It could make their relationships with Annabeth really tense. Since Percy is close to Annabeth, and if he's fighting with Jason over Nico, Annabeth might be caught in the middle. She could try to mediate but also be frustrated with Percy for getting into the fight.
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.
Well, it could be because they both care deeply about Nico in different ways. Maybe Jason sees Nico as a great friend and ally, and Percy feels the same but in a more possessive way. In fanfiction, authors often play with these complex relationships to create drama.
However, Jason has his own set of powerful abilities. His control over lightning gives him a great offensive power, and his ability to fly can give him an advantage in both battle and mobility. In some fanfictions where the setting is more favorable to his powers, he could be considered the most powerful. For example, in a high - altitude battle or in a place where there are a lot of electrical sources he can draw power from.
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.
It might be a test of strength. They could both be trying to prove themselves, either to their friends or to some higher power in the fanfiction world. They want to see who is truly the stronger hero.
One reason could be jealousy. Maybe Nico is jealous of Percy's popularity at Camp Half - Blood. Another reason might be a difference in their goals. Percy wants to protect the camp and the mortal world in a certain way, and Nico has his own ideas that don't align with Percy's. So, this divergence of interests could lead to a fight.
A Percy and Nico fight in fanfiction might be a complex affair. Their respective loyalties could come into play. Percy is loyal to Camp Half - Blood and Nico has his own complex allegiances. They could be fighting because of different ideas about how to deal with a new threat to the demigod world. Percy might think of a more upfront approach using his powers, while Nico could be more inclined towards using his knowledge of the Underworld and the dead to outwit the threat. This difference in approach could lead to a fight between them as they try to impose their methods on each other.
One great fanfiction is 'The Adventures of Nico, Percy and Jason'. It really captures their unique personalities well. The author does an amazing job of putting them in new and exciting situations that feel true to the original series.
There's also 'FanficHero'. This author is great at creating unique storylines for Percy, Nico, and Jason. In one of their fanfictions, the three are transported to a different dimension and have to find their way back while also dealing with new and strange threats. Their writing style is very engaging and keeps the readers hooked from start to finish.
