One possible plot could be that James, Lily, and Albus travel back in time to the Marauder's era. They could interact with the young versions of their family members, like Sirius and Remus. Maybe they try to change some small events to prevent future tragedies without messing up the timeline too much.
Another plot might involve them traveling to a time when a great magical discovery was made. For example, they could go back to the time of the founders of Hogwarts. There, they could learn ancient magic that was lost over time. Albus, being the curious one, might try to figure out how to bring that magic back to their own time. James could be more interested in the adventure aspect, while Lily might be focused on the historical and ethical implications of using such magic.
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.
In some Albus Severus time travel fanfiction, the plot involves him going back to the time of the founders of Hogwarts. This is fascinating because he gets to interact with the likes of Godric Gryffindor and Salazar Slytherin. He might have to choose sides in an old conflict or even try to prevent the split between the houses. It's a really cool concept that explores the roots of Hogwarts and the wizarding world. Also, there are plots where he travels to a time when dark magic was on the rise and he has to fight against it using his knowledge from the future.
One common theme is the idea of changing the past. Since they are time traveling, there's often a temptation or need to change certain events. For example, in some stories, Albus might want to prevent some tragedy from happening to James and Lily. Another theme is self - discovery. By seeing their family members in a different time, they learn more about themselves and their family history.
There's also 'Time's Twist'. In this fanfiction, James accidentally gets sent back in time. He meets Lily before they were together and has to figure out how to get back to his own time while also not messing up the timeline that leads to his own existence. It's full of adventure and some really sweet moments between the characters.
James would have the opportunity to see his parents and how they were in their youth. This could make him more appreciative of his family heritage and the values they held. He might also learn from his father's mistakes or heroic deeds. Lily, seeing the past, could be inspired to fight for equality and justice in the wizarding world even more. She could use the knowledge of the past to make changes in the present. Albus would be like a sponge, soaking up all the knowledge and experiences. He could form strong bonds with the people they meet in the past, which would influence his character development. His view of the world would expand, and he might come back to his own time with a new set of skills and a more developed moral compass.
James might be very adventurous during the time travel. He would be eager to explore different time periods and get into all sorts of situations. His boldness could lead him to take risks that might either save the day or get them into trouble. For example, if they were in a dangerous situation in the past, he might be the first to jump into action without fully thinking it through.
One possible plot could be that Harry travels back in time and meets James' twin. Maybe they team up to change some events in the wizarding world. For example, they could try to prevent Voldemort's rise to power earlier on. This would create a whole new set of adventures and challenges for them.
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.
James in fanfiction usually exhibits leadership qualities. He might lead his friends into some exciting but sometimes risky adventures. Albus can be a bit of an enigma. He may be quiet at times but is full of deep thoughts and is constantly trying to figure out his place in the wizarding world. Lily is portrayed as having a sharp mind and a kind heart. She can be a mediator between her brothers when they have disagreements, and she also shows great courage when faced with challenges.
I really like the fanfiction titled 'James, Albus, and Lily: A New Generation'. It shows how they carry on the Potter family legacy while also forging their own paths. It has interesting plot twists and a great deal of character development, especially in how they interact with their friends and deal with the pressures of being Potters.
