Well, a plot might involve Harry - now James - trying to change the fate of his family. He could focus on protecting Lily in a different way than James did in the original story. Maybe he'd use his knowledge of magic from his past life to create new spells or defenses. Also, his relationship with Snape could be very different. Since he was Harry before, he might understand Snape's feelings better and try to make amends or change the animosity between them.
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.
Well, first off, James Potter is the central character now. But don't forget about Snape. Given Harry's past experiences as himself, his new identity as James could lead to a very different dynamic with Snape. Lupin would also be important as one of James' friends. And Voldemort, of course. Since Harry's whole goal might be to stop him in a new way, Voldemort would be a major presence in the story. Also, Petunia might have an unexpected role, as Harry now has a different perspective on his Muggle family.
One common theme is family. Since she's James Potter's sister, there's often exploration of her relationship with James, their parents, and the rest of the family. Another theme is identity. She has to figure out who she is within the shadow of her famous brother. For example, in some fanfics, she might struggle to find her own place in Hogwarts or in the wizarding world in general.
Yes, there are likely to be such fanfictions in the vast world of Harry Potter fan creations. Fans often come up with creative and sometimes out - of - the - box ideas, and the concept of Harry being the child of Severus and James is one of those very imaginative scenarios that some fanfic authors might explore.
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.
A major theme is the exploration of the past. Harry never really got to know his father properly. So in fanfiction, writers often take the opportunity to delve into James Potter's life. This could include his time at Hogwarts, his relationship with Lily, and how all of that shaped Harry. It's also common to see themes of redemption, especially if the fanfiction takes a different turn on James' character, perhaps showing him making amends for any mistakes he made in his youth.
One great fanfiction could be 'Lily and James: A Love Beyond'. It delves deep into their relationship before Harry was born. It shows how they met at Hogwarts, their initial dislike which gradually turned into love. The story also includes their adventures as members of the Order of the Phoenix and how they fought against the Dark forces side by side.
A great fanfiction idea might be that Hermione and James Potter's sister team up to compete in a wizarding tournament. Along the way, they face various challenges that test not only their magical skills but also their friendship. Their different personalities - Hermione's studiousness and James' sister's perhaps more adventurous spirit - could create an interesting dynamic as they strive to win the tournament.
One possible fanfiction could focus on the moments leading up to their death. It might show James trying to protect Lily and Harry until the very last moment. He could be shown using his wand to fend off Voldemort as long as he could, while Lily was huddled in a corner with baby Harry, praying for a miracle.
