Luis Nuñez de Castro Torres – Luis NCT for short – grew up in Valencia, Spain, reading comics of all kinds on the Mediterranean beachfront. He made comics and fanzines in high school, eventually studying fine arts before becoming a freelance artist. He has worked as a concept designer for video games and film, but his passion will always be comic books. His first long-form comic book project was Sleepers, a post-apocalyptic sci-fi tale about a world ruined by giant robots, an open homage to his love of the genre. This gave way to his second long-form solo project, WAHCOMMO, and his love for high-fantasy.

His most prominent work in the United States has been as a colorist with artist Jason Shawn Alexander on the Image Comics series Empty Zone, the Vertigo series Frostbite, and a three-issue run on Spawn. He is currently coloring the critically acclaimed Image Comics series Killadelphia. He just published the sequel to WAHCOMMO, Kaya.
