What are some interesting elements in 'gotta get back to the past fanfiction'?

It really depends on the source material of the fanfiction. If it's based on a superhero story, it could be the superheroes themselves trying to go back and prevent a villain from getting power in the past. Or if it's a school - based story, the students might be the ones traveling back. Sometimes it can also be a side character from the original story who gets the chance to go back and change things.

A 'get back home' fanfiction might involve a character from a post - apocalyptic world. They've been separated from their family and hometown. They journey through dangerous wastelands, fight off bandits, and finally make it back home only to find it changed but still full of the love and memories they held dear.

One interesting plotline could be Naruto using his future knowledge to prevent certain tragedies in the past. For example, he might stop the Uchiha massacre. Another could be him training his younger self more effectively, leading to a much stronger Naruto earlier on.

Another plotline could be Naruto influencing the relationships between characters. He could try to bring Sasuke back to the village much earlier in the timeline, preventing a lot of the pain and conflict that occurred between them. Or he could help his parents, Minato and Kushina, in ways that would change the future of the entire Hidden Leaf village.

One interesting plot twist could be Naruto having the knowledge of future events and using it to prevent certain tragedies. For example, he might stop the Uchiha massacre by revealing the truth about Itachi's situation earlier. Another could be Naruto changing the way he approaches his training, leading to him achieving new forms of power much quicker.

One idea could be Harry exploring a new magical realm on his own and learning unique spells there. Maybe he meets a group of outcast magical creatures who help him on his journey.

Communication is key. In most cases, people who got their ex back had an open and honest conversation about their feelings and what went wrong in the relationship.

There was a couple in college. They broke up when they graduated as they had different career paths. The girl wanted to travel and work abroad while the boy had a job offer in their hometown. Years later, they both achieved their career goals and met at a college reunion. They found that they had both changed in ways that made them more compatible and they got back together.

The 'back in black' part might imply a certain style or theme. Maybe it's about a character coming back in a cool, edgy way, like with a new look or attitude. It could also be related to a specific plot device where something that was lost or gone comes back in a big, impactful way.

One interesting plot twist could be when a character who was originally a minor antagonist in the original series becomes a key ally in the 'back to the past' scenario. For example, in some fanfictions, Draco Malfoy might end up joining Harry's side early on, changing the whole dynamic of the story. Another could be when a major event from the original series is prevented, like Sirius Black's death. This creates a whole new set of consequences and relationships that the author can explore. And sometimes, the way magic is used in these fanfictions can be a plot twist. Maybe a character discovers a new type of magic that wasn't in the original books, which gives them an unexpected advantage in the 'back to the past' world.
