Here's why:
* Origin: Batman's origin story is rooted in realism and trauma, not magical elements. He is a human who chooses to fight crime after witnessing his parents' murder.
* World: Batman's universe, Gotham City, is a gritty, urban setting with realistic problems.
* Powers: Batman doesn't possess magical powers. His abilities come from technology, martial arts, and strategic brilliance.
* Genre: Batman stories belong to the superhero and crime fiction genres, not fairy tales.
While Batman may have some elements that could be considered "fantastic" (like his gadgets and the dark, gothic atmosphere of Gotham), the core of his character and his stories is based in a grounded reality.
Fairy tales, on the other hand, typically involve magical elements, fantastical creatures, and moral lessons often expressed through allegory.
