One idea could be a crossover between Fate/Stay Night and another popular anime like Naruto. You could have the Servants from Fate interacting with the ninja world. For example, Saber could face off against Naruto in a battle of ideals. Another idea is a crossover with Harry Potter. Imagine the mages in the Fate universe collaborating with Hogwarts students to fight a common magical threat. Or a crossover with Attack on Titan, where the Servants help the Survey Corps in their fight against the Titans.
To start writing a Fate Series Crossover Fanfiction, you need to do a lot of research on the Fate series and the other universe you're crossing it with. Let's say you're crossing with the Lord of the Rings. You should understand the lore, the races, and the magic systems of both. Then, choose your main characters from each side. You could have Shirou from Fate teaming up with Aragorn. Develop a conflict that makes sense in both worlds, like an evil force that wants to take over both Middle - earth and the Fate world. Write an engaging opening that grabs the reader's attention, perhaps with a dramatic scene from the start.
One idea could be to explore how Hercules' incredible strength affects the Fate universe. Maybe he is summoned as a Servant in a Grail War and his brute force challenges the traditional battle strategies of other Servants. His Twelve Labors could also be incorporated in some way, like each Labor being a trial he has to face within the context of the Fate story.
A third idea is a crossover where the characters from both universes have to team up to face a common enemy. Maybe an ancient evil that threatens both the world of Fate and the DxD world. They would need to combine their powers and strategies, like the devils using their demonic powers along with the Servants' unique abilities.
One great 'Fate Servant Crossover Fanfiction' is 'Fate/Grand Order and the World of Harry Potter'. It combines the magic of the Harry Potter universe with the unique Servants from Fate. The story often has interesting battles where Servants use their powers in the Hogwarts setting. Another one could be the crossovers with the Naruto world. Here, Servants might face off against ninja techniques, creating a whole new dynamic of power clashes.
Another concept is a more comical crossover. Shirou tries to adapt to the different rules and magic in the Fate Apocrypha world. He constantly gets into funny situations as he misunderstands the local customs and magic systems. For example, he tries to cook using Apocrypha - style magic ingredients and chaos ensues.
Archer from the Fate/stay night series is often a popular choice for crossovers. His cool and somewhat aloof personality can create interesting interactions with other servants.
No. Fanfiction with sexual content is generally not appropriate in the Fate series community. The Fate series has a wide range of themes such as heroism, magic, and complex character relationships. It aims to appeal to a broad audience including younger fans. Such adult - themed fanfiction goes against the spirit of the original work and can also make the community environment less friendly and positive.
The exploration of Gilgamesh's character is also a major theme. Many fanfictions use the crossover concept to dig deeper into his personality. They might show a softer side of him that was not fully explored in the original Fate series, or they might further emphasize his pride and arrogance in new and different situations, like when he's in a world full of magic users who don't recognize his kingly status immediately.
The cultural contrast is another aspect. Spartacus comes from a very different historical and cultural background compared to the various characters in the Fate series. This contrast can be used to explore themes like class struggle, morality, and the meaning of heroism in a fresh and exciting way. For instance, how Spartacus views the 'heroic' deeds of some Fate characters who might be from a more aristocratic background.
