Definitely a Force - sensitive child who the Sith Stalker discovers. The Sith Stalker has to decide what to do with the child - train them in the ways of the Sith or let them go. Another interesting character could be an old Sith spirit that haunts the Sith Stalker, giving them cryptic advice. And a smuggler who ends up helping the Sith Stalker on one of their quests, for a price of course.
One character could be a droid with a unique personality. Maybe it was once part of a Jedi research project and has some knowledge about the Sith. It could be both an annoyance and an asset to the Sith Stalker. There could also be a Sith Lord who is the master of the Sith Stalker but has a hidden agenda. And a street - wise pickpocket on a planet the Sith Stalker visits, who ends up being more than they seem.
Well, a plot could revolve around the Sith Stalker being sent to infiltrate a Jedi stronghold. They have to disguise themselves as a Jedi initiate. During this time, they start to form unexpected friendships with some of the Jedi. This causes a conflict within them as they are supposed to be loyal to the Sith. They must then decide whether to complete their mission or betray the Sith for their newfound friends.
Darth Maul is a great character to include. As a Sith, his menacing presence and his unique fighting style would add a lot to a Sith Pureblood fanfiction. Another one could be Count Dooku. His sophisticated and devious nature would interact well with the Sith Purebloods. And of course, General Grievous. Even though he's not a Sith, his role in the Clone Wars and his connection to the Separatists could create interesting storylines when paired with Sith Pureblood characters.
In a Dooku - centered fanfic in The Clone Wars, Qui - Gon Jinn could be an interesting addition. Even though he's dead, Dooku could be haunted by memories of his former apprentice. This could add an emotional layer to the story. Count Dooku's own family members, if any are explored in the Star Wars lore, could also be included. Their influence on his decisions, or how he thinks about them while being a Sith, could be fascinating. Also, other Sith Lords or acolytes that Dooku might interact with in the shadows during the Clone Wars would be cool to include.
The Sith Stalker Armor inquisitor is a really cool concept in Star Wars fanfic. It often represents a menacing and powerful figure. In many fanfics, the character wearing this armor is depicted as highly skilled in combat and in the ways of the Dark Side. It can add a sense of mystery and danger to the story, making the inquisitor a formidable antagonist or even an anti - hero in some cases.
One way to portray the oc sith stalker armor inquisitor is as a silent and deadly hunter. They can move stealthily in their armor, stalking their prey (which could be Jedi or other enemies). The armor can be described as enhancing their natural abilities, like giving them extra speed or strength.
Darth Maul could be a great character. His unique appearance and his thirst for power would make him an interesting addition to a Sith harem. He could be the enforcer, using his double - bladed lightsaber to protect the group.
One memorable OC Sith could be Darth Zyra. She has a very distinct look with her purple - hued lightsaber and her elaborate black and red robes. Her power lies in her ability to manipulate the minds of her enemies, which she uses to great effect during battles in the Clone Wars.
Shaak Ti. She was a powerful Jedi, but not much was explored about her in the movie. In fanfiction, you could delve into her backstory, her relationships with other Jedi, and how she might have reacted to the events of the Clone Wars and Anakin's fall. For example, she could have had a secret mission to uncover the Sith's plot that was cut short by Order 66.
Definitely include Obi - Wan Kenobi. He has a connection to Geonosis already from the movies. Anakin Skywalker would also be a great addition. And for a non - Jedi character, you could add a Geonosian rebel who is trying to overthrow the corrupt leaders on the planet.
The story of Darth Vader is perhaps the most well - known Sith story. Anakin Skywalker, once a Jedi, turned to the Dark Side after being manipulated by Palpatine. His transformation into Vader, his role in the Galactic Empire, and his ultimate redemption at the end of 'Return of the Jedi' are all iconic parts of the Star Wars saga.
