He might try to prove himself. Naruto has always been a determined character. So he would likely strive to show his family that they are wrong about him. He could do this by achieving great things in the ninja world, like mastering new jutsus or completing difficult missions.
It depends on the type of fanfiction. If it's an action - oriented one, the reader could be in the middle of a battle between different AU Sanses and Gaster. They might have to choose sides or try to stop the fighting. In a more comical fanfiction, there could be a lot of humorous situations, like the Sanses making jokes at each other's expense while Gaster just shakes his head in the background.
Yes, there are quite a few. You can start by looking on popular fanfiction websites like Archive of Our Own (AO3). There you'll find a variety of stories with different plotlines. Some might focus on adventure where the fem reader goes on quests with the Sanses from different AUs. Others could be more about friendship or even budding romances in a very innocent and heart - warming way.
Well, the reader might experience a whole new world of adventure. The Sanses from different AUs could have unique personalities and abilities. For example, an Underfell Sans might be more aggressive compared to a classic Sans. And the Gasters could bring in some mystery and scientific elements. The reader could get involved in their stories, help them solve problems or just be a witness to their daily 'lives' in the fanfiction world.
One common theme is the 'opposites attract' concept. Given sakusa's quiet and clean - freak nature and atsumu's more energetic and sometimes messy personality, this contrast often forms the basis of their relationship in fanfictions. Another theme is their mutual growth. They help each other become better players and people in many stories.
In fanfiction where Naruto is hated by his family, it could be a very dark and angsty take. Maybe the author wants to explore the idea of Naruto facing even more hardships on top of being an outcast in the village. It could lead to a very different Naruto, one who is perhaps more bitter or desperate for acceptance outside of his family unit.
One common theme is discovery. The fem reader often discovers the different AUs and the Sanses within them, which is like exploring new worlds. Another theme is friendship. They build relationships with the Sanses that range from friendly banter to deep, meaningful connections. And sometimes, there's a bit of mystery as the reader tries to figure out the rules and differences in each AU.
Adaptation is also a big theme. The fem reader has to adapt to the different and sometimes strange situations in the AUs. For example, in some AUs, the laws of physics might be different or the social norms are very distinct. And then there's the theme of self - discovery. Through her interactions with the sanses, the fem reader often learns more about herself, her strengths, and her weaknesses.
Naruto could try to communicate. He could sit down with his family members and try to understand why they hate him and also explain his side of the story.
One popular type might be the ones that focus on their rivalry turning into friendship and then something more. For example, there could be a fanfiction where they start off competing for a spot on the team but gradually realize they have a deeper connection. Another could be set in an AU (alternate universe) where they meet in a completely different context like at a music concert and their relationship blossoms from there.
