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.
Well, when writing a 'Fate Servant Crossover Fanfiction', research is key. If you're crossing with the Marvel universe, study the abilities and backstories of both the Servants and the Marvel characters. Then, create a conflict that can only be resolved by the combined efforts of both sides. Maybe a powerful villain from the Fate world has teamed up with a Marvel villain, and the Servants and the Avengers have to work together. Additionally, add some emotional depth to the story. Maybe a Servant has a past connection to a Marvel character, which adds more layers to their interactions.
Yes, there are likely some Fate fanfictions out there where Naruto is depicted as a servant. The concept of crossing over Naruto with the Fate universe allows for interesting combinations. Writers might explore how Naruto's unique abilities, like his shadow clones or Rasengan, would function within the framework of the Holy Grail War and the servant system in Fate.
One possibility could be a story where a character from Harry Potter becomes a servant in the Fate universe. For example, Harry himself could be summoned as a servant. His magic from the Potter world might interact in interesting ways with the rules of the Fate system. He could use spells like Expelliarmus against other servants, and his ability to resist the Dark Arts might give him an edge in battles.
One common theme is the struggle for power. The self - insert often has to deal with the power dynamics in the Fate universe, whether it's competing with other Masters or trying to control powerful Servants. Another theme is self - discovery. As the SI is in a new and strange world, they learn more about themselves and their capabilities.
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.
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.
There are quite a few 'Fate Servant SI Fanfiction' out there. 'Lost in the Fate World' is a story that really stands out. The SI character is lost in the complex Fate world and has to navigate through different Servant alliances and conflicts. It does a great job of world - building and character development. And 'Fate's Unexpected Guest' is also a good read, with the SI having some unexpected interactions with famous Servants, creating a lot of interesting plot twists.
