If Naruto had his chakra in the real world, he could use it for superhuman feats of strength and speed. Maybe he could run really fast like an Olympic sprinter. Sasuke's Sharingan might give him an almost photographic memory, helping him in academics or in his career as a detective perhaps.
Ruby's speed and scythe - fighting skills could be seen as a unique form of combat in the Naruto world. Her speed might be compared to that of some of the faster ninja like Rock Lee. Her scythe could be modified with chakra - based enhancements. Weiss's Glyphs could be related to some form of ninjutsu seals. She could use her Dust - infused attacks in combination with ninja techniques. Blake's shadow clones and her acrobatic combat style could be similar to some ninja's stealth and agility - based fighting. Yang's strength could be on par with some of the physically strong ninja like Tsunade, and her ability to absorb and release energy could be a new concept in the Naruto world.
His ninjutsu could be translated as some sort of unique Force abilities. For instance, his Shadow Clone Jutsu could become a way to create illusions in the Force that can confuse enemies. It would be like a new form of Jedi mind trick but more physical in nature.
Naruto's ability to learn new techniques quickly might translate into quickly understanding how Pokémon abilities work. He could then come up with unique battle strategies. For example, he could use his Rasengan in combination with a Pokémon's spinning move to create a more powerful attack. Also, his stamina and endurance from being a ninja would allow him to travel long distances in the Pokémon world without tiring easily, which would be useful for exploring different regions and finding rare Pokémon.
If we consider Naruto x Diablo fanfiction, Naruto's ability to create shadow clones could be a huge advantage in the Diablo world. He could send his clones to scout areas filled with demons. As for Diablo characters in the Naruto world, the Barbarian's strength could be comparable to Tsunade's superhuman strength. The Sorceress' magic would be like a new form of chakra - based jutsu that the ninjas have never seen before. They would have to adapt and learn from each other's abilities.
His loyalty in a real - life setting could mean that he'd be the most reliable friend. If his friend was in trouble, he'd drop everything to help. He might work multiple jobs to raise money for a friend who was in financial difficulty, just like he always had his friends' backs in the anime.
Naruto's powers in the Digimon world would be quite different. His chakra, which is a form of energy in his own world, would likely interact with the digital energy of the Digimon world. His Rasengan, which is a concentrated ball of chakra, might be able to disrupt the digital code of some Digimon. Also, his ability to sense chakra could be transformed into a way to detect the different levels of digital energy in the Digimon. His ninjutsu, which are based on hand signs and chakra control, could be combined with the unique abilities of the Digimon he teams up with, creating new and powerful combos. For instance, if he teams up with a fire - type Digimon, his fire - based ninjutsu could be amplified.
Well, for Kakashi, his Sharingan could be used to predict his opponent's moves in the wrestling ring. He could dodge attacks with ease and counter at the perfect moment. It would be like having a super - sense in the wrestling world.
In a fanfiction sense, Naruto's powers would have to adapt to our physical laws. His speed and strength from the chakra could be seen as extraordinary athletic abilities. The transformation jutsu could be used for disguises, which could be both fun and useful. For his more powerful jutsus like the Rasenshuriken, it might be toned down to something like a really powerful throwing technique. His powers would also attract a lot of attention, from both good - intentioned people who want to learn from him and bad guys who want to use his powers for their own gain.
Naruto's physical strength and speed, which are enhanced by his ninja training and chakra, would likely give him an edge in the Matrix. His clones could act as decoys or distractions for the agents. His rasengan, a powerful spinning ball of chakra, could potentially disrupt the digital code of the Matrix.
Naruto's ninjutsu skills could be very powerful in the One Piece world. His Rasengan, for instance, is a concentrated ball of chakra. In the One Piece world, it could be as strong as some of the more powerful Devil Fruit attacks. His ability to run up walls and trees using chakra control could also be useful in the more diverse terrains of the One Piece world, like running up the side of a ship or a rocky island.
