Well, imagine Thanos in the Star Wars universe. He could be a Sith - like figure, trying to gather all the kyber crystals (akin to the Infinity Stones). The Avengers could team up with the Jedi to stop him. The Hulk could be like a Wookiee in terms of his brute strength, and Thor's hammer could be seen as a sort of lightsaber - like weapon in the Star Wars aesthetic. There are so many possibilities for these two universes to collide in fanfiction.
One interesting crossover could be a story where the Jedi from Star Wars meet the Avengers. Maybe the Jedi could teach the Avengers about using the Force, and in return, the Avengers could show the Jedi some of their high - tech gadgets. Another could be a battle scenario where the Sith Lords team up with some of the Avengers' villains like Loki, creating a chaotic and epic showdown.
In some fanfictions, you might see Kanan Jarrus training the Avengers in lightsaber combat. Since the Avengers have different fighting styles, learning the elegant and precise art of lightsaber fighting would add a new dimension to their skills. Also, imagine Thrawn strategizing against the Avengers. His brilliant military mind would pose a great challenge to the heroes.
The characters can be incorporated by simply having them show up in the Star Wars galaxy. For example, Thor could land on Tatooine with his lightning powers, causing quite a stir among the locals. His Asgardian technology could be a mystery to the Star Wars characters.
One interesting reaction in fanfiction could be the characters dealing with the shock of losing so many comrades. For example, the remaining Avengers might struggle with survivor's guilt. Another could be the exploration of how different characters' powers interact in the face of such a massive threat. Some fanfictions might also focus on the emotional toll on characters like Thor, who has already lost so much and then faces this new catastrophe.
A really interesting plot could be based on the idea of time travel within the context of 'The Avengers Infinity Wars' fanfiction. What if the Avengers found a way to go back in time and change certain events that led to Thanos getting the Infinity Stones? They could try to prevent the destruction of Xandar where the Power Stone was first retrieved, or stop Loki from stealing the Tesseract on Earth, which was a crucial step in Thanos' plan.
The high - stakes nature of the stories. Just like in both the original Star Wars and Infinity War, the fate of the galaxy (or universes) is at stake. This makes for really intense and engaging reading. Fanfic authors often come up with creative ways to raise the stakes even further, like introducing new super - powerful villains or having the Infinity Stones corrupt some of the Star Wars characters. It keeps the readers on the edge of their seats.
One interesting crossover could be Ben using his Omnitrix to transform into an alien that has the power to use the Force. For example, he could transform into a species that has telekinetic abilities similar to Jedi powers. Another could be the Ben 10 characters getting involved in the Galactic Civil War in the Star Wars universe. Maybe they help the Rebels fight against the Empire using their unique abilities.
One interesting crossover could be Pokemon trainers in the Star Wars universe. They might use their Pokemon to help in battles against the Sith or the Empire. For example, a Pikachu could use its electric attacks to short - circuit stormtrooper weapons.
In 'Naruto and Star Wars' fanfiction, a cool crossover might be the characters' training methods. Jedi training and ninja training have some similarities and differences. The Jedi focus on the Force and lightsaber combat, while ninjas in Naruto train in various jutsu. A fanfiction could explore how a Naruto character might adapt to Jedi training or vice versa. And the different cultures could also interact. The shinobi villages in Naruto could be compared to the different planets and factions in Star Wars, creating a lot of potential storylines for crossovers.
One interesting crossover could be Spiderman getting transported to the Star Wars universe. He might use his web - slinging abilities in the zero - gravity environments of spaceships or on different planets. It would be really cool to see how he interacts with characters like Luke Skywalker or Darth Vader.
