Daisuke Gōri (the stage name of Mr. Yoshio Nagahori) has passed away. From the Tokyo Shimbun and Anime News Network:
The Tokyo Shimbun paper reports that Daisuke Gouri, the voice actor best known for playing Robin Mask in the Kinnikuman television anime series as well as Umigame and Mr. Satan in the Dragon Ball franchise, has passed away in Tokyo on Sunday. He was 57.
The newspaper reports that Gouri was discovered, with blood dripping from his wrist, by a passerby on a street in Nakano ward. Police officers at Nakano station are investigating his death as a possible suicide. According to the authorities, Gouri apparently collapsed face-down onto the street at about 3:00 p.m. The Yomiuri Shimbun paper adds that a knife was found under him along with a last will nearby.
Gōri was easily one of the most prolific voice actors in our beloved series, playing characters such as Umigame, Gyū-Maō (Ox Demon King), Enma-Daiō, King Cold, Mr. Satan, and a constant flow of side characters throughout the entire airing.
His unbelievably deep voice ran the gamut of roles from stern to friendly back to cold-hearted and wacky, again. His talent was unmatched. If you watch anime at all, you know his voice. It is difficult to imagine anime, let alone just Dragon Ball, without Daisuke Gōri.
