Well, it could be really strange and dark. Harry might grow up with a sense of the sea and the macabre. He could learn some of Davy Jones' cruel ways, but also perhaps inherit some of his power over the sea and the creatures in it.
In such a fanfiction, Harry Potter's upbringing by Davy Jones would likely change his entire personality. Instead of the kind - hearted boy we know, he might be more brooding and vengeful. Davy Jones could teach him about the dark magic of the ocean depths, and Harry might use this knowledge to protect himself in the wizarding world in ways no one expected. He may also have a strange connection with sea - based magical creatures that normal wizards don't have.
The biggest deviation would be in Harry's upbringing. Instead of the Dursleys, he has Davy Jones as a mentor. So his moral compass would be different. Also, his magical knowledge would be a blend of wizardry and the strange magic of Davy Jones.
Harry's Patronus charm could be a very interesting element when it comes to interacting with Davy Jones. Since the Patronus is a positive and powerful form of magic, it could have an effect on the dark and cursed nature of Davy Jones and his crew. Maybe it could temporarily stun them or even start to break the curse on the crew. And Davy Jones' power over the kraken could be used against the wizarding world, but wizards could use their magic to either tame the kraken or create barriers to keep it at bay.
A 'Harry Potter x Davy Jones fanfic' might be centered around a time - travel plot. Imagine if a spell in the Harry Potter world goes wrong and transports some of the characters back in time to the era when Davy Jones was at his prime. They then have to figure out how to get back to their own time while also dealing with Davy Jones' wrath. Or it could be about a student from Hogwarts who has a fascination with the sea and discovers a magical portal that leads them to Davy Jones' domain, and they must use their magic skills to survive and escape.
In the Davy Jones story, Davy Jones was a sort of malevolent spirit of the ocean. He was associated with the deep sea and the fate of sailors. Sailors believed that if they died at sea, their souls would be claimed by Davy Jones. He was a powerful and somewhat mysterious figure in nautical mythology, with his 'locker' being a place where sunken ships and the souls of drowned sailors were thought to reside.
Perhaps Davy Jones' locker has a connection to the Chamber of Secrets. In the fanfiction, Harry discovers this link and has to journey into Davy Jones' locker to find a way to defeat Voldemort. Along the way, he has to face the horrors of the locker, including Davy Jones himself and his crew of the Flying Dutchman. This could be a really dark and exciting adventure.
It really wouldn't work well. 'Harry Potter' is set in a world of wizards, witches, and magic schools, while Davy Jones is part of a pirate - based nautical world. The two have very different aesthetics and rules. A lemon fanfic would be even more out of place as it would try to force a romantic or sexual relationship between characters from these two disparate universes, which goes against the natural flow and characteristics of both 'Harry Potter' and 'Pirates of the Caribbean' worlds.
It could be amazing. Maybe Harry would grow up with a stronger sense of family heritage. He might have access to more hidden magic within the castle walls from an early age. And he could form different relationships with the portraits and ghosts in the castle compared to his original upbringing.
Well, in a 'Harry Potter raised in Potter Manor' fanfiction, we might see Harry having a different kind of upbringing. He could be surrounded by portraits of his ancestors who could offer him advice and wisdom. The manor itself might hold hidden chambers or libraries filled with rare magical knowledge. This could lead to Harry being more confident and self - assured when he finally goes to Hogwarts.
Well, it could be really interesting. Harry would probably grow up with a very different set of values. Goku is all about strength and protecting the Earth in a very physical way. Harry might learn martial arts instead of magic at first. He could be more straightforward in dealing with his enemies, using punches rather than spells. And his idea of friendship might be more like Goku's, based on mutual respect for power and a shared goal of protecting those in need.
It could be really interesting. Yugi has a kind heart and strong sense of justice from Yu - Gi - Oh. If he raised Harry Potter, he might teach Harry some unique strategies and ways of thinking. Maybe Harry would learn to play Duel Monsters instead of Quidditch at first. Also, Yugi's experience with the Millennium Puzzle could give Harry a different perspective on magic and mystery.
