In such a fanfic, Naruto's Nine - Tails chakra could play an interesting role with the Gate of Babylon. The raw power of the Nine - Tails could be harnessed to open up more powerful sections of the Gate or to unlock special items. His ability to enter Sage Mode could also give him an advantage. In Sage Mode, he has enhanced senses and strength. He could use these enhanced abilities to better utilize the items from the Gate. For example, he could accurately throw weapons retrieved from the Gate with greater force and precision while in Sage Mode. Also, his ability to form different chakra natures could interact with the magic of the Gate in unique ways. For example, his lightning - style chakra could be used to charge up a weapon from the Gate, making it faster and more deadly.
Naruto's shadow clone jutsu could be very useful when dealing with the Gate of Babylon. He could send clones into the gate to explore and gather information about the treasures and defenses inside. Meanwhile, his Rasengan, being a concentrated form of chakra, could potentially be used to break through any barriers or defenses within the Gate. Also, Naruto's strong will and determination, which are key to his ninja abilities, could help him resist any negative or corrupting influences that the Gate of Babylon might have.
Sasuke, on the other hand, would be more cautious. He would study the Gate of Babylon's powers first, trying to understand their limits and weaknesses. He might try to use his Sharingan to analyze the weapons and the energy behind the gate. He could then use this knowledge to either control the gate himself or find a way to stop an enemy who has control of it.
Well, it could be a really wild and exciting story. Imagine Naruto's ninja skills combined with the power of the Gate of Babylon from DxD. He might use his shadow clones to quickly access the treasures within the Gate. And his Rasengan could be enhanced with some of the magical items from the Gate. It would be a story full of action and adventure as he battles against the devils in the DxD world using this newfound power.
His chakra control might be affected by the different magical energies in the DxD world. Maybe his chakra could interact with the devil or angelic powers in unexpected ways. For example, his Rasengan could gain new properties if combined with devilish power. His shadow clones might also be able to do things like sense magical auras, which they couldn't do in the Naruto world.
Naruto's ability to use chakra could be a game - changer. His shadow clone jutsu could be used for various strategies, like in battles against the devils in High School DxD. When it comes to Moka, Naruto could use his clones to distract her while he tries to understand her vampire powers.
Kurumi's ability to create clones of herself could be used in tandem with Naruto's shadow clone jutsu. They could create a huge army of clones to overwhelm their enemies. And when the enemies are distracted by the clones, Naruto could use his Sage Mode or Kurumi could use her most powerful time - based attacks to finish them off.
His chakra control is another aspect. In DxD, he could use his chakra control to enhance his physical abilities even more than the normal superhuman strength in the DxD world. He could also use it to sense the presence of different beings, similar to how he senses chakra in his own world.
His speed would likely be enhanced. In the DxD universe, there are fast - moving opponents like the devils and angels. Naruto, already known for his incredible speed in his own world, would need to adapt and become even faster. His rasengan, for instance, might be modified to be more effective against the magical defenses of DxD characters.
The characters' abilities could combine in some really cool ways. For example, Naruto's Rasengan could potentially be infused with the power of a Sacred Gear. This would create a super - powerful attack that has both the destructive force of the Rasengan and the unique properties of the Sacred Gear. Also, the Sharingan from Naruto could be used to analyze and copy the techniques used by the characters in High School DxD. On the other hand, the characters in High School DxD could use their demonic or angelic powers to enhance Naruto's physical abilities, like making him faster or stronger.
Naruto's abilities would bring a whole new dynamic to the Highschool DxD universe. His ability to use chakra to walk on walls and water could give him an advantage in certain terrains or situations. In battles, his ability to sense chakra could help him detect hidden enemies. Also, his summoning jutsu could call upon powerful creatures from the Naruto universe. If these creatures were introduced into the Highschool DxD world, they could change the balance of power. And his various transformation jutsu could be used for disguise or to gain temporary boosts in power.
