What are some interesting ideas for a 'Percy Fade Away' fanfiction?

First, think about the reason for Percy's fade away. Is it something supernatural? Or is it related to a personal sacrifice? Once you have that, start with a scene that sets the mood. For example, if it's a supernatural cause, you could start with Percy noticing strange things around him like objects disappearing or his reflection fading. Then introduce the other characters' reactions to his situation.

One idea could be a fanfiction that focuses on what happened to Haku after Chihiro left the spirit world. Maybe he had to face new challenges or make difficult choices. Another could be a story about Chihiro returning to the spirit world as an adult, but finding it completely changed. And a third idea could be a fanfiction that delves into the backstories of the minor spirits we saw in the movie, like the soot sprites and how they came to be in the bathhouse.

One idea could be a fanfiction where Percy and his friends go on a new quest in a modern, urban setting. Instead of the usual mythological locations, they have to deal with monsters hiding in big cities. Another idea is a story that focuses on the relationships between the characters in a more in - depth way, like exploring the friendship between Percy and Grover during their off - quest times. And a third idea could be a time - travel fanfiction, where Percy gets sent back to the time of the ancient Greek heroes and has to interact with them while still holding onto his modern values.

One idea could be to explore Percy's life after he has fully mastered his powers. Maybe he goes on a quest to find a long - lost relative who also has demigod powers. Another could be a story where Percy and his friends have to deal with a new type of monster that is immune to their usual weapons and they have to find a creative way to defeat it.

One idea could be a crossover with 'Alice in Wonderland'. Chihiro could find herself in Wonderland and have to navigate through the strange rules and characters there, while also using her experiences from the Spirit World. Maybe she'd meet the Cheshire Cat who could be as mischievous as some of the spirits she met in Spirited Away.

One possible plot could be Percy's struggle against the power that seals him away. Maybe he has to find a way to communicate with his friends on the outside to get help. Another could be the discovery of the true motives behind his seclusion.

One plot idea could be Percy having to team up with Hera to rescue a group of demigods who have been captured by an ancient monster. Hera, despite her usual aloofness, realizes she needs Percy's unique skills.

I'm not sure of a specific 'fade away novel' off the top of my head. However, some novels that have elements of fading away could be 'The Great Gatsby'. In it, the dreams and illusions of the characters fade away as the story progresses. Another could be 'The Catcher in the Rye' where Holden's innocence and his view of the world seem to fade as he experiences more of life.

One idea could be a crossover with the Harry Potter universe. Percy could visit Hogwarts and have to deal with both magical and mythological threats. Maybe he'd team up with Harry to defeat a common enemy that combines dark magic and ancient Greek monsters.

Well, you could write a fanfiction where Percy loses his memory and has to rediscover his powers and his place among the demigods. Or perhaps a story about how the minor gods in the Percy Jackson universe form their own alliance because they feel overlooked by the Olympians. You could also create a fanfic that focuses on Annabeth's journey if she was separated from Percy and had to fend for herself in a dangerous situation.
