In a small town, there lived a good guy, Lily. She was a teacher. A bad guy, Mr. Dark, who was a drug dealer, was trying to corrupt the local youth. Lily noticed his activities. She gathered evidence secretly. Then, she bravely confronted Mr. Dark in front of the whole town. The townspeople supported her. They helped to arrest Mr. Dark, and Lily continued to educate the children to stay away from bad things.
In a straight - up fight, Itachi has some very powerful abilities. His genjutsu can be extremely difficult to break out of, and his ninjutsu attacks are strong. But Batman is no slouch. He has fought against some of the most powerful villains in the DC universe. He would study Itachi's moves and try to find a pattern. Batman might also use his wealth to create some sort of countermeasure to Itachi's Sharingan. Overall, it's a very close call and would likely depend on how the writer of the fanfiction wants the story to go.
One interesting scenario could be a battle in a dark, abandoned cityscape. Itachi's Sharingan abilities would give him an edge in terms of perception and illusions. Batman, on the other hand, would rely on his gadgets and combat skills. He might use smoke bombs to disrupt Itachi's line of sight and then try to get in close with his martial arts. Another scenario could be a mental battle. Itachi is used to psychological warfare, but Batman is also a master of getting into his opponents' heads. Itachi might try to use his genjutsu to break Batman's will, but Batman's strong mental discipline could resist it.
One interesting scenario could be a battle of wits. Itachi is known for his intelligence and Sakura has grown to be a very smart and capable ninja. They might engage in a mental duel where they try to outmaneuver each other with strategic moves and mind games.
One common theme is justice. The good guy is usually fighting for what is right and fair, like in a story where a detective (the good guy) chases a criminal (the bad guy) to make sure the law is upheld. Another theme is sacrifice. Sometimes the good guy has to give up something to defeat the bad guy, for example, a hero leaving his family to go on a dangerous journey to stop an evil force. Also, redemption can be a theme. Maybe the bad guy has a chance to change in the story, but often they don't take it and the good guy has to force the situation to a conclusion.
In most traditional interpretations, Itachi would be favored to win due to his long - established reputation as a powerful and feared ninja. But in the realm of fanfiction, the writer can tip the scales in Sakura's favor. For example, if Sakura has mastered some sort of anti - Sharingan technique or has a power - up that nullifies Itachi's main abilities, she could emerge victorious.
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.
In certain 'guy vs naruto fanfiction', the guy could be a magic user from a world without ninjas. His magic might work in a completely different way compared to Naruto's chakra - based powers. For example, he could use elemental magic that is not the same as Naruto's use of the five elements. Their fight would be a clash of two different power systems. Also, the guy might have a different moral code that affects how he fights Naruto. He could be more ruthless or more cautious, depending on his background, which adds another layer of complexity to the story.
The theme of courage is very common. The little guy in the story has to be extremely brave to stand up to the giant person. It's like David and Goliath. David was just a small shepherd boy, but he had the courage to face the giant Goliath. Another theme is the idea of growth. Through the encounter with the giant, the little guy might grow in strength, wisdom or character. And sometimes, the theme of friendship or alliance can also be seen. The little guy may find allies to help him against the giant.
