One idea could be creating an OC who is a lost Jedi from an ancient order. They could have unique Force powers that were long forgotten. Another is an OC who is a smuggler with a heart of gold, getting involved in the Rebel Alliance's affairs by accident.
One idea could be about an OC (Original Character) in the corps who discovers a long - lost Jedi artifact. This discovery could lead to a race against the Sith to obtain it. Another plot could involve an OC with unique Force - related abilities in the corps trying to unite different factions within the Star Wars universe to fight a common enemy like the Yuuzhan Vong. Or perhaps an OC in the corps uncovers a conspiracy within the military ranks that threatens the stability of the galaxy.
One idea could be creating an OC who is a Jedi with a unique lightsaber form that combines different traditional forms in unexpected ways. For example, a form that mixes Ataru's acrobatics with Makashi's precision. Another idea is an OC bounty hunter who has a moral code that often puts them at odds with other bounty hunters in the Clone Wars universe. They might refuse certain jobs that involve excessive violence or harm to innocents. Also, an OC clone trooper with a special talent like being an amazing artist, using the limited resources on the battlefield to create art that gives hope and a sense of normalcy to his fellow troopers.
One idea could be to have the Ninjago characters travel to the Star Wars universe. For example, Lloyd could meet Luke Skywalker and learn about the Force from him. Another idea is to combine the weapons and powers. The Ninjago weapons like the Golden Weapons could have some sort of interaction with lightsabers.
A redeemed bounty hunter could be an interesting concept. They take on a job that turns out to be for an evil cause. Feeling guilty, they turn against the employer and start working towards redemption by helping those the employer had targeted, all while dodging other bounty hunters who still follow the code of the hunt.
A 'Star Wars crossovers fanfic' might involve a crossover with the Marvel universe. For instance, the Jedi could team up with the Avengers. Luke Skywalker and Captain America could lead their respective teams in a battle against a common enemy. It would be really exciting to see lightsabers and superpowers in one story.
One idea could be a crossover where the Dragonborn from Skyrim somehow ends up in the Star Wars universe. Maybe they use their Thu'um powers in the midst of a lightsaber battle, creating a really unique combat scenario. Another idea is that Sith or Jedi could be transported to Skyrim and have to deal with the dragons and the political unrest there. They might try to use the Force to tame the dragons or influence the different factions.
Maybe a sitcom about a group of Rebel Alliance soldiers stationed on a remote base. They have to cope with the boredom between missions, so they start doing things like holding their own 'Star Wars Olympics' with events like pod - racing simulations and lightsaber - handling challenges. And there's always that one soldier who's overly obsessed with Ewok culture and tries to incorporate it into their daily life.
One interesting idea could be the reincarnation of a Jedi into a new era. They might bring back forgotten Jedi teachings and skills. For example, a reincarnated Jedi could have memories of ancient lightsaber forms and use them in new battles against the Sith or other threats.
One idea could be focusing on a young clone trooper who discovers he has unique Force abilities. He then has to hide this from his superiors while trying to figure out what it means.
Another interesting angle would be to have a Clone Wars character, like Anakin Skywalker, land on Earth for some reason. His presence could cause a stir among the people, and his Jedi powers would be both fascinating and potentially terrifying to the Earth population.
