Think about Naruto's Nine - Tails chakra mode. If an Assassin were to somehow harness that power, they would become an extremely formidable force. The Assassin could move at incredible speeds and have enhanced strength. Meanwhile, Naruto could learn from the Assassin's training in using different types of weapons. He could combine his own ninja tools with the Assassin's weapons, like attaching a kunai to the hidden blade for a more deadly attack. And the Assassin could teach Naruto how to better analyze his enemies' weaknesses using their own combat analysis skills.
Well, Naruto's ability to use chakra and perform jutsu like the Rasengan could be combined with an Assassin's stealth and parkour skills. For example, an Assassin could use chakra to enhance their speed and jumps while Naruto could learn to be more stealthy using Assassin techniques.
Well, his mobility would be different. In the Assassin's Creed world, he might have to adapt to the parkour - like movements. His ninja run could be combined with the assassins' free - running. Also, his jutsu might be affected by the different magic or energy systems in Syndicate. For example, his fire jutsu might be weaker or stronger depending on the ambient energy in the area.
Naruto's shadow clone jutsu would have new applications. Instead of just using it for combat in his own world, in Assassin's Creed 3's setting, he could use the clones for gathering information. The clones could blend in with the crowds in cities like Boston or New York in the game. Also, his Rasengan, which is a powerful attack in his world, could be modified. Maybe he could use chakra control to make it more like a stealth weapon, for example, by making it a smaller, more concentrated blast that can be used to silently take out enemies from a distance.
Ruby's scythe - wielding skills could be enhanced with Assassin's Creed combat techniques. Her speed could be used to quickly assassinate enemies in close combat. Weiss could use her glyphs in combination with Assassin stealth, for example, creating invisible platforms to move around undetected.
Naruto's ability to create shadow clones would be extremely useful in Assassin's Creed Origins. He could send clones to scout areas, distract enemies, or even perform coordinated attacks. His Rasengan could be a powerful finishing move against tougher foes. Also, his enhanced physical abilities due to his ninja training would make him a formidable opponent in the world of assassins.
Harry's ability to use magic like the Patronus charm could be combined with Naruto's Rasengan. Maybe Naruto could infuse his chakra into Harry's magic, creating a more powerful and unique attack. Hermione's knowledge of spells could be used to enhance the ninjas' strategies. For example, she could create a spell that would make the ninjas' clones more durable, similar to how they are in the Naruto world but with a magical twist.
If we consider the jutsu in Naruto and the power of the Death Note, some jutsu might be able to protect against the Death Note's power. For instance, a powerful barrier jutsu could prevent the Shinigami from being able to access the area where the person targeted by the Death Note is located. On the other hand, the Death Note's power could be used to manipulate the political situation in the Naruto world. Light Yagami's intelligence combined with the Death Note could make him a very dangerous adversary in the world of ninjas. He could use the Death Note to eliminate key leaders and cause chaos, and then use his wits to take advantage of the situation.
Naruto's shadow clone jutsu could be used in really creative ways when combined with Meliodas' combat style. For example, the clones could surround an enemy while Meliodas attacks from the front, confusing the foe. Also, Naruto's rasengan could potentially be enhanced with Meliodas' demonic energy, creating a more powerful attack.
Naruto's ability to use chakra and Darth Vader's connection to the Force could potentially create a very powerful combination. For example, Naruto could use his chakra to enhance Vader's lightsaber strikes, making them even more deadly. Or Vader could use the Force to help Naruto better control his Nine - Tails chakra.
Naruto characters could bring their unique abilities. For instance, Sasuke with his Sharingan could easily detect hidden enemies or clues in the Assassin's Creed Odyssey environment. His teleportation - like jutsu would also give him an edge in combat and movement. Sakura, with her superhuman strength, could be a formidable fighter in the Odyssey world, perhaps joining the assassins' guild and using her medical ninjutsu to heal wounded assassins.
Well, Naruto's shadow clone jutsu could be really useful in a fight alongside Saitama. The clones could distract enemies while Saitama gets in a powerful punch. And Saitama's super strength could help Naruto in situations where brute force is needed more than ninjutsu. For example, if they had to break through a really thick and magically reinforced wall.
