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.
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.
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.
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.
If Naruto is trained by Deathstroke in fanfiction, his character would change in multiple ways. For one, he might lose some of his naivete. Deathstroke's world is a harsh one, and Naruto would have to adapt. He could become more calculating and less likely to jump into a fight without thinking. His relationships with his friends might also change. He might start to keep them at a bit of a distance, not wanting to put them in danger as a result of his new, more dangerous fighting style.
His water - controlling powers could be developed for more tactical uses. Instead of just using it in battles against monsters, he could learn to use it for stealth operations, like creating a mist screen to hide movements. Nick Fury might also encourage him to explore other aspects of his powers, like how he can communicate with sea creatures. This could lead to Percy using them as informants or even as allies in missions.
Percy's demigod powers would likely adapt to his assassin lifestyle. He could use his ability to breathe underwater to access hidden underwater lairs or escape pursuers. His strength, which is already enhanced as a demigod, could be further refined to be more precise for things like silent kills. He might also develop new powers related to the assassin's skills, like being able to move faster in the shadows, which could be a combination of his natural speed and some sort of new power influenced by his assassin upbringing.
Naruto's chakra - based abilities would probably be combined with Deathstroke's combat skills. For example, he could use his Rasengan while also making quick, precise slashes with swords like Deathstroke. His ability to sense chakra could be enhanced in a way that mimics Deathstroke's heightened senses in combat.
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.
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.
