubs done similar things?" Then you really have to be in awe of the Batcubs, they are great in Gotham. Your system doesn't want to answer, so it covers your mouth and gives you a beat box. ========= The main character, the third person in the text, is an expansion of Forum Anke, and is not exactly the same plot as Anke. Free power generation, fate updates, sand sculptures but with a knife, write some when you have time. Intention: A family must be neat and tidy
