 Growing tired of the increasing crime rate in the Lower Rio Grande Valley and haunted by the murder of his friend Mario, Francisco continues the legacy of El Gato Negro, spending his nights fighting against crime.This version often receives comparison to Batman, which is in fact one of the character's many influences.The El Gato Negro characters were created by comic book artist and writer Richard Dominguez, both making their first published appearance in "El Gato Negro" #1 (October 1993) published under Dominguez's own Azteca Productions imprint.
