The village elders or certain hidden factions within the village could be antagonists. If Naruto turns dark because of their actions against him, they would naturally be in opposition to him as he seeks revenge or tries to change the village in a way they don't want.
One possible plotline could be that Naruto is constantly ostracized by the village, which slowly breaks his spirit and makes him turn to the dark side. He might start to use forbidden jutsus without any moral restraint.
Naruto and Gaara is another possible pairing. Gaara also has a dark past and has had his own struggles with darkness. If Naruto is giving into darkness, their shared experiences could bring them closer in a yaoi context. Gaara might understand Naruto's pain and be able to relate to his descent, and they could form a bond that has both a romantic and a mutual - understanding aspect.
One common theme could be the struggle between Naruto's light - filled past self and the new, dark - influenced self. In many yaoi fanfictions, there might be a relationship that either causes or is affected by this descent into darkness. For example, a relationship with another male character where power dynamics, jealousy, or a need for acceptance play a role in Naruto's change.
Well, one possible plot could be that Naruto, after giving into darkness, forms an unexpected alliance with the Fem Kyuubi. Maybe he sees the power she represents as a means to achieve his new, darker goals. He might start using her chakra in more sinister ways, causing chaos in the ninja world. This could lead to his friends trying to save him from this dark path, but he resists their attempts, believing his new way is the only way to truly change things.
Naruto's development would likely involve a loss of his moral compass. He would no longer hold the values he once did, such as loyalty and friendship. His relationships with his friends like Sasuke, Sakura, and Kakashi would be severely strained. They would try to reach out to him, but he would push them away. The Fem Kyuubi could develop into a more sympathetic character as she gets closer to Naruto. She might start to understand the human emotions she once scoffed at and use her new - found understanding to either further corrupt Naruto or to save him from himself. It all depends on how the author wants to play out their relationship.
In this fanfiction scenario, Naruto giving Tenten a sword could be a really interesting plot point. Maybe Naruto found a special sword during one of his adventures and thought Tenten, being a weapons expert, would appreciate it. It could lead to Tenten developing new fighting techniques with the sword, and perhaps she would use it in future battles against powerful enemies.
