What could be an interesting plot for a 'Ben 10 x Justice League' fanfic?

One possible plot could be a threat that is too big for either the Justice League or the X - Men to handle alone. So they have to team up. Maybe a powerful cosmic entity is threatening to destroy both the mutant and non - mutant worlds. The heroes from both groups would need to combine their powers and strategies. For example, Superman's strength and flight could be paired with Wolverine's combat skills and healing factor. Batman's intellect could work with Professor X's telepathy to come up with a battle plan.

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.

Definitely Ben and Batman. Batman would be intrigued by Ben's Omnitrix and his ability to transform into different aliens. He would try to analyze it while Ben would be in awe of Batman's detective skills and gadgets. It would be a clash of two very different mindsets - one a young, impulsive hero and the other a brooding, strategic one.

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.

One possible plot could be that Percy Jackson's world is suddenly invaded by a powerful threat that the demigods alone can't handle. So, Percy and his friends seek the help of the Justice League. The League initially doubts the existence of Greek gods and demigods but soon realizes the seriousness of the situation. They team up, with Percy teaching the heroes about the magic and monsters of his world while they teach him about modern combat and technology. Together, they fight the new threat that combines both magic and advanced weaponry.

Well, it could be about Naruto being transported to the DC universe and teaming up with Wonder Woman and the Justice League. Maybe they face a common enemy that requires Naruto's unique ninja skills and the League's superpowers.

Perhaps Trunks is initially mistaken for a threat by the Justice League. But as they learn more about him and his mission to protect his own timeline, they start to work together. For example, Trunks could share his knowledge of advanced Saiyan fighting techniques with Batman, who then uses this knowledge to develop new strategies for the team. Meanwhile, Wonder Woman could teach Trunks about the different cultures and values in the Justice League's world.

One idea could be a tournament where the Z - fighters from Dbz and the Justice League members compete. For example, Goku could be paired against Superman in a friendly yet intense battle to see who is stronger in terms of physical strength and combat skills. Another plot could involve a common enemy that forces the two groups to team up. Maybe Darkseid and Frieza form an alliance and the combined forces of the Dbz characters and the Justice League have to stop them.

Well, it could be about the Pokemon joining forces with the Justice League to fight a common enemy. Maybe a powerful villain is threatening both the Pokemon world and the cities protected by the Justice League. The Pokemon could use their unique abilities like Pikachu's electricity or Charizard's fire-breathing in combination with the superpowers of the Justice League members such as Superman's strength or Batman's gadgets.

The plot might involve Spiderman's scientific knowledge impressing Batman. He could work with Cyborg to create some new tech to combat a threat. And his quick - witted banter would add a new dynamic to the usually serious Justice League. For example, he might crack jokes during a battle, which at first annoys the others but later they come to appreciate it as a way to ease the tension.
