Naruto could bring his chakra powers. He could use his shadow clone jutsu to confuse enemies or gather information. His Rasengan could be a powerful weapon against any threats in the Twilight world, whether it's rogue vampires or other dangerous creatures.
Naruto's powers would be a game - changer. His chakra control allows him to walk on walls and water, which could be useful in the Twilight setting. He could use his transformation jutsu to disguise himself and gather intelligence. His Wind - Style jutsu could be used for both offense and defense. And his experience in battles against powerful foes in his own world would make him a formidable force in protecting Bella and dealing with the various supernatural elements in the fanfiction world.
Naruto might gain the ability to use magic weapons like Erza. Since he's a quick learner, he could master the use of different magical swords or armors. He could infuse his chakra into these weapons to make them even more powerful. For instance, a sword that can cut through any material when combined with his chakra and also has the ability to cast magic spells.
He would bring the power of flight, which is not common in the Naruto world. His ability to sense ki could also be used to detect enemies or allies from a great distance. His Saiyan tail, if he still has it, could be a unique feature. He might also have the ability to heal quickly, like after a tough battle, which is different from the medical ninjutsu in Naruto. His power to break through limits, like achieving new Super Saiyan levels, could inspire the Naruto characters to strive for greater power.
He could inherit some of the unique Uzumaki sealing techniques. Since Mito was an Uzumaki and was known for her sealing abilities, Naruto might be more proficient in that area. Maybe he could use seals in combat more effectively or create more powerful sealing jutsu.
Since Yoruichi has strong spiritual energy in her world, Naruto might inherit some form of enhanced chakra that has spiritual aspects to it. This could give him new jutsu or abilities that are a blend of his original ninja skills and this new spiritual - chakra power. For example, he could use his new power to sense things in a different way, like Yoruichi can sense spiritual presences.
He would bring his chakra powers for sure. His ability to use jutsus like Rasengan would be a powerful addition. Also, his enhanced physical abilities due to being a demigod, like super strength and speed, would make him a formidable opponent in the DxD battles.
Naruto has his powerful chakra and his ability to use shadow clones. Shippo can transform into different things. They could combine these powers in really interesting ways. For example, Shippo could transform into Naruto's shadow clones to create a more diverse and confusing attack for their enemies. Or Naruto could use his chakra to enhance Shippo's transformation abilities, making them more powerful and longer - lasting.
Naruto would bring his vast array of ninjutsu skills. For instance, his ability to walk on water and walls could be useful in different terrains in the Big Hero 6 world. His chakra control would also be a great asset. He could transfer chakra to heal the team members if they got injured. His summoning jutsu would allow him to call for help from other creatures. Also, his nine - tailed fox chakra could give him a huge power boost when needed.
He could inherit time - related powers. Maybe the ability to slow down or speed up time, which would be a huge advantage in battles. He might also be able to see into the past or future, which could help him in making strategic decisions.
As a devil, Naruto would likely have enhanced physical abilities like super strength, speed, and agility. He could also have some sort of demonic energy manipulation, maybe like a blue - colored chakra with devilish properties. His shadow clone jutsu could take on a new form, perhaps with each clone having a small amount of devilish essence. And he might be able to use some basic devil magic, like creating small portals or summoning minor devil creatures.
She could have the power of wind manipulation like Temari. This would allow her to create powerful gusts of wind and use them for both offense and defense. Also, she might inherit Naruto's large chakra reserves, which would give her the stamina to perform complex jutsus for a long time.
