In a Dragon Ball Z - Star Wars fanfiction, the Dragon Balls could be a huge plot point in the Star Wars universe. What if the Rebels were searching for the Dragon Balls to wish for the destruction of the Death Star? And Darth Vader could be after the Dragon Balls as well to wish for unlimited power or to bring back Padmé. This would lead to a race between the two sides and some amazing confrontations.
Well, in some fanfictions, characters like Darth Vader and Goku could have epic battles. Imagine Vader trying to use the Force against Goku's super strength and speed. Also, the idea of Saiyans being part of the Star Wars universe, perhaps as a powerful and feared race among the different species in that galaxy far, far away. They could bring their own brand of combat and power - up techniques to the Star Wars setting.
One interesting crossover could be Goku meeting Luke Skywalker. Goku's raw power and his Saiyan abilities would contrast with Luke's connection to the Force. Maybe they could have a friendly sparring match where Goku shows off his Kamehameha and Luke uses his lightsaber skills. Another idea is Vegeta facing Darth Vader. Their pride and determination would make for an intense encounter, with Vegeta's Galick Gun against Vader's Force choke or lightsaber attacks.
One great 'Star Wars Dragon Ball Z Fanfiction' is 'The Galactic Saiyan'. It combines the epic space battles of Star Wars with the super - powered fights of Dragon Ball Z in a really cool way. The author does a great job of making the characters from both universes interact in a believable manner.
One interesting crossover could be Goku meeting Elsa. Goku might be intrigued by Elsa's ice powers and try to spar with her. He could learn a lot about controlling power from Elsa as she has to constantly keep her emotions in check to avoid causing too much ice mayhem, much like how Goku has to control his Saiyan rage.
A really cool crossover concept could be the sharing of techniques. Spiderman could learn how to use Ki blasts from Goku or Vegeta. In return, he could teach them some of his acrobatic fighting moves. This exchange of skills would create some really unique and exciting battle scenes in the fanfiction, as they combine their different fighting styles to take on common enemies.
In some fanfictions, Goku could team up with Ash. Goku's super strength and ability to fly would be a great asset. He could help Ash in battles against tough opponents like Team Rocket when they use more powerful Pokemon or machinery. Also, Goku might be intrigued by the concept of Pokemon evolution, which is somewhat similar to Saiyan power-ups.
One popular crossover could be a battle between Natsu from 'Fairy Tail' and Goku from 'Dragon Ball Z'. They both have incredible strength and unique fighting styles. Another might involve the characters teaming up to face a common enemy that threatens both of their worlds. It could be interesting to see how Natsu's fire - based magic interacts with Goku's ki - based attacks.
Well, a great aspect of crossovers in their fanfiction could be the battles. Imagine Goku from Dragon Ball Z facing off against Vilgax from Ben 10. Goku's martial arts skills and ki blasts against Vilgax's brute strength and advanced weaponry. And what if Ben, in his alien forms, had to team up with Goku to fight a common enemy? That would make for an exciting story.
First, you need to have a solid understanding of both universes. Know the characters, their powers, and the rules of each world. For example, in Dragon Ball Z, the concept of power levels and transformations is crucial, while in Star Wars, the Force and different species' cultures matter. Then, come up with an original plot that can blend these two worlds together in an interesting way.
One interesting crossover could be a battle between Hulk's brute strength and Goku's Super Saiyan power. Maybe in the fanfic, they start off as rivals, with Hulk misunderstanding Goku as a threat to Earth. Their fight would be epic, with Hulk's limitless rage against Goku's increasing power levels. It could also explore how their different universes' power systems interact.
