Well, a really cool plot could be that Helen of Troy is not just a regular mortal as was thought, but actually has some demigod blood in her. Percy senses this and they start to explore her past together. They find out that her demigod heritage is being targeted by an ancient evil. Percy then has to protect her while also dealing with the various gods and goddesses who have their own interests in Helen and the situation. Along the way, they encounter mythical creatures from both the Percy Jackson world and the Trojan War era.
A great plot might involve Percy's demigod abilities being the key to resolving a long - standing mystery related to Helen of Troy. For example, he discovers that there was a prophecy about Helen that was never fully understood. His ability to interact with the gods and his own unique skills would help him figure it out. Also, it could be interesting if Percy's friends from Camp Half - Blood get involved in the story too, adding their own powers and personalities to the mix.
One plot idea could be that Percy Jackson is sent on a quest that somehow intersects with the story of Helen of Troy. Maybe he has to prevent a new Trojan War from starting. Another could be that Helen of Troy has some sort of hidden power that only Percy can unlock, and they have to team up to defeat a common enemy. Or perhaps Percy gets transported back in time to the era of Helen of Troy and has to navigate the complex politics and mythology of that time.
One plot idea could be Percy Jackson somehow getting transported to the time of the Trojan War. He could use his demigod powers to influence the outcome. Maybe he teams up with Achilles, and together they face off against the gods who are meddling in the war in ways different from the original myth.
Percy Jackson and Helen of Troy would interact in a very complex way. Percy, being a demigod, has a different view of the world compared to Helen. He is used to fighting monsters and dealing with the gods on a more personal level. Helen, who has been through so much in the Trojan War, would have a sense of weariness and wisdom. Percy would probably be a bit brash in his attempts to befriend her at first. But as they spend more time together, they would learn from each other. Percy could show Helen that there are different ways to be strong, not just through beauty like she was known for. And Helen could show Percy the importance of diplomacy and the long - term consequences of actions, as seen in the Trojan War.
The plot might center around the Troy descendant trying to reclaim the glory of their ancient city. They see Percy as a key figure, perhaps believing he has the power to help them restore Troy to its former greatness. Helen, on the other hand, is caught in the middle. She has her own connection to the Troy story, and her presence causes both attraction and conflict. The fanfic could explore how they navigate through the complex relationships, power struggles, and the shadow of the past that looms over them.
One idea could be a quest where Percy and Artemis have to team up to rescue a group of demigods captured by a powerful new enemy. Maybe a Titan who has found a way to drain the powers of young demigods. Percy's skills in water manipulation and combat, combined with Artemis's archery and her connection to the moon, would make for an exciting adventure as they face various challenges along the way.
Well, a plot could involve Percy Jackson stumbling upon a hidden cave where cavemen are in a sort of stasis. When they wake up, they mistake Percy for a god because of his powers. Percy then has to teach them about the modern world while also learning about their primitive yet magical ways of life. Maybe there are ancient artifacts in the cave that are related to the Greek gods and Percy has to protect them from being misused.
One plot idea could be that Percy has to face Arachne in a battle of wits rather than just a physical fight. Maybe Arachne weaves illusions within her webs that Percy has to break through to reach her. Another could be a scenario where Arachne tries to use Percy to get revenge on the gods by tricking him into stealing an important artifact from Olympus. A third idea is that Percy and Arachne form an unlikely alliance when a greater threat emerges that endangers both of their existences.
A plot could involve Percy accidentally stumbling into Artemis' territory. At first, Artemis is angry but then realizes Percy has information about a threat to her hunters. So they start an adventure to stop this threat. During the journey, they learn more about each other's worlds and develop a mutual respect. Or maybe there's a spell that makes Artemis lose her powers temporarily and Percy has to protect her while she regains them.
A possible plot is Percy being sent on a mission by the gods to study a strange phenomenon in the ocean that is affecting both the mortal and demigod worlds. He uses his scientific skills, which he has developed over time, to analyze the situation. He might encounter sea monsters that are acting oddly due to this phenomenon and has to figure out how to stop it. Or perhaps Percy is recruited by a secret scientific organization within the demigod world that is trying to find a way to bridge the gap between the magic of the gods and modern - day mortal science. He could bring a unique perspective with his experiences as a demigod.
A really interesting plot could be that Cupid, for some reason, decides to make Percy the ultimate symbol of love in the demigod world. Percy is then thrust into a role he doesn't understand, having to deal with love - sick demigods coming to him for advice. Meanwhile, he has his own relationship problems, like his feelings for Annabeth being complicated by this new status. He has to figure out how to handle Cupid's meddling and restore some normalcy to the love lives of those around him.
One idea could be Percy having to adapt his demigod skills to his new situation in a wheelchair. For example, he might have to figure out new ways to fight monsters. Maybe he uses his wheelchair as a weapon somehow, like ramming into foes or using it to block attacks. Another plot could involve his friends helping him adjust, and together they discover new powers or artifacts that are specifically useful to him in his wheelchair - bound state.
