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.
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.
The concept is popular because it allows fans to fill in the gaps in the original story. The anime and manga may not fully explore all aspects of Kakashi's feelings for Team 7. Fanfiction gives the opportunity to go deeper into their relationships. For example, how does Kakashi really feel when Sasuke leaves the village? What does he do behind the scenes to support Naruto's growth? These are the kinds of things that fans love to write about and read in fanfiction.
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.
One interesting story could be about Kakashi taking Team 7 on a special mission that involves time travel. They end up in the past and have to interact with their own predecessors. It's full of action and character development as they see how things used to be.
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.
In a 'Team 7 meets Anbu Kakashi' fanfiction, it's possible that they get involved in a dangerous mission together. Anbu Kakashi would be leading the team. His Anbu experience would come in handy in terms of stealth and quick decision - making. Team 7 would have to learn to adapt to his more strict and secretive Anbu - style leadership. They might face enemies that are much stronger than what they usually encounter, and Kakashi would have to protect them while also teaching them how to fend for themselves in such high - stakes situations.
A fanfiction might focus on how Kakashi's love for Team 7 is expressed through his daily interactions. He could be constantly giving them small gifts or words of encouragement. For example, he gives Naruto a special kunai that was passed down in his family. For Sakura, he might offer advice on how to improve her medical ninjutsu skills. And for Sasuke, he could share his own experiences of dealing with a thirst for power in a more positive way.
One possible plot could be that Team 7 stumbles upon a young Kakashi during a time - travel mission. They might initially be shocked to see their sensei as a young boy. Naruto, being Naruto, would probably be super excited and try to befriend young Kakashi right away. Sasuke might be more reserved but also curious about this version of Kakashi. Sakura could be in awe and try to take care of him in a way, seeing as he's just a kid. They could end up having to protect young Kakashi from some sort of danger in the past while also learning valuable lessons about their own sensei's past.
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.
