In many fanfics, Female Shirou often retains the strong - willed nature of the original Shirou. However, she may display more emotional vulnerability due to the different social expectations placed on female characters. For example, she might struggle more openly with her self - identity.
In these crossovers, the theme of growth is quite common. Shirou starts as his normal self but through his experiences in the new world, he grows as a character. For example, in a crossover with the 'Naruto' world, he may learn new combat techniques and also gain more understanding of different kinds of power. Another theme is the exploration of new power dynamics. How his power compares to the powers in the new world, like if he's in the 'Bleach' universe, how his abilities stack up against Soul Reapers. And the theme of moral dilemmas also exists. He may face situations where the moral code of the new world challenges his own.
There are also fanfictions that explore Sakura's darker side in relation to Shirou. Given her connection to the Grail and the secrets she holds, she could be a more complex and dangerous figure. However, Shirou's love for her might be the thing that tames or redeems her in these stories.
Another angle in fanfiction could be the exploration of their character growth through their relationship. Shirou, who starts off with a rather idealistic view of heroism, might learn more about the reality of sacrifice and love from Sakura. Sakura, on the other hand, could gain more confidence and a sense of self - worth through Shirou's unwavering support. This mutual growth can be a fascinating aspect to explore in fanfiction.
One common theme is the exploration of their different personalities coming together in a marriage. For example, Artoria's noble and sometimes aloof nature with Shirou's self - sacrificing and determined personality. Another theme could be how they deal with the challenges of their new relationship in a world full of magical and dangerous elements.
One popular Fate Stay Night Female Shirou fanfic is 'The Adventures of Female Shirou'. It offers a fresh take on the story with unique plot twists. Another one could be 'Female Shirou's Journey' which delves deep into her character development in an alternate universe. There are also some on fanfic platforms like Archive of Our Own that are worth exploring.
Power and its consequences are common themes. Since Shirou has certain powers in the Fate Kaleid universe, fanfictions often deal with how he uses them, and what happens when he misuses or overuses them. Also, the theme of sacrifice is there. Shirou is a character known for his self - sacrificing nature, and this is often emphasized in fanfictions.
One common theme is the exploration of Archer's complex personality. The OC often serves as a catalyst for this exploration. Another theme is the power dynamic between Archer and the OC, especially if the OC is a mage or has some special ability. Also, there's often a theme of redemption or self - discovery for Archer through his interactions with the OC.
He could be a wild card. Maybe he has different motives from his original role. For example, he might be trying to change certain events that he regretted in his own timeline.
One popular one could be 'Archer's New Adventure in a Crossover World'. It often features Archer in unexpected situations in a crossover setting, with interesting character interactions.
