Well, in a fanfiction where Rey turns to the Dark Side, she could be lured by the promise of ultimate power. The Dark Side might offer her a way to rewrite the galaxy according to her own vision. She may start to manipulate and deceive those around her, like Kylo Ren once did. She could form alliances with other dark - side characters or create her own dark minions. It would be a huge shift from her original role as a hero, and would likely shock and dismay her former allies.
In a fanfiction scenario where Rey turns to the Dark Side, it could start with her being corrupted by a powerful dark - side artifact or a Sith Lord's influence. She might begin to question the Jedi teachings she once adhered to. Her transformation could lead to a new power struggle in the galaxy. The First Order might see her as an opportunity to finally crush the Resistance. She would lose her innocence and become a symbol of fear. Her relationships with characters like Finn and Poe would be completely shattered, and she would be on a path of self - destruction and chaos.
If Rey turns to the Dark Side in fanfiction, one possibility is that she becomes a powerful and feared Sith. She might use her newfound dark powers to seek revenge on those who she believes have wronged her in the past. Maybe she would target the Resistance, seeing them as the ones who failed to fully understand or support her. Her connection to the Force could take a dark turn, with her using it for domination rather than protection.
The consequences would be huge. The Resistance would lose one of its most powerful allies. It would also mean a new threat to the galaxy. Rey's turn to the Dark Side could inspire others to follow her, leading to a resurgence of the Sith. The balance of the Force would be severely disrupted.
Another plot could involve a powerful Sith Lord who manipulates Luke. The Sith Lord could use Luke's insecurities, like his fear of not being strong enough to protect his friends. He could be tricked into believing that the Dark Side would give him the power he needs, and slowly turn to the dark side as a result.
She could be driven by a sense of betrayal. Maybe she discovers that the Jedi Order has been hiding something crucial from her, like a dark secret about her past or a false promise they made. This could shatter her trust in the light side and make her vulnerable to the temptations of the Dark Side.
Kylo Ren could still be the main antagonist even if Rey turns to the dark side. He might see her as a threat to his own power within the dark side hierarchy. Maybe he wants to keep her in check or even destroy her to maintain his dominance.
A plot twist could be that Rey has a dark heritage she was unaware of. When she discovers this, she feels a pull towards the Dark Side. She may struggle with this newfound knowledge at first, but eventually give in. In the story, her transition to the Dark Side could cause chaos in the Star Wars universe. The Resistance would be shocked and some might try to bring her back. However, the Dark Side could give her new powers and a different perspective on the Force. She could then start to reshape the Sith ideology, creating a new form of the Dark Side that is more in line with her own beliefs, leading to a whole new conflict in the galaxy.
It could be a new Sith Lord created specifically for the fanfiction. This new character could be more powerful and devious than any before. He could be the one who lures Luke to the Dark Side and then becomes his enemy as they compete for power within the Dark Side hierarchy.
It could be Darth Sidious. He is always looking for powerful allies. If he senses Ahsoka's potential and her growing disillusionment with the Jedi, he might manipulate her into joining the Dark Side. His cunning and power would make him a formidable antagonist in this scenario.
One idea could be Rey being lured to the dark side by a powerful Sith artifact. Maybe she discovers an ancient Sith holocron that shows her a version of the galaxy where the dark side rules supreme and she starts to believe that it's the only way to bring true order. Another plot could involve Rey being manipulated by a dark side user who preys on her insecurities about her past and her power.
One possible plotline could be Rey being influenced by a powerful dark side artifact. Maybe she discovers an ancient Sith relic that slowly corrupts her mind and turns her to the dark side. She starts to have different views on power and the Force, believing that the ends justify the means.
Maybe the sister is a hidden Jedi. She and Rey meet by chance and then they team up to find an ancient Jedi artifact that could save the galaxy from a new threat. They face off against various enemies, including some Sith cultists.
