I'm not entirely sure if there is a specific 'naruto is escanor fanfic' out there. It depends on the creativity of the fanfic writing community. Some writers might be interested in exploring how Naruto's personality and abilities would interact with Escanor's, perhaps in a scenario where they meet in a different dimension or something. But you'll have to do some searching on the major fanfic platforms to be certain.
Indeed, Escanor's death occurred in the manga. His fate was a significant plot point that had a big impact on the story. It was a poignant moment that added depth to the narrative.
One unique feature is the combination of different power systems. Es canor has his own set of powerful abilities from his original story, and when these are introduced into the Naruto world with its chakra - based powers, it creates a whole new range of possibilities for battles and storylines.
It could be really interesting. Naruto is known for his determination and growth, while Escanor is extremely powerful and has a unique personality. In the fanfic, Naruto might gain some of Escanor's powers like his incredible strength during the day. Maybe Naruto would use these new powers to protect his village in a different way. It could also explore how Naruto's friends in the Hidden Leaf Village would react to his new powers and this new side of him.
One idea could be an Escanor crossover with the Dragon Ball universe. Escanor's incredible strength could be pitted against the Saiyans. Maybe he could have a friendly sparring match with Goku. Another idea is a crossover with the Harry Potter world. Escanor could be a visiting wizard from another realm, showing off his unique powers at Hogwarts and perhaps even helping to defend the school during a dark wizard attack. A third idea is a crossover with the Marvel universe. He could team up with the Avengers, and his unwavering courage and powerful 'Sunshine' ability would make him a valuable asset in battles against supervillains.
One popular theme is the power dynamic between them. Since they both have their own unique powers in their respective series, fanfiction might explore how those powers interact. Another theme could be friendship or rivalry, as they are both strong characters.
In fanfiction, we can see different interpretations of their relationship. Some may focus on a romantic angle, others on a deep friendship. The possibilities are endless. Also, their individual backstories can be intertwined in unique ways in fanfiction. For example, a writer could create a backstory where their fates were connected long before they met in the main story, adding depth and intrigue to their relationship.
I really like 'Escanor and Merlin: A Different Path'. In this fanfiction, the author takes a unique approach to their relationship. Instead of the typical interactions, they are put in a situation where they have to rely on each other in a completely new way. It's full of adventure and the development of their bond is very well - written.
