In such a fanfiction, the plot could take a turn where Naruto is no longer fully trusted by his friends. His behavior might change due to the DNA injection, and this could cause rifts in his relationships. On the other hand, it could also open up new storylines. For example, the source of the DNA might have a connection to an ancient prophecy, and Naruto now has to fulfill that prophecy. He may also face challenges from those who want to study or steal his new - found abilities.
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.
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.
Well, for one, Naruto's physical strength would be off the charts. The Saiyan DNA could make him stronger with each battle he endures, thanks to the Zenkai boost. And the Kryptonian DNA would grant him powers like super strength, flight, and heat vision. His speed would also increase dramatically. He could move at super - fast speeds like a Saiyan in their transformed states and also with the enhanced speed that Kryptonians possess. His chakra control might also be affected. He could potentially use his chakra in new and more powerful ways, perhaps even combining it with the energy manipulation abilities that Saiyans have. All in all, he would be a completely different and much more powerful Naruto.
Well, it could make him more complex. Absorbing DNA might bring in new skills and instincts. He could become more confident as he gains new powers. Maybe he'll struggle with new urges related to the DNA he absorbs, like if it's from a more aggressive ninja. This could lead to internal conflicts that shape his growth in different ways than in the original story.
In a Naruto kills Kabuto fanfiction, it would likely have a big impact on Naruto's character development. Naruto is usually about saving and redeeming his enemies. Killing Kabuto would be a departure from his normal values. This could lead to internal conflict within Naruto. He might struggle with guilt or question his own actions. On the other hand, it could also show his growth in a different way, that he's willing to do whatever it takes to protect his friends and the village. And from a plot perspective, it would create a rift between Naruto and those who believe in second chances, like Tsunade.
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.
Well, it could make Naruto a much darker character. Instead of his usual optimistic self, he might be filled with vengeance. This would change the dynamics of his relationships. His friends would have to deal with this new, brooding Naruto. Also, it might slow down his progress in becoming a stronger ninja as he has to first deal with the trauma of the torture.
Well, in this fanfiction scenario where Naruto kills the Uchiha clan, it would mean the end of the Sharingan bloodline in a very unexpected way. This would have huge implications for the ninja world. Without the Uchiha, there would be no potential for the Mangekyou Sharingan or the Eternal Mangekyou Sharingan. The balance of power in the ninja world might shift as the Uchiha were quite powerful. And Naruto himself would be a very different character. He's always been about protecting and saving people, so this act would make him a much darker and more complex figure, almost an anti - hero.
Well, in this fanfiction scenario where Naruto is Deidara's brother, it would be a huge shock to both the characters and the readers. Naruto has always been seen as a pure - hearted hero of the Leaf, and Deidara was a dangerous member of the Akatsuki. Naruto's character development could take a different turn. Maybe he would have a different view on the Akatsuki and their motives. He might even try to convert Deidara to the side of good, which would be a very interesting story arc. And his friends in the Leaf might be very suspicious of him at first, but Naruto would surely prove his loyalty in his own unique way.
In a fanfiction where Naruto has leukemia, the plot could take a very different turn. Naruto's usual exuberance and energy would be dampened by his illness. His fights would be more difficult as he would have to deal with the physical weakness brought on by leukemia. The story could focus more on his internal struggle, his fear of dying before achieving his dreams. His friends like Sasuke might have a change of heart seeing Naruto so vulnerable. It could also lead to new alliances in the ninja world as different clans might come together to try and find a cure for Naruto's condition.
