When Percy becomes the god of heroes in fanfiction, his character undergoes a significant transformation. He becomes more of a strategist. He has to think about how to develop heroes, how to allocate powers and resources among them. His sense of humor might still be there, but it would be more subdued. He is now in a position of great authority, so he has to act accordingly. His loyalty would expand from just his friends to all heroes. He would see the potential in every hero and strive to bring it out, which is a big change from his more self - focused days as a demigod.
Percy's character would likely become more distant in some ways. While he still has his core values, being a god of heroes means he has to deal with so many more things. He might not be as approachable as before. But at the same time, he would be more powerful and confident. He would know his place in the grand scheme of things and use his power to uphold justice for heroes.
He might become more solemn. As a god, he has more responsibilities. So, he can't be as carefree as he was as a demigod. He would need to think about the big picture all the time.
His character would become more detached. Percy is usually very involved and emotional in his relationships, but as Death, he would need to be more aloof. He can't be too attached to the living as his new role demands a certain level of impartiality towards life and death.
His character might become more aloof. As a primordial god, he would be far removed from the normal world of demigods. He'd likely have a different perspective on things like friendship and loyalty. For example, he might not be as quick to jump into a fight for his friends as he used to be, because his new status would bring a different set of responsibilities.
He might become more authoritative. As the Titan King, Percy would have to command respect and make tough decisions. He can't be as carefree as he was before.
If Percy Jackson becomes a god in a crossover fanfiction, his character would experience a significant transformation. He has always been a hero who fought for the underdog. But as a god, he might have to make difficult decisions that could go against his old principles. His view of right and wrong could become more nuanced. He would also have to deal with the envy and fear of those around him. His mortality - which was a big part of his identity - would be gone, and he'd have to redefine himself in the context of immortality. His sense of time would change, and he might start seeing things from a much longer - term perspective. All these changes would make his character much more complex and different from the Percy we knew as a demigod.
Naruto's character would change in several ways. Firstly, he would become more strategic. As a lord, he has to plan for the long - term development of his land, which requires thinking ahead. His impulsiveness would be curbed as he has to deal with the complex web of politics. He would also grow in terms of wisdom. He would learn from his experiences and the advice of his advisors. His charisma would be used in a different way. Instead of just inspiring his ninja comrades, he would need to inspire all his people. His sense of justice would expand from individual cases to the overall fairness of his domain, and he would strive to make his territory a model of a just society.
He becomes more serious. Gone is the Naruto who is always cracking jokes.
His social circle would expand. He'd meet new people in the music industry, from producers to fellow singers. His daily routine would shift from demigod training to rehearsals and recording sessions.
His personality might become more reserved. As a Cullen, he'd have to fit into their more subdued lifestyle. He might lose some of his brashness.
In this fanfiction scenario, Percy's character change would be quite drastic. He would probably start to embrace the more chaotic and power - centric nature of the Titans. His relationships would be in turmoil. For example, his relationship with Annabeth would be severely tested. He might not value the same things he once did, like friendship and the protection of the camp. His new Titan - influenced self could be more self - serving, seeking to gain as much power as possible and not caring about the consequences for those around him. His values would be realigned with the Titans' more cut - throat approach to power and survival.
If Percy becomes influenced by Kronos in this fanfiction, his sense of morality would be greatly affected. He would probably lose his sense of right and wrong which was a big part of his character before. His loyalty towards Camp Half - Blood and his friends would be in jeopardy. He might start to think that the ends justify the means, which is a very Kronos - like way of thinking. And he could become more aggressive and less patient, as Kronos was always in a hurry to regain his power and rule over the world.
