Well, if Ahsoka Tano were a Sith Apprentice in a fanfic, she would likely be in a constant struggle between the dark side's allure and her inherent good nature. She might have some really cool and menacing Sith powers, like lightning that has a unique blue - white color due to her Togruta heritage. Maybe she would be in a situation where she has to face her former Jedi friends, leading to some very intense battles and emotional confrontations.
She would become more cynical. The Sith Apprentice Ahsoka would start to see the galaxy in a different light. No longer believing in the Jedi ideals of peace and justice, she would view power as the ultimate goal. Her once - friendly demeanor would turn cold, and she would be more calculating in her actions.
She could be developed through her interactions with Sith apprentices. Maybe she tries to redeem one of them, showing her compassion and strong will. This would also show her growth from her Jedi training.
One great Sith Ahsoka fanfic is 'The Dark Path of Ahsoka'. It explores an alternate universe where Ahsoka turns to the Sith side. The story is filled with intense battles and moral dilemmas as she struggles with her new identity.
The setting of the fanfic is important too. If it's set in a new part of the Star Wars universe, it should be described vividly. For a Sith Ahsoka, perhaps it's a dark and desolate planet where she trains in the Sith arts. The descriptions of her using Sith powers, like lightning or mind control, should be exciting and not just a rehash of what we've already seen in the movies. Also, the fanfic should have some sort of conflict, not just internal conflict within Ahsoka but also external, like a fight against the Jedi or other Sith who oppose her new - found power.
Another theme could be redemption. In many Ahsoka Sith fanfic, even if she dips into the dark side, there is often a path towards redemption. It shows that no matter how far one falls, there is always a chance to come back. This can be a very powerful and inspiring theme, as it gives hope to the characters and the readers alike. Also, the exploration of power is a theme. The Sith are known for their pursuit of power, and when Ahsoka gets involved with them, she may be tempted by the promise of greater power, which can lead to many different plot developments.
I'd recommend 'Sith Apprentice: Legacy of the Dark Side'. It's a story that focuses on an apprentice who discovers an ancient Sith artifact and the chaos that ensues. It's full of mystery and action.
One idea could be that she is influenced by a powerful Sith artifact. Maybe she discovers an ancient Sith holocron that slowly corrupts her mind, making her question her Jedi teachings. This could lead to her making small compromises in her beliefs until she gradually slips towards the dark side.
Ahsoka as a Sith would have a different fighting style. She would be more aggressive and use more Sith - inspired powers. Her lightsabers might even change in appearance, perhaps taking on a more menacing red glow. She would also start to form alliances with other Sith or dark - side characters, which would change the power dynamics in the galaxy.
One unique aspect is how the characters from Naruto adapt to the Sith apprentice role. For example, a character like Sasuke might be more inclined to embrace the Sith teachings due to his own dark past, but Naruto would have a harder time. This creates a lot of interesting character development and conflict.
