How can one write a good Shirou Kotomine crossover fanfiction?

There's a fanfiction called 'Kotomine and Shirou: United Front'. In this one, they are forced to team up against a common enemy that neither could face alone. The story delves deep into their relationship, starting from their initial distrust and gradually building towards a mutual respect and understanding. It's a great read for those who like character - development - focused fanfictions.

A common concept is a power - up or alternate power - set for both characters in the crossover. Shirou might gain some of Kotomine's knowledge of the Grail or his combat skills, while Kotomine could inherit Shirou's ability to project weapons in a new and unexpected way. This could change the power dynamics in battles and the overall plot of the fanfiction.

The popularity of Kotomine Shirou crossover fanfiction lies in the contrast between the two characters. Kotomine is often seen as a complex and morally ambiguous character, while Shirou is more of an idealist. When they are brought together in a crossover, it creates a lot of interesting dynamics that fans love to explore.

Another interesting one is 'Under the Moonlit Alter'. This story focuses on the more emotional side of their relationship. It shows how their bond develops over time, starting from a place of mutual suspicion to a deep and abiding connection. The author does a great job of describing their internal thoughts and feelings as they navigate their relationship.

To write good crossover fanfiction, start by researching the source materials thoroughly. If it's a crossover between 'Game of Thrones' and 'Narnia', study the politics, cultures, and magic in both. Then, find a common theme or goal for the characters from different worlds. Maybe they're all fighting against an ultimate evil. Develop the characters' relationships in a believable way. The characters from 'Game of Thrones' might be skeptical of the talking animals in Narnia at first. Also, use vivid descriptions to bring the combined world to life. Describe how the Iron Throne would look in the middle of Narnia. And don't be afraid to break some rules, but do it in a way that still makes sense within the context of the story.

You can start by looking on fanfiction.net. It has a large collection of Fate - related fanfictions, and you're likely to find some good ones about Shirou Kotomine and Saber Alter there. Just use the search function and type in the relevant keywords.

To write a good Vergil crossover fanfiction, it's important to do your research on both Vergil and the other element of the crossover. If it's a crossover with a book series, read up on the lore and the characters. When writing, start with a strong hook to draw readers in. Maybe it's a mysterious encounter between Vergil and the other character. Develop the relationship between the characters gradually. Show how they influence each other. And don't forget to add some action scenes that showcase Vergil's skills in a new and exciting context. Use vivid descriptions to make the story come alive.

First, know your source materials well. You need to be familiar with the characters, settings, and rules of the different fictional universes you're crossing over. Then, don't be afraid to break the rules a bit. Since it's chaotic, let your imagination run wild. For example, if you're crossing 'Star Wars' and 'The Matrix', think about how the Force might interact with the Matrix's digital world. Also, focus on the characters' reactions to this new and crazy situation. Their confusion or quick adaptation can make for great storytelling.

First, know the character of Toshiro well. Understand his personality, his powers, and his backstory from Bleach. Then, choose the other universe or character to cross over with carefully. Make sure there are elements that can create interesting conflicts or alliances. For example, if it's a crossover with a superhero universe, think about how Toshiro's powers would fare against superhuman strength or the ability to fly.

First, know the character of Garen well. His honor, his loyalty to Demacia, and his combat style are key aspects. Then, research the other universe you want to crossover with. If it's a 'Star Wars' crossover, understand the Force, the different planets, and the various species. Next, create an interesting plot that brings out the best (or worst) in Garen in this new context. For example, if he's in a 'Game of Thrones' - like world, how does his sense of honor play in a world full of political intrigue?
