What would be the plot in a 'Harry Potter is reborn's brother fanfiction'?

One possibility is that he would use his prior knowledge to prevent the tragedies that befell his family. He could also have a different dynamic with Sirius and Remus, as he'd be part of James' inner circle from the start.

In this fanfiction scenario, Harry Potter might change in several ways. His perspective on life and death could shift. Knowing that his brother has some sort of'reborn' aspect could make him question the finality of death more. He could also become more empathetic towards those who have lost loved ones. Emotionally, he might be more stable as he has a family connection now. This new bond could also make him more willing to take risks in the name of protecting his brother, which is a different kind of motivation compared to just fighting Voldemort for the sake of the wizarding world. Additionally, he may develop new magical abilities or skills as a result of the influence of his brother's unique situation.

One possible plot could be that as a Lannister, Harry would be thrust into the complex political web of Westeros. He might use his knowledge from his past life to outwit his enemies within the Lannister family, like Cersei or Joffrey if they showed signs of the same kind of tyranny as Voldemort. He could also try to reform the Lannister's reputation which was often marred by their self - serving actions.

One possible plot could be that Harry would grow up in a very different environment. He might be influenced by the Malfoy family's pure - blood supremacist views at first. But then, as he discovers his own values, he could face a huge internal conflict. He may also have a different relationship with the other Hogwarts students. For example, he might not be as close to Ron and Hermione as in the original story because of his family ties to Draco.

Well, perhaps in this fanfiction, Harry and Pansy's family has some dark secrets. As Harry is her twin, he could be involved in uncovering these secrets. This might lead to him having a more complex relationship with the Dark Arts. He may be tempted by the power it offers, but his good nature, which is still there despite his Slytherin background, would keep him from fully embracing it.

Well, it could be that Harry, as James' brother, discovers that there were more secrets about his first life than he thought. Maybe he finds out that there was a hidden power within him that was never fully awakened in his previous life. This new discovery could change the way he approaches magic and his role in the fight against the Dark Arts, and it might also lead to a different ending to the battle against Voldemort.

One possibility could be that he would bring his magical skills into the world of Westeros. He might use magic secretly to gain an edge in battles, like creating distractions or protecting himself and his allies. For example, he could use a shielding charm during a skirmish with the wildlings.

One interesting plot could be Harry being reborn as a Stark and using his magical knowledge in the world of Westeros. He could secretly use magic to protect his family from the various threats like the Lannisters or the White Walkers. Maybe he uses a spell to enhance the strength of the Stark soldiers' weapons.

He might be more confident from the start. In his past life, Harry grew up without his parents and had a difficult childhood. But as James' brother, he would grow up in a loving family environment. This could make him more outgoing and less hesitant in social situations.

In the original story, Harry often felt alone in his battles. But with an OC as his brother, there would be a constant ally. The OC could have different relationships with the teachers too. Suppose the OC has a particular interest in potions like Snape. This could lead to a different kind of mentorship and perhaps change Snape's view of the Potter family. And when it comes to the final battles, the OC could bring in additional magical artifacts or allies that were not part of the original story, completely changing the way the fight against Voldemort unfolds.
