Often, there are themes of self - discovery. Since he's now a blind god, Percy has to re - discover who he is and what he can do. There's also the theme of relationships. His relationships with other gods or mortals might change because of his new status.
The common themes include the concept of power in a different form. As a blind god, Percy's power might manifest in new and unexpected ways. Also, themes of isolation can be present. He might feel isolated because of his blindness, and the fanfiction could explore how he overcomes this. Another theme could be redemption, where Percy uses his new situation to make amends for past mistakes.
One common theme is struggle. Percy has to struggle with his new condition as a blind god. Another could be adaptation, as he tries to adapt to his changed circumstances.
Support from friends is also a major theme. His friends like Annabeth and Grover play important roles in helping him through his difficult time. They might help him get around, or boost his confidence when he's feeling down about his blindness. In some fanfictions, their friendship is deepened because of Percy's situation.
One common theme is the idea of adaptation. Since Percy is blind, the fanfictions often focus on how he adapts to his demigod life. For example, he has to learn to fight monsters without relying fully on his sight.
Friendship is also a big theme. His friends support him through his challenges. For example, Grover might use his empathy link with Percy in a new way to help him out. It shows how their bonds are strengthened in difficult times.
One common theme is the struggle of the Blind Hunter. It could be about how they overcome their disability in a world full of mythical challenges.
One common theme is the idea of Percy overcoming his blindness in unique ways, often with the help of Artemis. For example, his connection with water might be enhanced in some stories, allowing him to'see' through the movement of water around him. Another theme is the relationship between a mortal (even a special one like Percy) and an immortal goddess like Artemis. It creates a lot of interesting power dynamics and emotional conflicts.
One common theme is Percy's new powers as a god. Writers often explore how he deals with the added responsibilities and abilities. Another theme is his relationships, like his friendship with old comrades in a new context or his potential romantic relationships as a god.
One major theme is the struggle between chaos and order. As the God of Destruction, Percy represents chaos, and the fanfictions often show his interactions with forces of order. Also, identity is a theme. He has to figure out who he is as this new god.
One common theme is power exploration. Since Percy becomes the God of Ice, fanfictions often delve into how he discovers and controls his new powers.
Another theme is the clash of cultures. Percy comes from his own mythological background and when he enters the God of War world, there's a lot of cultural differences. This can be seen in how he reacts to the different values and beliefs of the God of War characters, like their more brutal and direct approach to conflict.
Power and responsibility. Since Percy is taking on the role of a god slayer, he has to deal with a great deal of power. And with that power comes the responsibility of not misusing it. For example, in many fanfics, he has to make tough decisions about which gods to target and why.
