One possible consequence is new and unexpected abilities. For instance, if his DNA is changed to incorporate some sort of spirit energy, he could gain the ability to communicate with the dead. Another consequence could be changes in his appearance, like his hair color or eye color changing. This can also lead to social isolation as his friends might not recognize him at first.
One idea could be that Naruto gains new powers. For example, if his DNA was changed to have some Uchiha traits, he might be able to use Sharingan - like abilities. This could completely change the way he fights and strategizes in battles.
Naruto's view of himself and his purpose in life could also change. He might start to question his identity as the Jinchuuriki of the Nine - Tails. With new DNA - based powers, he could feel like he has a different role to play in the ninja world. He might explore new ways to use his powers for the greater good, which would be a significant development in his character.
Maybe it's from a powerful villain. In some fanfictions, this could be a really interesting twist. The DNA of a villain like Orochimaru could give Naruto some of his snake - like abilities or his knowledge of forbidden jutsu. However, Naruto would then have to struggle with the darker instincts that might come with that DNA. Another possibility is that it could be from an ancient and powerful demon. This would bring out a whole new set of challenges and powers for Naruto to deal with.
In some Naruto fanfictions, Naruto might absorb DNA through special jutsu or abilities. For example, he could have a unique kekkei genkai that allows him to take in and assimilate the genetic material of others. This could potentially give him new powers or abilities related to the DNA he absorbs, like if he absorbs the DNA of a Sharingan user, he might gain some form of Sharingan - like abilities.
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.
Perhaps he would change to Naruto Storm. 'Storm' can represent his powerful and sometimes tempestuous nature. In the series, Naruto has shown great strength and determination that could be likened to a storm, which is both destructive and at the same time a force of change.
In some Naruto DNA fanfiction, the concept of mixing DNA from different clans, like Uchiha and Hyuga, is explored. It might show how a character with such a mix could have extraordinary abilities, such as the Sharingan combined with the Byakugan's long - range vision. This could create a whole new dynamic in battles and relationships within the story.
In some fanfictions, Naruto's DNA might change due to experimental jutsu gone wrong. For example, a mad scientist - type character could try to infuse him with a powerful demon's essence, which alters his DNA. This could lead to new abilities like enhanced strength and the ability to control different elements more effectively.
In fanfiction, if Naruto was injected with DNA, he could gain new powers. For example, if it was the DNA of a powerful and ancient creature, he might be able to control new elements or have enhanced physical abilities like super strength or speed. This could also change his appearance, perhaps giving him some physical traits of the source of the DNA.
