Percy might be angry at first. He's used to being a loyal friend, so betrayal would hit him hard. He'd probably try to find out the truth and clear his name. Jason, being a more diplomatic type, might initially be shocked and then try to reason with those who betrayed him. Nico, on the other hand, could retreat into himself. He has a more solitary nature, and the betrayal might make him even more withdrawn.
One possible reason could be jealousy among other characters. Maybe there are those who envy Percy's powers and leadership, Jason's status as a hero, or Nico's unique abilities. Another reason might be a misunderstanding. For example, they could be wrongly accused of a crime they didn't commit, which leads to others turning against them.
One of the common themes in fanfictions involving Percy, Nico, Jason and Chaos could be their epic adventures. For example, they might team up to face a new and powerful threat that emerges from the chaos itself. Maybe they have to journey through different realms, using their unique powers and personalities to overcome obstacles.
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.
Adventure is also a big theme. They are often sent on quests or missions in fanfictions. This could be to save a magical place or to retrieve a powerful artifact. These adventures allow the characters to grow and show their skills and powers. It also gives the writer a chance to create exciting new worlds and challenges for them to face.
I really like 'Percy, Nico and Jason: Bonds Beyond Camp'. In this fanfiction, it focuses on the friendship between them. It shows how they overcome their differences and work together. There are some heart - warming scenes, like when they have to protect each other from a powerful enemy. The character development is well - written.
One great 'Percy x Nico x Jason' fanfiction is 'The Three Heroes' Journey'. It beautifully weaves their characters together, exploring their friendships and the challenges they face as a trio. The author does an amazing job of capturing their individual personalities. Percy's loyalty, Nico's mystery, and Jason's leadership all shine through in the story.
Even old enemies of the demigod world, who see Percy and Jason as threats, could be the antagonists. They might use deception and betrayal as a way to weaken the demigod forces, knowing that Percy and Jason are important figures among them.
Another theme could be revenge. In some of these fanfictions, the betrayed Percy or Jason might seek to get back at those who wronged them. This could involve elaborate plans and a display of newfound power or skills. For example, Percy might use his water - controlling abilities in unexpected ways to take revenge on those who betrayed him.
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.
