He could also be a figure from the past whose legend starts to resurface during the Clone Wars. His teachings or artifacts could be discovered, and different factions would vie for control of them. The Jedi might see his influence as a dangerous threat to the balance of the Force, while the Sith could try to use it to their advantage. This would create a whole new dynamic in the Clone Wars as both sides deal with the implications of Revan's existence.
Darth Nox could affect the Clone Wars by using his Sith powers to sway key battles. For instance, he might use Force lightning to disrupt clone trooper formations or use mind tricks on important military leaders to make them make bad decisions.
Well, a really good fanfiction is 'Darth Vader: Clone Wars Origins'. It gives a unique perspective on how Vader's character might have developed during the Clone Wars. It has some great action scenes and explores his relationship with other key characters like Palpatine. Another one to check out is 'Vader in the Clone Wars: The Untold Story'. This fanfic fills in some gaps in the official story and shows Vader's influence on the events of the Clone Wars in a different light. And then there's 'Clone Wars: Vader's Redemption', which takes a more speculative approach to Vader's character and his potential for change during the Clone Wars.
One of the most fascinating things is seeing Sidious's manipulation tactics in more detail. Fanfics often show the intricacies of how he plays different factions against each other. His relationship with Vader is also a rich area. Some fanfics might explore what Sidious really thought of Vader, was he just a tool or did he have some deeper feelings? And then there's the aspect of his connection to the dark side. Fanfics can take us deeper into his understanding and use of the dark side's power.
Power and the dark side are also frequently explored. Since Darth Talon is a Sith, fanfictions might show her struggles, growth, or her interactions with other dark side characters during The Clone Wars. They could also delve into how she might have influenced the events of The Clone Wars in ways not shown in the official canon.
These fan fictions expand the universe by exploring Vader's character in a different context. For example, we get to see his relationship with other characters like Palpatine or the clones during the Clone Wars, which gives more depth to the power dynamics in the Star Wars galaxy.
I really like 'Darth Sidious: Unveiled'. In this fanfic, we get to see Sidious from a different perspective, exploring his inner thoughts and motives more in - depth. It's fascinating to see how his thirst for power shaped his actions. Also, 'Sidious in the Shadows' is good as it focuses on his shadowy influence over different events in the Star Wars universe. There's also 'The Sidious Chronicles' which chronicles his rise to ultimate power.
One popular theme is Vader's struggle with his identity. During the Clone Wars, he was still Anakin Skywalker in many ways, so fanfictions often explore his internal conflict. Another theme is his relationship with the Jedi. Since he was on the verge of becoming a Sith, how he interacted with the Jedi during the Clone Wars is an interesting area. And power - his thirst for power and how it grew during the Clone Wars is also a common theme.
One interesting storyline could be Darth Revan being somehow resurrected during The Clone Wars and influencing the events. He might try to manipulate both the Separatists and the Republic for his own dark purposes. For example, he could use his knowledge of the Force and his strategic genius to create chaos on the battlefield, all while secretly building his own power base.
