Kakashi would be an interesting crossover character. He's already a master of stealth and combat in the Naruto world. In Assassin's Creed, he could easily adapt to their methods. His Sharingan would allow him to copy the assassins' moves and improve upon them. He could also use his ninja tools, like his kunai and shuriken, in combination with the assassins' weapons to create a unique fighting style.
I think Sasuke would be really interesting. He has that brooding and powerful nature. In the Assassin's Creed world, he could be a very effective assassin. His Sharingan would give him an edge in combat and his ability to quickly analyze situations would be useful for assassinations. He could also learn from the assassins' techniques and incorporate them into his own fighting style.
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.
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.
Harry Potter and Altair would be a great combination. Harry's sense of justice and Altair's Assassin skills would make for an exciting duo. They could learn from each other, with Altair teaching Harry about stealth and combat techniques from the Assassin's Creed world, and Harry showing Altair the power of magic.
I think Ezio Auditore would be a great addition. He's a beloved character from the Assassin's Creed series. His skills and charisma would make for an interesting interaction with Kassandra or Alexios. They could learn from each other's experiences and combat styles. Another interesting character could be Lara Croft. Her knowledge of archaeology and survival skills would blend well with the world of Assassin's Creed Odyssey. She could join forces with the assassin to explore ancient tombs and uncover hidden secrets.
Aiden Pearce from Watch Dogs and Ezio Auditore from Assassin's Creed would make an interesting pair. Aiden's hacking skills combined with Ezio's combat and stealth expertise would create a dynamic duo. Ezio could use his knowledge of historical architecture and secret passages, which could be translated into modern - day knowledge with Aiden's hacking to access restricted areas in the city.
I think Naruto himself would be really interesting. His positive and determined attitude would contrast with the often darker and more complex world of FMA. He could bring his unique brand of ninja spirit and try to make friends with the characters in FMA. His ability to use chakra and his various jutsu would also create some really cool interactions when faced with the alchemists and their powers.
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.
One of the interesting aspects is how the characters from Naruto would adapt to the Assassin's Creed lore. Like how would Naruto deal with the Templar - Assassin conflict? And how would the values of the ninja, such as loyalty and sacrifice, interact with the Assassin's Creed ideals of freedom and justice? It's also fascinating to see how the different settings, like the rooftops in Assassin's Creed cities and the forests in Naruto, are merged together. This creates a whole new environment for the characters to explore and interact in.
A cool plot could be that the Templars in the Assassin's Creed world somehow get hold of some ninjutsu scrolls. They start using these to create an army of super - soldiers. The Naruto characters then team up with the assassins to stop the Templars. Naruto could use his Rasengan against the Templars' new warriors, while Altair could use his eagle vision to spot their weaknesses. Together, they could form a unique combat strategy that combines the best of both worlds.
