I can't provide any information about Plants vs Zombies because I'm a fan of web novels and don't have the ability to directly access and search for web texts.
I think young Sasuke would have a very intense reaction. He was so consumed by his hatred for Itachi at that young age. A Sasuke vs Itachi fanfiction would be like a trigger for him. He would be eager to see how the fictional fight is portrayed. If Sasuke in the fanfiction is shown as strong, it might fuel his own ego and make him strive even harder to become powerful. However, if the fanfiction shows Itachi as superior, it could enrage him. He might feel that it undermines his own goal of defeating Itachi and he might even want to find the writer to correct their 'wrong' view.
One of the best stories is when Flash has to outwit Captain Cold's new ice - based weaponry. Flash uses his super - speed to create heat friction and melt the ice. It shows the classic battle of speed against cold power.
The main characters are Peter and Flash. Peter is often depicted as the underdog, a smart but sometimes shy guy. He might be a bit of an outcast in school. Flash, on the other hand, is usually the popular jock. He's cocky and likes to show off, often picking on Peter. In the fanfiction, their interactions drive the story, whether it's a friendly competition or a full - blown feud.
I like Naruto in these fanfics because he always stays true to his beliefs. He is constantly trying to bring Sasuke back to the village and is willing to fight for their friendship.
One of the best moments is when they have a rematch that showcases their growth. Naruto has become stronger with his new jutsu, and Sasuke has further mastered his Sharingan powers. The intense battle of ideologies during the fight is captivating.
One interesting plot could be a competition between Peter and Flash in a science fair. Peter uses his intelligence and some of his spider - powers subtly to create an amazing project, while Flash tries to outdo him with his over - the - top showmanship. Another plot might be a race where Peter, without using his full spider - speed, still manages to keep up with Flash who is the school's track star, leading to Flash being both frustrated and a bit in awe of Peter.
It really depends on the writer's preference. Some fanfictions might have Naruto winning because of his unwavering belief in friendship and his ability to draw on the power of the nine - tails. Others might have Sasuke winning due to his strategic mind and mastery of the sharingan.
It's not clearly stated in the original Naruto series that Konoha as a whole watches Naruto vs Sasuke fanfiction. Fanfiction is a creation of the fans outside the official story. However, it would be an interesting concept to think about. Some characters might be amused or even inspired if they were to read such fan - created stories, but there's no in - canon evidence for it.
One common theme is unrequited love. Sakura often has strong feelings for Sasuke, but Sasuke may be too focused on his own goals to fully reciprocate. Another theme is the power struggle. Since they are both powerful ninjas, their battles can represent a struggle for dominance or recognition within the ninja world.
