One possible consequence could be an immediate power boost. Since Dark Naruto represents the repressed and negative aspects of Naruto, absorbing it might give Naruto access to a new level of strength that was previously locked away. This new power could be both physical and mental, allowing him to face stronger opponents.
One consequence could be an increase in Naruto's power. Since Dark Naruto represents his repressed negative emotions and power, absorbing it might give him a boost in strength and abilities. He could gain new jutsu or have enhanced versions of his existing ones.
One possible consequence is that he might become more powerful. With his dark emotions out of the way, he could focus better on his training and unlock new abilities. Another consequence could be that he becomes more isolated. Since his dark emotions were a part of what made him relatable to others, without them, he might seem distant.
Yes, it could be considered a relatively new concept as the amount and variety of fanfiction has exploded in recent years, and the idea of Naruto 'absorbing' these diverse fan - created ideas is something that has emerged as a result of the growing and evolving fan culture.
In some fanfictions, when Naruto absorbs the bijuu, he might gain overwhelming power. This could lead to him being able to easily defeat powerful enemies that were previously a threat. For example, he could single - handedly take on the Akatsuki without much difficulty.
One common ability is the Sharingan. It's a very powerful ability from the Uchiha clan. Another could be some kind of elemental control like the ability to manipulate lightning better. Sometimes he might absorb the ability to heal quickly, which is quite useful in battles.
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.
Well, it could enhance his jutsu arsenal significantly. Orochimaru has a vast knowledge of various jutsus. Naruto might gain access to Orochimaru's snake - based jutsus like the Hidden Shadow Snake Hands. Also, Orochimaru is very proficient in forbidden jutsus. Naruto could potentially have a better understanding of these dangerous techniques, but he would also have to deal with the darker aspects of Orochimaru's power and the possible corruption it might bring to his own chakra nature.
When Naruto absorbs Zetsu in the fanfiction, it could impact his mental state as well. Zetsu has been involved in many dark and devious plans. Naruto might have to struggle with the knowledge and influence of those. However, on the positive side, Naruto could use Zetsu's ability to communicate with the plants and gather intelligence from the natural world. This would expand his range of information sources and give him an edge in strategic planning during battles.
