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.
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.
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.
Another theme is his relationships. This includes his complex relationship with his father, Bruce, as well as his friendships or rivalries with other characters such as Robin (Tim Drake) or Superboy. Fanfics may focus on how these relationships evolve over time.
At first, it could be a bit rocky. Bruce is used to his own way of doing things and Buffy has her own independent streak. But they would gradually learn to respect each other. Bruce might be impressed by Buffy's combat skills and her ability to handle the supernatural. Buffy, on the other hand, could learn a lot from Bruce's strategic thinking.
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.
Well, in many such fanfictions, Damian Wayne's character might start off as the brash and over - confident Robin. He could be developed by showing his growth in teamwork. For example, he initially might resist working with the Young Justice team, seeing them as beneath his skills. But as the story progresses, he learns to value their different abilities and perspectives, thus becoming a more well - rounded and likable character.
I'm not sure if there is a specific 'Bruce Wayne lemon harem fanfic' available. There are countless fanfics out there, but a harem fanfic involving Bruce Wayne might not be as common as more traditional Batman - related fanfictions. You could try searching on specialized fanfic websites like Archive of Our Own or FanFiction.net.
A great idea for a Bruce Wayne training fanfic could be his training in stealth. He would practice moving silently through the shadows of Gotham. This could include training in different terrains, like the rooftops or the sewers.
