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.
When looking at the battle between Shirou and Kotomine in the visual novel, we need to consider their character development up to that point. Shirou has grown through his experiences and his relationships with other characters. This growth affects how he approaches the fight. Kotomine, with his long - standing plans and knowledge, presents a formidable opponent. Shirou's tenacity and the power he has acquired through his journey are crucial in this battle. The battle is also a display of the visual novel's complex storytelling, as it ties in with the overall themes of the story, such as the nature of heroism and sacrifice.
In this fanfiction, it could start with an experiment in the magical research of both universes. Harry Potter, while exploring new magic, accidentally creates a portal to the world of Kotomine. Finding the young Kotomine in a difficult situation, Harry decides to stay and help him. As time passes, Harry imparts his knowledge of friendship, love, and the power of good magic to Kotomine. Their relationship grows, and they face various threats together, including enemies from both the Harry Potter and Fate universes who see their relationship as a threat to the established order. Harry's role as a father figure would be central to Kotomine's development, and they would embark on a journey of self - discovery and adventure.
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.
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.
It's hard to say who is more likely to win. Shirou has his strong will and growth throughout the story. But Kotomine is very cunning and has a lot of knowledge and power. It could really go either way depending on how the story unfolds and the specific circumstances in the visual novel.
First, understand the characters well. Know Shirou's journey of self - discovery and his heroic ideals, and also understand Kotomine's motives and his rather dark view of the world. This will help you write their interactions more authentically. For example, when they have a conversation, you can make it feel natural based on what we know about their personalities.
I'm not sure if there is exactly a fanfiction with the title 'Harry Potter is father Kotomine'. There are a vast number of fanfictions out there in the world of Harry Potter and Fate series crossovers, but this specific one might be quite rare or might exist only in a very niche corner of the fanfiction community. It could potentially be a very creative and out - of - the - box idea where the author tries to blend the two very different universes in a way that makes Harry Potter somehow related to Kotomine in a father - son relationship. But without actually finding it, it's hard to say more about its specific plot or how well - written it could be.
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.
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.
