In alternate Star Wars fanfiction, a really cool concept is the idea of different Force abilities. Instead of the traditional Jedi mind tricks and Sith lightning, there could be new powers. For instance, some fanfictions might explore a Force ability that allows a character to communicate with droids on a deeper level. There are also concepts where certain planets have different levels of importance. Maybe Tatooine is a high - tech planet instead of a desolate desert world. And of course, there are alternate love stories. What if Luke Skywalker fell in love with a Sith instead of a Rebel?
One interesting concept could be alternate endings for major battles. For example, what if the Rebels lost at Endor? It would completely change the galaxy's power structure. Another concept might be different character backstories. Maybe Darth Vader had a different master before Palpatine. And there could also be fanfictions exploring an alternate universe where the Jedi and Sith have different rules or abilities.
Well, in alternate Star Wars fanfiction, there are often concepts like different species ruling the galaxy instead of humans. Imagine a universe where the Wookiees were the dominant political force. Also, some fanfictions play with time travel concepts within the Star Wars universe. A character might go back in time to prevent Anakin from turning to the dark side. And then there are those that focus on a different alignment of the Force, like a more neutral Force that doesn't have the clear cut Jedi and Sith divide.
