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.
In some fanfictions, there could be a situation where a mysterious magical being intervenes. This being, seeing the potential good that Lily and James can do, saves them from Voldemort. Their survival then causes a ripple effect in the wizarding world. They might start a new school of magic that focuses on both light and dark magic in a balanced way. Harry grows up in this new environment, learning from his parents and other great wizards. This could lead to a very different outcome in the fight against Voldemort as they have a whole new approach to magic and a united front against the Dark Arts.
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.
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.
Some fanfics have the plot where James and Lily travel back to their school days. It's interesting to see how they handle seeing their younger selves and friends. They can also try to prevent certain events that led to bad things in the future. For example, they might try to stop a particular argument between friends that later had far - reaching consequences. It's full of character growth and self - discovery.
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.
If Lily and James survived, Harry would grow up with a very different sense of security. He wouldn't have the same orphan - like feelings and the need to prove himself as much. He might be more confident and less reckless in his actions. His relationship with his parents would shape him into a more well - rounded wizard, as he'd have their guidance and love from the start.
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 plot could be Snape seeing Lily and James during a Hogwarts event. Maybe it's a Quidditch match and he watches their interactions. He could be filled with a mix of jealousy and longing as he sees James showing off to Lily. Another plot might involve Snape seeing them in a more private moment in the library. He overhears their conversation about their future plans and it makes him realize how much he has lost. There could also be a plot where Snape has a vision of them through a magical object and it haunts him, making him question his own actions and decisions in relation to Lily.
There could also be a plotline where their pregnancy is put in danger. Maybe there are dark forces at work in the wizarding world that target them because of their unborn child. This can create a lot of tension and drama, as they have to fight to protect their family. It can also be a way to explore the darker side of the Harry Potter universe and how Lily and James would handle such threats while being pregnant.
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.
There are fanfictions where their pregnancy is a time of great hope in the wizarding world. It could be set during a time of unrest, and their unborn child is seen as a symbol of a new beginning. James and Lily might be shown having deep conversations about how to raise a child in such a complex world, with Lily emphasizing the importance of love and kindness.
