A reaction fanfiction in Fate Apocrypha could explore the characters' responses to various events. For example, how the Servants react to unexpected twists in the Holy Grail War. It might be interesting to see how characters like Siegfried or Mordred would react to a rule change in the war.
EMIYA often plays a key role in Fate Apocrypha fanfic. He can be a protagonist, guiding the story with his unique set of skills and experiences. His combat abilities and strategic thinking make him a formidable force in any fan - created scenario.
In Fate Apocrypha fanfic, EMIYA might be given new backstories or motives. This is because fanfic authors have the freedom to expand on the existing lore. They can delve deeper into his past as a hero, perhaps exploring his time as a hero before he became a Counter Guardian. This can add new layers to his character and make him more complex and appealing to readers.
An OC (Original Character) in Fate Apocrypha fanfiction can bring fresh perspectives. It allows fans to explore uncharted territories within the Fate Apocrypha universe. For example, an OC could be a new Servant with a unique backstory and abilities, which might interact with the existing characters in interesting ways. Fanfiction writers often use OCs to fill in the gaps they feel exist in the original story or to create their own unique story arcs that still fit within the overall theme and lore of Fate Apocrypha.
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.
One popular trope is the 'hidden power' trope. The OC might start off as an unassuming character but gradually reveals a powerful and unique ability that changes the course of the Holy Grail War. Another is the 'love interest' trope, where the OC becomes romantically involved with one of the canon characters, adding a new layer of drama to the story.
Naruto's character would fit in quite uniquely. His boisterous and positive personality would be a contrast to some of the more solemn characters in Fate Apocrypha. His ability to make friends easily could lead to some interesting alliances. For example, he might befriend some of the more morally ambiguous Servants and sway them towards a more positive path.
The main characters in Fate Apocrypha light novels are quite diverse. Sieg is an interesting protagonist as he defies the expectations of a typical character in the Fate series. He is not a traditional hero at first but evolves into one. Jeanne d'Arc is a well - known historical figure and her presence as Ruler gives the story a moral compass. Astolfo is a fan - favorite due to his fun - loving and powerful nature. Mordred, being King Arthur's son, has a lot of internal conflict and her actions drive the story forward in many ways. And Shirou Kotomine is a character full of mystery and his actions often have far - reaching consequences in the plot.
Another interesting concept is to create an alternate ending. Maybe the two factions end up working together against a greater threat that was hidden all along, like an ancient evil that awakens during their battle.
