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 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.
If Deku had a quirk in fanfiction, it would likely impact his character development. He might have become more powerful quicker or taken on different enemies. The story could become much more action-packed or focus on different themes.
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.
Deku's One For All power could be seen as a sort of super - strong magic in the Fairy Tail universe. It could be that he has to learn to control it in a different way, like using the Fairy Tail guild's training methods. Maybe he'd have to combine it with some form of Fairy Tail magic to make it even more powerful.
It could make for a really exciting and unique story. Deku's growth and challenges would be measured in a more structured way, adding a new layer of excitement to his journey.
