Yes, in certain fanfictions Harry Potter is made out to be Tom Riddle's brother. This is often a way for fanfiction authors to add a new twist to the story. They might do this to explore how the two characters, with their very different natures (Harry being the hero and Tom being the villain), would interact if they had such a close family relationship. It also allows for new plotlines to be developed, like how their shared heritage could affect the wizarding world. But remember, it's all part of the fan - made world and not the official 'Harry Potter' story.
In these fanfictions, the theme of acceptance is quite common. They have to accept each other as brothers despite their differences. Also, the exploration of the past is a big theme. Digging into their family's past to understand why things are the way they are in their present. And there's always the theme of adventure as they go on various magical adventures together as brothers.
There are quite a few out there. 'A Different Kind of Family' is a great one. It really focuses on how Harry and Tom, as brothers, have different personalities but still share a deep connection. It also has some interesting plot twists regarding their magical abilities and how they use them in the face of challenges.
Given that Harry has a strong moral compass, he would constantly be at odds with Tom's immoral actions. Severus, who has his own moral grey areas, would be in a unique position. He might act as a mediator between Harry and Tom, although reluctantly. Their different personalities would create a complex web of relationships. Harry's impulsiveness might be tempered by Severus's caution, while Tom's ambition could be a constant source of danger for both Harry and Severus.
A plot twist could be that their brotherhood is the key to defeating a new, powerful dark force. Harry, Severus, and Tom have to put aside their differences and grudges. Since Severus was once a Death Eater and Tom is Voldemort, this would be extremely difficult. However, their shared blood might give them unique powers when combined, which they need to figure out to save the wizarding world.
Yes, there are such fanfictions out there. However, I can't really recommend specific ones as there are so many and their quality varies greatly. You can try searching on fanfiction - specific websites like Archive of Our Own or FanFiction.net using relevant keywords to find them.
Well, in fanfiction, anything can happen. Just because it says Harry is Uryu's brother doesn't necessarily mean it's going to be a traditional brother relationship. It could be a metaphorical brotherhood, or it could be a result of some crazy plot device like a cross - over between two different universes. So, it really varies from one fanfiction to another.
At first, it could be very strained. Tom might be resentful or confused about having Harry as a father all of a sudden. But as time goes on, if Harry shows love and support, Tom could start to warm up to him. For example, Harry could help Tom with his schoolwork or magical training.
At first, it could be a relationship based on trust and mentorship. Tom, as the godfather, might teach Harry some unique magic skills. But as Harry realizes Tom's darker side, it would turn into a strained relationship full of tension and conflict. Harry would struggle between his loyalty to his godfather and his own moral compass.
Yes, there might be such fanfiction out there. The Harry Potter fandom is vast and full of creative interpretations. Some fans like to explore unusual family relationships in their fan - created stories. This concept could lead to very interesting plotlines, like how it would change the dynamics between Harry and the Death Eaters if he was related to Bellatrix in this way.
