One idea could be that Naruto characters are summoned as Servants in FGO. For example, Naruto himself could be a Berserker with his never - give - up attitude and powerful chakra being translated into high - level stats. Sasuke could be an Assassin, using his Sharingan to detect and strike enemies stealthily.
Naruto characters could fit into the FGO lore in various ways. For instance, Naruto's world has different levels of power and abilities, much like the Servants in FGO. His ability to use chakra could be seen as a form of magic in the FGO universe. So, a Naruto character like Kakashi could be a Caster, using his wide knowledge of jutsus as spells.
One idea could be a crossover where Naruto characters are summoned as Servants in FGO. For example, Naruto himself could be a Berserker class Servant with his incredible chakra and determination. Another idea is a story where the FGO Master has to team up with Naruto characters to defeat a common enemy that threatens both the FGO universe and the Naruto world. Maybe it could be an evil mage in FGO who is also trying to harness the power of the tailed beasts in the Naruto world.
Another theme might be the alternate universe scenarios. Fanfic writers often use the idea of Morgan and 'lemon' elements to create unique storylines that deviate from the official FGO lore. They could place Morgan in unexpected situations related to love or passion, and how she copes with them.
One interesting aspect is the character mash - up. You get to see how characters like Saber from FGO would interact with Reimu from Touhou. Their different personalities and powers create unique dynamics.
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.
The plot could be really interesting. Imagine Naruto, with his strong will and determination, being reborn as the first Hassan in the FGO world. He would have to learn the rules and magic of this new world. His ninja training and experiences in the Naruto world would give him an edge. He might encounter some FGO characters who are initially skeptical of him because he's so different. But as they see his power and his unique abilities like his Rasengan, they start to accept him. And then they all team up to face powerful foes that are emerging in the FGO world, and Naruto uses his Naruto - esque strategies and skills to turn the tide of the battles.
FGO isn't a typical visual novel. It has more gameplay mechanics and character-building features. The story is presented along with battles and strategic decisions.
There's also 'FGO - Touhou: The Meeting of Worlds'. In this fanfic, the plot often involves the Servants from FGO interacting with the various characters from Touhou in unexpected ways. For example, some of the strategic battles in FGO are influenced by the magical powers and unique fighting styles of the Touhou characters.
