The story might also focus on the relationship between Bruce and Percy. Bruce, having lost his parents, could see a bit of himself in Percy. He could become a father figure to Percy, guiding him and protecting him. Percy, on the other hand, could bring some light and a different perspective into Bruce's rather dark world. It could be a story of growth, both for Percy as he adapts to a new life with Bruce, and for Bruce as he takes on the role of a father - figure.
Bruce Wayne is very brooding and serious, while Percy Jackson is more of a laid - back and sarcastic character. Their personalities could clash in the sense that Bruce might not always understand Percy's jokes or his more carefree attitude. However, they could also complement each other. Percy's light - heartedness could break through Bruce's dark mood sometimes.
In fanfiction, they might be related through a shared enemy. Let's say there's a new super - villain who is causing chaos in both the demigod world and Gotham. Percy and Bruce start to work together to stop this foe, and during their investigations, they find out that there's a family connection between them. It could be something as simple as an ancestor who was part of a secret society that had ties to both the Greek mythology realm and the early settlers of Gotham.
In a fanfiction plot, perhaps Percy Jackson is on the run from some powerful Greek enemies and ends up in Gotham. He meets Bruce Wayne, who is intrigued by Percy's strange powers. As they spend time together, a relationship develops. Their relationship could be tested when a powerful entity from Percy's world tries to use Gotham as a base to gain power. Bruce and Percy must work together, with Percy using his demigod abilities like controlling the elements and Bruce using his Bat - gadgets and strategic mind to defeat the enemy and save Gotham and Percy's world.
Sure, fanfiction writers love to mix and match different fictional characters. In a story where Percy Jackson is dating Bruce Wayne, we might see Percy's Greek mythology - inspired powers and Bruce's high - tech gadgets and detective skills combine in interesting ways. For example, Percy could use his water - controlling abilities to help Bruce during a flood in Gotham, while Bruce could use his resources to help Percy protect Camp Half - Blood from some new threat.
Well, it could be really interesting. Harry would grow up in a very different environment. Instead of the wizarding world at first, he'd be in Gotham. Bruce Wayne, being the Dark Knight, would likely train Harry in self - defense and detective skills. Harry might bring some magic into Gotham's crime - fighting, like using spells to disarm criminals instead of batarangs. It would be a whole new take on both the Harry Potter and Batman universes.
In this fanfiction, perhaps Danny Phantom's identity gets exposed in his hometown in a way that makes it unsafe for him. Bruce Wayne, who is always on the lookout for those in need, decides to adopt Danny. Danny brings his unique perspective and powers into Bruce's world. He might start training with Bruce and the Bat - family, all while trying to keep his ghost - related problems from spilling over into Gotham's normal world.
In this fanfiction, Bruce might see a lot of himself in Harry. Harry has endured great loss at a young age, just like Bruce. So, Bruce Wayne adopts Harry Potter. Harry could then grow up with access to both the wizarding world and Batman's resources. He could use his invisibility cloak in new and creative ways to help Batman fight crime in Gotham. And perhaps he'd introduce some magical elements to the Batcave.
A possible storyline could be that Percy is on a quest and gets lost in a different dimension which happens to be Gotham. Bruce Wayne, as Batman, finds him and initially suspects him to be a threat. But as they interact, they discover some similarities in their abilities and goals. They then start to dig deeper and find out they are related through a long - lost family connection that dates back to ancient times when the gods had some influence on the early human civilizations.
They could go on a quest to find a powerful artifact that has the potential to destroy both their worlds. Bruce's detective skills and Percy's demigod powers would make them a formidable team. For example, they might have to search for an ancient Atlantean relic that has been corrupted by dark magic.
Another aspect that might be involved is the exploration of their different power sets. Percy has his demigod powers which are tied to the elements and his heritage from the Greek gods. Bruce has his physical and mental training, along with all his high - tech gadgets. In the fanfiction, they could train together, with Percy teaching Bruce some moves based on his agility from being a demigod, and Bruce showing Percy how to use some of his gadgets more effectively. There could also be a plot where an enemy is after both of them because of their unique abilities, forcing them to work together even more closely.
