Discovering a hidden power within himself. In the Naruto universe, characters often unlock new powers in times of great distress. Naruto could potentially find a new power or ability that allows him to overpower his captors and free himself from the enslavement.
By making alliances. Naruto is known for his ability to make friends. Even in captivity, he could befriend some of the weaker captors or slaves around him and together they could plan an escape and break free from the enslavement.
He could use his ninja skills. Naruto is a highly skilled ninja. He might find a moment of weakness in his captors' defenses and use his combat abilities, like his Rasengan or Shadow Clone Jutsu, to break free.
One possible motive could be power. If Naruto has some unique abilities or is a key to something powerful in the fanfic world, the kidnappers might want to control him to gain that power for themselves.
Sure, you can find Naruto enslavement fanfics. However, their popularity and writing styles differ. Some might focus more on character development, while others might emphasize the plot.
One way could be through the power of his friends. Their memories and the bonds he has with them might be strong enough to break through. For example, Sasuke's presence could stir something in Naruto, making him question the false beliefs Danzo has implanted in his mind.
One major ethical issue is the violation of the basic values of the Naruto world. Naruto is all about equality and respect among ninjas. 'Enslavement' goes against that. It also can be seen as promoting an inhumane and unjust power dynamic.
Well, it could be a secret organization that has been operating in the shadows. They might have some ulterior motive related to Naruto's power or his connection to the Nine - Tails. Maybe they believe that by kidnapping Naruto, they can control the Nine - Tails and use it for their own purposes. Another option is a jealous ninja from within Konoha. This ninja might feel overshadowed by Naruto's achievements and popularity and decides to kidnap him to get him out of the picture. Also, a powerful and ancient being awakened from a long slumber could be the kidnapper. They see Naruto as a source of energy or a key to something they desire.
It could be Orochimaru. He has always been interested in Naruto's power and potential. He might kidnap Naruto to try and extract the Nine - Tails' chakra or study his unique Uzumaki bloodline further. Another possibility is a group of rogue ninjas who want to sell Naruto to the highest bidder, thinking his value as a Jinchuriki would make them rich.
He might also get help from his friends. For instance, Sasuke could sense that something is wrong with Naruto. With his Sharingan, Sasuke might be able to see through the henge and then use his own powers to help Naruto break free. Or Sakura could use her medical ninjutsu knowledge to somehow counter the effects of the henge on Naruto.
I'm not really into the 'enslavement' concept in fanfics as it can be a bit dark and often goes against the positive spirit of the original Naruto series. However, you can try searching on some popular Naruto fanfic platforms like Fanfiction.net or Archive of Our Own. Just be cautious as such themes might not be for everyone.
Well, Naruto could start by gathering like - minded people. Maybe those who also felt left out or had a special bond with him. He could use his skills and charisma to attract them. For example, he could find others who were also orphans or had unique powers like his. Then, he would need to establish a set of rules and values for the clan, something that would be based on his own beliefs such as loyalty, hard work, and never giving up.
Naruto would likely be very angry at first. He is a free - spirited person who values his freedom greatly. So being enslaved would go against everything he stands for. He'd probably try to break free immediately, using his brute strength and any ninja techniques he can muster.
