A really cool fanfiction idea is that James Potter meets Harry Potter in an alternate universe. In this universe, James never died and he gets to see Harry as a normal, happy kid without the burden of being 'The Boy Who Lived'. They might go on adventures together in Hogwarts that are more about exploration and fun rather than fighting dark forces. Another interesting one could be where James Potter appears as a ghost to Harry Potter. He gives Harry advice on how to deal with his love life, something that James was quite good at during his own Hogwarts days.
Well, there are fanfictions where James Potter meets Harry Potter during a time - loop situation. Harry keeps reliving a day and each time James shows up in different forms to help him figure out what's going on. It's a really unique concept. Also, there could be a story where James Potter is resurrected by a powerful spell and he has to quickly adapt to the new wizarding world that Harry has been living in. He and Harry then team up to solve some new threats to the wizarding community that are emerging. And there are those fanfictions where they meet in a parallel dimension where the rules of magic are slightly different and they have to work together to find their way back to their own world.
There's 'James Potter's Legacy'. This fanfiction might explore how James' actions and reputation influenced Harry. It could show how the tales of James' heroics and his flaws were passed down and how Harry dealt with the weight of his father's legacy. Some fanfictions also blend the past and present, such as those where Harry gets to interact with a younger version of his father through time - travel or magical means.
A great 'Merlin meets Harry Potter' fanfiction could involve the two of them teaming up to solve a mystery that spans both their worlds. It could be that a dark wizard has found a way to use the magic from Merlin's time to create a new and dangerous threat. Merlin and Harry would have to combine their knowledge and skills, with Merlin's deep understanding of magic's roots and Harry's experience with modern magical threats.
Then there's 'The Love of Lily and James'. This one is more of a romantic take on their story. It really focuses on the love they had for each other. It describes their dates, their secret conversations, and how they supported each other through difficult times. It gives a very warm and fuzzy feeling about their relationship.
One interesting fanfic could be those that explore James Potter's time at Hogwarts before Harry was born. It might show his adventures with his friends, like Sirius and Remus. Another could be a fanfic where James Potter somehow gets to interact with Harry in a time - traveling scenario, which would be really cool.
I remember reading a fanfiction where James Potter's animagus form is a stag, and it's all about how he uses this form to explore the Forbidden Forest. It has some really cool descriptions of the forest and the magical creatures in it. The author did a great job of showing how being an animagus gives James a different perspective on the magical world around him.
Well, a great James Potter survived fanfiction is 'James Potter's Redemption Arc'. It could explore how his survival changes his perspective on life and death. Maybe he has to deal with the guilt of leaving his family behind in the first place. Then there's 'The Return of James Potter'. This one might show his struggles to fit back into the wizarding world he once knew, as so much has changed since his supposed death.
There's 'James and Lily: Destiny's Path'. This fanfiction delves deep into the magical world they inhabited. It not only focuses on their love but also on their roles in the fight against the Dark Arts. It includes detailed descriptions of their magical abilities and how they complemented each other.
One interesting fanfiction could be where James Potter faces his boggart which turns out to be the death of his friends. In this story, he has to find the courage to overcome his fear and protect them. It shows his growth as a character.
There are fanfictions that explore the family secrets of James Potter's parents. For example, a story could focus on a hidden magical ability that runs in their family and how it affects James Potter's life even though he may not be aware of it at first. This kind of fanfiction can add depth to the Potter family history.
One interesting fanfiction could be one where James Potter has a pre - battle encounter with Voldemort that changes the course of the First Wizarding War. Maybe in this fanfiction, James discovers a secret weakness of Voldemort that no one else knew about.
