Good writing style also matters a great deal. The use of vivid language to describe the world of Fate, their interactions, and their emotions can really bring the story to life. If the writer can make you feel the tension, the love, or the respect between Gilgamesh and Siduri, then it's likely to be a great fanfic.

The contrast between their characters. Arturia is often portrayed as noble and self - sacrificing, while Gilgamesh is arrogant and self - assured. This creates a dynamic that can lead to interesting stories.
In a good Saber x Gilgamesh fanfic, the plot is key. It could be a story that explores their relationship in a new and interesting way. Maybe it's set in an alternate universe where they have different circumstances. The chemistry between them needs to be palpable. It should also have a good balance of dialogue and description. Dialogue can bring out their personalities and the dynamic between them, while description sets the scene and mood. And of course, a touch of creativity, like adding unique magical elements or new backstories for them, can make the fanfic really stand out.
One reason is Gilgamesh himself. He's a complex and powerful character in the Fate series. His arrogance and god - like power make him interesting to write about. Writers can explore different sides of him in fanfiction, like his past, his relationships, or his view on the modern world.
The popularity of 'gilgamesh x enkidu fanfic' might be due to the unique nature of their relationship in the original story. It's a relationship full of contrasts and yet deep connection. Fans are drawn to exploring more about it.
I really like 'Gilgamesh and Saber: An Alternate Path'. It takes a different route from the original story. Here, Gilgamesh realizes Saber's worth much earlier and tries to court her in his own haughty way. It's an interesting take on their relationship and how it could have developed.
Good character development is key. The writer should show how Shirou and Fem Gilgamesh grow and change because of their relationship. Also, an interesting plot that doesn't just rely on their romance but also has some action or mystery. For example, they could be on a quest together to find a powerful relic.
One common theme is the clash of their personalities. Gilgamesh is proud and haughty, while Mordred is rebellious. Their interactions often involve power struggles and attempts to outwit each other.
The different personalities. Shirou is often seen as selfless and idealistic, while Fem Gilgamesh is likely to be proud and powerful. Their interaction can lead to a lot of drama and character development.
Well, 'Female Gilgamesh's Reign' is another one. In this fanfic, female Gilgamesh is depicted as a very dominant and powerful figure. The story is full of action and also shows her more human side, like her moments of self - doubt and how she overcomes them. It's really engaging for fans of the Fate series who want to see a different take on Gilgamesh.
