One consequence could be that Naruto has some strange side - effects. Since Orochimaru's methods are often unorthodox, Naruto might have trouble controlling his chakra properly. For example, his chakra could be tainted with some of Orochimaru's dark chakra, making his jutsu less stable.
Well, in some fanfictions, Orochimaru might use some forbidden jutsu. He could have combined his knowledge of resurrection techniques with some unique chakra sources. Maybe he found a way to reverse the death process by using the power of the snakes he has a connection with. For example, he could have used the regenerative abilities of the snakes' chakra to bring Naruto back to life.
When Orochimaru escapes in Naruto fanfiction, it often sets off a chain of events. His escape might inspire other villains to be more bold. Moreover, it can cause chaos in the world of ninjas. Younger ninjas may be sent on dangerous missions to track him down. And his escape could also mean that he has access to more forbidden knowledge, which he can use to further his own goals, whether it's immortality or world domination.
In fanfiction, if Orochimaru is Sakura's father, it might change her relationships with other characters. For example, her friends like Naruto and Sasuke might view her differently. Naruto might be more cautious around her, fearing she has Orochimaru's evil tendencies. And Sasuke might have a more complex relationship with her, given his history with Orochimaru.
His friends would be very confused and probably worried. They know Orochimaru as a dangerous and untrustworthy person. So, if Naruto starts acting like him, they might think something is seriously wrong with Naruto. For example, Sasuke, who has his own history with Orochimaru, would be extremely suspicious and might even turn against Naruto for a while.
One possible scenario in such a fanfiction could be that Kushina's revival has a profound impact on Naruto. She could help him understand more about his Uzumaki heritage and perhaps teach him some long - lost Uzumaki jutsus. Her presence might also change the political situation in the Hidden Leaf, as she was an important figure before her death.
Since Orochimaru had many experiments and secrets, his death at Naruto's hands in the Chunin Exams fanfiction could lead to a scramble for his research. Other villages or even some rogue ninjas might try to steal his notes and facilities. In Konoha, Naruto might be pressured to reveal what he knew about Orochimaru's plans and secrets. This could put him in a difficult position as he may not know everything. Also, Sasuke, who had a connection with Orochimaru, might have a complex reaction. He could be angry at Naruto for killing Orochimaru, or he could see it as a sign of Naruto's strength and be motivated to become stronger himself.
The overall theme of the fanfiction could change. If Naruto absorbs Orochimaru, the story could start to explore themes like the nature of power and corruption more deeply. It might also delve into how Naruto can use Orochimaru's power for good, rather than succumbing to the evil associated with it. This could make the fanfiction more of a moral exploration within the Naruto universe.
One consequence could be a shift in the power balance in the ninja world. With Orochimaru gone, his followers might scatter or try to seek revenge. This could lead to new conflicts.
Well, Naruto might gain a lot of power quickly. Orochimaru has a vast knowledge of jutsu and forbidden techniques. However, he would be in constant danger. Orochimaru could be using Naruto as a pawn for his own goals, like taking over Naruto's body. Also, the power Naruto gets might be unstable or come with a price, like draining his life force over time.
One consequence could be a shift in the power balance among the ninja villages. Since Orochimaru was a powerful and feared figure, his death might cause some chaos as his former allies or subordinates try to either avenge him or claim his resources. For example, some of his secret labs and experiments might be up for grabs, leading to potential conflicts.
