One popular plot is the 'lost technology' plot. Suppose some ancient Star Wars technology is discovered during WW1. This could change the course of the war. Maybe a power source from a Star Wars ship is found and the side that discovers it tries to weaponize it. Or perhaps a Jedi artifact is found and it has some sort of magical effect on the soldiers who come in contact with it. There could also be a plot where a Star Wars character is reincarnated during WW1 and has to rediscover their powers and purpose in this new and very different world.
A common plot is the time - travel plot. A Star Wars character travels back in time to WW1. For example, Darth Vader could end up in the trenches of WW1 and his presence causes chaos as his powers are so out of place. Another plot is the parallel universe plot where there is a universe where Star Wars and WW1 are combined from the start. In this universe, lightsabers are used in the trenches and Jedi are leading the troops.
Survival is also a big theme. In both Star Wars and WW2, characters are constantly facing life - threatening situations. In fanfiction, this can be explored by having characters from one universe adapt to the survival challenges of the other. For example, a Star Wars character trying to survive in the harsh conditions of a WW2 battlefield. It can show how their skills and abilities are tested in a new and difficult environment.
Another plot could be Azula getting stranded in the Star Wars universe and having to adapt. She might team up with some unlikely allies, like a group of smugglers. As she tries to find a way back to her own world, she gets involved in various inter - galactic conflicts. This plot often involves her using her wits and combat skills to survive and thrive in this strange new universe.
A common plot in Revan - Star Wars fanfiction is his time as a Sith. Writers often delve into his motives and how he rose to power. Some fanfictions also involve his return to the Jedi Order and the challenges he faces in being accepted again. Additionally, there are plots where Revan discovers new aspects of the Force during his adventures, which could change the balance of power in the galaxy.
One idea is to have a Jedi Council - like group in WW2. They could be made up of different leaders from the Allied and Axis sides who come together to find a more peaceful solution to the war. They would use their wisdom and leadership skills, similar to how the Jedi use the Force, to try and end the bloodshed.
One challenge is maintaining the essence of both universes. Star Wars has its own set of rules regarding the Force, technology, and species, while WW2 has a historical context that needs to be respected. It's difficult to blend these two distinct elements without sacrificing the integrity of either.
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 to blend them could be by imagining the Clone Wars' military strategies in the context of WW2. For example, the large - scale battles and use of different units in Star Wars could be compared to the Allied and Axis forces in WW2. Maybe the clones could be seen as a highly - trained military force like the special units in WW2. Another aspect could be the political intrigue. In both, there are complex power plays and political maneuverings that could be explored in fanfiction.
Some fanfictions might have a plot where Obi - Wan's daughter has a special mission related to her father. For example, she discovers that Obi - Wan left behind a powerful Jedi artifact that only she can retrieve. She has to face many challenges, including dark side users who also want the artifact. This journey not only tests her physical and mental strength but also her connection to the Force and her understanding of her father's legacy.
One popular plot could be a scenario where they share a kiss during a moment of victory. After a tough battle against the Empire, with the adrenaline still high and the relief of survival, they might look at each other and share a spontaneous kiss. It could be a sign of their deepening bond and mutual respect for each other's skills in combat and as friends.
One popular trope is the 'Force - Bond' where two characters, often a Jedi and another, are connected through the Force in a special way. Another is the 'Hidden Jedi' trope, where a character discovers they have Jedi abilities later in life. 'Time - Travel' is also quite common, with characters going back or forward in time in the Star Wars universe.
