One common theme is family. The relationship between Harry and his brother is explored, whether it's a loving bond or a more complex, conflict - ridden one. Another theme is identity. The brother often has to figure out his place in the wizarding world, especially in the shadow of Harry. For example, in some fanfictions, the brother may struggle with being compared to Harry all the time.
There could be. In fanfiction, the sky's the limit. Since this is a 'harry older brother of bwl' fanfic, his powers could be something that sets him apart from the original Harry. For example, he might have a power that is connected to the family's heritage in a deeper way. It could be a power that was dormant in the original story but is now awakened because of his new role as an older brother. This could lead to all sorts of interesting plot developments, like him having to learn to control this new power while also dealing with the responsibilities of being an older brother.
Maybe the older brother could be a protector. He might use his magical skills to keep Harry out of trouble at Hogwarts. For example, when Harry faces difficulties with Snape, the older brother could step in and smooth things over.
There are quite a few out there. 'The Potter Brothers' is a great fanfiction where the brother is a bit of a rebel. He often gets into trouble but also has a heart of gold. It's interesting to see how he interacts with Harry and the other characters. Then there's 'Harry and His Forgotten Brother' which tells a story of a brother who was lost in the magical world for a long time and how his return impacts Harry and their family's story.
Well, a cool plotline could be that the twin brother has a relationship with a character that Harry doesn't really interact with much in the original series. Say, he becomes friends with a Slytherin who has a different view on the wizarding world. This friendship could bridge the gap between the houses in a way that Harry's relationships in the original story don't. It could also lead to the twin brother having a different perspective on the ongoing conflict between good and evil in the wizarding world.
Obviously, Harry and his twin brother are the central characters. But other popular characters can include Hermione and Ron. They might interact with the twin brother in different ways compared to how they interact with Harry. For example, Hermione might help the twin with his studies more because he has a different learning style. Dumbledore is also often a key figure. He could have different plans for the twin brother, like entrusting him with a special mission that is different from Harry's.
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.
