Naruto could be like a new and unique member. His ability to use ninjutsu would be a fresh addition. And the Juubi could be a power source or a danger they have to deal with. Maybe Naruto uses his skills to help the Justice League understand the Juubi better.
Well, in this fanfiction, the Juubi might be seen as a new kind of threat or a potential ally in the Justice League world. Naruto, being a skilled ninja, could bridge the gap between the two different universes. He could introduce the concept of chakra to the Justice League members. For example, Superman might be intrigued by how Naruto can use chakra to enhance his physical abilities and try to learn something from it. The Juubi's massive power could also be a factor that either unites or divides the characters in the story.
The crossover would likely involve a lot of cultural clashes too. Naruto comes from a world of ninjas and feudal - like structures, while the Justice League is from a more modern, superhero - dominated world. This could lead to some comical moments, like Naruto trying to figure out how to use a cell phone or the JL members being confused by Naruto's headband. But when it comes to the Juubi, they'd have to put aside their differences. The Juubi's power might be so great that it could potentially destroy both universes. So Naruto and the Justice League would need to combine their powers, with Naruto using his chakra - based attacks and the JL members using their superpowers like Superman's heat vision, Green Lantern's constructs, etc., to take on this ultimate threat.
The Juubi could be the main villain or a major threat that brings Naruto and the Justice League together. Its massive power would be a huge concern for both parties.
One possible plot could be that Naruto, with his Juubi - like powers, somehow gets transported to the DC universe. He meets the Justice League and at first, there are misunderstandings. The League might see him as a threat because of his immense power. But then, they realize he's there to help when a common enemy, perhaps a powerful interdimensional villain, emerges. Naruto teams up with Superman, for example, and they use their combined strength and abilities to fight the foe.
Well, Naruto himself would be very curious about the Justice League. He would probably be excited to meet heroes with such different powers. He might try to show off his own skills a bit at first. As for the League, Superman would likely be intrigued by Naruto's chakra - based powers. He would want to understand how they work compared to his own superpowers.
Yes, there might be. You can try searching on fanfiction websites like Archive of Our Own or FanFiction.net. There are a large number of fan - created works out there, and with the popularity of Naruto and the Justice League, it's quite possible that someone has combined the two in a 'godlike' way in their fanfiction.
Maybe Naruto's character essence is so different from the Justice League that he seems out of place in that fanfiction context. His ninja world values and his own story arc are unique to his universe, and being mashed into Justice League fanfic just doesn't feel right to some people, and perhaps that's how the idea of 'Naruto hates Justice League fanfiction' comes about.
Naruto would fit in by being the energetic and determined member. His loud and boisterous personality would contrast with some of the more reserved members of the Justice League. His physical abilities, like his superhuman strength and speed gained from his ninja training, would make him a valuable addition in battles.
In this fanfiction, Naruto might use his ninja skills. His shadow clone jutsu could be a great asset. He could send clones to gather information about the threat the Justice League is facing. Then, with his Rasengan, he could directly attack powerful enemies. Also, Naruto's ability to endure and keep fighting could inspire the Justice League members when they are in a tough situation.
