Well, in a fanfic with Bruce Wayne as president, he'd probably bring a whole new level of efficiency. He's used to running Wayne Enterprises, so he'd know how to manage a large organization like the government. He might form some sort of 'Bat - team' of experts to help him in different areas, like economic advisors, scientists, and security experts. Also, his no - nonsense attitude would mean he'd cut through a lot of the bureaucratic red tape.
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.
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.
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.
His combat skills could translate to a strong stance on national security. He'd be able to make quick and decisive military decisions. His detective skills would help him uncover political scandals and keep his administration clean. And his business acumen from running Wayne Enterprises would be useful for economic policies.
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.
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.
In a fanfic, the family aspect could also include other characters. Maybe Bruce has a new family member that Terry has to protect, or there are family secrets that they both uncover. This could lead to a lot of drama and action. It could also show how Terry's own family views his role as Batman and how that affects his relationships at home.
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.
