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.
Another plot could involve Artemis becoming a fairy and getting involved in a fairy war. His strategic mind would be put to the test as he tries to figure out ways to end the conflict. He might have to choose sides between different fairy clans, and his decision could be based on his new understanding of the fairy world and his own moral compass.
A power - hungry fairy could be the main antagonist. This fairy might see Artemis as an upstart and a threat to their own position in the fairy hierarchy. They could try to undermine Artemis at every turn, setting up traps and spreading false rumors about him in the fairy world.
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.
One possible plot could be that after a particularly dangerous mission, Artemis realizes his true feelings for Holly. He starts to show his affection in small, hesitant ways, like bringing her a special gift from one of his travels. Holly, initially surprised, gradually starts to feel the same way as they continue to work together to protect their world.
One idea could be that Artemis and Minerva are on a joint mission to recover a powerful magical artifact. During their adventure, they start to develop deeper feelings for each other. Maybe they get trapped in a dangerous place and have to rely on each other for survival, which intensifies their connection.
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.
A big plot twist could be that Artemis was actually faking his kidnapping as part of a bigger plan to infiltrate an enemy group. He lets himself be taken so he can gather intel from the inside.
One interesting plot could be exploring his dad's early adventures in the criminal underworld before Artemis was born. Maybe he was on a secret mission to retrieve a powerful magical artifact that was lost for centuries.
Another plot idea is to focus on her relationship with Artemis during a difficult time, like when he first starts getting involved in more dangerous activities. She might be trying to protect him while also respecting his growing independence. It could show the internal struggle she has as a mother.
One idea could be exploring the family's past adventures that haven't been told in the original books. Maybe there was a secret mission that Artemis's father went on when he was younger that now has consequences for the family. Another idea is to focus on the relationship between Artemis and his mother, showing how she deals with Artemis's extraordinary intelligence and his often dangerous exploits. Or perhaps a fanfic could center around a family reunion where long - lost relatives show up and bring new challenges and revelations to the Fowl family.
One possible plot could be that Artemis Fowl, as a female in this fanfic, is transported to the Naruto universe. She could use her intelligence and unique skills from her own world to help Naruto and his friends in their battles. Maybe she has some knowledge of advanced technology that could be useful against their enemies.
