Well, for it to work in a very wrong - headed way, one might try to imagine some sort of magical portal that brings Harry Potter and his friends into Davy Jones' realm. But then, the 'lemon' part, which implies sexual content, would be completely out of place. The 'Harry Potter' characters are mainly children and young adults in a story about growing up, magic, and fighting evil. Davy Jones, on the other hand, is a menacing pirate figure. Mixing them in a sexual context is just inappropriate and would require a lot of forced and unnatural plot devices.
A 'Harry Potter x Davy Jones' lemon fanfic would be a jumbled mess. Consider the fact that 'Harry Potter' has its own set of values, like loyalty, courage, and the fight against dark magic. Davy Jones represents a more lawless, seafaring, and somewhat cursed existence. To combine them in a lemon fanfic, you'd have to distort both universes. You'd need to make up some convoluted backstory to get them in the same place, and then the sexual content would be an even greater deviation from what fans expect of either the 'Harry Potter' or 'Pirates of the Caribbean' franchises. It's just not a concept that should be pursued in fanfiction writing.
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.
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.
Finding a 'Harry Potter x Davy Jones' lemon fanfic is not something I would recommend. Firstly, lemon fanfics usually contain explicit content which is not suitable for all audiences. Secondly, such a crossover seems very odd and might not be well - developed in terms of plot and character relationships. It's better to focus on the official 'Harry Potter' stories or more mainstream fanfics that respect the original works.
There could be. However, the popularity of such a crossover might not be as widespread as more common crossovers. But if you dig deep into the fanfic communities, especially those that are open to more unique crossovers, you might strike gold. Maybe look for ones that explore how the magic in Harry's world could interact with Davy Jones' powers or his crew's nature.
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.
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.
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.
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.
It could work by having the lemon as a key ingredient in a spell that Rosmerta needs Harry's help to complete. Maybe it's a spell that can protect Hogsmeade from a new dark magic threat. Harry, with his knowledge and skills, teams up with Rosmerta, and the lemon becomes central to their mission.
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.
Fanfics about Calypso and Davy Jones are full of creative interpretations. For example, some might imagine what would happen if Calypso had been more forgiving towards Davy Jones. Their relationship was so much more than just a simple love story. It was tied to the very fabric of the sea and its magic. In fanfic, we can see different versions of how they met again after Jones' long years of servitude, and whether they could ever truly reconcile or if their differences were just too great to overcome.
