His ninjutsu might be used in different ways. For instance, his Rasengan could be modified to work with the local materials or energy sources in Tifa's world. His ability to move quickly and stealthily would still be useful, but he might have to adapt to new terrains and environments. Maybe he'd use his chakra to enhance Tifa's fighting skills too.
Well, Naruto's shadow clone jutsu could be used for various practical purposes in Tifa's world. He could use clones to help with daily tasks like farming or building. His transformation jutsu could also be used in interesting ways, perhaps to blend in better with the local population or to deceive enemies in a different way than in his original world. And his Nine - Tails chakra, if it still exists in this new world, could be a major factor in changing the power balance, but he'd have to learn how to control it in a world with different power systems.
Naruto's ability to sense danger could be enhanced in Tifa's world. Since it's a different setting, there would be new threats and challenges. His chakra control could also develop further as he tries to adapt his abilities. For example, he might learn to use his chakra to interact with some of the unique magical elements in Tifa's world, creating new and unexpected combinations of powers.
His abilities might be adapted to fit the new environment. For example, his ninjutsu could be less about fighting demons and more about dealing with human adversaries in a more stealthy and strategic way. His ability to sense danger could be enhanced in the context of Raymond's dangerous world.
His abilities might be enhanced by the demonic powers associated with Sirzechs' world. For example, his Rasengan could take on a more demonic form, with added destructive power. Maybe he could also gain the ability to teleport short distances like some demons in Sirzechs' world, which would give him an edge in combat.
Naruto's chakra could be affected in different ways. Maybe his chakra would take on some properties of the Xenomorphs' acidic blood. So, when he uses certain jutsu, it could have an acidic effect as well. Also, his ability to sense danger could be enhanced. The Xenomorphs have a natural sense of stealth, and Naruto could inherit this, making it even harder for enemies to surprise him. He could also use his shadow clones in more creative ways, like using them as decoys to draw out the Xenomorphs' attacks and then counterattack.
Their abilities could become more lethal. Since the Akatsuki often deals with dangerous missions, the OC might be trained in more deadly jutsu. For example, if they had a basic fire - style jutsu before, they could learn to combine it with other elements under the Akatsuki's tutelage. They could also gain better stealth abilities, as the Akatsuki is known for its secrecy. Maybe they learn how to mask their chakra better like Kakuzu.
His abilities would likely take a very different turn. Orochimaru could introduce him to some dark and powerful chakra - based techniques. Naruto might learn to manipulate his chakra in more insidious ways, perhaps using it to control others or for stealth attacks.
Naruto's shadow clone jutsu would be a great advantage. He could send clones to explore different areas in the Pokémon world to find rare Pokémon. His chakra control could also be used to communicate with Pokémon on a deeper level. He might be able to sense their emotions and needs better. His ninjutsu skills could be combined with Pokémon attacks to create unique battle strategies. For example, he could use his fire - based jutsus to enhance the power of a fire - type Pokémon's attack.
Naruto's chakra control could be seen as a form of wandless magic in the Harry Potter universe. His ability to create shadow clones might be adapted to create illusions that are more like the wizarding world's magic. For example, instead of a physical clone, it could be a magical apparition - like clone.
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.
His story would change a great deal. For one, his living environment would be among the Akatsuki members. This means he'd be surrounded by different types of ninjas with different motives. He might not have that lonely childhood he had in the original story. Konan could give him a more stable family - like feeling. And his skills would be different. He'd likely be more proficient in paper - based techniques.
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.
