Well, in fanfic the possibilities are endless. It's not unheard of for Orochimaru to be Naruto's sensei. Fanfic is a place where authors can rewrite the rules. They could have Orochimaru take Naruto under his wing for various reasons. Maybe Orochimaru sees potential in Naruto that he can use for his own ends, or perhaps it's part of a redemption arc for Orochimaru where he tries to train Naruto in a different way compared to the traditional senseis in the original series.
In some fanfics, Orochimaru can be made Naruto's sensei. Fanfic authors often like to play with the original story's elements and create unique scenarios. They might think that having Orochimaru as Naruto's sensei would lead to a very different kind of character development for Naruto, full of more moral and ethical challenges due to Orochimaru's dark nature.
Naruto might learn some very dark and powerful jutsus. Orochimaru is known for his forbidden jutsu knowledge. So Naruto could become a much more dangerous fighter but also risk being influenced by Orochimaru's immoral ways.
Well, it really depends on the specific fanfic. There are countless Naruto fanfics out there, and some might indeed have Ibiki as Naruto's sensei. This could be an interesting twist as Ibiki has his own unique skills and personality. He could teach Naruto some different things compared to the original senseis in the Naruto story, like more about interrogation techniques or mental fortitude in a different way.
One possible fanfic could be about a student of Orochimaru who rebels against his evil ways. This student, perhaps having seen the destruction Orochimaru causes, decides to use the knowledge he has gained in a positive way. He might start by secretly helping the Hidden Leaf Village, using his skills in jutsu and forbidden arts to protect rather than harm.
The student could go on an adventure to find a cure for Orochimaru's curse mark. Since Orochimaru often experiments with curse marks on his students, this one particular student might be determined to find a way to get rid of it once and for all. He could travel to different hidden villages, seeking out ancient scrolls and wise sages for answers.
Yes, there are likely fanfics with this concept. Fanfiction platforms have a wide variety of creative works. You can check popular Naruto fanfic sites like Fanfiction.net or Archive of Our Own. Just search for 'Naruto is Kushina Sensei' and you might find some interesting stories.
He could have adventures in the Forest of Death. Anko has experience there, and she could take Naruto on more dangerous and secretive missions within that area. Naruto would learn how to better handle the perils of that forest.
One possible fanfic could be about a student of Orochimaru who struggles with the dark arts they are being taught. This student might start to question Orochimaru's motives as they see the harm his experiments cause. For example, they could witness the pain of the test subjects in Orochimaru's lair and decide to rebel. They might try to find a way to use the knowledge they've gained for good, like developing healing jutsu based on Orochimaru's research on the human body.
In some fanfics, Naruto might use his new and powerful jutsu that he has mastered over time. Maybe he combines his Sage Mode with the power of the Nine - Tails in a unique way that Orochimaru can't counter. For example, he could use the Nine - Tails' chakra to enhance the range and power of his Sage Mode attacks, and then catch Orochimaru off - guard.
If Ibiki were Naruto's sensei in a fanfic, Naruto would likely gain a whole new set of skills. Ibiki is known for his interrogation and torture techniques, so Naruto could potentially learn about getting information from enemies in a more effective way. Also, Ibiki's strict and disciplined nature would probably make Naruto more responsible and less impulsive. This could change the way Naruto approaches battles and missions, as he would be thinking more strategically instead of just relying on his brute strength and the Nine - Tails' power.
In some fanfictions, it might be so. Fanfiction allows for a lot of creative and out - of - the - box interpretations. Writers often like to create unexpected family relationships to add new twists to the story. However, in the original Naruto series, there is no such relation.
