Yes, in some fanfics, Naruto can be depicted as one of Orochimaru's experiments. Fanfic writers often like to explore unique and alternative storylines. They might imagine Orochimaru getting his hands on Naruto for various reasons, like to study the power of the Nine - Tails within him or to try and create a more powerful soldier. However, this is completely different from the original Naruto storyline.
In a fanfic where Naruto is one of Orochimaru's experiments, it could completely change the trajectory of his life. First, his training under Jiraiya might be affected. Jiraiya might be more cautious or even hesitant to train him further. Naruto's own view of himself would also change. He might question his identity and purpose more deeply. His powers could be a mix of his original abilities and the modifications made by Orochimaru. This could lead to some really interesting battles where Naruto has to learn to control these new powers while still holding onto his values. And his interactions with the other characters, like Sasuke and Sakura, would be very different. Sasuke might see him as a more direct threat, and Sakura might be more worried about his well - being.
One possible plotline could be Naruto being captured by Orochimaru and forced to endure various genetic experiments. Maybe Orochimaru is trying to extract the power of the Nine - Tails from Naruto in a more invasive way. Another could be that Naruto's friends, like Sasuke and Sakura, attempt a daring rescue mission while Naruto is in Orochimaru's clutches and they face off against Orochimaru's minions.
One possible scenario could be Naruto exploring new jutsu by experimenting on his own chakra. Maybe he tries to combine different elemental chakra within himself in unorthodox ways to create a super powerful and unique jutsu. Another could be related to his physical endurance. He might experiment with training methods that push his body to the limit, like enduring extreme pain or fasting for long periods while still trying to perform at his best in combat simulations.
Well, the experiments might initially make Naruto question his own identity. He might wonder if he's still the same Naruto after all the changes Orochimaru has made to him. But in the long run, it could lead to a more mature Naruto. He might start to view his power and purpose in a new light. He could become more self - reliant, not just relying on the Nine - Tails' power but also on his own newfound abilities from the experiments, and use them for the greater good.
They might use special equipment. For example, to study a Fire - type Pokemon's heat output, they could use heat - sensors. They also may set up controlled environments. If they want to study a Flying - type Pokemon's flight patterns, they would create a large, enclosed space with different wind conditions.
In this kind of fanfiction, Naruto might be subjected to various extreme experiments. For example, he could be experimented on with strange chakra - related substances to enhance or mutate his existing powers. Maybe they try to infuse him with some apocalyptic - like energy to see how his body and ninja abilities adapt.
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.
The fanfic's experiments might also introduce new and exciting plotlines. For example, Twilight's experiments could accidentally create some sort of magical chaos that she then has to fix. This could lead to her interacting with other characters in different ways, perhaps forming new alliances or resolving old conflicts as she tries to deal with the consequences of her experiments.
Some experiments could involve the diet of Pokemon in a real - life context. What do they eat? How does their diet affect their growth and power? For example, a Grass - type Pokemon might be studied to see if it can survive solely on plants found in the real world. And there could be an experiment on the breeding of Pokemon in a more realistic environment, exploring factors like genetics and compatibility.
