In fanfiction, when Naruto absorbs animals, it might lead to a change in his personality. If he absorbs a predator like a wolf, he could become more aggressive or assertive. On the physical side, his body might adapt to the absorbed animals' traits, which could cause some difficulties in his normal ninja activities at first. Socially, some people in the Naruto world might see him as a freak or a powerful new threat, depending on their views.
One consequence could be that he becomes overly powerful. His new - found ability to absorb chakra might make him a force to be reckoned with, changing the power dynamics in the fanfiction world. Enemies may fear him more, and allies might start to rely on him even more heavily.
One consequence could be new powers. If he absorbs the DNA of a powerful ninja, he might gain their unique abilities. For example, if it's from a ninja with ice - based powers, Naruto could potentially start to use ice - based jutsu. Another consequence could be changes in his appearance. The absorbed DNA might have physical traits that start to show up on Naruto, like different eye color or hair texture.
There could be physical changes too. Naruto might have a new form that combines his own features with Momoshiki's. His body could become more resilient, like Momoshiki's, and he might have a different chakra signature. This new form could attract the attention of other villains in the Naruto universe, either out of fear or the desire to steal his power. Moreover, his relationships with other characters like Sasuke could be affected, as they have to adapt to this new Naruto who has absorbed Momoshiki.
He could gain new and powerful abilities. For instance, if he absorbs a Sharingan - like bloodline, he might gain enhanced vision and the ability to copy jutsus more effectively. But there could also be negative consequences. His body might reject the new bloodline at first, causing him pain and internal conflict.
One consequence could be a change in his personality. If he absorbs the souls of evil - natured people, there might be a dark influence on him. For example, he could become more aggressive or cynical.
Well, it really depends on how the author of the fanfiction writes it. One possibility is that Naruto's personality could be affected. Since the Gedo Mazo is associated with negative and powerful forces, Naruto might struggle with darker impulses. However, he could also use this new power to protect his friends and the village in ways he couldn't before. Maybe he could even find a way to purify the dark chakra he absorbed from the Gedo Mazo and turn it into a positive force for good in the fanfiction world.
One consequence could be a change in his fighting style. With Samehada's absorption ability, Naruto could start using more defensive and counter - attacking strategies. He might be able to absorb an opponent's chakra - based attacks and then use that energy against them. Also, his relationship with his friends and allies could be affected. They might be a bit wary of his new power at first, but as they see Naruto using it for good, they would come to accept it.
The most immediate consequence would be a huge power boost for Naruto. He'd likely gain abilities like teleportation, space - time manipulation, and extreme chakra control. This could make him a target for those who want that power. Also, it might affect his mental state as he tries to cope with the sudden influx of power and the knowledge that comes with Kaguya's abilities.
When Naruto absorbs Kaguya in the time travel scenario, it's likely to cause chaos. His understanding of chakra and the world around him would be completely transformed. He may be able to access new dimensions or abilities that were previously unknown. However, this could also attract the attention of dark forces or ancient evils that were previously dormant, forcing Naruto to deal with threats he may not be fully prepared for.
The consequence might also be a shift in the balance of power in the Naruto universe. With all that chakra, Naruto could potentially change the political situation. He could end wars single - handedly or force the different ninja villages to re - evaluate their strategies. Moreover, his own physical and mental state might be affected. There could be a struggle within him to keep his identity intact while dealing with such an overwhelming power source.
