What could be the plot in a 'Justice League Marvel crossover fanfiction'?

The plot could start with Vegeta being exiled from his own planet due to some political intrigue. He ends up on Earth, where he crosses paths with the Justice League. At first, there is tension as the League is unsure of his intentions. But when a powerful enemy, like Darkseid, starts to target Earth, Vegeta decides to help. He teams up with Superman, and they have an epic battle of strength. Meanwhile, Batman uses his detective skills to figure out a weakness in the enemy's plan. Wonder Woman, Aquaman, and Flash also play their parts, with Vegeta adding his Saiyan speed and power to the mix. In the end, they defeat the enemy, and Vegeta decides to stay on Earth for a while to learn more about these strange heroes.

One possible plot could be that the Hulk is somehow transported to the DC universe and is initially seen as a threat by the Justice League. They might try to subdue him, but then realize he's not entirely a villain. Maybe there's a common enemy that forces them to team up. For example, a powerful alien force that is causing destruction in both the Marvel and DC universes. The Hulk's brute strength combined with the Justice League's diverse powers could make for an epic battle against this enemy.

One possible plot could be that the Omnitrix malfunctions and sends Ben 10 to the Justice League's universe. The Justice League initially views Ben as a threat due to his alien forms. But as they learn more about him and the threat of an inter - dimensional villain, they team up. Ben's different alien forms offer unique skills that complement the League's powers, and together they fight the villain to save both universes.

One possibility could be that the Jedi and the members of the Justice League team up to fight a common enemy. For example, a powerful Sith Lord who has somehow made his way to the DC Universe and is causing chaos. The Jedi's use of the Force combined with the superpowers of the Justice League members like Superman's strength, Batman's strategic mind, and Wonder Woman's combat skills would make for an epic battle.

A cool plot could be that the Justice League discovers a strange energy signature that turns out to be Iron Man's arc reactor. They track it down and find Iron Man. Iron Man is initially out of his depth in this new world of superpowers. But he uses his wits and technology. For example, he could upgrade the Flash's suit to make him even faster, and in return, the Flash helps him understand the new world he's in. Together, they all face off against Darkseid who has plans to invade both universes.

One possible plot could be that in the future setting of Batman Beyond, an old threat from the Justice League's past resurfaces. Terry McGinnis as Batman Beyond teams up with the original Justice League members who have come out of retirement. They have to combine their old - school heroics with Terry's high - tech gadgets to defeat the villain.

Well, perhaps the plot starts with a group of villains from both universes teaming up. The Power Rangers are in over their heads as these villains are using a combination of magic and advanced technology. The Justice League, on the other hand, is also struggling as their usual tactics don't work. The Rangers reach out to the League through some interdimensional communication device. They then meet up and combine their forces. For example, Wonder Woman and the Pink Ranger could lead the charge in combat, while the Flash and the Red Ranger use their speed to disrupt the villains' plans. Eventually, they defeat the villains and each group learns something new about teamwork from the other.

A plot could involve Goku being summoned to the DC Universe by a powerful magic user who believes Goku can help stop an impending apocalypse. The Justice League is skeptical of this strange, powerful being from another world. However, as they face challenges together, they start to trust Goku. For example, when they are up against a horde of powerful demons, Goku's speed and strength are crucial. He could teach some of the League members about ki control, and in turn, they could teach him about teamwork in a more strategic sense compared to his usual battles on Earth.

One possible plot could be that Naruto is somehow transported to the DC Universe. He teams up with the Justice League to stop an evil force that is using a combination of Naruto - style ninjutsu and advanced technology from the DC world. For example, Lex Luthor could be the mastermind behind this, having found a way to harness chakra and is using it to create powerful and dangerous weapons. Naruto's skills in combat and his ability to sense and manipulate chakra would be a great asset to the Justice League, and in return, the League could teach Naruto about their powers and technology.

Well, perhaps in this fanfiction, Naruto's godlike status makes him a target for the villains in the Justice League's universe. The Justice League members, initially skeptical of Naruto, start to respect him as they see him use his chakra powers in creative ways to combat the villains. For example, Naruto could use his shadow clone jutsu to outnumber enemies like Lex Luthor's robotic army. They could then team up to face an even greater threat that requires both Naruto's ninja skills and the superpowers of the Justice League.
