Maybe in this fanfiction, Naruto is kidnapped at birth by a rogue ninja who wants to raise him as his own to create a powerful successor. This ninja takes Naruto to a far - off land where he is taught different ninja techniques. Eventually, Naruto discovers the truth about his abduction and decides to return to Konoha to reunite with his true family and friends.
One possible plot could be that a powerful and secret organization kidnaps Naruto at birth to use his special chakra for their own dark purposes. They keep him hidden away, training him to be a weapon against the Hidden Leaf Village. However, as Naruto grows, he starts to question his captors' motives and tries to break free to find out about his true heritage.
In this 'naruto kidnapped at birth fanfiction', it could be that an enemy village kidnaps Naruto. They believe that by having the son of the Fourth Hokage, they can gain an advantage over the Leaf Village. Naruto is raised in a hostile environment, but he still has his kind heart. As he gets older, he manages to escape and goes on a journey to understand both his new - found enemies and his original home, leading to a complex story of identity and loyalty.
It could be Orochimaru. He is always on the lookout for powerful specimens to experiment on or train in his ways. Naruto, as the son of the Fourth Hokage, would be an extremely appealing target for him at birth.
If Naruto was kidnapped by Orochimaru at birth, the entire Naruto universe would be drastically different. Konoha would lose its Jinchuriki, which could lead to a power imbalance. Without Naruto, the Nine - Tailed Fox's power couldn't be harnessed for the village's protection. Also, Orochimaru might have used Naruto's Uzumaki heritage and the power of the Nine - Tails for his own dark experiments. This could have led to the creation of more powerful and dangerous entities. His Akatsuki plans might also be affected as Naruto was a key part of their overall scheme.
Perhaps Sasuke has been influenced by some dark force. This force could be manipulating him into believing that Naruto is a threat to his goals. So, he kidnaps Naruto to either stop him from interfering or to convert him to his side. It could lead to a very intense struggle within Naruto to resist Sasuke's influence.
The story could start with Naruto being lured into a trap set by Kiri. Once kidnapped, he finds himself in a prison cell deep within Kiri's territory. The Kiri ninjas might try to interrogate him about Konoha's secrets or his own unique abilities. Naruto, being Naruto, refuses to cooperate. As time passes, he befriends a fellow captive who has some knowledge about Kiri's inner workings. With this new ally, Naruto formulates a plan to break free. Meanwhile, Konoha's search party is facing many obstacles in their attempt to find Naruto in the unfamiliar and dangerous land of Kiri.
One possible plot could be that Sasuke has a hidden agenda. Maybe he believes Naruto is in danger from a new, unseen enemy in the ninja world. So, instead of explaining his reasons to Naruto, he kidnaps him to keep him safe in a secret location. However, this action might be misinterpreted by their friends, leading to a search and rescue mission.
One possible plot could be that Naruto is found by a group of outcasts. They decide to raise him away from the Hidden Leaf Village. As he grows, he discovers his own unique powers that are different from the normal ninja skills in the village. He then has to decide whether to return to the village that abandoned him or create his own path with his new family.
One possibility could be that Naruto is kidnapped by a hidden enemy right at birth. Maybe a rogue ninja group has a vendetta against the Fourth Hokage and they steal Naruto away. This would lead to a completely different story arc in the Naruto universe, with Konoha perhaps not knowing Naruto's true identity and not treating him as the Jinchuriki. It could also mean that Naruto grows up in a different environment, away from the discrimination he faced in the original story, but also without the friends and support system he eventually had in Konoha.
It could be that Kumo has a rogue group within their village that wants to use Naruto for their own malicious purposes. They kidnap him in the chaos of a diplomatic visit or something similar. Once kidnapped, Naruto finds himself in a difficult situation as he is far from home. But he uses his never - give - up attitude and starts making friends with some sympathetic Kumo ninjas who help him in his fight against the rogues and eventually his escape back to Konoha.
Another plot development could be that Madara actually wants to turn Naruto to his side. He might believe that Naruto, with his strong will and powerful chakra, could be a great asset. So, during the kidnapping, he tries to convince Naruto of his so - called 'righteous' cause, perhaps by showing Naruto some 'truths' about the ninja world that Naruto was previously unaware of.
Well, perhaps Danzo kidnaps Naruto because he sees Naruto as a threat to his secretive and often unethical operations. He might fear that Naruto will eventually expose his wrongdoings. So, he takes Naruto to a hidden location and tries to keep him there, but Naruto's friends like Sasuke and Sakura would then start a rescue mission.
