Another interesting concept could be a fusion of the Hidden Leaf Village and an Assassin's Creed Brotherhood. The ninjas could adopt some of the assassin's stealth and parkour abilities, and together they could fight a common enemy that threatens both their worlds.
One interesting idea could be exploring the backstory of a minor character in the game. For example, you could write about the early days of a random assassin in training, their struggles, and how they overcame them. Another idea is to create an alternate universe where the Templars and Assassins have a different kind of relationship, like a truce that changes the whole dynamic of the story. Or you could focus on a specific historical event that was only briefly touched upon in the games and expand it from an Assassin's Creed perspective.
One idea could be Naruto being transported to the world of Assassin's Creed Syndicate. He could use his ninja skills, like shadow clones, in the context of the Assassin's Creed world. For example, his clones could be used to distract the templars while he sneaks in to steal an important artifact.
One idea could be that Naruto, with his ninja skills, somehow gets transported into the Assassin's Creed Rogue world. He might mistake the Assassins for some new type of ninja clan. He could then use his unique jutsu, like the Shadow Clone Jutsu, in battles against the Templars. For example, he creates a horde of clones to distract the enemy while he sneaks up on them like an Assassin.
One idea could be that Naruto, with his ninja skills, gets transported to the Assassin's Creed world. He teams up with the Assassins and in the process, attracts a harem of both ninja and Assassin women. They are drawn to his unique abilities and his unwavering determination.
A possible plot could involve an Assassin from Assassin's Creed Origins finding a way into the Naruto world. He discovers the chakra system and tries to incorporate it into his assassin skills. Naruto and his friends become intrigued by this strange visitor and his different fighting style. They team up to stop a group of rogue ninjas who are trying to steal ancient artifacts from both worlds.
A great plot for Assassin's Creed 3 fanfiction could be an alternate ending. For example, what if Connor had managed to convince Haytham to join the Assassins? This would completely change the story's dynamic. Or, a story could be written about Connor's adventures in a different part of the world, like exploring Europe during the same time period. He could encounter new Assassins or Templars there and have to adapt his skills. Also, a fanfiction could center around the impact of Connor's actions on the future of the Assassin Brotherhood in America.
A great Assassin's Creed crossover fanfiction idea is to cross it with 'Game of Thrones'. Picture an Assassin in Westeros, trying to navigate the complex web of political intrigue and assassination plots that are already rife in that world. They could be hired by different houses to carry out assassinations or be on a mission to uncover some dark secrets. Another interesting one could be a crossover with 'Cyberpunk 2077'. An Assassin in a high - tech future world, using their traditional skills along with new - age technology to take out targets in the neon - lit streets of Night City.
One idea could be creating an OC who is a descendant of a lesser - known historical figure involved in the Assassin - Templar conflict. For example, an OC descended from a local resistance leader during a particular era. Another idea is to have an OC with a unique skill set, like being able to communicate with animals which gives them an edge in stealth missions. Or an OC who is a double agent, initially thought to be a Templar but is actually an Assassin with a very complex backstory.
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.
One idea could be that Naruto, with his ninja skills, gets transported to the Assassin's Creed world. He might mistake the Assassins for a new type of ninja. He could then start learning their ways, like using the hidden blade in combination with his own jutsu. Another plot could involve Naruto teaming up with an Assassin to take down a powerful enemy that is causing chaos in both the Naruto universe and the Assassin's Creed universe.
