He could also lose his fighting spirit. Percy is known for his courage in battles. But without hope, he may not see the point in fighting monsters or standing up against the Titans or other threats. He might even consider giving up his powers or something drastic like that.
One consequence could be that he might isolate himself from his friends. In fanfiction, Percy is often depicted as a social and heroic figure. Losing hope could make him feel like he's a burden to others and cause him to withdraw. For example, he might stop showing up at Camp Half - Blood activities.
Another result could be that it affects his relationship with the gods. Percy has always had a somewhat tenuous relationship with the Olympian gods. Losing hope might make him more cynical towards them, leading to him ignoring their requests or even turning against them, which would cause chaos in the world of the fanfiction as the balance between the mortal and divine worlds depends on his cooperation to some extent.
It's possible that his powers could even be enhanced in some ways. Losing an eye could make him more in tune with his other senses, and this could translate to his powers. For instance, his ability to sense danger through water vibrations could become sharper as he has to rely more on it. His powers might also develop in new directions. Maybe he could start to use water to create illusions to compensate for his lost vision in battle, like using water to project false images of himself to confuse his enemies.
In some fanfictions, when Naruto loses control of Kyuubi, other villages might see it as an opportunity to attack Konoha. They may think that with Naruto out of control, Konoha is in a weakened state. This could start a whole new arc of conflict where Konoha has to defend itself not only from Naruto's unleashed power but also from external threats.
Well, for fans, it limits their creative outlet. They can't freely explore and expand on the Percy Jackson universe in their own writing as they might like. For the fanfiction community, it means one less popular franchise to create stories around.
Well, for starters, it means that we might be missing out on some really great stories. Since Percy Jackson has a lot of depth to his character and the world he inhabits, if it's underestimated in fanfiction, we don't get to see all the different interpretations and creative takes that could be done. It can also lead to a sort of self - fulfilling prophecy in the fanfiction community. If new writers see that Percy Jackson is often underestimated, they may be less likely to take on the challenge of writing good fanfiction for it, which in turn keeps the overall quality down. And finally, it can make the Percy Jackson fanfiction seem less appealing to a wider audience compared to fanfiction for other series that are more highly regarded in that regard.
One consequence could be that the fanfiction community might feel less connected to the character. If Percy doesn't seem to interact with or acknowledge the fan - created stories, fans might feel like their creativity isn't being recognized. For example, they might be less motivated to write more stories about him.
For the demigods, things could change a lot too. Percy is a champion of the demigods, and his victory over Zeus might mean better treatment for demigods. They could be more respected and have more rights in the world of gods and mortals. However, it could also make them targets of those who are against Percy's actions.
One consequence is that it can damage the reputation of the 'Percy Jackson' brand. It may also lead to negative reactions from the author, publishers, and the general fan community. Additionally, it might violate certain terms of use or ethical guidelines in the fan - created content space.
On the positive side, the power he absorbs might help him save the world more effectively. He could be able to defeat stronger enemies and protect his loved ones better. However, he would also have to learn to control this power, which could be a long and difficult process. If he fails to do so, he might accidentally cause harm to those around him.
He might face immediate retaliation from Chaos's forces. They could be extremely powerful and Percy would have to fight for his life.
One consequence could be that Percy becomes more rebellious. He might not follow the gods' orders as readily as before, which could lead to all kinds of chaos in the world of the story.
