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.
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.
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.
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.
Yes, there might be. In the Batman universe, Bruce Wayne is a wealthy and complex character. His love for high - end technology could potentially extend to being a fan of max cars. Fanfic writers often explore different aspects of established characters, so it's not far - fetched to imagine a story where Bruce Wayne has an interest in max cars. It could add an interesting dimension to his character, perhaps showing a more relatable side of him as he admires the engineering and design of these cars, similar to how he appreciates his own high - tech Bat - vehicles.
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.
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 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.
One great fanfic is 'The Father - Son Bond'. It beautifully explores the complex relationship between Bruce and Damian. It shows how Bruce tries to be a good father while also dealing with his role as Batman, and Damian's struggle to fit into this new world with his own strong - willed nature.
