Well, Kakashi is the protagonist who brings the time - travel element into the story. Minato, as the leader of the team, is a crucial character. Obito and Rin play significant roles too. Obito might be a character that Kakashi has to deal with in a different way considering their complex relationship in the original timeline. Rin could be a source of motivation or a key to some events that Kakashi remembers from his own past.
Obviously, Kakashi is one of the main characters since it's about his time travel. Minato is also a central figure as he is part of Team Minato that Kakashi travels back to be with. And of course, the other members of Team Minato like Obito and Rin are likely to be important characters as well.
The main characters are Kakashi, who travels through time. Minato, the talented and respected leader of Team Minato. Obito, who has his own development and story arc within the team. And Rin, who is not only an important member of the team but also has connections to the other characters. Their interactions and how they are affected by Kakashi's time travel form the core of the fanfiction.
A really cool plot might be that Kakashi time travels and discovers a hidden conspiracy in the past that was related to Team Minato. He then has to work with his past comrades, including Minato, to uncover the truth and prevent a great disaster that he knew about from his own time.
One good plot could be Kakashi going back in time and using his future knowledge to prevent the death of his comrades in Team Minato. For example, he might be able to stop Obito from getting crushed in that rockslide. Another plot could involve him trying to change the course of the war by influencing key decisions made by his team. He could also go back and try to train himself better in the past, using the skills he's learned in the future.
Kakashi's abilities would likely be enhanced in the past. He has all the knowledge and skills he's gained in the future. So, his combat skills would be more refined. His Sharingan would be even more powerful as he would know better how to use it. He might also be able to teach his younger self some new jutsu that he learned over the years.
It could be Kakashi. Since he has such a complex backstory and is a very popular character. The story could revolve around how he interacts with Team Minato and how his presence affects their dynamic.
Probably Naruto. Since Minato is his father, he has always longed to know more about him. Meeting Minato and his team would be a dream come true for Naruto. He would be eager to hear stories from his father's past, about his training, and how he became such a great ninja. Naruto might also want to show off his own skills to his father and the rest of Team Minato.
The main characters are obviously Naruto and Minato. Naruto is the protagonist of the Naruto series, a young ninja with the Nine - Tails sealed inside him. Minato is Naruto's father, a very powerful ninja known as the Fourth Hokage. In this time - travel fanfiction, their interactions form the core of the story.
Obviously, the babies of Kakashi's team 7 would be the main characters. So, there would be Naruto's baby, Sasuke's baby, and Sakura's baby. They are the focus as the story would revolve around their lives.
The main characters are not just limited to the ones we know from the original series. There could be some side characters from the village who play important roles. For example, a medical ninja who helps take care of the babies when they are ill or injured. Also, there might be a mysterious figure from another village who has a connection to the events surrounding Team 7's babies.
Another theme is the exploration of relationships. Since Kakashi and Minato have a complex relationship in the original story, in time travel fanfictions, they can have new interactions. They might be able to understand each other better, like Minato getting to see Kakashi as a more mature and capable person if he travels to the future, or Kakashi seeing Minato's leadership in a new light if he goes back in time.
Obviously, the main characters would be the members of Team 7, which include Naruto, Sasuke, and Sakura. Naruto, with his determination and never - give - up attitude, would be a key player in dealing with the challenges of the past. Sasuke, with his powerful ninja skills and complex personality, would also play an important role. And Sakura, who has grown into a strong kunoichi, would contribute with her medical and combat abilities.
