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.
Percy's character could become more mysterious. Primordial gods are often shrouded in mystery, and he would be no exception. He might start to keep secrets from his old friends, which is a big change from his open - book self before. His actions might seem more unpredictable as he is now operating on a different plane of existence.
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.
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.
Well, he might start by being a bit confused and overwhelmed. As he steps into the role of the god of fate, he gradually realizes the enormity of his new powers. He could become more serious and contemplative, thinking about the threads of fate he now controls. His relationships might also change, as he has a different standing in the world of gods and demigods.
He would likely become more assertive. As a god, he has more power and responsibility, so he can't be as laid - back as he was before. He might also develop a more primal side, influenced by the wolf nature, like being more instinctive in his decision - making.
Percy might struggle with his new identity. He has been a demigod for so long, and suddenly becoming a primordial god means he has to re - evaluate his place in the world. He may miss his old life, his friends, and the simplicity of being a demigod. Adjusting to the new powers and responsibilities is not going to be easy.
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 personality would likely experience a shift towards a more solemn and responsible demeanor. With godly powers come great responsibilities. Percy would no longer be able to act as carelessly as he did as a demigod. He might become more reserved in showing his emotions, especially as he realizes that his actions as a god can have far - reaching consequences. Also, his loyalty might be tested as he has to balance his new divine status with his relationships from his mortal days.
His life would change drastically. He would be a being of immense power. He would no longer have to fear the wrath of the Olympians as he would be on a similar or even higher level. He could shape the world as he wished.
Their relationship could transform into a more mentor - mentee dynamic. Percy, with his godly knowledge and powers, could start guiding Annabeth in a different way. Annabeth, being the intelligent and ambitious demigod she is, would learn from Percy and they could collaborate on projects that benefit both the demigod and godly worlds, like building better defenses for Camp Half - Blood or creating new alliances among the gods.
