The theme of social class in 'The Outsiders' can be used. In 'Percy Jackson' fanfiction, you could create different groups of demigods based on their parentage or abilities. There could be an 'outsider' group of demigods who are looked down upon, similar to how the Greasers were. Percy could then work to bridge the gap between these groups, just as he tries to unite different camps in the original series.
The idea of feeling like an outsider in 'The Outsiders' can be related to the half - bloods in 'Percy Jackson'. In fanfiction, you could have a character from 'The Outsiders' who really understands what it's like to be an outsider. They could help some of the more isolated demigods in the 'Percy Jackson' world deal with their feelings of not belonging. Maybe they could start a support group of sorts among the demigods, using their own experiences from the tough streets in 'The Outsiders' to help those who feel alone in the world of gods and monsters.
In some Percy Jackson fanfictions, Excalibur might be incorporated as a powerful weapon that finds its way into the hands of a demigod. It could be a plot device to add more power and mystery to the story.
One way is to use the Percy Jackson characters' powers in an Abrahamic setting. For example, Percy's ability to control water could be seen as a gift from God in an Abrahamic fanfiction. Another way is to have the Percy Jackson characters interact with Abrahamic figures. Like Percy meeting an angel and having a conversation about the nature of the world.
One way could be by making him a mysterious new demigod. He could have his Sharingan ability which might be related to some special power in the Percy Jackson universe, like being able to see through the Mist more clearly than others.
In a crossover fanfiction, the demon could be a result of some dark magic experiment gone wrong that combines the elements of both universes. For example, a sorcerer in the Percy Jackson world tries to use a spell from the Book of the Damned (from Supernatural) and accidentally creates a super - powerful demon. Percy and his friends, along with the Supernatural hunters, would then have to figure out how to stop it. This would involve the demigods using their unique powers like controlling water or flying, while the hunters use their knowledge of exorcisms and demon lore.
In the fanfiction, the 'ocean eyes' could be linked to a lost underwater civilization. A character with 'ocean eyes' might start having visions of this civilization through their eyes. These visions could guide them and their friends on a quest to find this lost place. Along the way, they would face various challenges and enemies, all while trying to figure out the significance of the 'ocean eyes' and the lost civilization.
They can be used as a MacGuffin. The characters could be searching for a special monofilament wire that has unique properties, like being able to cut through any material or having the power to nullify magic. This search could drive the plot forward as the characters face various challenges and enemies while trying to obtain it.
Well, one way could be that in the fanfiction, Naruto's powers are somehow related to the Shinto gods. Maybe Naruto is on a quest in the Percy Jackson universe and he encounters a Shinto god who bestows him with a new power or task. For example, a Shinto god could give Naruto the ability to control water in a more magical way, similar to how demigods in Percy Jackson have special powers related to the gods.
Another possibility is that the Sharingan is a magical artifact that has been lost in the Percy Jackson world. A group of demigods could stumble upon it during one of their quests. They might not understand what it is at first, but as they start to explore its powers, they realize its potential. However, they also face the danger of the Sharingan's negative effects, such as the overuse leading to blindness. This would add an interesting dynamic to the story as they try to balance using this powerful tool while avoiding its drawbacks.
One way is to give them limitations. In a school shooting situation, their powers might be affected by the modern environment. For instance, if there are metal detectors in the school, Percy might not be able to bring his sword in easily. So he has to rely on his other skills. Also, the characters can be involved in the pre - shooting events. Maybe they notice some strange behavior in a student who could be the potential shooter. They try to investigate in a way that normal students might, like reporting it to the school counselor, but also use their demigod intuition to dig deeper. This shows a more realistic integration of the Percy Jackson characters into the school shooting fanfiction scenario.
The concept could be integrated by having a quest centered around love potions. Maybe a powerful sorcerer has created a large quantity of love potions and is using them to gain control over various mythical creatures. Percy and his friends have to stop this sorcerer. Along the way, they learn about the properties of love potions, like how they can be counteracted with certain antidotes made from rare magical plants. Also, they might discover that some of the demigods at Camp Half - Blood have been unknowingly affected by these potions already, which adds another layer of mystery and urgency to their quest.
