What could be an interesting plot for a Star Wars and Avengers crossover fanfiction?

One possible plot could be that a group of gladiators from the Spartacus era are somehow transported to the Star Wars universe. Maybe they end up on a planet like Tatooine. The gladiators' combat skills would be highly valued in the Star Wars underworld. They could get involved in the local power struggles, perhaps siding with the Rebels against the Empire as they are used to fighting for freedom in their own time.

One possible plot could be that Naruto and his friends are somehow transported to the Star Wars universe. Naruto, with his strong sense of justice, might join the Jedi Order. He could use his chakra abilities in combination with the Force. For example, his Shadow Clone Jutsu could be used to create distractions during battles against the Sith. His rasengan could be powered up with the Force for more destructive power.

Perhaps the Empire in Star Wars discovers the existence of Quirks and decides to capture the MHA characters to use their powers for their own evil purposes. The students from U.A. High then have to fight their way out, with the help of some rebel forces in the Star Wars universe. They could also introduce the concept of Quirks to the Star Wars world, which would cause a big stir among the different factions.

Another concept is that a new threat emerges that requires both the skills of the Avengers and the powers of the Star Wars characters. This new enemy could be a powerful being that can manipulate time and space. The Avengers' superhuman abilities combined with the Jedi's connection to the Force would be needed to defeat it. Black Widow could use her espionage skills to gather intelligence within the Star Wars universe, while Spider - Man (if he's part of the Avengers in this fanfic) could use his agility to navigate the complex terrains of different Star Wars planets.

One possible plot could be that Delta Squad gets sent on a mission to a planet that has a long - forgotten Jedi temple. They encounter a group of Force - sensitive beings who are being hunted by the Empire. Delta Squad has to protect them and figure out how to use the ancient Jedi knowledge in the temple to their advantage.

Well, a cool plot could involve the Rebels finding the Omnitrix. Maybe Ezra discovers it and accidentally activates it, transforming into different Ben 10 aliens. This would be a huge advantage for the Rebels but also a bit of a problem as they try to figure out how to control the transformations. And Ben could show up trying to get his Omnitrix back, but then decides to stay and help the Rebels fight the Empire.

One idea could be that Percy Jackson and his friends find themselves in the Star Wars universe. Maybe they land on a planet similar to one in the Star Wars galaxy and have to team up with Jedi or Sith (though the Percy crew would be more likely to side with the Jedi). Percy's water - controlling abilities could be used in unique ways, like manipulating the water - based substances on some planets. They could also face off against creatures from both universes, like Percy fighting a rancor with his sword and powers.

A possible plot could be that a group of Autobots and some Star Wars characters are on a quest. They need to find a powerful artifact that can save both Cybertron and the Star Wars galaxy. Along the way, they face various challenges. The Autobots' combat skills and the unique abilities of the Star Wars characters like the ability to fly starships or use lightsabers combine to overcome these obstacles. They also learn from each other's cultures and values.

One possible plot could be that Master Chief somehow gets transported to the Star Wars Rebels universe. He teams up with the rebels to fight against the Empire. His advanced armor and combat skills would be a great asset. Maybe he has to face off against Imperial Inquisitors and uses his Spartan training to outwit them.

In a Star Wars Indiana Jones crossover, Indiana could be exploring an archaeological site in the Middle East when he accidentally activates a portal that transports him to a planet in the Star Wars universe, like Tatooine. There, he meets Luke Skywalker who is on a quest to find an ancient Jedi text. Indiana, being an expert in finding and deciphering ancient texts, helps Luke. And in return, Luke helps Indiana find a way back to Earth while also protecting him from the various threats on Tatooine, like Tusken Raiders and the Empire.
