Frank Welker

Frank Welker is an American voice actor, specializing in animal and other creature vocal effects. Welker has been involved in many 1980's and 1990's cult cartoons, including Megatron and Soundwave on The Transformers (which he would later reprise for the 2010 series, Transformers: Prime, both co-starring Peter Cullen) Doctor Claw from Inspector Gadget (also starring Don Adams, Cree Summer, and Maurice LaMarche), and Slimer on The Real Ghostbusters (also starring Arsenio Hall). He was also Abu from Aladdin, Fall Apart Rabbit on Bonkers (also starring Jim Cummings), and Nibbler in Futurama (starring Billy West, John DiMaggio, Lauren Tom, and Phil LaMarr). Since the 2000's, he has been the voice of Curious George (co-starring Jeff Bennett and Rino Romano) and Garfield the cat in The Garfield Show (also featuring Jason Marsden and Audrey Wasilewski).

Throughout the history of Scooby-Doo, Welker has provided the voice of Fred Jones in almost every animated incarnation his character appeared in (except for A Pup Named Scooby Doo, in which a younger version of Fred was played by Carl Steven), and has provided the voice of Scooby-Doo since 2002, succeeding Scott Innes. He is the only voice actor to remain throughout the Scooby-Doo franchise since its inception in 1969, the same year his voice acting career began.

Notes/trivia

 * He's also appeared on-screen, with none other than Elvis Presley in the film, The Trouble with Girls, which also starred Nicole Jaffe.
 * Fred's interest in Elvis in What's New, Scooby-Doo?, may be an allusion to that.
 * While Welker failed his audition for Scrappy-Doo, his adlib of "Puppy power!" proved successful according to Joseph Barbera, becoming his most popular catchphrase.
 * In DC Comics' Scooby-Doo! story Who's Who in Scooby-Doo, Welker is the namesake of an art museum worker who turns out to be the culprit.
 * In the What's New, Scooby-Doo? episode, he had a non-speaking cameo as the real identity behind a Hollywood extra pretending to be an evil Fred.
 * Due to the end credits alphabetising the actors by last name on Shaggy & Scooby-Doo Get a Clue!, Welker is listed last, despite playing one of the main characters. This is fixed for Scooby-Doo! Mystery Incorporated, but the same exception isn't applied to the Welker's main role(s) of Be Cool, Scooby-Doo!, where Welker's first role is Fred, then Scooby.
