One consequence could be that his friends have to protect him while he's unconscious. They might need to fight off enemies who see Naruto's fainted state as an opportunity to attack. For example, Sakura and Sasuke would have to step up and defend him.
Naruto would likely be deeply hurt. He is a character who values friendship and loyalty highly. Being betrayed by someone he might have considered an ally like Rias would be a huge blow to his emotional state.
The consequences could be quite complex. Firstly, there's the physical aspect. He could experience intense pain during the transformation process, which might be a regular occurrence depending on the rules of the werewolf lore in this fanfiction. Emotionally, he might struggle with his identity. Is he still Naruto the ninja, or is he now something else? This internal conflict could lead to some interesting character development. Socially, his relationships might change. Some of his friends might be afraid of him, while others might be intrigued and want to help him. And from a plot perspective, this new development could lead to all sorts of adventures, like seeking a cure or finding others like him.
One possible consequence could be an immediate power boost. Since Dark Naruto represents the repressed and negative aspects of Naruto, absorbing it might give Naruto access to a new level of strength that was previously locked away. This new power could be both physical and mental, allowing him to face stronger opponents.
One consequence could be that Sakura feels rejected and this might lead to her character developing in a different way. She could become more independent or focus more on her own skills. Another consequence is that it could change the dynamic of their friendship group. If Naruto and Sakura are not interacting, it might affect how other characters interact with them too.
When Naruto achieves the Rinnegan in fanfiction, it often changes the power dynamics in the Naruto world. His newfound power might make some of his friends and allies feel a bit left behind or inferior. This could lead to some strain in his relationships. On the combat side, he could now access abilities like the Preta Path to absorb chakra attacks, which would make him extremely difficult to defeat in battle. However, this new power also comes with a greater responsibility. He may have to be more careful not to accidentally harm those around him with his more potent jutsu.
In some fanfictions, when Naruto absorbs the bijuu, he might gain overwhelming power. This could lead to him being able to easily defeat powerful enemies that were previously a threat. For example, he could single - handedly take on the Akatsuki without much difficulty.
One consequence could be that his friends start to fear and distrust him. After all, controlling people goes against the principles they uphold. They might see him as a threat and try to stop him, which could lead to a lot of conflict among them.
Well, in fanfiction, Naruto releasing chakra can have different effects. Sometimes it can cause a change in his appearance, like his eyes glowing more intensely or his body being surrounded by a more powerful aura. It might also lead to new jutsu development as he has more chakra to experiment with. And, depending on the plot of the fanfiction, it could be a sign of him reaching a new level of power, which then sets off a chain of events in the story, such as other characters reacting to his newfound strength.
One consequence could be that he becomes overly powerful. His new - found ability to absorb chakra might make him a force to be reckoned with, changing the power dynamics in the fanfiction world. Enemies may fear him more, and allies might start to rely on him even more heavily.
