Noble Six could be a lost soldier from another galaxy who ends up in the Star Wars galaxy. Maybe they get involved with the Rebel Alliance and use their military training to help in the fight against the Empire. For example, they could teach some of the Rebel soldiers new combat tactics. They might also have some advanced technology from their own world that could be useful in the Star Wars setting.
One way could be to make Noble Six a new type of bounty hunter in the Star Wars universe. They could have unique combat skills and armor that would set them apart from other characters.
Noble Six could be a smuggler. They would use their skills to navigate dangerous routes and outwit the Empire's patrols, much like Han Solo. Their backstory could be that they were once a part of a military unit but turned to smuggling after some events in their past.
Perhaps Gohan could be a bounty hunter in the Star Wars fanfiction. He'd use his combat expertise to track down the toughest targets. His Saiyan tail could be a unique feature that other characters in the Star Wars universe find strange. He could get involved in the underworld of the galaxy, facing off against smugglers and criminals while also having run - ins with the Jedi and Sith.
In a RWBY fanfiction, the Delta Squad could be on a mission to retrieve a valuable relic that has somehow ended up in the RWBY world. Their presence then sets off a chain of events as they interact with teams RWBY, JNPR, etc. They might initially be seen as a threat, but as the story progresses, they form alliances and work together towards common goals.
Anakin could be part of a time - travel story in a fanfiction. What if a character from Star Wars Rebels was sent back in time and met Anakin before his fall? They could try to change the course of his future, which would have a huge impact on the events of Star Wars Rebels and the entire galaxy.
Naruto's Rasengan could be seen as a new kind of energy attack in the Star Wars universe. It could be as powerful as a lightsaber strike or a blaster bolt. Maybe only those with strong Force abilities can withstand it or deflect it, like how some Sith Lords can block Jedi attacks.
She could be a sort of anomaly in the Star Wars universe. Scarlet Witch's powers are so distinct. In fanfiction, she might be a key to unlocking some ancient and forgotten power related to the Force. For example, her ability to manipulate probability could be translated into affecting the will of the Force in unexpected ways. She could be a catalyst for change in the power balance between the light and dark sides.
You could also make the Transformers a part of the backstory in Star Wars fanfiction. Suppose there was an ancient race that created both the Transformers and the precursors to the Star Wars technology. This connection could explain some of the similarities in advanced machinery between the two universes. For instance, the idea of self - aware droids in Star Wars could be related to the sentience of the Transformers.
One way is to have Sonic as a unique alien species in the Star Wars universe. Maybe he's a super - fast courier on a planet like Tatooine, using his speed to outrun the local gangs or deliver important messages.
Well, if we think about it, the Force in Star Wars has some similarities to the magic in The Neverending Story. So, characters like Yoda could potentially be in The Neverending Story as a wise mentor figure. He could teach the characters in that world about the power within them, just like he does with the Jedi. And perhaps Darth Vader could be a menacing presence, his dark side clashing with the more light - hearted elements of The Neverending Story.
He could be a Force - ghost. His spectral form could guide Kanan or Ezra at crucial moments. For example, when they face a difficult decision regarding the Dark Side, Mace Windu's Force - ghost could appear and offer his wisdom based on his own experiences with the Sith.
