One possible plot could be that Percy is in a fierce battle against a powerful and malicious monster. The monster manages to land a lucky and brutal strike that gouges out Percy's eye. After losing his eye, Percy has to deal with not only the physical pain but also the psychological trauma. He might struggle with self - doubt and fear, but eventually overcomes these feelings and becomes even stronger, learning to fight with his new handicap and relying more on his other senses.
It could be an old enemy like Kronos. Kronos is extremely powerful and cruel. He might target Percy's eye as a way to weaken him both physically and mentally. By taking away Percy's eye, Kronos hopes to make Percy less effective in battle and to shatter his confidence, which is crucial for leading the demigods against him.
He would become more cautious. Losing an eye would be a harsh reminder of his mortality. He'd likely train harder to make up for the loss of vision in one eye. For example, he might practice more with his sword in the dark to get used to fighting with limited sight.
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.
There's also the possibility that it's an accidental injury caused by one of Naruto's friends during a training session gone wrong. For example, Sasuke could accidentally unleash a jutsu that hits Naruto's eye while they are sparring.
It could be a new, mysterious ninja from a far - off land. This ninja might have a vendetta against Naruto for some reason, like Naruto interfering in their plans before. They could be extremely powerful and use some sort of dark jutsu to target Naruto's eye specifically.
Well, one possibility could be that Naruto loses his eye in a battle against a powerful new enemy. This loss could lead to him struggling with his self - confidence and his ninja abilities at first. But then, he might train hard to adapt and develop new skills that rely less on his sight, like enhancing his other senses.
One consequence could be that Naruto becomes more isolated. He may feel like he's a burden or that he's not as strong as he used to be. However, this could also lead to him becoming more determined to overcome his disability. He might train harder to develop his other senses, like his hearing and sense of smell, to make up for the loss of his eye. This could ultimately make him a more well - rounded and unpredictable fighter.
Well, it could be due to a powerful enemy attack during a fight in Wave. Maybe an enemy with a sharp weapon or some dangerous jutsu managed to strike Naruto's eye.
One possible plot development could be that Naruto loses his eye in a battle against a powerful new enemy. This might lead to him having to adapt his fighting style, perhaps relying more on his other senses like hearing and smell. He could also experience self - doubt and a crisis of confidence, but then use this setback as motivation to become even stronger.
