Fanfiction about Percy, Jason and Nico as Brothers: What are some interesting plot ideas?

Maybe they discover they have a long - lost relative who is in danger. So they team up, Percy using his water powers and Nico his underworld powers to fight the dark forces that are after their relative. During this, they grow closer as brothers and understand each other better.

Maybe they could have a story where they discover a secret about their family's past together. They'd have to deal with the revelations and how it affects their relationship. For example, they might find out that there was a powerful ancestor and they have to figure out how to use or protect the knowledge of this ancestor. This would involve a lot of character growth for both of them as they learn more about themselves through their family history.

A cool fanfiction idea could be that Percy, Nico, Jason are chosen by Chaos to be its champions in a battle against an ancient evil that is trying to bring total destruction. They are given special powers by Chaos and have to learn to use them quickly.

A common plotline is a quest. They are sent on a dangerous mission, like finding a lost artifact that could save the world of the gods. Along the way, they face many challenges and have to trust each other completely.

One interesting Percy, Jason and Nico fanfiction could be 'The Adventures Beyond Camp Half - Blood'. In it, they embark on a quest together that takes them to unknown realms filled with unique monsters. The author does a great job of portraying their individual personalities and how they interact with each other. Another could be 'The Bonds of Friendship', which delves deep into their relationships and how they support one another through tough times. And there's also 'The Trio's Trial' where they face a series of challenges that test their skills and loyalty to each other.

Maybe they are all transported to an alternate dimension where the rules of their world are different. Percy has to figure out how to use his powers without water, Thalia discovers new aspects of her lightning, and Nico has to deal with different types of underworld creatures. They must find a way to get back home while also helping the people in this new dimension.

There could be a story where Percy is submissive in a battle - training scenario. Nico, who has unique battle strategies, is in charge of training Percy. Percy has to follow Nico's every order, which at first he resents but then realizes the value. In a different plot, they could be in a time - travel adventure, and Percy is submissive as Nico is the only one who can navigate the time - streams. They go back to important events in their pasts and Percy has to do as Nico says to not disrupt the timeline. Also, a plot where they are in a sort of magical contract situation, and Percy is submissive to Nico until certain conditions are met, during which time they face internal and external struggles and grow closer as a result.

One idea could be Jason and Percy having to team up for a special quest that no one else can handle. Maybe they have to retrieve a powerful artifact hidden deep in a dangerous realm. They start off not getting along well because of their different leadership styles, but as the quest progresses, they learn to respect each other and combine their powers in unique ways to overcome obstacles.

One plot idea could be that Percy and Jason discover they are twins in a very unexpected way. Maybe during a quest, they start having the same strange dreams and realize they have a deeper connection. Another could be that they have to team up against a powerful enemy who is specifically targeting them because of their unique twin bond.

One great fanfiction could be about their adventure in an unknown magical realm. They might have to combine their unique powers - Jason's control over the winds, Nico's ability to summon the dead, and Percy's power over water to defeat a powerful dark force.
