If combined, it could be really interesting. Maybe we'd see Harry Potter characters using lightsabers as magical extensions of their wands. Or the Jedi could learn magic spells from the wizards. The Death Star could be attacked by a combination of magic and the Force.
A combined story would be full of unique possibilities. The Hogwarts castle could be protected by a combination of magic and Star Wars - style shields. Star Wars characters might be introduced to magical creatures from Harry Potter. And imagine Darth Vader facing off against Voldemort, that would be an epic battle of two very different kinds of dark lords with their own powers and motives.
The characters can be combined by creating scenarios where they meet. For example, a magical portal could open between Hogwarts and a Star Wars planet. Then, characters like Harry Potter might be attracted to the unique qualities of characters like Princess Leia or Luke Skywalker, forming part of a harem. Or a Sith Lord could find the magic of the Harry Potter world fascinating and start to court some of the powerful witches or wizards there.
The story could be different in that Aunt Petunia might become more empathetic towards Harry. If she reads fanfiction, she might start to see different interpretations of his situation and understand him better, which could lead to a change in their relationship at home.
In the fanfiction, Padme might be a lost soul from the Star Wars universe who ends up in the Harry Potter world. She quickly adapts to the magical environment. With her strong will and determination, she becomes a mentor figure to some of the younger students at Hogwarts, teaching them about different ways of fighting for what is right, drawing from her own experiences in Star Wars.
I think Qrow could be really powerful in this crossover. He has his own unique abilities in RWBY, and if he were to also master the Force, especially the more combat - oriented aspects like telekinesis to throw his weapon with more force or use the Force to enhance his reflexes, he'd be a force to be reckoned with. He also has a lot of experience in combat which would help him adapt to the new powers.
Well, it could be as simple as using the themes of heroism from '911'. In the Star Wars universe, you can have characters show the same kind of selfless heroism as the firefighters and police officers during '911'. For example, a group of rebels might sacrifice themselves to save a planet in a similar way.
One way is to have the Star Wars characters time - travel to WW2. For example, Darth Vader could end up in a battle and his advanced technology and powers would shock the soldiers. It would be a cool scenario where the dark side of the Force meets the real - world chaos of war.
The Avengers would have diverse responses to the elements of Harry Potter fanfiction. Take the magical creatures, for example. Thor would be excited to learn about hippogriffs and dragons, perhaps seeing them as worthy opponents or interesting allies. Tony would be thinking about how to study and potentially use their unique abilities for his own inventions. Steve would be in awe of the loyalty of creatures like the house - elves, which would remind him of the importance of loyalty among his team. Natasha would be analyzing the role of the magical creatures in the power dynamics of the wizarding world, and Clint would be looking for ways to outwit them if they were threats. Bruce would be concerned about the potential harm that some of the more dangerous creatures could cause if not properly managed.
One way to combine them is by creating a crossover universe. Imagine if the magic from Garry Potter's world collided with the technology and diverse species of Star Wars. The Emperor could be a powerful dark wizard in this new universe, using both Sith powers and magic spells. Maybe he could rule over a hybrid empire of wizards and Star Wars species, using his dark arts to control both magic and the Force.
A fanfiction like this would blend elements in many ways. First, the settings would merge. Hogwarts could exist in the same universe as Metropolis or Gotham. The characters would exchange their skills. Batman could learn some magic tricks from the Potter characters. The concept of immortality could be a unifying factor. The immortals in the Potter world might have a different view on life and death compared to the superheroes. This could lead to philosophical discussions within the story, as well as new ways of approaching battles and solving problems.
Well, it might be something like this. In a frontier town on a far - flung planet similar to the Old West on Earth. There are saloons where smugglers and bounty hunters gather. Han Solo - type characters might be dealing with rustlers who are stealing valuable energy crystals instead of cattle. The light side and dark side of the Force could play out like the battle between good and bad in a typical Wild West showdown.
