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 plot could be about the babies' growth and development in the ninja world. They start to learn about the different clans and jutsus from a very early age. For example, Naruto's baby might be super curious about the Uzumaki clan's secrets, and Sasuke's baby could show an early inclination towards the Sharingan and the Uchiha clan's history. This would be a story of their journey from being innocent babies to potential great ninjas.
One interesting plot could be the team facing a new and extremely powerful enemy that forces them to develop new jutsus and strategies. For example, a villain who can manipulate time, making their regular combat skills ineffective.
Kakashi is often a favorite. His cool and mysterious demeanor, along with his powerful jutsu, make him a central and exciting character in fanfiction. He has a lot of room for backstory exploration.
Well, if Team Minato meets Team Kakashi in a fanfiction, it could lead to some epic battles or friendly competitions. Maybe they would have a sparring match to see which team is stronger. Team Minato with their speed and unique jutsus, and Team Kakashi with their diverse skills. Or they could collaborate on a mission, with Minato's leadership guiding both teams. It would be exciting to see how the different personalities interact, like Obito from Team Minato and Kakashi from Team Kakashi. They have a complex history that could be explored further in such a meeting.
One possible replacement could be Gai. He is a strong and enthusiastic ninja who has a friendly rivalry with Kakashi. He could bring a different kind of training style to Team 7, focusing more on physical and direct combat training, which would contrast with Kakashi's more laid - back and strategic approach.
At first, Kakashi might try to distance himself from Team 7's possessiveness. He values his independence and doesn't want to feel smothered. However, as he realizes that their actions are coming from a place of deep love and loyalty, he starts to accept it more. He may even start to rely on them a little bit, for example, allowing them to help him with his paperwork or other small tasks that he usually does alone. This shows a new level of trust and closeness between them.
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.
Maybe. If the fanfiction stays true to Kakashi's character in their eyes, they might approve. For example, if it shows his loyalty and skill, they could be okay with it.
