I really liked 'Haikyuu at Chaldea'. In this fanfiction, the Haikyuu characters end up in the FGO world. The author does a great job of showing how the Haikyuu team members adapt to the strange new environment filled with magic and Servants. They bring their own team spirit and determination, which has an impact on the events in the FGO world.
The appeal lies in the contrast of the two universes. FGO has a complex, magical world full of powerful Servants, while Haikyuu is all about high - energy volleyball and the spirit of a team. When combined, it creates a really unique and interesting dynamic. For example, seeing a Servant from FGO trying to understand the rules of volleyball in a Haikyuu - style court is both funny and engaging.
Well, a lot of fgo crossover fanfiction involves different historical periods colliding. Say, a crossover with the Roman Empire era and the modern day in the fgo world. Servants from different eras teaming up or facing off against each other can create really engaging storylines. Also, crossovers with other JRPGs like 'Final Fantasy' often bring in unique magic systems and character designs that add a whole new dimension to the fgo fanfiction.
One idea could be a Haikyuu and My Hero Academia crossover. The volleyball players could suddenly discover they have quirks. For example, Hinata might have a quirk that makes him jump even higher, like a super - powered leg spring. It would add a whole new dynamic to their games and rivalries.
To start writing fgo crossover fanfiction, you need to have a good understanding of the fgo lore and the thing you want to cross it with. Do your research on both. Then, create an interesting plot. Maybe start with a small event that brings the two worlds together, like a strange rift opening between the fgo world and the world of 'The Legend of Zelda'. And then build the story from there, focusing on how the characters adapt and react.
You should also focus on the characters. Figure out how they would react to the new elements from the other fandom. In a Haikyuu and One Piece crossover, the volleyball players might be amazed by the Devil Fruits and the strange powers they give. And Luffy might be interested in their intense volleyball matches. Write down all these ideas before starting to write the actual story.
One idea could be a beach volleyball tournament where the characters from Haikyuu and Free come together. The Haikyuu players' skills in teamwork and strategy could blend with the Free characters' swimming abilities as they adapt to the new sport. Another could be a training camp where they all learn from each other's athletic disciplines.
One popular theme is the crossover between FGO and other well - known franchises like 'Type - Moon' series. For example, characters from different 'Type - Moon' works interact in unexpected ways. Another theme could be time - travel crossovers within the FGO universe itself, where Servants from different eras are brought together in a unique scenario. Also, crossovers with classic literature or mythology are quite common, as FGO already has a basis in many mythologies. Servants from different mythologies interact with modern - day FGO characters, creating interesting storylines.
One great 'Haikyuu! Bnha Crossover Fanfic' is 'Volleyball Heroes'. It combines the unique powers from Bnha with the exciting volleyball matches of Haikyuu. The characters' interactions are really interesting, like when Midoriya tries to learn volleyball techniques from Hinata. It's a fresh take on both universes.
First, you need to be familiar with both universes. Know the characters, their personalities, and the rules of each world. For example, in Haikyuu, understand the volleyball strategies and the different teams. In Bnha, know the quirks and how they work. Then, think of an interesting concept for the crossover. Maybe it could be about the Bnha characters joining a volleyball tournament in the Haikyuu world.
