Agustin "Gus" Guerrero, also known as El Gato Negro, is a fictional character and comic book superhero created by Richard Dominguez and published by Azteca Productions.

Operating in South Texas, Agustin first donned the alter ego of El Gato Negro in order to form a successful career in Lucha Libre in the early 1950s.

Richard Dominguez first conceived El Gato Negro sometime in the mid-to-late '80s and originally planned to showcase the character in a largely Latino superhero group dubbed Team Tejas.

"[2] El Gato Negro's visual design was largely influenced by the Lucha Libre traditions as well as Dominguez's favorite comic book and pulp superheroes.

Included among them was Lee Falks' comic strip superhero the Phantom, a character who is believed to be immortal but in reality, is descended from twenty previous generations of crime-fighters who all adopt the same persona.

[3] Agustin made his first published appearance in El Gato Negro #1 (Oct. 1993) as a major supporting character in the three part story-arc, "Unknown Passing, Unforgettable Return".

Separated from his group while on a raid, he became lost in the harsh jungle only to encounter an exiled Japanese warrior and assassin known as Kuro Neko ("黒い猫" - "The Black Cat").

Recognizing the recurring cat motif in his life, Agustin chose the identity of El Gato Negro, promising to bring bad luck to his opponents.

Son of the successful businessman and drug lord Ignacio Ochoa, an enemy Agustin had faced early in his career, El Graduado planned to take his father's place amongst a criminal organization known as the Annulus.

As of January 2016, Richard Dominguez is currently working with writer-turned-director Michael S. Moore in directing and filming a live-action short-film adaptation titled El Gato Negro: Prey.
