Jesús Barrero was a prolific Mexican voice actor renowned for his extensive work in the dubbing of anime, animation, and live-action film and television for the Latin American Spanish market. Born José Jesús Barrero Andrade on July 26, 1958, in Mexico City, he began his artistic training at the age of nine at the Instituto Andrés Soler, the acting school of Mexico's National Association of Actors. His career in dubbing and acting spanned over four decades, starting in the late 1960s and continuing until his passing. He studied psychology but ultimately dedicated his professional life to his talent for voice acting.

Barrero's voice became iconic for a generation of viewers through his leading roles in numerous anime series. He is most famously recognized as the definitive Spanish voice of Seiya in the immensely popular series Saint Seiya (known as Los Caballeros del Zodiaco), a role he reprised for subsequent installments including Saint Seiya: The Hades Chapter - Sanctuary, Saint Seiya: The Hades Chapter - Elysion, the film Saint Seiya: Legend of Sanctuary, and the series Saint Seiya: Omega. His other foundational anime roles included providing the voice of Koji Kabuto in Mazinger Z, the title character Meisuke Nueno (Nube) in Jigoku Sensei Nube, and Rick Hunter in the first Latin American Spanish dub of Robotech.

His portfolio extended across a wide variety of anime titles and genres. He voiced the protagonist Melos in the film Hashire Melos!. In the Street Fighter II: The Animated Movie, he provided the voice for the character Ryu in the DVD version of the Latin American Spanish dub. He also lent his voice to characters such as Shiro Mizunuma in the Studio Ghibli film From Up On Poppy Hill, Toby in the 1990s series Little Lulu, Febo (Hiroshi Shiba) in Kotetsu Zieg, Locke in Locke the Superman, Rex in Magnos The Robot, and Aladdin in the anime film Aladdin and the Wonderful Lamp. In addition to these, his anime filmography included roles in Digimon Tamers, Digimon Frontier, Eyeshield 21, Gintama, and Akira.

Beyond anime, Barrero's voice was highly recognizable for his work in major animated and live-action franchises. He was the long-time Spanish voice of Rex in the Toy Story film series and Flik in A Bug's Life, as well as Kuzco in The Emperor's New Groove and its related projects, and Banzai in The Lion King and its sequels and spin-offs. In live-action dubbing, he was particularly noted for being the primary voice of actors Jason Statham and Paul Walker in many of their films, and for dubbing Luke Skywalker (Mark Hamill) in the Star Wars saga, including Star Wars: The Force Awakens, his last film role. His work also encompassed dubbing for actors such as Tom Hanks, Bruce Campbell, and River Phoenix in various films.

Throughout his career, Barrero frequently collaborated with a consistent group of fellow voice actors, forming an ensemble that defined the sound of Latin American dubbing for decades. This included frequent work with colleagues such as Mario Castañeda, Eduardo Garza, and Ricardo Mendoza, among others, particularly in series like Saint Seiya and Dragon Ball. His significant contributions to the art of dubbing left a lasting legacy on the industry in Mexico and throughout Latin America. Jesús Barrero passed away on February 16, 2016, in Mexico City at the age of 57 after a battle with lung cancer.
