If we consider the Sharingan ability from Naruto, a character like Sasuke could use it to predict the movements of the zombies more accurately. This could be combined with the strategic thinking of the Highschool of the Dead characters. They could plan out how to best use Sasuke's ability to avoid large groups of zombies or to lead them into traps. The Highschool of the Dead characters might also learn some basic ninja stealth techniques from the Naruto characters, allowing them to move more quietly through the school corridors filled with zombies.
The Phenex's ability of immortality could give Naruto an edge in battles. He could be more fearless in combat knowing that he has a sort of 'backup' in case things go wrong. And Naruto's chakra could potentially enhance the Phenex's fire abilities. For example, if a Phenex character were to use their fire with Naruto's chakra infusion, the fire could become more powerful and have unique properties.
Inuyasha's demon blood could interact with the devilish powers in Highschool DxD. His berserker mode when his demon blood takes over could be enhanced or controlled by some of the devil's magic. On the other hand, the characters in Highschool DxD could learn from Inuyasha's group about fighting without relying too much on modern technology. For example, the simple yet effective fighting styles of Sango and Miroku could inspire some of the characters in Highschool DxD to improve their hand - to - hand combat skills.
Well, Issei's Boosted Gear could potentially combine with Ichigo's Zangetsu. The power - amplification aspect of the Boosted Gear might enhance Zangetsu's cutting ability. Imagine Issei lending his power to Ichigo during a tough fight against a powerful Arrancar or something.
Scorpion is known for his deadly puppet attacks. If combined with Naruto's Rasengan, it could create a new and powerful attack. Maybe Naruto could infuse his Rasengan into one of Scorpion's puppets, making it a super - powered weapon that can break through tough defenses. Also, Naruto's Nine - Tails chakra could enhance Scorpion's puppets, giving them more strength and speed.
In this crossover, Naruto's Rasengan could be a powerful weapon against the zombies. He could spin through a group of zombies, taking them out in one go. Hinata's Byakugan could be useful for surveillance, being able to see in all directions and detect any approaching zombies long before they get close. Shikamaru, with his high intelligence, could come up with strategic plans to navigate through the zombie - infested high school, using the abilities of both the Naruto and Highschool of the Dead characters effectively.
If Naruto was in the Splatoon world, his Shadow Clone Jutsu could be used in interesting ways. He could send clones to cover more ground during an ink battle, confusing the enemy. And for the Inkling's part, their ability to swim in ink could help Naruto move around in ink - filled areas more easily. They could also use their ink guns to provide cover for Naruto while he attacks up close.
Well, if Izaya from Durarara and Shikamaru from Naruto were to team up, Izaya's intelligence in manipulating people and Shikamaru's strategic thinking could create some really devious plans. Shikamaru could use his shadow - binding jutsu to physically restrain opponents while Izaya uses his words to mislead and confuse their enemies. Another example is if Celty's shadow powers were combined with Naruto's chakra - enhanced strength. Naruto could use Celty's shadows to extend his reach in battle, like creating shadow - arms that are empowered by his chakra.
Naruto's ability to use chakra and his shadow clone jutsu could be combined with the Ninjago ninjas' elemental powers. For example, Naruto could create shadow clones to help Kai with his fire - based attacks in a battle.
The sharingan ability from Naruto's world could be used in an interesting way with the Voltron technology. For example, a character with the sharingan could quickly analyze the weak points in the Galra's defenses or the mechanisms of the Voltron lions themselves, allowing for more efficient repairs or strategic attacks. And Voltron's ability to form into a giant robot could be used as a cover or a platform for Naruto characters to perform their long - range jutsus from a safe vantage point.
Naruto's ability to use chakra could be combined with Batman's gadgets. For example, Naruto could use his chakra to power up some of Batman's energy - based weapons. Batman's detective skills could help Naruto in his ninja missions in the Naruto world. He could analyze the enemy's patterns and strategies better. Also, Naruto's shadow clone technique could be used for reconnaissance in Gotham, while Batman's stealth could be applied in the Hidden Villages for spying on potential threats.
