William Richard Werstine    (born April 16, 1952),  known as Billy West, is an American voice actor, singer, comedian, musician, songwriter and former radio personality who is known for his voice-over work in a number of television series, films, video games and commercials. He has done hundreds of voice-overs in his career such as Ren (season 3 to season 5) and Stimpy on The Ren & Stimpy Show ; Doug Funnie and Roger Klotz on Doug ; and Philip J. Fry, Professor Farnsworth, Dr. Zoidberg, Zapp Brannigan and a number of others on Futurama . He does voices for commercials and is the current voice of the red M&M and was also the voice of Buzz, the Honey Nut Cheerios Bee until 2004. In addition to his original voices, he has voiced Bugs Bunny, Elmer Fudd, Shaggy Rogers, Popeye and Woody Woodpecker during later renditions of the respective characters. He was a cast member on The Howard Stern Show , noted for his impersonation of The Three Stooges'Larry Fine.
West worked at WBCN in Boston, performing daily on the air on The Big Mattress show, then moved to New York City in 1988, working at K-Rock Radio (92.3 FM WXRK). West became a regular on The Howard Stern Show at that time until leaving in 1995. West moved to Los Angeles, where he found success as a voice actor and performer.
West launched his career in the early 1980s, performing daily comedic routines on Boston's WBCN. He left the radio station in 1988 to work on the short-lived revival of Beany and Cecil , which was his first role in television. He was a cast member and impressionist on The Howard Stern Show during the 1990s, where he gained notice for his impersonations of Three Stooges middleman Larry Fine, Cincinnati Reds owner Marge Schott, and Stern's head writer Jackie Martling. West's most notable film work was in Space Jam (1996), providing the voice of both Bugs Bunny and Elmer Fudd. He has provided the same voices for other Looney Tunes films and video games.
West's first two high-profile roles, on Doug and The Ren & Stimpy Show, came almost simultaneously and were on two of the first original three Nicktoons (the other being Rugrats ). Over his career, West has been the voice talent for close to 120 different characters including some of the most iconic animated figures in television history. He has become one of few voice actors who can impersonate Mel Blanc in his prime, including characterizations of Bugs Bunny and Daffy Duck, the voice Arthur Q. Bryan used for Elmer Fudd, as well as other characters from Warner Bros. cartoons. In 1998, Entertainment Weekly described West as "the new Mel Blanc" and noted his ability to mimic well-known voices,  though he would rather develop original voices.  West's favorite characters are Philip J. Fry and Stimpy, both of which he originated.  West has been very outspoken over his displeasure about the influx of movie star actors providing voice-over for films and major shows.   West has stated that he did not like the Disney version of Doug and that he "couldn't watch" the show.   West was the voice of the show's namesake, Geeker, throughout Project Geeker ' s 13-episode run. West was the voice of Zim in the original pilot for Nickelodeon's Invader Zim . Richard Horvitz was chosen for the series role because West's voice was too recognizable, according to Invader Zim creator Jhonen Vasquez during DVD commentary. West is the voice of "Red" in numerous M&M commercials as well as the 3-D movie "I Lost my M in Vegas", currently playing at M&M's World in Las Vegas, NV. West also voices a number of characters in the series Rick & Steve: The Happiest Gay Couple in All the World . He does not play a regular character in that series but appears in almost every episode of the show voicing various minor and one-off characters. West voiced the character Moobeard in Moobeard the Cow Pirate, a short animation featured on Random! Cartoons , and reprises his role as Elmer Fudd in Cartoon Network's series The Looney Tunes Show . West provides the voice for the elephant/van Ellyvan in the Playhouse Disney show "Jungle Junction".
West provided the voice of Stimpy in Nickelodeon's The Ren & Stimpy Show from 1991 until 1996, and he later provided the voice of Ren Höek from 1993 to 1996 when Ren's original voice and series creator John Kricfalusi was fired by Nickelodeon for delivering un-airable episodes. West performed other characters on the series as well, such as Mr. Horse (another role that West was issued after Kricfalusi's departure) and the "Announcer/Salesman" of such shorts as the "Log" ads (a voice West would use years later as the Narrator for The Weird Al Show ).
According to West, he was originally supposed to do the voice of both Ren and Stimpy (and performed both characters on the tape that was used to sell the show to Nickelodeon), but then Kricfalusi decided to do the voice of Ren himself once the show was sold and he had West on board as part of the selling point.
West's roles in Futurama include Philip J. Fry, Professor Farnsworth, Zapp Brannigan, Dr. Zoidberg and various other incidental characters. As he and other Futurama cast and crew point out in DVD commentaries, West voiced so many characters throughout the series that conversations are often held entirely between characters he is voicing.
West went into the Futurama auditions and was asked to try out for, as he says, "just about every part"; [[CITE|-1|http://tvsquad.com/2006/06/15/billy-west-the-tv-squad-interview]] eventually landing the Professor, Zoidberg, and Zapp Brannigan.
The role of Zapp Brannigan was created for Phil Hartman, but he died before the show started and West was given the role. West has described his interpretation of Zapp Brannigan's voice as an imitation of Hartman, but described the actual vocalizations of the character as being based on "a couple of big dumb announcers I knew."
Futurama was renewed by Comedy Central as four direct-to-DVD films broken into 16 television episodes.  West reprised his roles for these films and was signed on for two new 26-episode production seasons (four 13-episode air seasons) of Futurama which aired summers of 2010–2013.
West was the announcer of the program Screen Gems Network which ran from 1999–2001. He was the promotional announcer for The Comedy Channel before it merged with HA! to become Comedy Central. Over his career, Billy West has voiced multiple characters in television commercials. These include (but are not limited to):
- Red, the plain/ milk chocolate M&M (1996–present) (after Jon Lovitz's departure from the role in 1996) 
- Buzz, the honey nut bee for Honey Nut Cheerios (1990–2004)
- An alien for Pentium 4
- Popeye for Minute Maid
- Babe Ruth, Mickey Goldmill,  and Bruce Lee for Brisk Iced Tea
- Marfalump, a mascot for Pepsi from 1999 to 2000; created to tie in with the release of Star Wars: Episode I – The Phantom Menace
West voiced the Speed Racer character in a late 1990s advertisement for Volkswagen,  because the commercial's producers could not locate Peter Fernandez, the original voice of Speed. However, the producers did locate Corinne Orr, the original voice for the characters Trixie and Spritle.
West appeared on Ken Reid's TV Guidance Counselor Podcast on January 30, 2015. The episode was recorded live at The Smell in Downtown Los Angeles during the third annual Riot LA Comedy Festival.
West began his own podcast show in July 2015.
Perhaps West's most notable film work came in the 1996 film Space Jam , where he provided the voice of both Bugs Bunny and Elmer Fudd. West reprised the roles of Bugs and Fudd in subsequent Looney Tunes feature-length films and returned as Fudd in the theatrically released Looney Tunes: Back in Action . In 1998, West starred in the direct-to-video film Scooby-Doo on Zombie Island as Shaggy Rogers, becoming the second person to portray the character (the first being Casey Kasem). He was one of the top contenders to replace Kasem after his retirement in 2009 but lost the role to Matthew Lillard. In 2000, he provided additional voices in Disney's Dinosaur . In 2004, West voiced the classic character Popeye in the 75th-anniversary film Popeye's Voyage: The Quest for Pappy , and made his live-action film debut in Mark Hamill's Comic Book: The Movie . He also appeared in a cameo in Garfield: The Movie . Other films featuring West's vocal talents include Joe's Apartment , Cats & Dogs , Olive, the Other Reindeer , TMNT , The Proud Family Movie , and three Tom and Jerry direct-to-video movies.
West is a guitarist and singer-songwriter with a band called Billy West and The Grief Counselors.
In 1982, West sang lead, doing an impersonation of Mike Love, on a Beach Boys-inspired tune, "Another Cape Cod Summer This Year," by studio band ROUTE 28, written and produced by Erik Lindgren on his Arf! Arf! Records label.
West has collaborated with Deborah Harry, Lou Reed, and Los Lobos, and he has played live on several occasions with Brian Wilson, including the guitar solo on the Beach Boys tune "Do it Again" on Late Show with David Letterman , in the mid-1990s. 
The Futurama episode "Proposition Infinity" features the track "Shut up and Love Me" which was written and played by Billy West and Greg Leon, under the name Wailing Fungus.

West was an occasional contributor to The Adam Carolla Show , a syndicated morning radio show that replaced Stern's show on CBS in LA. On February 19 and 20, 2007, The Howard Stern Show ran a special two-part retrospective of West's work with the show. It marked his first work with the show since leaving after his last show on November 1, 1995.
