Bruce Wayne is super rich in comics. His wealth is vast and comes from multiple successful businesses and inheritances. This enables him to have all the resources needed for his crime-fighting and to support Gotham City in various ways.
Bruce Wayne's wealth in the comics is astronomical. He has multiple business holdings, vast real estate, and endless financial resources to fund his crime-fighting endeavors and various projects.
He might develop a greater sense of humility. Without the Batman persona to fall back on, he has to face his own limitations as a person. For example, he may struggle to get people to listen to his ideas for change when he doesn't have the intimidation factor of Batman.
Bruce Wayne's age varies depending on the comic storyline and continuity. Sometimes he's depicted as in his late 20s or early 30s, but it can change based on the specific story.
Often, she is depicted as being just as intelligent as the male Bruce Wayne. For example, she has a sharp mind for detective work and strategy. She might be able to quickly analyze crime scenes and figure out the motives of the villains.
Believable young Bruce Wayne is about showing his evolution. Start with his basic characteristics. He's smart, already showing signs of being a prodigy. But then add in the emotional aspects. He's angry about what happened to his parents but channels that anger into something positive. He might start small, like helping a neighbor who has been robbed. His relationships with other kids his age are also important. He might not fit in completely because of his different mindset. And his growing obsession with bats could be a unique quirk that you play up, as it ties into his future identity as Batman.
