Sure. There could be many fanfics out there with this premise. It might show how Harry would have grown up in a different family dynamic, having James as his brother. Maybe he would have been more involved in the early Order of the Phoenix activities, or his relationship with Dumbledore could have been shaped differently due to his new family connection.
One common theme is friendship. Writers often explore how Harry and James could have been friends in different scenarios. Another theme might be mentorship, as James could be seen as a mentor figure to Harry.
One idea could be to have Naruto enter the world of James Bond. Maybe he's on a mission to protect a special scroll that has secrets important to both the ninja world and the international espionage world that Bond is a part of. The fem James Bond could be initially skeptical of Naruto's abilities but soon realizes his unique skills in combat and stealth are invaluable.
I'm not sure specifically about 'james disowns harry' fanfics being extremely popular. There are so many fanfics out there that it's hard to single out ones with this exact plot as being super popular. But in the vast world of fanfiction, any plot that involves a major relationship change like this could potentially have a following.
Well, it could mean in a fan - made story (fanfic), the character James disowns Harry. Maybe there's some sort of conflict or plot development where James, for whatever reason, decides to no longer consider Harry as part of his family or group.
Love is a very prominent theme as well. The love of a father for his son is at the core of these fics. It's not just about comforting words, but also about the deep, unconditional love that James has for Harry. This love gives Harry the strength to face his challenges, whether it's fighting Voldemort or dealing with his own inner demons.
In a 'James takes Harry' fanfic, the relationship between the two would be central. We could see James teaching Harry advanced magic that he didn't get to learn in the books. For example, James was known for being a talented wizard in his own right. He could introduce Harry to spells and magical concepts that are more advanced or even lost in the wizarding world. It would also be interesting to see how they interact with other characters. Would James be friends with the Weasleys? How would he handle Snape? There are so many possibilities to explore.
I'm not aware of any such fanfic. Fanfiction often contains a wide variety of strange and inappropriate concepts, but this one seems rather extreme and goes against the nature of the original Harry Potter story in terms of the characters' relationships.
Regarding the Iggy fanfic involving Harry time travel and James' brother, one possible plot could be that Harry accidentally time travels to a period when James' brother was in a difficult situation. Harry, using his knowledge from the future, tries to help him out. Along the way, they might discover some unique magical abilities or artifacts that were previously unknown. This could also lead to a deeper understanding of the Potter family history and how it has influenced the wizarding world as a whole.
It could be really exciting. Harry's time travel might lead him to meet James' brother at a crucial moment in the past. They could form an unexpected bond and work towards a common goal, like saving someone or something important in the wizarding world.
