Madara Uchiha is also a common opponent. Since he was such a formidable foe in the original series, fanfiction writers love to put Naruto in situations where he has to outsmart and overpower Madara in different scenarios.
Often, it's powerful villains like Orochimaru who make a comeback in fanfiction. Naruto has to use his growth and new abilities to defeat him once and for all.
It depends. Some fans might find it acceptable as it could explore different character dynamics and power relationships. They might see it as a creative take on the characters.
Well, in some of these fanfictions, Naruto might show off new and powerful jutsu that he didn't have in the original series. For example, he could combine his Rasengan with some kind of elemental power in a really cool way.
Another could be Kaguya Otsutsuki. However, in the fanfiction, she may return in a more powerful form. Maybe she has found a way to break free from the seals completely and has amassed even more power from other dimensions. Naruto, being abnormally strong, would still have a tough time fighting her as she is one of the most powerful characters in the Naruto lore.
Obviously Naruto. Since it's a 'naruto kicks sasukes ass fanfic', the title kind of gives it away that Naruto is going to be the winner.
Well, in such a fanfiction, it's likely a wild and imaginative scenario. Naruto has his own set of powerful ninja skills like the Rasengan and Shadow Clone Jutsu. The Justice League members also have their unique powers. Maybe the writer wants to explore what would happen if Naruto, from a completely different fictional universe, were to face off against the likes of Superman, Batman, and Wonder Woman. It could be a really fun read if it's well - written, exploring different combat styles and strategies.
In such a fanfiction, perhaps Naruto has been pushed too far by Sakura's constant nagging. He might finally snap and show his superior combat skills. Maybe Sakura made a wrong decision during a mission that endangered the whole team, and Naruto, in his fury, decides to teach her a lesson through a non - lethal fight.
The clash of two very different fictional universes. Naruto's ninja - based powers and the Justice League's superpowers are so distinct. It's like pitting ancient ninja arts against modern - day superhero abilities.
In the fanfic, it could start with a build - up of tension between Naruto and Sasuke. Naruto has been training hard and has reached a new level of power. Sasuke, on the other hand, might be underestimating Naruto. When they finally clash, Naruto's sheer determination and his unique Uzumaki chakra, along with his mastery over the Nine - Tails' power, allow him to dominate the fight and kick Sasuke's ass. This could also be a way for Naruto to try and bring Sasuke back to the village, by showing him that he can't always have his way and that they are stronger together.
Well, from a practical standpoint, comparing the two is like comparing apples and oranges. Their universes have different rules regarding power and physics. In a fanfic, though, the writer can manipulate the story to suit their desired outcome. Maybe Naruto uses his intelligence and strategic thinking along with his chakra powers to defeat Superman. It could be that the fanfic has Superman in a situation where his powers are nullified and Naruto is able to use his ninja skills to gain the upper hand.
Sasuke would still be a likely opponent. Even though Naruto has enhanced speed, Sasuke has his own unique abilities like the Sharingan which can predict movements to some extent. Their battles would be even more intense, with Naruto's speed against Sasuke's strategic use of his Sharingan and ninjutsu.
