Well, a possible theme is the exploration of hidden powers. When Harry is a loner in fanfiction, he may be more in tune with powers he didn't know he had before. Also, there could be a theme of redemption. Maybe he's trying to atone for something in his past while being alone, and this solitude gives him the space to do so.
It often weakens his relationships with Ron and Hermione. Instead of relying on them, he may distance himself. For example, he might not share his problems with them as he used to.
He could be a loner because he lost someone very close to him. This loss makes him shut everyone else out as he feels that no one can understand his pain. For instance, if Annabeth were to die in some tragic way, Percy might retreat into himself and avoid the company of others.
A school project or event could also be a catalyst for change. If Percy is forced to work with a group of students on a project, he might start to open up as he gets to know them better. The shared goal of doing well on the project could help break down the barriers. And if it's a school event like a talent show, Percy might find his niche and gain some confidence, which would attract others to him.

For example, if he has a special power, he might be afraid of being discovered or misunderstood. Maybe he comes from a different background that his classmates can't relate to, like a family with a strange heritage. Another reason could be that he has been bullied in the past and has withdrawn as a result.
One way is to have Percy constantly pushed aside by his peers at Camp Half - Blood. For example, they might be jealous of his powers or his close relationship with certain gods.
