Well, perhaps in this fanfiction, Harry goes back in time and discovers that Sirius was involved in some secret magical research. Harry then joins him in this research, which could lead to new spells or ways to fight the Dark Arts. Also, since they become mates earlier, they might influence the Hogwarts environment. They could start some sort of club or group for students to learn self - defense against the Dark Arts in a more practical way, which wasn't really available in the original story.
One possible plot point could be Harry using his knowledge of the future to save Sirius from his untimely death. For example, he might prevent Sirius from going to the Ministry of Magic that fateful night. Another could be Harry befriending Sirius even earlier in time and changing the course of their relationship. Maybe they end up working together on some secret mission against Voldemort much sooner than in the original timeline.
Obviously, Harry Potter and Sirius Black are the main characters. Harry is the time - traveler, and Sirius becomes his mate in this new timeline. Other characters like Dumbledore are likely to also play important roles, as he is always involved in matters related to Harry and the greater good of the wizarding world.
One common plot point is the discovery of a way to time - travel. It could be a new spell, a hidden device, or something left by a powerful wizard. Another is the struggle to avoid changing too much of the past. Harry usually has to be very careful not to disrupt the timeline while trying to save Sirius. For example, he can't accidentally stop something important from happening that is related to the future.
Well, one interesting plot point could be Deku using his knowledge of future events to prevent certain tragedies. For example, he might stop a major villain attack before it even starts, saving many lives. Another could be his interactions with past versions of his friends and how he has to be careful not to change things too much.
Well, sometimes in these fanfictions, a plot twist might be that Sirius goes back in time and discovers a hidden truth about his family. Maybe he finds out that there was a secret alliance or a hidden enemy within the Black family that was influencing events all along. This could completely change his perception of his family's past and his place in it. Also, he could go back in time and end up being involved in a different kind of magic that was lost in his original time, like an ancient form of magic that has the power to either save or destroy the wizarding world.
Well, one possible plot point could be the initial conflict due to their different allegiances in the wizarding world. Harry is on the side of good and Lucius has been on the side of the Death Eaters. Their relationship might start with a lot of mistrust. Another could be how they deal with the social stigma of being mates when they come from such different backgrounds. It could lead to a lot of drama within the wizarding community.
One great fanfiction with this plot is 'Time's Redemption'. In it, Harry uses a powerful time - turning spell he discovers in an ancient book. He has to face many challenges in the past, like avoiding detection from the Ministry's time - turner regulations. Another good one is 'Back to Save Sirius'. Here, Harry teams up with Hermione and they use a secret time - travel device left by Dumbledore.
There could be unforeseen magical consequences. Time - traveling is a tricky business in the wizarding world. By changing Sirius' fate, Harry might accidentally create new problems. For example, the balance of magic in certain areas could be disrupted. There might also be changes to the Hogwarts' community. Students and teachers who were affected by Sirius' situation in the original timeline might act differently.
One idea could be that Harry goes back in time to prevent certain dark magic spells from being created. He might try to stop Voldemort's rise before it even starts by influencing the earlier events related to the Dark Lord. Another plot could be Harry going back and changing the way he interacted with certain characters like Snape, which could lead to a completely different relationship dynamic. Maybe he could also go back to save some characters who died in the original timeline, like Sirius Black.
In some fanfictions, Harry goes back in time and decides to train himself better. He could seek out different magical knowledge or combat skills that he didn't have the first time around, which then changes his future interactions and battles. For example, he might learn ancient spells that give him an edge against Voldemort.
In 'Harry go back to the marauders time fanfiction', a really engaging plot point is Harry's internal struggle. He has to decide whether to interfere with the past or not. On one hand, he might be tempted to save his parents from their tragic fate. But on the other hand, he knows changing the past could have huge consequences. This conflict within him can drive the whole story. Also, his relationships with the Marauders are key. How does he fit into their friendship? Does he become a new member of their group? Or is he more of an outsider trying to help from the sidelines?
