Oral tradition: The story spread in rural Mexico along the lonely roads at night, giving it an eerie authenticity.
Pop culture adaptations: For example the 2018 animated film La Leyenda del Charro Negro made the character accessible to younger generations.
Symbolic power: Because the legend touches universal themes (temptation, doom, morality) it continues to resonate.
Visual imagery: The striking image of a sleek black horse, an elegant charro suit and the night-road setting makes for memorable storytelling.
