Naruto's shadow clone jutsu could have a new twist. Instead of just creating clones for battle, the clones could be used to perform tasks around the One Punch Man universe, like helping to rebuild after a villain attack. And his ability to use nature energy could be combined with Saitama - like strength, allowing him to deliver punches that not only have physical force but also some kind of energy - based impact.
His ability to move would change drastically. Vader has his slow, yet intimidating, mechanical walk. Naruto might adopt a similar gait as he becomes more like Vader. In terms of combat, Naruto's Rasengan could be combined with the dark side of the Force. It could become a more destructive and corrupting attack, maybe with a black, swirling energy around it. Also, his ability to sense others, which was based on chakra before, could now be a more Force - like sense, allowing him to detect enemies even through walls and over long distances.
Genos would probably be even more in awe of Saitama. He already idolizes him, but with Saitama being S - Class, Genos might see him as even more untouchable. He could become more protective of Saitama's new status, trying to fend off any detractors or those who might try to take advantage of Saitama.
His ninjutsu might be enhanced. For example, his Rasengan could gain new properties due to the influence of Campione powers. His speed and strength, which were already considerable in the Naruto world, could be further increased. Maybe his ability to sense danger, which was related to his ninja training, could be upgraded to a more supernatural level in the Campione world.
For example, if we consider Frozone's ice - making ability and Genos' fire - based attacks in a fanfiction context. They could create a really unique balance. Genos could provide the heat source and Frozone could use his ice to direct and shape it into powerful ice - fire attacks. Also, Elastigirl's stretching ability could be used in combination with Tatsumaki's telekinetic powers. Elastigirl could stretch out her limbs and Tatsumaki could use her telekinesis to fling Elastigirl around like a weapon, reaching far - off enemies.
His relationships would change a great deal. His friends might feel a bit overshadowed by his new power. For instance, Sasuke might feel even more compelled to compete with Naruto, but also realize the futility of it. His relationship with Sakura could become a bit strained as she might be in awe and a bit intimidated by him now.
Well, Naruto's shadow clone jutsu could be really useful in a fight alongside Saitama. The clones could distract enemies while Saitama gets in a powerful punch. And Saitama's super strength could help Naruto in situations where brute force is needed more than ninjutsu. For example, if they had to break through a really thick and magically reinforced wall.
Well, in these fanfictions, characters' abilities often change due to the influence of the gamer elements. The gamer character may be able to distribute stats like in a role - playing game. So, they could boost a character's intelligence stat, which might then allow that character to come up with more complex battle plans. Another way is through item acquisition. A character might find a game - item that gives them temporary flight ability or enhanced vision, completely changing their combat capabilities in the One Punch Man world.
His abilities would become more lethal. Instead of using his Rasengan to just defeat opponents, he might use it to kill. His speed and stealth would be enhanced for more effective assassinations. His ability to gather information, like he did as a ninja, would be used in a more sinister way to track down his targets.
Saitama's one - punch ability would completely overpower most of the beings in the Overlord world at first glance. However, Ainz has a vast array of magic and strategic abilities. He could potentially use his knowledge of magic and the terrain in the Overlord world to his advantage against Saitama, even if he couldn't defeat him directly. For example, he could create illusions or traps.
When it comes to Genos' abilities, the Avengers would be intrigued. Genos' ability to fire intense energy blasts could be a great asset in battles. Hawkeye might be thinking about how Genos could provide cover fire or take out tough enemies from a distance. But the Avengers would also be a bit worried about Genos' lack of emotional control at times. In his pursuit of power and revenge, he can be a bit reckless. The Avengers would need to work with him to make sure he doesn't go overboard. Also, Genos' loyalty to Saitama would be something they would need to understand, as it might influence his decisions within the team.
