Madara could be experimenting on Naruto to understand the concept of the 'will of fire' that Naruto embodies. Madara has his own views on power and the ninja world, and Naruto's unwavering belief in the will of fire might be something he wants to dissect. He may think that by understanding what makes Naruto so strong in terms of his beliefs, he can either break that strength or use it to manipulate others. Also, Naruto is seen as a symbol of hope in the ninja world, and Madara might want to turn that symbol into something that represents his own ideals through these experiments.
Naruto could also use his chakra to resist. Since he has the Nine - Tails' chakra at his disposal, he might be able to disrupt the experiments. For example, he could flare up his chakra in a way that makes it difficult for Madara to continue with the procedures. Additionally, Naruto has learned various ninja techniques over the years, and he could potentially use them to counteract the effects of the experiments, like using shadow clones to create distractions or using rasengan - like attacks to break free from any devices used in the experiments.
Naruto might become more withdrawn. The experiments could make him feel like an outcast, especially if they change his appearance or abilities in a way that makes others fear him. He may lose some of his initial optimism and become more cynical.
One possible plot development could be Naruto developing new and unexpected powers as a result of the experiments. For example, he might gain the ability to use some of Madara's unique jutsu in a different way. Another could be Naruto's friends trying to rescue him and in the process learning more about Madara's true motives and the nature of the experiments. Maybe Naruto also has to struggle with his own identity as he is changed by the experiments.
Not really. While there are all kinds of themes in Naruto fanfiction, this isn't one that pops up all the time. Most fanfictions tend to focus on things like Naruto's relationships, his growth as a ninja, or his adventures. Experimentation on Naruto isn't as widespread a theme, but it does exist in some more creative and out - of - the - box fanfictions.
Well, 'naruto experimented on fanfiction' might suggest that within the realm of fan - created stories about Naruto, there are plots where Naruto is the subject of some kind of experimentation. This could be physical experimentation, perhaps related to his ninja abilities, or it could be more of a social or psychological experiment where his character is put in unusual circumstances to see how he'd react. For example, a fanfiction might have Naruto being experimented on by an enemy to try and extract the secret of his chakra power, or he could be part of an experiment within his own village to improve his combat skills in a new and untested way.
Madara could also save Naruto by using his knowledge of the ninja world. Maybe he has some inside information about a plot against Naruto and he intervenes in time to stop it. He might have discovered a secret plan by an enemy group and takes action to keep Naruto out of harm's way. This could involve manipulating events behind the scenes or directly confronting the threat.
He would probably be very angry. Naruto has always been a free - spirited person, and being experimented on against his will would be a huge violation of his rights. He might initially try to resist physically, but as the situation gets more complex, he could start to plot his escape and revenge.
He probably resists. Naruto has always been a fighter. He would not just sit there and let them experiment on him without a fight. He might use his basic ninja skills like substitution jutsu to try and escape the experimenters.
Naruto could develop a new sense of determination. He might be determined to not let Orochimaru's experiments define him. Instead, he could use what has happened as a motivation to become stronger in his own way. He may also start to study more about the type of experiments Orochimaru was doing, not to replicate them, but to find ways to counter any future threats related to that kind of science.
