The character was voiced originally by Paul Winchell, then by Rob Paulsen and currently by Jim Cummings. Winchell and Cummings have shared another role: Tigger from The Walt Disney Company's Winnie-the-Pooh stories. Winchell's facial structures were caricatured in the related character design as well. In various scenes, Dastardly would utter his catchphrases, "Drat, drat and double drat!" or "Triple drat!" and even "Curses, foiled again!" His other main catchphrase was, "Muttley, do something!"
