Obviously, Bruce Wayne's son is a central character. Alfred Pennyworth often makes an appearance as he is an important figure in the Wayne family. Dick Grayson might also be popular as he can act as a mentor or a brother - like figure to Bruce Wayne's son. And of course, the villains from the Batman universe like the Joker or Ra's al Ghul can also be included to create conflict.
Tim Drake is another popular character. His intelligence and detective skills are on par with Bruce's, and his story of becoming Robin and his relationship with Bruce and the other siblings offer a lot of potential for fanfic writers. His insecurities and determination make him a relatable and interesting character in the 'Bruce Wayne and his kids' fanfic universe.
A great Bruce Wayne sons fanfic could involve the son traveling to another dimension. In this new world, he has to find his way back home while also dealing with the differences in how things work there. He might meet alternate versions of his family and friends. This would be a chance to explore his character in a whole new setting. It could also show how his upbringing in the Wayne family has equipped him to handle such strange and difficult situations.
Well, in many Bruce Wayne daughter fanfics, an original character that is quite popular is her mentor. This could be someone outside of the Bat - family who teaches her different skills or a different way of thinking. It gives the daughter a chance to grow independently. And then there's the love interest. An original character designed to be her romantic partner, who may have their own secrets and powers, adding more drama to the story.
Another reason is the contrast between them. Bruce is a regular human with extraordinary skills and resources, while Clark is an alien with super - powers. Fanfic writers can explore how these differences play out in various situations, whether it's in a fight, a friendship, or a moral dilemma. For example, a fanfic might show how Bruce's cynicism and Clark's optimism clash and then eventually find common ground.
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.
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.
Another aspect could be that in some darker fanfics, if Bruce Wayne were to cross a moral line, perhaps Alfred would have to take more extreme measures. He might cut off Bruce's financial resources related to his vigilante activities. This would force Bruce to re - evaluate his actions and the way he operates as Batman. It's a way of punishing him to make him understand the importance of ethics even in his fight against crime.
There are some original characters that often pop up. One could be a young detective trainee who befriends Bruce and helps him in his early investigations. Another might be a street - smart kid who shows Bruce the ropes of the rougher parts of Gotham. And then there's often an older mentor figure, aside from Alfred, who teaches Bruce some unique combat or survival skills.
The plot is also important. It could involve them facing a new villain or a threat to Gotham that tests their relationship. Maybe a situation where Damian's actions put him at odds with Bruce's code of ethics, and they have to work through it. This kind of plot tension can make the fanfic really engaging.
Damian Wayne is often a main character. He's Bruce Wayne's son with Talia al Ghul and has been trained in combat from a young age.
