The story could be that Harry grows up alone in the Muggle world, completely unaware of his wizarding heritage until much later. He might face bullying and isolation in the Muggle school. When he discovers his true identity, he has to quickly adapt to the wizarding world all by himself. This could lead to him making some hasty and unwise decisions as he has no one to guide him.
Well, one possibility is that Percy has to learn to fend for himself in a harsh world. Maybe he discovers unique powers within himself as he faces various challenges alone. For example, he could learn to hunt and build shelters all by himself, much like a survival story.
Well, perhaps Harry would have a much darker personality. Azkaban's gloomy environment could have made him more cynical. He might start to question the very nature of the wizarding world. And when he finally gets out, he could be on a mission to completely change the way Azkaban is run, or even the whole justice system in the wizarding world. Since he grew up surrounded by the so - called 'criminals', he might realize that not all of them are truly bad.
Well, it could be about Harry and Tom becoming friends as they grow up. Maybe they learn magic together, face challenges side by side, and their friendship changes the course of the wizarding world.
The plot might involve Harry trying to figure out how he got pregnant in the first place if it's in a world where male pregnancy is not the norm. He could be alone because he doesn't want to burden his friends or family. Harry would then have to learn about pregnancy on his own, from reading books or searching the internet. He might also face financial difficulties as he prepares for the baby's arrival, but through his own determination and some unexpected help, he starts to build a new life for himself and the baby.
One possible plot could be that they become really good friends. Harry might learn a lot about the Beauxbatons culture from Fleur. They could study together, share secrets, and have adventures in the Hogwarts grounds. Fleur could also help Harry with his French, which could come in handy in some of his later adventures.
Well, perhaps it could be about Harry growing up in a world where Lily survived. They might have a special bond. Harry could learn magic from Lily in a more personal way, and she could protect him from threats that Voldemort still poses. Maybe they'd have adventures together in the wizarding world, and Lily could introduce Harry to parts of the magical community that he didn't get to experience in the original story.
Well, for this type of fanfiction, the plot might start with Percy being separated from his usual allies very early on. He'd be forced to navigate the mortal world by himself. Since he's growing up alone, he may not have the same understanding of his Greek heritage as he does in the original series. This could lead to him making different choices when it comes to using his powers. For example, instead of using them to protect Camp Half - Blood, he might use them to simply survive in a world that seems to be constantly against him.
Harry would likely be more distrustful. Without the experience of having friends or family to rely on, he'd be hesitant to open up to new people. He may also be more independent in his decision - making, since he has no one to consult with. For example, he might not wait for others' opinions when facing a dangerous situation but just act according to his own judgment right away.
A group of bandits might be the main antagonists. They see Percy as someone they can easily rob or enslave since he is all alone. Percy would then have to use his skills to outwit them.
One possible plotline could be Harry making friends with the hospital staff and other patients. They become like a second family to him, and he learns about different kinds of people from various backgrounds. Another could be Harry discovering his magical abilities while in the hospital, perhaps through some strange events that occur only he can notice, like objects moving on their own. Or maybe he uses his time in the hospital to study magic secretly, getting books sent to him somehow and practicing spells in his room when no one is looking.
