In the fanfiction where George and Fred are Harry's brothers, how does their relationship affect the overall plot?

It changes the dynamic a lot. Since Fred and George are so creative and bold, they could influence Harry to be more like them. In the original story, Harry often felt alone, but with them as brothers, he'd have a built - in support system. They might help him with his studies in a more unorthodox way, using their own unique knowledge. Also, when it comes to fighting Voldemort, they could be right by his side, adding their own brand of magic and courage to the fight.

Well, their relationship could add a whole new dynamic to the plot. If Naruto is Tohru's brother, he might bring his ninja skills and sense of justice. He could protect Tohru in a more assertive way than in the original story. His presence might also attract different kinds of enemies or allies. For example, Naruto's known enemies in his own world could potentially cross over and target Tohru to get to him, creating more conflict.

It can create a lot of drama. For instance, it can lead to a rift between Harry and Ginny's friends who might be on different sides. Some friends might side with Ginny, thinking she has valid reasons for the rejection, while others might support Harry and try to get them back together.

Often, in these fanfictions, Hermione's intelligence complements the twins' creativity. Her knowledge of magic and books could be used to enhance their pranks or business ideas. Their relationship might develop as they work on various projects together. It could be that they find themselves relying on each other more and more, and feelings start to grow from that mutual trust and respect. The twins might be the first to realize they have deeper feelings for Hermione as they see her in a different light compared to other girls at Hogwarts.

George and Fred could develop a stronger sense of duty. As Harry's brothers, they would be more involved in the fight against the dark forces. This might make them less carefree and more focused on the greater good. They could also become more strategic in their actions, planning their pranks and magical inventions to also serve as defenses or ways to gather information. And they may even develop a new level of respect for authority, at least to some extent, as they realize the importance of the institutions fighting against Voldemort.

Maybe Harry notices some small physical differences. For example, one of them might have a slightly different hair part or a unique freckle pattern.

If Naruto is Bella's brother in this fanfiction, it could completely rewrite the Twilight saga. His upbringing in the Hidden Leaf Village would give him a different perspective. He might introduce some of the ninja concepts like chakra to the Twilight world. His relationship with Bella would also mean that he'd be involved in her love story with Edward, perhaps trying to understand Edward's motives more deeply or even challenging him to prove his love for Bella.

It changes it a great deal. Firstly, the Weasley family connection to Harry becomes much more complex and direct. Harry would grow up in a very different environment, surrounded by the Weasley's chaos and warmth from the start. His relationships with Ron and Hermione might also develop differently as he would be part of the Weasley family in a more fundamental way.

The relationship develops in a way that they understand each other's limitations better. George, being carried, realizes that he can count on Fred in difficult situations. Fred, on the other hand, gets to see George in a more vulnerable state. This newfound understanding makes them communicate more openly. They start to plan their future business ideas with more cooperation, knowing that they can support each other through any challenges that come their way in the wizarding world.

His quitting potions could open up new storylines. He might have more time to explore other areas of magic or get involved in different adventures. For example, he could start an independent study of a unique form of magic that was not possible when he was occupied with potions. This can add more variety to the fanfiction plot.
