A vampire lord from the 'Star Wars meets Vampires' world could be a main character. He rules over a group of vampires and is constantly looking for ways to expand his power. When he discovers the power of the Force, he becomes determined to use it for his own dark purposes.
One interesting plot could be that a group of vampires in the Star Wars universe are using the Force to enhance their vampiric abilities. They might be able to use the Force to become invisible while they hunt for prey, which throws the Jedi and Sith into confusion as they try to figure out this new threat.
Twilight Sparkle and Luke Skywalker could be main characters. Twilight's knowledge of magic and her inquisitive nature would make her a great counterpart to Luke's Jedi training and his journey of self - discovery. They could learn from each other and face challenges together.
For the Star Wars side, it could be Luke Skywalker. He has that sense of adventure and discovery which would make him very interested in the ponies. And on the My Little Pony side, Twilight Sparkle would be a great choice. She is very intelligent and curious, much like Luke. She would be eager to learn about the Star Wars universe.
An old Clone Wars veteran, either a clone or a non - Jedi military figure, could be the main character. They have seen the destruction of Order 66 and now suspect there is more to the story with Order 67. Their knowledge of the past wars and military strategies would be useful in uncovering the truth.
The main characters could be a group of bounty hunters. They get hired to investigate the origin of Order 69, thinking it might lead to a big payday.

There could also be a Sith apprentice who is using the chaos caused by the order to rise in power within the Sith hierarchy.
Even Boba Fett could be a main character. He's used to dealing with dangerous situations. In a zombie - infested Star Wars world, he could be hired to retrieve something from a zombie - filled area. He'd use his weapons and his bounty hunter skills to survive the hordes of undead while also facing other threats in the galaxy.
They could be the children of Luke Skywalker. Maybe he had triplets in secret, and they inherit his strong connection to the Force. Each of them could have different personalities, like one being very brave and impulsive, one being more cautious and intellectual, and the other being empathetic and diplomatic.
Obviously, the apprentice themselves would be a main character. They could be a young and ambitious force - user, eager to learn from their master. The master, who is likely a powerful Sith or Jedi, depending on the nature of the fanfiction, would also be a key character. And then there could be a rival apprentice or a mentor figure from the apprentice's past that plays a significant role.
Well, aside from Master Chief, Cortana can be a popular character. Her intelligence and relationship with Master Chief can be explored in new ways when combined with Star Wars.

His bounty - hunting skills and cool demeanor would be interesting to see in the context of the Halo universe.

He represents the classic hero, and his journey from a farm boy to a Jedi Knight can be paralleled with many Earth - based hero stories. Chewbacca also has his fans.
