In Star Wars and Dragon Ball Z fanfiction, there are often crossovers that explore different power systems. For example, the concept of the Dragon Balls in the Star Wars universe. What if the Jedi or Sith were to seek the Dragon Balls for their own desires? It could lead to a whole new set of adventures and power struggles. Also, the idea of characters like Piccolo teaching some of his techniques to Force - sensitive individuals in the Star Wars universe, or vice versa, Jedi teaching the Dragon Ball Z characters about the ways of the Force.
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.
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.
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 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.
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.
In Naruto x Dragon Ball Z fanfiction, a really cool concept is the sharing of training methods. Naruto could learn about the gravity training that Goku does on Planet Namek. This would significantly boost his physical strength and speed. On the other hand, Goku might be interested in Naruto's chakra control training, which could potentially help him with his ki control in a different way. And when it comes to storylines, some fanfictions might involve the search for the Dragon Balls in the Naruto world, with Naruto and his friends joining Goku and his crew to find them, leading to all sorts of adventures and battles along the way.
In Steven Universe and Dragon Ball Z fanfiction, there could be epic battles. Picture Steven and the Crystal Gems teaming up with Goku and his friends against a common enemy. The different fighting styles would make for an exciting story. Also, the concept of fusion in both series could be explored further. What if a character from Steven Universe fused with a Dragon Ball Z character? It would create a whole new and powerful being with a blend of their unique traits.
Some crossovers might involve the Dragon Balls being used in the Harry Potter universe. Maybe the wizards would be very interested in the power of the Dragon Balls to grant wishes. For example, Dumbledore could be intrigued by their potential and try to study them. Or Harry Potter himself could accidentally find a Dragon Ball and have to figure out what it is while also dealing with Voldemort. It would be a wild mix of two very different magical worlds.
In some fanfictions, Vegeta might team up with Batman. Vegeta's combat skills and Batman's strategic mind would make for a great combination. They could work together to take on a powerful villain that threatens both the Dragon Ball Z and DC Universe. For example, a villain who has the ability to steal energy like Cell and the mind - controlling powers of Brainiac.
