One interesting concept could be a crossover with a fantasy world like Middle - earth. Imagine an assassin having to navigate the perils of Mordor while still maintaining their creed. Another concept might be a crossover with a historical event not directly related to the main Assassin's Creed timeline, such as the sinking of the Titanic, where assassins could be on board for a secret mission.
Writing a good Assassins Creed crossover fanfic is all about balance. You have to balance the elements of Assassin's Creed, like the hidden blade and the assassin's parkour skills, with the elements of the crossover. Let's say it's a crossover with a detective story. You can't overshadow the detective's investigation skills with the assassin's combat abilities. Also, create believable relationships between the characters. If an assassin teams up with a detective, there should be some initial mistrust that gradually turns into respect and cooperation as they work towards a common goal.
Another great fictional assassin is Beatrix Kiddo, also known as The Bride from 'Kill Bill'. She has been trained in various martial arts and sword fighting techniques. Her quest for revenge showcases her tenacity and ability to take on numerous foes. Despite facing many challenges, she uses her skills to cut through her enemies on her path to vengeance.
The story of Assassin's Creed: Origins is also very good. Bayek's story in ancient Egypt is both personal and tied to the larger Assassin - Templar history. You see the origin of the Assassins as he fights against the Order of the Ancients. The vast and detailed ancient Egyptian world, with its pyramids, deserts, and cities, provides a great backdrop for his journey of vengeance and the discovery of the Creed.
The story in Assassin's Creed: Black Flag is also great. Edward Kenway's tale as a pirate - turned - assassin is full of adventure. You get to sail the high seas, raid ships, and explore islands. His transformation from a self - centered pirate seeking treasure to someone who understands the Assassin's Creed and fights for a greater cause is really interesting. Plus, the naval combat and the pirate lore make it a very immersive story.
Assassin's Creed: Origins has an excellent story. Set in ancient Egypt, it tells the story of Bayek, one of the first assassins. The game does a great job of immersing you in the rich culture and history of Egypt. Bayek's quest for justice against the Order of the Ancients is filled with mystery, action, and exploration. You get to witness the birth of the assassin brotherhood and understand the roots of their ideology.
In my opinion, the story of Assassin's Creed II is one of the best. It follows Ezio Auditore da Firenze's journey from a young nobleman to a master assassin. His revenge story against the Templars who wronged his family is filled with emotion, and the historical backdrop of Renaissance Italy adds a lot of depth. The character development of Ezio throughout the game is really engaging.
In my opinion, the story of Assassin's Creed II is one of the best. It follows Ezio Auditore da Firenze on his journey of revenge and discovery. The setting in Renaissance Italy is beautifully depicted, and Ezio's character development from a young nobleman to a master assassin is engaging. We get to explore iconic Italian cities like Florence, Venice, and Rome. His relationships with other characters, such as his family members and Leonardo da Vinci, add depth to the story.
