One interesting plot could be James Potter using his skills to outwit new and powerful dark wizards that emerge in the wizarding world. He might form new alliances and teach the younger generation his unique magic. Another could be him exploring uncharted magical territories, perhaps finding new spells or magical creatures that change the way magic is perceived in the wizarding community.
Well, a possible plot is that James Potter never died because of some time - magic related incident. So, he gets to see how the wizarding world has changed over the years. He could struggle to adapt to new technologies and social norms in the wizarding world. And at the same time, he tries to find a way to fix the time - magic anomaly that kept him alive, while also using his old - school magic to solve modern - day wizarding problems.
One possible plot could be that Voldemort's curse backfires in a different way. Instead of killing them, it transports Lily and James to a parallel magical dimension. In this dimension, they are able to secretly raise Harry while still being alive. They could then use their knowledge of the future to train Harry more effectively and build a stronger resistance against Voldemort. Another plot might involve a powerful magical object that they discover which has the power to protect them from death spells. They could then use this object to not only save themselves but also to help the wizarding world in the fight against the Dark Lord.
The main character is James Potter. But depending on the fanfiction, other characters can become important. For example, if the story focuses on James' role in the wizarding government, there could be Ministry of Magic officials as major characters. Or if it's about his personal growth, his son Harry Potter (in a different timeline perhaps) could be a key character, and they could have interactions that shape both of their characters in new ways.
A great plot idea could be that in the fanfiction, James Potter comes back as a ghost or some kind of spectral form. He then accompanies Harry on his adventures, giving him advice and helping him in battles. They could also have heart - to - heart conversations about love and family. For example, James could share his experiences with Lily with Harry, and in turn, Harry could tell James about his own feelings for Ginny. This would not only strengthen their bond but also add a new dimension to the Harry Potter universe in the fanfiction.
One possibility is that James could play a significant role in Harry's growth as a wizard. He might teach Harry advanced magic that Dumbledore or other professors didn't cover. For example, he could pass on family - specific spells or magical techniques. This would change the whole dynamic of Harry's adventures at Hogwarts. He would also be there to protect Harry more directly from Voldemort and his Death Eaters, which would likely lead to different battles and outcomes compared to the original story.
A plot could be that James Potter travels back to the time when Voldemort was still Tom Riddle at Hogwarts. He could try to influence Riddle in a positive way, perhaps by befriending him and showing him a different path than the dark one. However, he has to be careful not to change the future too much or risk endangering his own existence and that of his family.
One plot could be that James Potter's spirit is somehow able to communicate with Harry Potter and gives him advice on how to deal with the challenges at Hogwarts, like handling difficult professors or dealing with bullies. Another could be a time - travel plot where Harry gets to meet a young James Potter and they form a bond over their shared love for Quidditch and learn from each other's experiences in different time periods.
One interesting storyline could be a continuation of the relationship between the main characters in a different setting. For example, they might find themselves in a modern-day city and have to adapt their love to the new environment. Another could be exploring what would have happened if certain events in the original story had different outcomes. This might lead to new character developments and relationships.
One interesting plot could be that they travel back to the time of the Marauders. James and Lily could meet their parents when they were young and see how different Hogwarts was back then. They might get involved in some of the Marauders' pranks and also learn some secrets about their family's past that were long forgotten.
One unique plot is in the fanfiction where James Sirius Potter discovers a hidden chamber in Hogwarts that was unknown to even his father. It contains ancient spells and secrets that he has to figure out. Another plot has him being able to communicate with the ghosts of the original Marauders, getting advice from them in his daily Hogwarts life. A third unique plot is where he is accidentally sent to an alternate dimension Hogwarts and has to find his way back while dealing with the differences in that world.
One possible plot could be a heroic sacrifice. Maybe he's facing a powerful dark wizard or a dangerous magical creature. In the heat of the battle, he makes the ultimate choice to save his friends or family, and in doing so, loses his life. This would be a very bittersweet ending, full of both sorrow for his death but also pride in his selfless act.
