Well, in 'justice league vs avengers fanfiction', there might be a scenario where Superman and Thor have a power - clash. Superman's heat vision against Thor's lightning could be an epic showdown. Then there could be a situation where the Green Lantern and Hawkeye have a long - distance battle, with the Green Lantern creating constructs to block Hawkeye's arrows. And what about Aquaman and Namor teaming up or fighting against each other? That would add a lot of depth to the story.
Batman and Iron Man are likely to form an alliance. They both rely on their intelligence and technology. They might see the value in working together against a common threat. Another possible alliance could be between Wonder Woman and Captain America. They both have strong moral compasses and a sense of honor, so they could team up easily.
Well, a cool plot could be time - travel related. Say a device sends members of the Avengers back in time to the DC universe and they accidentally disrupt something that makes the Justice League think they're invaders. Or perhaps there's a villain who has the power to manipulate minds on a large scale and he turns the two teams against each other. Also, a plot where the two teams have to compete in a series of challenges set by an ancient being for some great reward, but the challenges are designed to make them fight each other.
It's hard to say for sure, but Superman could be a top contender. His super strength, speed, and flight, along with his heat vision and other abilities, make him extremely powerful. He can withstand a lot of damage and dish it out just as well.
One idea could be that a powerful cosmic entity forces them to fight. It creates an artificial situation where they believe the other group is a threat to the universe. For example, it manipulates their perceptions so the Avengers think the Justice League is stealing powerful artifacts to control the multiverse, and vice versa.
Definitely Hulk vs Superman. Hulk's raw strength and his ability to get stronger as he gets angrier against Superman's near - invincible strength and speed would be a great match - up. Also, Iron Man vs Batman. You have the high - tech genius of Iron Man going up against the strategic and detective skills of Batman. Another interesting one would be Thor vs Wonder Woman. Thor with his godly powers and his hammer against Wonder Woman with her Amazonian strength and her own magical weapons.
Another possibility is a post - Endgame fanfiction. After the events of Endgame, the Avengers discover a new threat that has ties to the Justice League's world. Maybe a powerful villain from the DC universe has somehow been awakened by the events in the Marvel universe. So they have to reach out to the Justice League for help and together they figure out a way to stop this new threat.
Yes, there are many good ones. You can find them on fanfiction websites. Some focus on epic crossovers between the Justice League and the Avengers, with amazing battles and team - ups.
In a 'naruto vs justice league fanfiction', the outcome depends on many factors. If Naruto can quickly take out key members like Batman with his surprise attacks, he might have an edge.

Also, Naruto's chakra limitations could be a problem against the seemingly limitless powers of some Justice League members.
