If Naruto had Sans powers in fanfiction, he would become extremely powerful. His combat abilities would be enhanced greatly. He could use Sans' teleportation skills to quickly move around the battlefield, catching his enemies off - guard. His attacks might also gain some of Sans' unique characteristics, like the ability to bypass defenses in unexpected ways.
In a fanfiction scenario where Naruto has Rikudou Sennin's powers, Kyuubi's chakra, and the Rinnegan, his power level would skyrocket. The Rikudou Sennin powers would enhance his understanding of chakra and life itself. The Kyuubi's chakra would boost his physical and chakra - based abilities even more. And the Rinnegan? That would open up a world of new jutsu possibilities. He could potentially reshape the Naruto world as we know it, perhaps even finding new ways to bring peace between the villages.
If Naruto had Superman's powers in fanfiction, he would be nearly unstoppable. His existing ninja skills combined with Superman's flight, super strength, and heat vision would make him a formidable force. He could easily defeat his enemies in the Naruto universe, like Orochimaru or Pain, without breaking a sweat.
Well, he could use the power to control plants during battles. He might be able to create thick vines to trap his enemies or make plants grow rapidly to block attacks. It would add a whole new dimension to his combat abilities.
If Naruto had Kryptonian powers, his strength would be off the charts. He could do things like punch through solid rock without breaking a sweat. His durability would also be enhanced, so attacks that would normally harm him would have little to no effect.
If Naruto had Wesker's powers in a fanfic, he would be extremely overpowered. His physical abilities like speed, strength, and agility would be enhanced to a superhuman level. He could probably use his Sharingan (if he still has it in this scenario) in combination with Wesker's powers to anticipate his enemies' moves even better. His Rasengan might also gain new properties, like being able to be launched with the extreme force that Wesker can exert.
If Naruto and Sasuke had a Potara fusion in fanfiction, their powers would be a blend of their individual strengths. Naruto's ability to use the Nine - Tails' chakra would combine with Sasuke's Sharingan and Rinnegan powers. They might gain the ability to teleport long distances instantly, similar to how Sasuke can with his Rinnegan. Also, their combined combat skills would make them nearly unbeatable in battle, as they could switch between Naruto's close - range, brute - force attacks and Sasuke's more precise, long - range jutsu with ease.
He'd be extremely powerful. Accelerator's power of vector manipulation would give Naruto a whole new level of combat ability. He could deflect attacks with ease and launch powerful counter - attacks. His movement would also become more precise and unpredictable.
One potential drawback could be that Naruto might accidentally hurt his friends or allies while using his super - speed. If he's not fully in control, he could run into them or cause a gust of wind that knocks them over. Another issue could be that he might rely too much on his speed and neglect his other ninja skills, like his shadow clones or his ability to sense chakra.
In this fanfiction, the prototype powers could be something like an early form of chakra manipulation that is different from the traditional Naruto world's chakra use. It might be more raw and unrefined, with the potential for new and unique jutsu.
