Some fanfictions pair Azrael with a human who has a special gift, like being able to see the future or communicate with spirits. This human can act as a guide for Azrael in the human world, while Azrael protects the human from the more dangerous aspects of the supernatural world.
Azrael in 'Supernatural' fanfiction is often depicted as an angel of death. In the context of the show and related fanfictions, Azrael has powers related to death and the afterlife. They are usually a very powerful and mysterious character.
One key element is his power. He's extremely strong, which drives a lot of the story. Another is his ambition. He wants to be on top. Also, his battles with other powerful characters are important parts of his story.
In the world of fanfiction, the possibilities are endless. So, it's entirely possible that Naruto is one of the 10 Espada in a particular fanfic. Fanfic writers are known for their creativity in mixing and matching different elements from various shows and mangas. They could take Naruto's character and place him within the Espada hierarchy, perhaps giving him a new look, new powers, and new relationships within that framework. This can create a whole new story that both Naruto and Bleach fans might find interesting.
It could lead to some really interesting plot twists. Ichigo's powers and nature might interact with the Espada's dynamics in unexpected ways, creating a whole new story arc.
A lot of 'azrael supernatural fanfic' also deals with the concept of fate. Since Azrael is often associated with death in some ways, there are stories that explore how his actions impact the fates of the characters in the Supernatural world. For example, how his decisions might change the course of the Winchester brothers' lives. It's really interesting to see how different authors play with this idea.
Another common theme is adaptation. When the Espada enter a new and different setting in these fanfictions, they have to adapt to new rules, cultures, or ways of life. It can be really interesting to see how they change or resist change. Like in a crossover where they enter a world with strict moral codes.
