Just use the relevant keywords in the search bar, and you might find some interesting stories exploring the relationship of Harry being James' cousin.

In such a fanfic, perhaps a villain manipulates time and alters the memories of James and Lily. They might be living in a different reality where Harry doesn't exist in their minds. Harry could then embark on a journey to find the source of this alteration and restore his parents' memories. He could encounter various allies and enemies along the way, all while trying to come to terms with his parents' current state.

Well, perhaps the plot could revolve around the family secrets that are uncovered when it's revealed that Harry and Caroline are cousins. There could be a dark family history that affects both of them. Harry might try to protect Caroline from any threats related to this new - found family connection. And Caroline could bring a new perspective to Harry's world, as she may not be as used to the wizarding ways as he is. This could create a lot of interesting interactions and storylines.

One possibility could be that Lily uses some kind of magic, perhaps a very powerful and rare spell. Maybe she does it out of a sense of protecting James from the pain associated with Harry. In the fanfic, it could lead to a lot of confusion for James. He might start a new life without the knowledge of his son, and then as the story unfolds, there could be a series of events that slowly make him start to remember bits and pieces. For example, he might encounter people or objects that were related to Harry, which would trigger his subconscious.

One possible plot could be that Harry, having experienced so much loss and understanding the importance of family, decides to adopt his cousin. Maybe his cousin has also faced some difficult situations, like being neglected at home. Harry takes him in and starts to teach him about the wizarding world, creating a bond that was previously unthinkable between them.

The plot could involve James and Lily giving Harry away to a powerful wizard who has the ability to hide Harry's magical signature completely. This wizard is an old acquaintance of Dumbledore, and they believe that under his care, Harry will be safe from Voldemort's clutches. They sacrifice their parental rights to ensure Harry's safety.

Well, often there's the discovery of their relation which is a big plot point. It's usually unexpected and throws both characters for a loop.

One common theme is family loyalty. Since they are cousins, the stories often explore how they support each other through thick and thin in the wizarding world. Another theme is the discovery of hidden powers or secrets. Maybe the cousin has a secret ability that James helps uncover, or vice versa.

The plot could involve Bianca, Rose and their cousin uniting to save the Charmed family from a new and powerful enemy. Maybe they are initially underestimated because they are younger or less experienced, but they prove their worth through their unique magical abilities and strong bond.

One possible plot could be that Harry Potter's long - lost cousin somehow ends up in the world of Bleach. Maybe they have some unique magical abilities that are a blend of the wizarding world and the spiritual powers in Bleach. They could team up with Ichigo to fight against a common enemy, like a dark wizard who has also dabbled in the forces of Hollows. This would bring together the magic of Harry Potter and the action - packed battles of Bleach in an interesting way.
