It could also be due to a misunderstanding. Perhaps there is some misinformation spread about Sasuke in the fanfiction, like false rumors that he has a hidden and malevolent plan. Naruto, being someone who values their friendship deeply, would be scared at the thought of Sasuke turning into an enemy because of these untrue stories.
Definitely. Fanfic writers often play around with different character dynamics. Sakura being scared of Sasuke can be a part of exploring their relationship in a non - canonical way. It could be due to Sasuke's cold and distant nature, especially after the Uchiha massacre. This fear could be the starting point for many different plotlines in fanfics, such as Sakura trying to understand Sasuke better to get over her fear or Sasuke realizing the impact of his actions on Sakura.
In a fanfic, Sasuke's association with dangerous elements might make Sakura scared. For instance, if he teams up with a group of rogue ninjas. Also, his emotional state could play a role. If he is consumed by revenge and his anger is constantly boiling over, Sakura, who cares about him, might be scared of his self - destructive tendencies. Additionally, if Sasuke were to develop some sort of mind - control ability that he struggles to control, Sakura would surely be frightened.
It makes their relationship more tense. Normally, they have a complex but strong bond. But with Naruto being scared, there is an added layer of unease. Naruto might avoid Sasuke, which is a big change from their usual interactions where they would confront each other directly.
Yes, there are likely to be such fanfictions. In the Naruto series, Sakura can be quite assertive and strong - willed. Her temper and skills could potentially be a source of intimidation for Naruto in the creative interpretations of fanfiction writers.
Yes, sometimes Hulk is scared of Thanos. Thanos is a very powerful and intimidating villain, and even the mighty Hulk can feel intimidated by him in certain situations.
I can't say I'm scared. They might have suspenseful moments, but that doesn't mean they scare me. It depends on the way the stories are presented and my mood at the time.
