Itachi is a very popular character in these fanfictions. In alternate timelines, fans explore what could have happened if he hadn't carried out the Uchiha massacre. Maybe he could have been a positive force in the Uchiha clan's growth and in the overall ninja world. Another popular character is Jiraiya. In different timelines, his influence on Naruto could be altered, or he could have different adventures that change the course of the ninja world.
One interesting concept could be a timeline where Naruto fails to bring Sasuke back. This would lead to a very different Konoha, with Naruto perhaps being more jaded and Sasuke's actions having far - reaching consequences for the ninja world. Another concept might be a timeline where the Akatsuki actually succeeds in their goals, which would completely reshape the power dynamics and politics of the ninja world.
First, decide on the point of divergence from the original timeline. It could be a decision made by a character, a historical event, or something else. From there, map out how that change would impact subsequent events and shape the story in a new way. Consider how characters' motivations and goals might shift as a result.
Well, first, you need a clear idea of what event or decision will cause the alternate history. From there, think about how that one change would lead to different developments in different areas. Maybe technology progresses differently or major wars have different outcomes. Also, consider how people's lives and values might shift.
In an alternate timeline, Steve Rogers and Tony Stark might be closer friends from the start. Maybe they met during a different event and bonded over a shared love for some old - fashioned values. Their relationship could be less strained, which would also affect how the Avengers as a whole operate. Without their initial bickering, the team could be more united earlier on.
One interesting plot idea could be that in the alternate timeline, Tony Stark never becomes Iron Man. Instead, he devotes his life to clean energy research and Pepper Potts takes on a more superhero - like role, using Stark tech to fight crime. Another idea is that the Avengers lose the Battle of New York in this timeline, which leads to a dystopian world where the Chitauri rule, and the remaining heroes have to form an underground resistance.
Hermione Granger remains very popular. In alternate timelines, she can often be portrayed as even more powerful or having different roles. For example, she might be a leader in a wizarding revolution. Harry Potter himself is also a central figure in most of these fanfictions, with his story being tweaked in various ways. And Draco Malfoy is often a popular character as well. His complex personality allows for a lot of interesting character development in alternate timelines, such as him becoming an ally to Harry instead of an enemy.
Kirk is often very popular. He's a classic character, and in alternate timelines, writers can explore different aspects of his leadership and his relationships. Spock is also a favorite. His logical mind and his relationship with Kirk can be re - explored in interesting ways. Uhura is another popular character. In alternate timelines, she might have different roles in communication or diplomacy, which is exciting to read about.
One interesting concept is the re - imagining of character relationships. For example, how Kirk and Spock's friendship might develop differently in an alternate timeline. Another concept could be different technological advancements or setbacks. Maybe in an alternate timeline, the Federation has a different approach to warp drive technology. Also, exploring how different historical events in the Star Trek universe, like first contact with certain species, could have occurred in an alternate way is really fascinating.
One interesting plot twist could be if Harry was sorted into Slytherin instead of Gryffindor. This would completely change his relationships and the way he is perceived in the wizarding world. Another could be if Voldemort had a change of heart early on and decided to abandon his dark ways. It would be a huge shift in the entire story's dynamic.
