His story changes a great deal. He can't rely on his powers to solve problems. For instance, in battles, he'd have to use normal weapons or his intellect. His relationship with Annabeth would also be different. They might not have the same kind of adventures together. He'd be more in danger from the mythical world since he's no longer a powerful demigod.
When Percy becomes mortal in fanfic, his story takes a new turn. Firstly, he has to adapt to a normal lifespan, which is a big change from his potentially long demigod life. His connection to the gods becomes more tenuous. He may not be able to get their help as easily. Also, his place in the demigod community at Camp Half - Blood would be altered. He might feel like an outsider, and his friends may treat him differently. He'd have to find new ways to contribute and be useful. This could lead to him exploring other aspects of his personality, like his creativity or his ability to lead in non - combat situations.
If Percy Jackson becomes mortal in fanfic, he would likely lose his demigod powers. He might struggle to adapt to a normal human life. For example, he would no longer be able to control water or have his superhuman strength. He could face challenges like getting sick more often or not being able to defeat monsters as easily. His relationships might also change. His friends from Camp Half - Blood might have to protect him instead of fighting side by side with him.
His confidence would likely soar. As a god, he'd know he has more power and capabilities. So he might be more assertive in his actions and decisions.
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.
Percy's diet would be a major change. Instead of his normal diet at Camp Half - Blood, he would have to feed on blood. This could lead to some really interesting moral dilemmas in the fanfiction. Does he feed on humans? If not, how does he get the blood he needs? Maybe he tries to find a way to survive on animal blood, like some vampires in other stories do.
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.
Well, if Percy Jackson became a Sith, his powers would take a dark turn. His water - controlling abilities could be twisted into something more menacing, like using it to drown enemies in a cruel way. His loyalty to his friends might be tested as the Sith way is all about power and self - gain. He'd probably start wearing dark robes and have a red - bladed lightsaber.
The story could change in many ways. For example, Harry might start using some of the tactics that Percy uses in battles. He could also be more interested in the outdoors, like Percy, instead of just the castle grounds. And his view of magic could expand to include the more physical and elemental powers that the demigods have.
There's also 'Mortal Bonds'. This fanfic focuses on how Percy's mortal friends are affected by the knowledge of the demigod world. They have to grapple with the fact that their friend is part of a dangerous and magical world. It's interesting to see how they grow and change as they learn more, and how their relationships with Percy are both strengthened and tested.
One common theme is the discovery of the demigod world by mortals. Mortals often find themselves in the middle of this strange and dangerous world they didn't know existed before.
