One way to blend the two universes could be through time travel. In a fanfiction, perhaps a character from Back to the Future accidentally travels to the Star Wars galaxy. They could introduce advanced Earth technology to the Star Wars characters, like the hoverboard, which might be used in lightsaber battles for added mobility. This would create a whole new dynamic in the Star Wars universe.
The concept of family, which is strong in both Back to the Future and Star Wars, could be a central theme. In a fanfiction, Marty McFly could be related to a character in the Star Wars universe in some way. This connection could bring about a story where Marty has to use his skills from his own universe to help his newfound family in the Star Wars galaxy, all while dealing with the different cultures and threats present there.
Perhaps a spell gone wrong in the Harry Potter universe could open a portal to the Back to the Future universe. Hermione, being the brilliant witch she is, could team up with Marty McFly. They would have to learn about each other's worlds quickly. Hermione could teach Marty about magic, and Marty could show Hermione how to use the flux capacitor. Together, they could face challenges in both universes, like stopping Biff from taking over Hill Valley in the Back to the Future world and defeating Death Eaters in the Harry Potter world.
One way to blend them is through character crossovers. For example, imagine Naruto characters having the Force. Naruto could be a Jedi with his strong willpower and determination being similar to the Jedi way. His shadow clones could be used in unique combat situations against Sith Lords. Another aspect could be the settings. Konoha village could be like a planet in the Star Wars universe, with its own political intrigue and power struggles, just like the various planets in Star Wars.
In a Star Wars fanfic with Superman, perhaps he could be a long - lost Jedi from a different galaxy. His Kryptonian biology gives him an edge similar to the Force. His heat vision could be like a more powerful version of a lightsaber beam. He could team up with Luke Skywalker, and they could learn from each other. Luke could teach him about the ways of the Force, and Superman could show Luke new ways of using his powers in combat.
The Force in Star Wars and the Isu (the ancient, advanced race in Assassin's Creed) could be related. Maybe the Isu were an ancient civilization in the Star Wars galaxy long ago, and they had a form of the Force. Their technology could have been based on their understanding of this power. This would blend the two mythologies as it would connect the high - tech world of Assassin's Creed with the space - opera setting of Star Wars.
In Naruto in Overwatch fanfiction, the concept of elemental jutsu can be really interesting. Naruto's fire - style jutsu could be related to some of the fire - using heroes in Overwatch like Ashe. His water - style jutsu could be used in a creative way, like for defense or to put out fires in the Overwatch maps. And the idea of chakra could be something new to the Overwatch universe. It could be a power source that some characters start to tap into, leading to new abilities and power - ups.
One way to blend Star Wars and WW1 in fanfiction is through the use of similar themes. For example, the concept of a large - scale war with different factions vying for power can be explored. In Star Wars, you have the Empire and the Rebellion, much like the different sides in WW1. Another aspect could be the character development. You could take a Star Wars character and put them in a WW1 - like scenario, forcing them to adapt to new forms of combat and moral dilemmas. For instance, a Jedi might have to deal with the horrors of trench warfare while still trying to uphold their Jedi code.
One way is by giving them a common goal. For example, if there is a threat that endangers both the Star Wars galaxy and the Mass Effect galaxy, characters from both sides could team up. A Jedi and a Spectre could lead a joint mission to stop this threat.
One way to blend the Batman and Pokemon universes in fanfiction could be by having Batman encounter Pokemon in Gotham. Maybe some villain has found a way to bring Pokemon into his world and is using them for evil deeds. Batman would then have to figure out the nature of these strange creatures while also dealing with the chaos they cause.
Well, you can start by having the settings interact. For instance, the forest in 'Into the Woods' could connect to the forested areas around Forks in 'Twilight'. The characters' traits can also be combined. The vampires' elegance and strength in 'Twilight' could be paired with the cunning of some 'Into the Woods' characters like the fox. Also, the magical elements from 'Into the Woods' like spells and wishes could influence the events in the 'Twilight' universe.
One way to blend the two universes could be through character crossovers. For example, imagine a Pokemon trainer like Ash in the world of Westeros. He could use his Pokemon to help in battles or in diplomatic situations. His Pikachu's electric attacks could be used as a weapon or a deterrent in the political power plays of the Seven Kingdoms. Another aspect could be the introduction of Pokemon into the Game of Thrones ecosystem. Maybe some Pokemon could be native to certain regions of Westeros, like ice - type Pokemon in the North. This would add a new layer of complexity to the already rich lore of Game of Thrones.
