In many 'justice league vs avengers fanfiction' stories, a really interesting scenario is when the magic - users like Doctor Strange and Zatanna face off. They have such different ways of using magic. Strange with his mystic arts from the books and Zatanna with her backwards - speaking magic. Also, the Hulk could go on a rampage against the Justice League's powerhouses like Cyborg or Martian Manhunter. This would force the heroes to work together in new and unexpected ways to stop him.
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.
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.
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.
One scenario could be Naruto using his clones to distract the Justice League while he sneaks up on Superman and uses a powerful jutsu. Another could be the Justice League trying to find Naruto's weakness, like his connection to the nine - tailed fox, and Naruto having to defend himself against their attacks. Maybe Batman tries to analyze Naruto's fighting style and come up with a plan to defeat him.
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.
One idea could be a misunderstanding that leads to a battle. Maybe a villain manipulates the situation so that Young Justice thinks the Justice League has turned evil. For example, the villain uses mind - control technology on some of the League members and Young Justice has to fight to save them.
One idea could be a misunderstanding that leads to a fight. Maybe the Justice League mistakes some of Young Justice's actions as being too reckless and end up in a battle. Then they realize they were wrong when a real threat emerges and they have to work together.
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.
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 interesting fanfiction could be where the Justice League members are magically transported to the Avengers' universe and they have to team up to fight a common enemy. For example, they might face a powerful cosmic entity that neither group could defeat alone.
A possible plot idea is that Batman discovers a dark secret within the Justice League that they are unaware of. This secret could be something that could potentially destroy the League or change their moral compass. Batman then has to decide whether to confront the League directly or try to fix the problem on his own, which causes the 'vs' situation as the League may see his actions as a threat.
