In fanfiction, Percy's trip to the past could make him more empathetic. Meeting his ancestors or seeing historical events unfold might make him understand the struggles and joys of those in the past. This new - found empathy could change the way he interacts with people in his own time. He could also become more cautious as he sees the consequences of actions in the past and realizes how his own actions in the past (while he's there) could impact the future.
In fanfiction, if Percy is sent to Tartarus, his character development could be complex. He would likely become more self - reliant as he can't always count on his friends to save him. His view of good and evil might also change. He may realize that there are different shades of evil in Tartarus, not just the simple 'bad guys' he faced before. This could make him more empathetic in some ways, but also more cynical in others. He'd also grow in terms of his strategic thinking, as every move in Tartarus could mean life or death.

Percy's character development in this fanfiction might start with a sense of loss. Losing his demigod status means losing a big part of his identity.

Ichigo's character can develop in many ways. He might become more patient. For example, if he travels back to a time when he was more hot - headed, he'll learn from his past mistakes and become calmer. Also, his understanding of power could change. He could see how the Soul Reapers of the past used their power and learn new ways to control his own. His sense of responsibility might also grow. If he has the chance to prevent disasters from the past, he'll feel a greater obligation to protect both the Soul Society and the World of the Living.
His confidence grows. Killing Titans is no small feat, and each victory makes Percy realize his own strength and capabilities more. He becomes more self - assured in his actions and decisions.

In many fanfictions where Percy becomes the God of the Universe, his character often develops a more profound sense of responsibility. He starts to see the bigger picture of the cosmos. For example, he might become more detached from his former mortal relationships as he has to deal with the grandeur of the universe. His power also changes his perspective. He may start to view the various pantheons differently, not just as separate entities but as parts of a greater whole that he now oversees.
His character could develop in terms of his understanding of the divine world. Since he's with a goddess, he'd get a closer look at how the gods operate, their politics, and their values. This would make him more aware of his place in the grand scheme of things, not just as a demigod but as someone with a connection to a powerful goddess. He might also become more diplomatic as he tries to navigate the complex relationships within the divine realm.
