One possible plot could be that Naruto uses his'real' henge to infiltrate a powerful enemy organization undetected. He could assume the identity of one of their top members and gather crucial intelligence.
One interesting plot could be a female character using the henge to infiltrate an all - male ninja group. She might have to keep up the act while facing various challenges and also dealing with her own feelings of being in a male - dominated environment. Another plot could involve a female ninja using henge to transform into a powerful male figure from history to gain respect and learn certain skills that are only passed down among men in the Naruto world.
Yes, in some Naruto fanfiction, the idea of Naruto's henge being real in a different or extended sense could be explored. Writers might play with the concept, for example, making a henge that is so perfect it fools even advanced ninja senses and becomes a key plot point in the story.
One possible plot could be that Naruto accidentally uses a new type of henge that makes him disappear not just visually but also from the ninja world's chakra detection. His friends then go on a quest to find him. They might face various challenges and encounter old enemies who are taking advantage of Naruto's disappearance. In the end, they find a way to reverse the henge and bring Naruto back.
One possible consequence could be that his identity is revealed. If he was using the henge for undercover purposes or to hide his true self, then dropping it would expose him. His friends or allies might be shocked if they didn't know his true form. Another consequence could be that his enemies might take advantage of his revealed state and attack him more easily, as they now know exactly who he is.
Well, a plot twist could be that the henge was initially a joke by Naruto, but then it becomes permanent due to some dark magic or curse. Kurama, who has always been Naruto's ally, now has to find a way to break the curse. Maybe the breast transformation attracts the attention of a powerful and previously unknown enemy who wants to use Naruto for some evil purpose. This would completely change the direction of the fanfiction from a comical story to a more serious adventure. Also, it could be that the transformation is a test from the Sage of Six Paths, and Naruto has to pass it in order to gain new levels of power, which Kurama is initially skeptical about.
A possible plot could be that Vash's world and Naruto's world start to merge. Naruto meets Vash during this chaotic time. Vash is initially skeptical of Naruto's ninja ways which seem so violent compared to his own. However, as they work together to save both of their worlds from destruction, they come to understand and respect each other. Naruto, inspired by Vash's selfless nature, starts to change his approach to fighting, and this causes a stir in his own ninja community as they are not used to such a pacifist - like Naruto.
It could be that Naruto sacrifices himself to seal away a great evil. However, his friends don't believe he's truly gone and embark on a journey filled with self - discovery and growth as they try to find a way to bring him back. Along the way, they might encounter other lost souls or forgotten powers that could potentially help in their quest.
One idea could be Naruto using the Henge no Jutsu in creative ways during a mission. For example, he could transform into a famous ninja from the past to deceive the enemy. Another idea is that Naruto accidentally henges into a different form that has unexpected powers.
One possible plot could be that Naruto sacrifices himself to save the village from a powerful and ancient evil. He uses all his chakra in a last - ditch effort to seal away the threat forever, leaving the village in mourning but also in a state of safety. Another plot might involve Naruto being poisoned by an enemy who has infiltrated the village. Despite the efforts of Sakura and the others, they can't find a cure in time, and Naruto succumbs to the poison. A third idea could be that in a battle against a new, incredibly strong foe, Naruto is overpowered and killed, which then spurs the rest of the shinobi world to come together to avenge his death.
One possible fanfiction idea could be Naruto using his henge technique to transform into someone wearing a really cool swimsuit. Maybe he does it for a mission at a beach resort where he has to blend in with the tourists. He could transform into a famous surfer and use his skills to gather information.
