A possible plot could involve a group of ponies accidentally traveling to the Assassin's Creed world. They would be out of place and have to adapt quickly. They might team up with an Assassin to stop a powerful enemy. The ponies could use their unique magical abilities, like Rainbow Dash's speed or Fluttershy's ability to communicate with animals, to help the Assassin in their quest. And in return, the Assassin could teach the ponies about their history and fighting techniques.
First, you need to decide on the main characters from both universes that will be involved. Then, think about the setting. Will it be mostly in Equestria or in the Assassin's Creed world? For example, if it's in Equestria, how will the Assassin's Creed elements fit in? Maybe there are secret Assassin guilds hidden among the ponies. Next, create a conflict that requires both the ponies' magic and the Assassins' skills to solve. It could be something like a dark magic that is threatening both worlds.
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.
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.
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 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.
Common themes in Assassin's Creed crossover fanfic often include identity. The assassins from Assassin's Creed enter a new world and have to re - evaluate who they are and what their purpose is. Another theme is cooperation or conflict. In a crossover with a superhero universe, they might either team up with the heroes to fight a common enemy or be in conflict with them due to different ideologies. And there's always the theme of discovery. When they cross into a new and unknown world, like the world of Studio Ghibli's movies, they discover new ways of life, new values, and new forms of magic or technology.
One idea could be a crossover with Pirates of the Caribbean. The Assassin could team up with Jack Sparrow to find a hidden treasure that is also related to an ancient Piece of Eden. They'd face challenges like sea monsters and rival pirates.
One possible plot could be that the Assassins discover the wizarding world. They might team up with Harry Potter and his friends to fight against a common enemy, like a dark wizard who has ties to the Templars. The Assassins could use their skills in stealth and combat, while the wizards use magic.
To start an Assassin's Creed crossover fanfiction, begin by picking the other franchise you want to cross it with. If it's 'Avatar: The Last Airbender', study the bending elements and the different nations. For Assassin's Creed, understand the creed and the Assassin's skills. Think about how the two worlds will interact. For instance, an Assassin could end up in the world of Avatar and learn bending. You can start writing by setting the scene, perhaps with the Assassin arriving in the Fire Nation through some strange portal. Describe the Assassin's confusion and their first encounter with the Firebenders. This will draw the reader in and start the story off on an interesting foot.
