Naruto could gain the power of mind control, similar to how Sauron could influence the minds of others. This would be a huge change for Naruto as he is usually all about friendship and persuasion through positive means. Now, he would have to struggle with this new power that goes against his normal moral code and figure out how to use it for good, if possible.
Her powers would likely be more focused on the Uchiha - related abilities. While Naruto has the Nine - Tails' chakra, she would have things like the Sharingan or even the Mangekyo Sharingan. She might be able to use genjutsu more effectively compared to Naruto.
His powers would be a blend. Instead of just chakra - based abilities, he'd have Hellboy's super strength and Liz's fire - based powers. So his Rasengan could be on fire or have a demonic boost. His speed might also be enhanced by Hellboy's inhuman physiology.
His powers would likely include some form of soul manipulation. He might be able to sense the souls of others more acutely, which could give him an edge in battle by predicting his opponents' moves.
His powers would be a blend. He might have superhuman strength like Ares, allowing him to overpower opponents easily. And from Aphrodite, he could have the power of persuasion. So, instead of just using ninjutsu, he could also convince enemies to surrender with his charm.
His powers would likely be a blend of his ninja abilities and some of the powers associated with Shao Kahn. For example, he might have enhanced physical strength like Shao Kahn. His Rasengan could be more powerful, perhaps with an added element of Outworld magic. He could also have the ability to command some of the Outworld minions, similar to how Shao Kahn rules over them.
Well, if Naruto had the Flash's powers in a fanfiction, his character development would likely be sped up in some ways. He could quickly reach places to train or help people, which might make him more confident earlier. He'd be able to avoid attacks much more easily, so his combat skills might develop in a different direction, focusing more on using his speed for surprise attacks rather than brute force like he often does in the original series.
Naruto's powers in the Digimon world would be quite different. His chakra, which is a form of energy in his own world, would likely interact with the digital energy of the Digimon world. His Rasengan, which is a concentrated ball of chakra, might be able to disrupt the digital code of some Digimon. Also, his ability to sense chakra could be transformed into a way to detect the different levels of digital energy in the Digimon. His ninjutsu, which are based on hand signs and chakra control, could be combined with the unique abilities of the Digimon he teams up with, creating new and powerful combos. For instance, if he teams up with a fire - type Digimon, his fire - based ninjutsu could be amplified.
Another aspect of their power interaction could be in the area of teamwork. Naruto is used to fighting as part of a team in his world. Gwynevere, with her different powers, could fit into that team dynamic in a unique way. For example, if Naruto creates a diversion using his shadow clones, Gwynevere could use her magic to attack the enemies from a different angle. Their combined powers could be much more effective than either of them working alone, and they could develop new battle strategies based on how their powers complement each other.
His powers would likely be enhanced to a godlike level. For example, his Rasengan might be able to destroy entire landscapes with a single throw. His speed could be so great that he appears to teleport. His chakra reserves would be seemingly infinite, allowing him to spam powerful jutsus without getting tired.
His powers would be much more physically dominant. He might not rely so much on ninjutsu but more on brute strength like Kratos. He could have the ability to rip his enemies apart instead of using shadow clones.
