Naruto could find a hidden passage in Orochimaru's lab that leads to a secret chamber. In this chamber, there are ancient scrolls with powerful jutsu that Orochimaru was planning to use for his own gain. Naruto might decide to take these scrolls away to prevent Orochimaru from getting his hands on them again.
Imagine Naruto finding Orochimaru's lab and being trapped inside by some sort of sealing jutsu. He then has to use his wits and the skills he's learned from Jiraiya to break the seal and escape. While trapped, he discovers Orochimaru's plans to create an army of artificial ninja using the DNA of powerful shinobi. Naruto decides to destroy all the research and evidence in the lab to prevent this from ever happening.
In a fanfiction, Naruto might enter Orochimaru's lab and find a young test subject who was about to be used for one of Orochimaru's experiments. Naruto would rescue the child and then use the knowledge in the lab to try and reverse the effects of Orochimaru's previous experiments on other victims. This would show Naruto's compassionate side and his ability to turn a bad situation into a positive one.
One interesting take in a fanfiction could be that Naruto finds Orochimaru's lab while looking for Sasuke. He enters the lab full of determination to bring Sasuke back. Inside, he sees the remnants of Orochimaru's attempts to transfer his soul or create powerful hybrids. This discovery makes Naruto realize the full extent of Orochimaru's madness and the danger Sasuke is in. It also gives him more motivation to not only rescue Sasuke but also put an end to Orochimaru's evil plans once and for all.
One interesting plot idea could be a story where a young shinobi is secretly sent into Orochimaru's lab as a spy. They discover new, forbidden jutsu experiments that Orochimaru is conducting on captured ninja. Another could be about a group of Orochimaru's former test subjects who team up to destroy the lab and all its secrets. And a third idea is a story where Orochimaru's lab holds the key to curing a mysterious illness that is spreading across the ninja world.
The lab could hold secrets about Orochimaru's past. Maybe there are records of his early days as a ninja, his training, and what led him to become so obsessed with immortality. Naruto might stumble upon these records and gain a better understanding of his enemy.
Another scenario could be that Naruto discovers a hidden chamber in the lab. Inside, there are test subjects that Orochimaru was using for his immortality experiments. Naruto feels sympathy for them and tries to rescue them. However, he has to figure out how to deal with the various traps and security measures in the lab first. He might call for help from his friends like Sakura or Kakashi to assist him in this difficult task.
A character like Sasuke could be further developed in Orochimaru's lab fanfiction. He might struggle more with the dark knowledge he gains there and eventually find a way to use it for the greater good. Another character could be a new, made - up test subject who starts out as a scared victim but then becomes a strong fighter after enduring the experiments. And Kabuto, who is already associated with the lab, could have a change of heart and try to atone for his actions in the lab.
Yes, there are likely fanfictions with this concept. Fanfiction writers often come up with wild and creative ideas, and this one is quite out - of - the - box. However, in the original Naruto series, Naruto has no relation to Orochimaru in this way.
One interesting idea could be Orochimaru seeing Naruto as a unique specimen and instead of just trying to use him, he actually starts to respect Naruto's willpower. This could lead to a strange mentorship of sorts where Orochimaru teaches Naruto some of his more unorthodox jutsu in exchange for Naruto trying to help Orochimaru find a new path that doesn't involve so much darkness.
In most Naruto fanfiction, the idea of Naruto being Orochimaru's son is a very creative and out - of - the - box concept. However, in the original Naruto series, there is no such relation at all. Naruto is the son of Minato Namikaze and Kushina Uzumaki. Fanfiction writers might come up with this idea to explore different character dynamics and storylines that deviate from the canon.
Well, Orochimaru's immortality would mean that his influence would be long - lasting. He could continue to conduct his unethical experiments over a very long period. This might lead to the creation of new and dangerous ninja techniques or even new forms of life. In the long run, it could change the way ninja are trained and how the ninja world views power and knowledge. For example, some might start to see immortality as the ultimate form of power and strive for it at all costs. Naruto and his friends would have to constantly be on guard against Orochimaru's schemes.
In some fanfictions, Orochimaru might develop a sense of loyalty towards Naruto. After being around Naruto for a while, he could see Naruto as someone worthy of his loyalty. This could lead to him being more open to working with the Hidden Leaf and helping Naruto in his various missions. He might even sacrifice his own interests to protect Naruto at times, which is a complete turnaround from his initial character.
