A comprehensive profile for a voice actor named "Bob Timoney" does not have readily available information in English-language sources. However, the anime role mentioned, Mr. Sakano from Gravitation, is consistently credited to the American voice actor Bill Timoney, who also uses the pseudonym Billy Regan. It is possible that "Bob Timoney" is a misspelling or a confusion with this established actor.

Bill Timoney is an American actor, voice actor, director, and scriptwriter with an extensive career in English dubs of anime. He was born William Regan Timoney on March 5, 1958, in Teaneck, New Jersey. Over his career, he has been credited under several pseudonyms, including Billy Regan, Danny Bush, and Randy Woodcock.

He is perhaps best known for his long-running work on the Pokémon anime series, where he has voiced numerous characters such as Harley, Conway, and Nando starting from the Advanced Generation series. Another prominent role is voicing the protagonist Parn in the English adaptation of Record of Lodoss War and its sequel, Chronicles of the Heroic Knight. He also provided the voice for Harunobu Madarame in Genshiken.

His involvement with Gravitation is well-documented. Under the name Billy Regan, he voiced the character Mr. Sakano, the stressed but well-meaning manager for the band Bad Luck, in the English-language dub produced by The Right Stuf International. In addition to this primary role, Timoney, credited under his own name, also provided voices for a bartender in one episode and other additional voices for the series.

Beyond acting, Bill Timoney has also contributed as a script writer and producer on various projects. In Gravitation specifically, he is also listed as a writer. His other notable anime voice credits include roles in Digimon Adventure, Fist of the North Star, Trigun, and Perfect Blue.
