In this fanfic, it could be that Bruce Wayne is presented as opposed to Batman. He might see Batman as a threat to the city's stability or his own reputation. So, instead of being Batman himself, he could be trying to find out who Batman is in order to stop him. This would be a really interesting twist on the traditional Batman story.
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 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.
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.
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.
In some fanfictions, Bruce Wayne becomes Batman after witnessing the brutal murder of his parents. This tragic event plants the seed of vengeance and justice in him. He then spends years traveling the world, learning various combat skills and detective techniques from different masters. He returns to Gotham with a newfound determination to clean up the crime - ridden city.
In this fanfiction scenario, Poison Ivy may initially be angry. She might feel betrayed if she had some sort of relationship with either Bruce Wayne or Batman before. She could also be a bit jealous, thinking that Batman has been hiding this huge part of himself from her. However, on the other hand, she could also be impressed by the lengths Bruce goes to protect the city. This new knowledge could lead to a whole new dynamic between her and Batman, with her either becoming an ally or an even more dangerous foe, depending on her motives and the events that unfold in the fanfiction.
Bruce Wayne was around 25 years old in the first Batman comic.
Bruce Wayne's death in Batman Beyond was a natural consequence of his life's journey. He had been Batman for a very long time, facing all kinds of challenges. His body had been through numerous injuries and his mind had been burdened with the weight of protecting Gotham. Over time, these factors combined with the natural aging process. His heart, which had pumped blood through his battle - worn body for so many years, finally stopped, and he passed away, but his spirit lived on in the new Batman, Terry McGinnis.
Often, she finds out. But the circumstances and how she reacts can vary depending on the specific comic arc. Sometimes it leads to complex relationships and plot developments.
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.
