Roberto Sen was the artistic name of Mexican actor Roberto Espriú Sen, who built a prolific career spanning over six decades in voice dubbing, television, and film. Born on September 22, 1946, in Mexico City, he was the son of actors Roberto Espriú and Maruja Sen, which placed him in an artistic environment from a young age. His first foray into dubbing occurred during his childhood in the 1950s with the film Viaje a la Prehistoria. He passed away on August 5 or 6, 2024, at the age of 77, an event confirmed by Mexico's Asociación Nacional de Actores.

Sen is perhaps most widely recognized for his extensive and enduring contributions to the Dragon Ball franchise in Latin American Spanish. He was the first voice of the boisterous martial artist Mr. Satán in Dragon Ball Z, a role he performed from episode 173 through 219 during the Cell Games saga. His connection to the series, however, began even earlier; he voiced the villainous Commander Red and General White in the original Dragon Ball series. He also took on the role of the Three-Star Dragon in Dragon Ball GT. After a period of semi-retirement from dubbing, Sen made a notable return to voice a character he had portrayed before: Paragus, the father of Broly. He first voiced Paragus in the film Dragon Ball Z: The Legendary Super Saiyan and later reprised the role for the 2018 feature film Dragon Ball Super: Broly, marking a significant and celebrated comeback for the actor.

Beyond the world of Dragon Ball, Roberto Sen's voice was featured in a wide array of animated projects and dubbed films. In anime, his credits include roles in Digimon 02 as Chinlonmon, The Vision of Escaflowne as Boris, and Gulliver Boy as Baron Fullmoon. His work extended to Western animation as well, with voice roles in series like The Real Ghostbusters and Ren & Stimpy.

His work in dubbing Hollywood films was equally extensive. He is remembered for voicing Tony Gazzo, played by Joe Spinell, in the redubs of the first two Rocky films. He also lent his voice to prominent characters in major films, such as Dr. Loomis in Halloween 5: The Revenge of Michael Myers, Superintendent Andrews in Alien 3, Father Dyer in the redub of The Exorcist III, and Professor Abraham Van Helsing in Dracula: Dead and Loving It. His career also included dubbing work for television series and Brazilian telenovelas like Women in Sand.

In addition to his extensive voice work, Roberto Sen was an accomplished on-screen actor. He appeared in numerous Mexican telenovelas over several decades, including Rubí, Amarte es mi pecado, Por amar sin ley, Papá a Toda Madre, and Antes muerta que Lichita. He was also active in theater, taking on leading roles and directing productions such as Cyrano de Bergerac and Don Juan Tenorio.

Parallel to his artistic endeavors, Roberto Sen maintained a long and distinguished academic career. He was a professor for over thirty years at the National Autonomous University of Mexico (UNAM), teaching Planning Systems in the Faculty of Engineering. This dual path as an artist and an educator highlights a life dedicated to both creative expression and academic rigor, leaving a legacy that extends beyond entertainment into the formation of new professionals.
