In the fanfic, Sakura could use her magical abilities in unique ways in our world. Maybe she'd become a famous magician or use her powers to help people secretly. She'd also have to deal with our social norms and expectations, which could be quite a challenge for her.
In our world, Naruto would face some interesting situations. His bright orange jumpsuit would surely turn heads. He might have a hard time adjusting to modern technology at first. But his ability to make friends would help him out. He could use his Rasengan as a unique party trick. And with his strong sense of justice, he might end up getting involved in community service or even some kind of local hero work, protecting the neighborhood from small - time crooks.
Well, if the Avengers were in our world, there'd be a lot less crime for sure. They could stop bank robberies and terrorist attacks in an instant. Iron Man would be flying around, impressing everyone with his high - tech suit. Captain America would be a symbol of moral goodness, probably giving speeches in schools. And Thor? He'd be the talk of the town with his hammer.
In such a fanfic, Molly might regain his memories in bits and pieces. He could have new relationships with the old crew, perhaps with a mix of familiarity and strangeness.
In a fanfic, if Naruto punched Sakura, it could be due to a major misunderstanding. Maybe Sakura was being controlled by an enemy's jutsu and Naruto, in his haste to stop her from doing something dangerous, resorted to physical force. This would create a huge rift in their relationship, and Sasuke might get involved to either side with Naruto or defend Sakura.
Well, they would probably be very confused at first. The modern world with all its technology like smartphones and cars would be completely alien to them. For example, Tyrion Lannister might be intrigued by the concept of democracy as it's so different from the feudal system in Westeros.
If 'Attack on Titan' events occurred in our world, there would be chaos. Titans would be a huge threat to humanity. Cities would be destroyed, and people would be constantly on the run. Military forces would have to quickly adapt and find ways to fight these giant creatures. Maybe they would develop new weapons similar to the ones in the anime, like the vertical maneuvering equipment. But it would be a difficult battle as Titans seem almost indestructible in some ways.
Well, Naruto would probably be in a great deal of pain. He might double over and be unable to move for a while. It could also lead to a big argument between him and Sakura, with Naruto feeling betrayed and Sakura perhaps realizing she overreacted.
If Sakura Haruno became a Celestial Spirit in a fanfic, it would be a huge transformation. Her physical appearance would likely be more otherworldly, perhaps with a glow and a more fluid form. Emotionally, she might feel a sense of isolation at first as she is different from her ninja comrades. But she could also find a new sense of purpose. She could explore the celestial world, discover new celestial beings, and bring back knowledge from there to the ninja world. For example, she might learn about a new type of energy that could revolutionize the way ninjas use chakra.
If an OC reincarnated as Superman in fanfiction, it would be an amazing transformation. The OC would suddenly find themselves in a world where they are almost invincible. They would have to deal with the public's perception of them, just like Superman does. And they might also bring in some of their own unique traits from their previous life into the role of Superman. For instance, if the OC was a shy person before, they might struggle with the public spotlight that comes with being Superman.
In this fanfiction scenario, Naruto as Luffy would change a lot of things. Firstly, his leadership style which is a mix of determination and the ability to inspire others from his Naruto days would make the Straw Hat crew even more united. His experience in dealing with complex political situations in the Naruto world might help Luffy better navigate the power dynamics among the pirates, the World Government, and the various islands. And when it comes to combat, Naruto's strategic thinking could be applied to Luffy's battles. Instead of just relying on his brute strength and Devil Fruit powers, he could come up with more elaborate battle plans. Also, Naruto's ability to make friends and allies from different backgrounds could expand the Straw Hat crew's network even further.
