In the fanfiction, it's possible that Bruce Wayne simply doesn't have the physical or mental capabilities to be Batman. He could be ill or injured in a way that stops him from taking on the mantle. Or maybe he's just not interested in the whole superhero thing. He could be more focused on his business or personal life, and Gotham has to find another way to deal with its crime problems.
One reason could be that Bruce Wayne never had the traumatic event that led him to become Batman in the original story. Maybe his parents' death was prevented somehow, so he never felt the need for vengeance and justice in that extreme way.
Well, in such a fanfic, it might show Bruce Wayne as a completely different entity from Batman. Maybe Bruce is just a normal rich guy who has no idea about the vigilante activities of Batman. He could be living his own life, focused on business and social events, while Batman is someone else entirely, perhaps an unknown figure with no connection to the Wayne family.
The author might introduce a new character to take on the role. Maybe a completely unknown vigilante steps up. This new character could have different motives and methods compared to Batman. For example, they could be more focused on preventing crime through community outreach rather than the intimidation tactics Batman uses.
One possible plot twist could be that Batman is actually Bruce Wayne's long - lost twin brother. They were separated at birth, and while Bruce grew up in the Wayne family, his brother had a different upbringing that led him to become Batman. This would completely change the dynamic between Bruce and Batman.
One possibility is that Thomas Wayne Batman comes from an alternate timeline. He meets Bruce Wayne in the current timeline and shows him a different way of approaching crime - fighting. Maybe he has more brutal methods, which causes Bruce to question his own more restrained approach. They could then learn from each other and create a new, more effective Batman strategy for Bruce's Gotham.
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.
One possible plot could be that Thomas Wayne somehow time - travels to the present where Bruce Wayne is Batman. Thomas could initially be shocked at how Bruce has turned out, but then come to understand his motives. He might offer some old - fashioned wisdom that helps Bruce in his fight against crime.
The dynamic could be complex. Thomas might be both proud and worried seeing Bruce as Batman. Proud that his son is carrying on the legacy, but worried about the dangers. He could be overprotective at first.
Bruce Wayne in Batman Begins fanfiction is often a complex character. He is a man on a journey of self - discovery and vengeance. In fanfiction, we might see different aspects of his training that were not fully explored in the movie. For example, his time with Ra's al Ghul could be delved into more deeply, showing his internal struggle between the teachings of the League of Shadows and his own moral code.
One comic where Thomas Wayne Batman meets Bruce Wayne is 'Batman: Rebirth'. Usually, these meetings are crafted to add depth and complexity to the Batman mythos.
One possible storyline could be exploring the immediate aftermath of Bruce's death. How does Terry McGinnis handle the loss? Another could be flashbacks to Bruce's final days, showing his last words of wisdom to Terry.
