Another development could be Percy joining forces with unexpected allies. These could be characters who were once his enemies or neutral parties. Together, they could form a new group with a different set of values compared to his old friends. They could work towards a common goal that is in opposition to those who betrayed Percy, while Percy also tries to figure out how to deal with his feelings of betrayal and move forward.
One way the story could develop is Percy becoming more of a lone wolf. He might isolate himself from his old friends and allies, distrusting everyone. He could then embark on a journey to discover the true motives behind the betrayal. Along the way, he could meet new characters who help him regain his trust in people and ultimately seek revenge or redemption against those who betrayed him.
At first, Percy could be in shock. He can't believe that the gods, whom he has served and trusted, would betray him. But then, as the reality sinks in, he might become determined to get justice. He starts to plan his next moves carefully, using his wits and the skills he has learned over the years. He may also feel a sense of sadness and loneliness, as he realizes he is now on his own against the powerful gods.
Well, Ares could be involved. He has had his clashes with Percy in the original stories. In fanfiction, his war - like nature and desire for chaos could make him set up Percy to look like he's betrayed the community. Also, Octavian from the Roman side might be a character in such a scenario. He's power - hungry and jealous of Percy's status. He could spread false rumors or create situations that make it seem as if Percy has betrayed the Roman demigod community.
Percy might initially be confused. He might start to question everything that led up to the betrayal. His mind could be racing, trying to figure out if there were any signs he missed. He might also be hurt, but the confusion could overshadow the pain at first as he tries to make sense of the situation.
After Percy's death, his friends might start a rebellion against the Gods. They would be angry and feel that Percy was unjustly killed. This could lead to a full - scale war between the demigods and the Gods.
He may also try to figure out what went wrong. Percy is a smart demigod, and he would likely not just accept the betrayal without trying to understand the cause. So, he might start investigating, talking to other characters who might have some insight, like the other demigods or even some minor gods who are friendly to him.
After the betrayal, Harry might become more cynical. He may start to question his previous beliefs and the people around him. His trust in others is shattered, which could lead him to be more guarded and self - reliant. He could also develop a darker side to his personality as he grapples with the pain of betrayal.
After joining Chaos, Percy's character evolves into a more complex one. He is no longer the naive hero he once was. He gains a new sense of purpose. With Chaos, he might be involved in more dangerous and morally ambiguous situations, which forces him to re - evaluate his values. He may become more independent and self - reliant, relying less on the support he used to get from his old friends and more on his own skills and the new allies he finds in Chaos.
He becomes more confident. With Hyperion's power, Percy has a new level of self - assurance. He's not as hesitant in battles or when making decisions.
Communication is key. Ash could realize his mistake and sit down with Dawn to have an honest conversation about why he acted the way he did. He can apologize sincerely and promise to never let it happen again. Dawn, being the understanding person she is, might forgive him.
In a fanfiction like this, it could be that Percy's powers or abilities were starting to make others jealous. His friends might have felt overshadowed and, in a moment of weakness, turned on him. Also, there could be an outside influence, like a dark force that was manipulating people's minds to make them betray Percy.
