Saitama's personality of being humble despite his incredible strength would be a game - changer in the new world. In a world where power - hungry individuals are common, his lack of desire for power would be very strange. He would not boast about his abilities, which could make others underestimate him at first. However, when he does display his strength, it would completely change the power dynamics in the area. His easy - going nature would also mean he could easily make friends with the ordinary people in the new world, rather than just mingling with the powerful or elite. This could inspire a new kind of community where heroes are seen as approachable and not just distant figures of power.
Naruto's outgoing personality would make him very popular in the Pokémon world. He'd easily make friends with other trainers and people in Pokémon centers. This would give him an advantage as he could learn about different Pokémon and training techniques from others more easily.
Naruto's most prominent personality trait is his determination. As Kage of another village, this would drive him to improve the village no matter the obstacles. For example, if it's a village with a weak economy, he'd find ways to boost it. He wouldn't be deterred by the naysayers.
The cultural and social norms of the other world can either help or hinder his rise. If the world values strength and he can prove himself strong, he'll rise quickly. But if it has complex social hierarchies that are difficult to navigate, it could be a challenge. For example, if there are strict caste systems, he may need to find ways to work around or within them. Also, the geographical features of the world could play a part. If it has dangerous areas that he can overcome, it could earn him respect and status.
One interesting plot could be Saitama arriving in a world full of magic. He might be confused at first by the new rules. For example, instead of using his physical strength directly, he has to figure out how to use magic to defeat powerful magical creatures. Another plot could be Saitama befriending a group of underdog adventurers. They initially doubt his abilities but are soon amazed as he effortlessly takes down the toughest foes. He could also end up in a world where there's a tournament to decide the strongest being, and Saitama, being his usual self, just wants to participate for the fun of it but ends up dominating the whole thing.
Percy Jackson's personality could change quite a bit in another world in fanfiction. His sense of humor might be affected as the new world may not have the same cultural references that he's used to in his own world. He could become more solitary as he tries to figure out this new place on his own. However, his underlying sense of justice would likely remain. He would still be drawn to help those in need, but he might go about it in different ways. He might also develop a new sense of pride in being able to adapt and survive in this new world, which could change how he presents himself to others.
He could become more cautious at first. Since it's a new world, he doesn't know what to expect, so he might hold back his usual boldness.
Well, Percy's water - controlling powers could have a huge impact. He could manipulate the water sources in Westeros, which would be crucial for battles and also for the survival of regions during droughts. For example, in a siege situation, he could flood the enemy's camps or create water barriers. His ability to communicate with sea creatures might also give him an edge in naval battles or in exploring the seas around Westeros. And his demigod strength and speed would make him a formidable fighter in the often - brutal battles of Westeros.
His return could cause a stir among the old families. The Blacks were a powerful family, and his return might shift some power dynamics. Also, those who knew him as a Death Eater would be very suspicious.
Their relationship could have a huge impact. If they get along well, they could be a powerful force for peace. They could use their status as jinchuuriki to bridge gaps between different villages. For example, by showing that jinchuuriki can work together and not be feared.
Naruto's energetic personality would likely make him a very active pilot. He'd be constantly looking for ways to engage the enemy and wouldn't be afraid to take risks.
