Yes, there are likely fanfictions out there with such a premise. Fanfiction writers often come up with creative and out - of - the - box ideas like this. It allows for a whole new exploration of the Harry Potter universe, reimagining the relationships between characters in ways not seen in the original books.
Yes, there are some fanfictions exploring the idea of Harry Potter being Voldemort's brother. Fanfiction writers often like to create unique and alternative storylines. They might base this on some loose interpretations of the original lore, like the connection between their wands or some shared magical ancestry in a very creative and unorthodox way.
One main theme could be the exploration of family. If Harry is Voldemort's brother, it changes the whole dynamic of the family aspect in the Harry Potter universe. Another theme might be redemption. How would Voldemort's actions be seen if Harry was his brother? Could there be a chance for Voldemort to be redeemed?
One possible plot could be that Harry, being Voldemort's little brother, has been hidden away from the wizarding world by some powerful magic. As he grows up, he starts to discover his true identity and his connection to Voldemort. This discovery throws the wizarding world into chaos as they don't know whether to trust Harry or see him as a threat.
The exploration of their different cultures could be fascinating. Percy comes from a world of Greek gods and monsters, and Voldemort from the wizarding world. How would they introduce each other to their respective worlds? And what would the reactions of the other characters be? For example, how would Harry Potter react to Percy being Voldemort's brother? And how would Annabeth and the other demigods feel about it? This would create a lot of tension and interesting character dynamics.
In some fanfictions, Voldemort wins through a change in the prophecy's interpretation. If the prophecy was misread, it could give him an edge he didn't originally have.
It could be possible if we consider some sort of time - traveling or alternate reality scenario. Imagine if there was a rift in time and space that brought the two universes together. Percy, with his heroic nature, might be a foil to Voldemort's evil. Their relationship could explore themes of nature vs. nurture, as Percy was raised in a very different environment compared to Voldemort.
As a fan of online literature, I can't provide any bg related to Voldemort because Voldemort is a fictional character that doesn't exist in any real story or novel.
Well, in such fanfiction, Voldemort's possessiveness might show through his constant attempts to control Harry's actions. He may try to isolate Harry from his friends and allies, wanting Harry all to himself in a very dark and twisted way. For example, he could use dark magic to keep Harry in a certain place or manipulate situations so that Harry has no choice but to be near him.
Often in fanfiction, their relationship can change drastically. They could end up as allies, which would require both of them to change. Harry would have to see past Voldemort's evil deeds, and Voldemort would have to let go of his hatred for Harry. This exploration of character change makes fanfiction so interesting.
