In some fanfictions, if Percy Jackson becomes Death, he might gain the power to decide the fates of all beings. He could be seen as a very solemn and powerful figure, no longer the carefree demigod. His relationships with other characters would also change drastically. For example, his friends might fear him at first, but then come to understand his new role and the importance of it in the grand scheme of things.
Well, if Percy Jackson were to become an Avenger in fanfiction, there would be some interesting dynamics. For one, his loyalty to his demigod friends might conflict with the Avengers' way of doing things at times. But his ability to think on his feet, which he developed from all his quests, would help him adapt quickly. And his relationship with the other Avengers, like maybe a friendly rivalry with Thor over who has better control over elemental powers, could be a great plot point.
One change would be his interests. Instead of just focusing on Greek mythology and his demigod adventures, he now has an additional passion for dragons. He might start spending his free time reading dragon lore.
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.
Yes, there are likely some fanfictions out there with the concept of 'Percy Jackson is death'. Fanfiction writers often come up with unique and creative interpretations of existing characters. You can start by looking on popular fanfiction websites like Archive of Our Own or FanFiction.net.
Maybe Percy, as a ninja, would have to train in a special dojo hidden in the demigod world. He could learn traditional ninja skills like stealth and swordsmanship from an old master who is also a demigod. This would be an interesting combination of his Greek demigod heritage and new ninja skills, and he could use his newfound skills to protect Camp Half - Blood from new threats.
In this type of fanfiction, it's a really interesting concept. One possible scenario could be that Percy's death is a heroic sacrifice. Maybe he gives his life to save the world from an even greater threat than before. And when he becomes a god, he might use his new powers to bring about a new era of peace among the gods and demigods. His transformation could also mean changes in his relationships. For example, his friends might now have to view him in a different light, as a divine being rather than just a fellow demigod.
If Percy becomes a vampire, his relationships would change drastically. His friends from Camp Half - Blood might be afraid of him or try to find a way to 'cure' him. His relationship with Annabeth would be put to the test. She might be determined to save him, but also conflicted because of what he has become. And Percy himself would have to deal with the fact that he now belongs to a different 'species' so to speak.
If Percy Jackson were to become a hidden god in fanfiction, it would likely involve a lot of mystery and suspense. He'd have to navigate a world where he couldn't reveal his true nature easily and could potentially uncover some dark secrets along the way.
His friends from Camp Half - Blood like Annabeth could be his allies. Annabeth is smart and strategic, and she would be able to offer valuable advice as Percy goes through the process of becoming a minor god.
