As an apprentice to Deathstroke, Naruto's powers would evolve in several ways. His physical strength, which is already significant, could be increased through Deathstroke's intense training regimens. His chakra control might improve to the point where he can perform more complex and powerful jutsu with less effort. Also, Naruto might develop new techniques that combine his ninja abilities with Deathstroke's combat expertise. For instance, he could learn to create clones that can mimic Deathstroke's fighting style, allowing him to confuse and overpower his enemies. Moreover, his ability to adapt to different combat situations, which is a strength of his, would be further honed as he learns from Deathstroke's vast experience in various battles.
His chakra control might improve in a different way. Sesshomaru's precise and refined combat style could force Naruto to have better control over his chakra. For example, he might learn to use his chakra more sparingly like Sesshomaru uses his demonic energy.
If Naruto were Deathstroke's apprentice in this fanfiction, the story might start with Naruto being somehow transported to Deathstroke's universe. Deathstroke, seeing Naruto's potential, decides to take him under his wing. Naruto would bring his chakra - based abilities, which would be something completely new to Deathstroke. This could lead to interesting training sessions where Deathstroke tries to incorporate Naruto's powers into his own combat strategies, while also teaching Naruto how to be a more efficient assassin - like figure. However, Naruto's friends back in his own world might try to find a way to bring him back, which could create a lot of drama.
Naruto's chakra - based powers, like his Rasengan, could be combined with Deathstroke's strategic and combat skills. For example, Deathstroke could use his knowledge of combat tactics to find the perfect moment for Naruto to unleash a powerful Rasengan, maximizing its impact.
Naruto's control over the Nine - Tails' chakra might be different. Since Killer Bee has experience with his own Tailed Beast, he could teach Naruto some new ways to communicate and cooperate with the Nine - Tails. This could lead to Naruto being able to access more of the Nine - Tails' power without losing control as easily as in the original story.
Naruto's powers would evolve in a very different way. Aizen's training might focus on the psychological aspect of combat. So, Naruto's chakra control could be enhanced in a way that allows him to project his presence in a more intimidating way, similar to how Aizen can make others feel his overwhelming power. His ninjutsu could also be modified to have hidden elements, like a Rasengan that has a secondary effect that only activates when the opponent least expects it, just as Aizen has multiple layers of deception in his attacks.
Well, often in fanfiction, Danny's powers evolve as he faces more powerful enemies. The need to defeat a stronger foe forces him to adapt and his powers change accordingly. For instance, he might develop the ability to phase through not just solid objects but also energy barriers. His ghostly wail, which was already a powerful weapon, could become more focused and destructive. Also, when he teams up with other powerful characters, their combined energies or knowledge can lead to his power evolution. They might teach him new ways to use his powers or unlock hidden potential within him. His power evolution in fanfiction is really diverse and depends on many different factors.
Naruto's ability to use chakra could be combined with Deathstroke's physical combat skills. For example, Deathstroke could learn to sense chakra from Naruto and use it to anticipate his opponents' moves better. Naruto, on the other hand, could learn Deathstroke's efficient killing techniques and incorporate them into his ninja attacks in a non - lethal way.
One idea could be that Naruto, as Sarutobi's apprentice, discovers a new jutsu hidden in the old Hokage's personal library. This jutsu could be a powerful fire - style technique that was once used by Sarutobi's master. Naruto would have to train hard to master it, facing challenges like controlling the intense heat. It would also add a new dimension to his combat abilities and make him stand out even more in battles against powerful foes.
Kurama might be the link that brings Naruto into Deathstroke's orbit. Since Kurama is such a powerful and unique entity in Naruto's world, his presence could be what makes Naruto aware of Deathstroke in the first place. For example, Kurama could sense some strange energy similar to Deathstroke's and draw Naruto's attention to it.
Well, in certain 'Naruto can evolve' fanfictions, Naruto's evolution could be related to his mental state. He might grow to have a deeper understanding of the ninja world and his role in it. This could lead to him evolving his combat strategies, like using his talk - no - jutsu in more creative and impactful ways during battles, rather than just relying on brute force. And he could also gain new forms of chakra control that are more refined and powerful.
