Well, Percy would be in disbelief. He has always been there for others, and to be betrayed would be a shock. He'd start by trying to talk to the people who betrayed him, but if that didn't work, he'd be ready for a fight. Jason would be disappointed. He believes in honor and loyalty, so this would be a big let - down for him. He'd try to find a peaceful solution, but also be prepared to stand his ground. Nico would be deeply wounded. His trust is not easily given, and once broken, he'd become very guarded. He might disappear for a while to figure out what to do next, and when he returns, he'd be a force to be reckoned with.
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 He has a more solitary nature, and the betrayal might make him even more withdrawn.
In many Percy, Nico, and Jason - related fanfictions, the idea of betrayal can vary greatly. It could be that in some stories Jason betrays Percy out of loyalty to a different group or a misunderstanding. For example, if there's a power struggle within a camp and Jason believes Percy's actions might endanger the whole camp, he might take actions that Percy perceives as betrayal. However, it could also be Nico who is betrayed by the other two if they accidentally expose his secrets that he's been keeping to protect himself and others.
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.
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.
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.
Percy might feel a deep sense of hurt. He values friendship highly, and this betrayal would make him question who he can trust. He could become more guarded and less likely to trust new people easily. Reyna would be more focused on the bigger picture. She would see the betrayal as a threat not just to herself but to the stability of the demigod world. So she would start gathering her allies, those who still believe in her, and form a strategy to counter the false accusations and the forces behind the betrayal. She would be determined to prove that she and Percy are not the traitors they are made out to be.
Perhaps Percy would try to understand the primordial's reasons for the betrayal. He's a smart and empathetic character. He might think that there was some misunderstanding or that the primordial was forced into it. So, instead of immediately retaliating, he could try to communicate with the primordial to clear things up. If that doesn't work, then he would be more likely to take a defensive stance rather than an offensive one, at least until he fully understands the situation.
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.
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.
Percy could initially be heartbroken. He's a very loyal person, and to be betrayed by those he considered family would be devastating. In Tartarus, he would have to rely on his instincts and his powers. He might also experience a lot of self - doubt, wondering if he really was as bad as they made him out to be. As time passes, he would start to plan his revenge against those who wronged him while also looking for an escape route.
The camp leaders might betray them. If there is a power struggle within the camp, and Percy and Nico are seen as threats to the current leadership's power, the leaders could set them up. They could make it look like Percy and Nico are breaking camp rules or endangering the other campers, which would lead to the rest of the camp turning against them.
