What could be an interesting plot in a 'Percy, Nico and Jason are brothers' fanfiction?

Perhaps they go on a quest to find their long - lost family heritage. Along the way, they face various challenges that test their brotherly bond. They might have to cross a dangerous river that only Percy can navigate, but Jason has to use his wind powers to keep them from being swept away, while Nico uses his underworld powers to fend off the ghosts that lurk in the water.

At first, it might be rocky. Percy is more of a laid - back hero, Nico is the quiet and often misunderstood one, and Jason is the dutiful leader type. But as they spend more time together, they start to see the good in each other. Percy might teach them how to have fun and not take everything so seriously. Nico could show them the power of the underworld and its secrets. And Jason would bring a sense of discipline and strategy to their group.

One possible plot could be that they have to team up to stop an ancient evil that is rising. Each of them brings their own unique powers to the table. Percy with his control over water, Jason with his power over the wind and lightning, and Nico with his ability to manipulate the shadows. They journey to different realms to find the artifacts needed to defeat this evil.

It could be about their unique upbringing on Olympus. Maybe they have to deal with the politics among the gods while growing up. For example, Percy might struggle with Poseidon's expectations and his own identity in this divine setting. Jason could be learning about his Roman heritage in a more Greek - influenced environment. And Nico might be trying to find his place among the living and the dead while being raised on Olympus.

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.

In this fanfiction, it could be that Percy, Nico and Jason are chosen by Chaos for a special mission. Chaos might have seen something unique in them, like Percy's leadership skills, Nico's connection to the underworld and Jason's strategic mind. They join Chaos and are part of a team that has to go on a quest to find some lost artifacts that are crucial in maintaining the balance between order and chaos in the universe. Along the way, they face many challenges, make new friends and enemies, and grow as characters.

Well, they could be betrayed by someone they trusted deeply, like a fellow demigod. Maybe this person spreads false rumors about them, leading to their isolation within the demigod community. The three of them would then have to struggle to clear their names and find out who really set them up.

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 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.
