A demigod who has the power to communicate with the dead. Percy adopts this troubled soul who is constantly haunted by the voices of the deceased. Percy has to help them come to terms with their power and find a way to use it for good. This would be an interesting dynamic as Percy is used to dealing with more physical threats, while this demigod's problems are more of a psychological and spiritual nature. They could go on quests to places like the Underworld to better understand the demigod's power and how it relates to the world of the living and the dead.
I think a character with the ability to control time would be really interesting. Imagine Percy having to deal with a demigod who can accidentally mess up the time continuum. It would create all sorts of wacky situations at Camp Half - Blood. Like, one moment they're having breakfast, and the next, it's suddenly midnight because the adopted demigod made a time - related mistake.
A demigod who is a descendant of Hecate but has no idea how to use their magic properly. Percy adopts this demigod, and they have to learn about magic together. Since Percy is more of a sword - and - water - powers kind of guy, it would be a journey of discovery for both of them. This demigod could bring a whole new element of mystery and magic to Percy's life, and they could encounter all kinds of magical creatures and challenges that Percy has never faced before.
One challenge could be dealing with the child's past traumas. If the child has been through a lot, like being orphaned or facing monster attacks on their own, Percy would have to help them heal. He's not a trained psychologist, so it would be difficult for him to know exactly how to handle it.
One idea could be that Percy adopts a young demigod who has a very rare and powerful ability. Percy has to teach this new demigod how to control their powers while also protecting them from monsters who are after the new kid because of their potential. Another could be that the adopted demigod is from a different pantheon entirely, which causes some interesting cultural clashes and misunderstandings within the Camp Half - Blood environment.
One idea could be that Percy discovers a demigod child who has been abandoned in the mortal world. He decides to adopt the child to protect them from monsters and to give them a proper home at Camp Half - Blood. He then has to teach the child about their demigod heritage and how to use their powers.
In a 'Percy Jackson adopts Harry Potter' fanfic, the plot could start with Percy being on some kind of mission that crosses into the wizarding world. He stumbles upon Harry, who is alone and vulnerable. Percy decides to adopt Harry because he sees the same kind of determination and courage in Harry that he has. As they journey together, they exchange knowledge. Percy teaches Harry about Greek mythology and combat skills, while Harry shares his knowledge of magic. They form a bond that helps them face threats from both magical and mythological creatures, and they might even team up to fight against a common enemy that is a threat to both their worlds.
In a fanfic, perhaps Percy and his friends accidentally stumble upon Medusa's lair while on a quest. But instead of immediately attacking, Medusa offers them a deal. She says she will give them a valuable clue to complete their quest if they help her get revenge on one of the minor gods who wronged her in the past. Percy and his friends then have to decide whether to trust Medusa or not.
It could be a child of a minor god who has been overlooked. Maybe the child of Hecate, a young demigod with some really interesting magic powers that Percy and Artemis see potential in.
In this fanfic, Percy would be like an older brother to Harry. He would take Harry everywhere with him, whether it's exploring the forest around Camp Half - Blood or going on a quest. Harry would look up to Percy and learn from him. They would also have some funny moments, like when Percy tries to use a wizard's wand and fails miserably, or when Harry tries to swim as well as Percy but can't. Their relationship would be based on mutual respect and the shared experience of being different from the normal humans in their respective worlds. And they would support each other when facing challenges, whether it's a new monster for Percy or a new dark wizard for Harry.
Percy could be developed by showing his confusion at first. He's used to being a son of Poseidon, so being a son of Khione throws him off. He might struggle with learning new powers and how to use them effectively. For example, he accidentally freezes his own feet when he tries to use ice powers for the first time.
Well, it's hard to say for sure. Just because someone is named Percy Jackson Drew doesn't necessarily mean they like Percy fanfic. However, if they are a big fan of the Percy Jackson series, there's a good chance they might enjoy reading fan - created stories. Fanfic often offers unique perspectives and takes on the original story that can be really interesting for fans.
One idea could be that Percy discovers a magical blue food that gives him the ability to breathe underwater even better than normal. For example, he could find blue seaweed - like candy that when he eats it, his gills work more efficiently and he can communicate with sea creatures more clearly.
