If Naruto was born in Ame in fanfiction, his relationships would be vastly different. He wouldn't have the same bond with characters like Iruka or Kakashi. Instead, he'd form connections with people in Ame, who might be more focused on survival and power - grabbing. His enemies would also be different, perhaps facing more internal power struggles within Ame rather than the external threats that Konoha usually deals with.
He might develop better water - based jutsu skills. Since Ame is a rainy place, he'd have more opportunities to practice with water. His stealth abilities could also be enhanced as Ame's environment might require more sneaking around.
In some fanfictions, if Naruto was born in Ame, he might have a very different upbringing. He could be exposed to the harsh environment and unique culture of Ame from the start. This might make him more cynical or street - smart compared to his original self in Konoha.
His powers might adapt to the urban environment. His Shadow Clone Jutsu could be used for distraction during heists or when facing gangs. For instance, he could send clones into different alleys to confuse the criminals. His ability to sense chakra might be tweaked to sense danger or the presence of super - villains in Gotham. Maybe it would work like a sixth sense for him in this new setting.
His relationships would be very different. He might not have the same bond with Sasuke and Sakura. Instead, he could form closer relationships with the older generation of ninja. For example, he might be friends with Kakashi when Kakashi was still a young and up - and - coming ninja. His relationship with the Hokage at that time would also be different. He could be seen as more of a protege to them rather than the young outcast he was in the original story.
He'd probably have a different set of enemies. In Ancient Greece, the threats might be more centered around the local myths and power struggles. For example, he could be in the middle of a feud between two powerful city - states, each with their own godly patrons.
His life would change drastically. He would be a being of immense power. He would no longer have to fear the wrath of the Olympians as he would be on a similar or even higher level. He could shape the world as he wished.
His chakra abilities might be affected by the presence of Dust in RWBY's world. Maybe he could combine Dust with his jutsu. For example, using fire - type Dust to make his Fireball Jutsu even hotter. His physical abilities like speed and strength would still be an advantage, but he'd have to learn to use them in the context of fighting Grimm and other RWBY threats.
His training would change. He'd likely focus more on swordsmanship and the Hatake clan's specific jutsu. Maybe he'd be taught by the clan elders instead of the usual Leaf Village instructors.
His living situation would be different. He'd live in the Hyuga compound, which is a very traditional and family - centered place. He'd probably have a proper family structure for the first time. And he'd be surrounded by people who are highly skilled in combat and chakra control.
If Naruto was adopted by Rias in fanfiction, his life would take a completely new direction. He would be in a world full of magic and supernatural beings. His daily routine would change from ninja training to learning about devil magic and the ways of Rias's peerage. His relationships would shift too. He might form strong bonds with the members of Rias's group, sharing his own stories of growing up as an outcast in the ninja world. His combat style would also evolve as he incorporated elements of devil magic into his ninja techniques. And his presence could potentially change the power dynamics within Rias's peerage, bringing new strategies and ideas to their battles and operations.
