One idea could be a story where a god - like being from another dimension enters the Star Wars universe and has to choose a side in the galactic conflict. Maybe this being has the power to manipulate the Force in ways no Jedi or Sith has ever seen before.
Another plot could be about a group of Star Wars fans who accidentally get sucked into their own fanfiction world. In this world, there is a god - like figure who is in control of the fate of the characters. They have to find a way to convince this god - like entity to send them back to their own reality while also dealing with the chaos of the Star Wars universe.
One idea could be exploring the origin of a new, mysterious force - user in the Shadow Wars. Maybe it's a forgotten Jedi or Sith technique that resurfaces and causes chaos. Another could be focusing on the relationship between a group of rebels and how they deal with the added threat of the Shadow Wars.
A great plot for Star Wars The Clone Wars fanfiction could be centered around a new, unknown planet that gets caught in the middle of the war. The planet has its own unique species and culture. The story could follow how the clone troopers and the Jedi interact with this new civilization, whether they try to protect it or use it for their own strategic advantages. Or perhaps a story where a group of clone troopers start to develop their own individual personalities and question their loyalty to the Republic due to some unethical orders they receive. This could lead to a conflict within the clone ranks and force the Jedi to take sides.
One idea could be exploring the backstory of the apprentice before they met their master. Maybe they had a family on a far - off planet that was destroyed, which led them to seek power. Another could be a story where the apprentice has to choose between loyalty to their master and doing what they believe is right. For example, if their master orders them to destroy an innocent village, they might rebel.
One idea could be that the triplets are force - sensitive and are secretly trained by an old Jedi master in hiding. They grow up to be a powerful force against the dark side.
One idea could be a story where a young Jedi discovers the Darksaber and has to resist its dark influence. Maybe they are on a mission to return it to its rightful place.
A fanfiction could explore what would happen if the Jedi had to face the power of the One Ring. The Jedi's connection to the Force might give them some resistance to the Ring's corrupting influence, but it would still be a great struggle. It could also involve characters from both universes learning from each other's cultures and ways of combat.
A cool plot idea could be that the Transformers are mistaken for a new type of Sith - created abomination. The Jedi initially try to destroy them, but then realize they are something different. Another idea is that a Transformer becomes a Jedi Knight, using its unique abilities in combat and its own code of honor which is similar to the Jedi Code.
Another plot could involve a journey across different planets in the Star Wars universe by Digimon. They could be on a quest to find a powerful artifact that can save both the Digimon world and the Star Wars galaxy from a great evil. Along the way, they meet various Star Wars species and have to overcome different challenges.
One idea could be exploring the backstories of the Separatist leaders in more detail. For example, how did Count Dooku really get involved with the Separatist movement? A fanfiction could delve deep into his motives and early days.
A great plot for Star Wars Kamino fanfiction could involve a lost Jedi Padawan who ends up on Kamino. The Padawan discovers that the Kaminoans are experimenting with a new type of clone that has Force - sensitive abilities. This discovery puts the Padawan in a difficult position as they have to decide whether to report it to the Jedi Council or try to stop the experiments on their own. Another idea is to write about a clone who starts to have memories of a previous life and realizes that he was cloned from a person with a very different moral code. He then tries to break free from the programming of the Kaminoans and find his own identity. Also, a story about a smuggler who lands on Kamino and gets caught up in the politics between the Kaminoans and the Galactic Republic could be really interesting.
