A powerful Nightsister could be a great OC. The Nightsisters have their own connection to the dark side of the Force. An OC Nightsister could use her magic and knowledge of the dark side to interact with Anakin. She might offer him new ways to use the Force, like some of the unique spells and abilities that Nightsisters possess.
One possible plotline could be the OC's influence on Anakin's fall to the dark side. Maybe the OC has a unique view on the Force that starts to sway Anakin's beliefs. For example, they could introduce him to a more extreme interpretation of the power that the dark side offers.
One great Dark Anakin fanfiction could be about his internal struggle. It might show how the dark side slowly creeps in as he faces difficult decisions in the Clone Wars. For example, a story could focus on a mission where he's tempted to use excessive force to achieve victory, and how that starts to change his mindset towards the dark side.
One common theme is redemption. Since Anakin's story in the official Star Wars lore is about his fall and redemption, many fanfictions with OCs explore this further. The OC might be the catalyst for Anakin's redemption or be involved in his journey in some way.
Some fanfictions may focus on the emotional turmoil that leads Anakin to the dark side during The Clone Wars. His fear of losing Padmé, his ambition to be a great Jedi, and his growing disillusionment with the Jedi Council all play a part. By exploring these emotions in depth, we can see how he becomes more susceptible to the dark side's allure.
Sure. 'The Force of an Unlikely Bond' is a great one. It shows how Anakin interacts with an original character in a really interesting way.

One interesting Dark Anakin fanfiction could be one where he fully embraces the dark side earlier than in the movies and tries to reshape the galaxy according to his own vision. He might form new alliances with Sith Lords from the past.
The SI could also be a love interest for Anakin. In a fanfiction, this could be a very different kind of relationship compared to what he had with Padmé.
