One possible plot could be that Naruto, with his ninja skills, gets transported to the Assassin Creed world. He might team up with an Assassin, perhaps Ezio. Together, they could use Naruto's chakra - based attacks and the Assassin's stealth and combat skills to take on a common enemy, like a powerful Templar - like figure who is threatening both the ninja world and the Assassin's world.
Well, it could have Naruto characters using Assassin's Creed skills like parkour. For example, Naruto could be running across the rooftops of Konoha in the same fluid way as an Assassin. Maybe Sasuke would be like an assassin with his stealth and quick strikes.
The plot could involve Naruto characters in the Assassin's Creed world. Maybe Naruto himself could be an assassin with his ninja skills. He'd be sneaking around ancient cities, using his shadow clones to distract guards just like assassins use decoys. It would be really cool to see him climb buildings and assassinate targets in a more historical and different setting than the ninja villages.
I think Naruto would be the most interesting. His energetic and determined personality would make for great stories in the Assassin's Creed world. He'd be constantly trying to adapt and use his ninja skills in new ways. His ability to make friends and inspire others would also lead to some interesting interactions with the assassins.
I think Sasuke would be quite interesting. His dark past and thirst for power could be paralleled with some of the Assassin's Creed characters' motives. He could learn new ways to use his skills in the Assassin's Creed world and maybe even find a new purpose.
Maybe there's a hidden Templar plot that has ties to a military case the NCIS is investigating. An Assassin discovers this connection and has to work with the NCIS agents, who are initially skeptical of this person with such strange abilities and knowledge. They gradually learn to trust each other as they uncover the Templar conspiracy together.
How about a crossover with the Star Wars galaxy? The Assassins could find themselves in a far - off planet in the Star Wars universe. They might get involved in the fight between the Jedi and the Sith, using their stealth and combat skills in a whole new environment filled with blasters, lightsabers and strange alien species.
I think Naruto and Altair would make an interesting pair. Naruto is all about exuberance and his belief in the power of friendship and hard work. Altair, on the other hand, is a more stoic and methodical Assassin. Their different personalities would create great character dynamics. Naruto could learn about Altair's strict code of conduct and Altair could be intrigued by Naruto's ability to keep going no matter how tough the situation is.
Well, the plot could be centered around Naruto trying to find a way back to his own world. While in the Assassin's Creed 3 world, he gets caught up in the power struggle between the assassins and the Templars. He could see similarities between the Templars' thirst for power and some of the villains he has faced in his own world. Along the way, he might form bonds with certain characters in the game, like Connor, and together they could face challenges that require both Naruto's chakra - based powers and Connor's assassin skills.
One idea could be that Naruto, with his unique ninja skills, is somehow transported to the world of Assassin's Creed Syndicate. He might mistake the Assassins for a new type of ninja clan. He could then learn their ways of stealth and parkour, while also teaching them some of his jutsu. For example, his shadow clone jutsu could be used to create distractions during assassinations.
