One possible plot could be that Artemis Fowl discovers the wizarding world while researching some ancient texts. He then tries to use his criminal mastermind skills to steal a powerful magical artifact from Hogwarts. Harry Potter and his friends, suspecting something is amiss, start to investigate and a battle of wits and magic ensues.
Perhaps the fairies from Artemis Fowl's world have a problem that can only be solved with the help of wizard magic. Artemis, knowing about both worlds, enlists the help of Harry Potter. Together, they have to navigate the differences between the two worlds' magic systems and deal with the political intrigue in both the wizarding world and the fairy underground.
A really interesting plot could be a time - travel scenario. Artemis Fowl accidentally gets sent back in time to the era of the founders of Hogwarts. He then has to find a way back to his own time. Harry Potter, through some magical connection, gets glimpses of Artemis's situation and has to figure out how to help him without disrupting the past too much. This could involve lots of research into ancient magic and cooperation between modern - day wizards and a brilliant non - magical human from the future.
One idea could be that Artemis Fowl discovers the wizarding world of Harry Potter while researching some ancient magical artifacts. He could then try to use his technological and strategic genius to outwit the wizards, but in the process, he forms an unlikely alliance with Harry Potter. Maybe they have to work together to stop a new dark force that is using both magic and technology to cause chaos.
Perhaps it would focus on the clash of cultures. The wizards in Harry Potter have their own set of rules and ethics, while Artemis Fowl operates in a more scientific and criminal - minded world. The story could explore how they deal with each other's differences while trying to achieve a common goal, like saving both their worlds from a mutual enemy.
Well, they might start by being suspicious of each other. Harry, coming from the wizarding world, and Artemis, a criminal mastermind in his own right. But then they could find common ground in their intelligence. Maybe they'd team up to solve a mystery that involves both the magical and non - magical worlds in the fanfiction. For example, a dark force that's stealing magical artifacts and using high - tech devices to do it.
Definitely Harry Potter and Artemis Fowl themselves. Harry is all about using magic for good and has a strong sense of justice. Artemis, on the other hand, is more self - serving at first. Their interactions would be full of clashes and growth as they learn from each other. For example, Artemis could teach Harry about strategic thinking outside of the wizarding world, while Harry could show Artemis the power of selfless magic.
Artemis Fowl and Hermione Granger would be a really interesting pairing. Hermione's vast knowledge of magic and her love for learning could clash and also complement Artemis' technological know - how and his inquisitive mind. They could have some great debates about the superiority of magic versus technology.
Perhaps Artemis, now a fairy, could use his knowledge of the human world to bridge the gap between humans and fairies in a more positive way. He could introduce human technology to the fairies, while also learning and sharing fairy magic with humans. This would create a unique story where he is sort of a cultural ambassador between the two worlds.
Well, perhaps the magical creatures from the Harry Potter universe end up in the '300' setting. Dragons could be used by the Spartans to fight their enemies. The centaurs could also join the battle, lending their archery skills. And Harry could learn some combat skills from the Spartans, which he could then use back in the wizarding world to fight Voldemort's Death Eaters.
One great crossover could be a story where Artemis Fowl uses his technological genius to help Harry Potter in the wizarding world. For example, he might create some high - tech gadgets to outwit Voldemort's Death Eaters. Another good one could involve the fairies from the Artemis Fowl universe interacting with the magical creatures in the Harry Potter world, like how they might react to a hippogriff or a centaur.
A popular one is 'The Alliance of Two Worlds'. In this story, Harry Potter and Artemis Fowl meet by chance and quickly realize that they can benefit from each other's knowledge. They form an alliance and face off against a common enemy that is trying to take over both the wizarding world and Artemis Fowl's criminal underworld. It has some really cool action scenes and great character development.
Finding a lost fanfic can be really tough. You could start by checking some of the older and larger fanfic archives.
