Mae Questel: Popeye
Yes, the adorable Mae Questel played Betty Boop and Olive Oyl, but she also provided the voice of Popeye the Sailor Man at least six times, substituting for Jack Mercer, who regularly played Popeye from 1935 to 1961.
Regina King: Riley & Huey Freeman (The Boondocks)
We love Regina King's voice anyway, so it was only a matter of time before she gave life to animated characters. But with youthful curiosity, outrage, and toughness, she captured the voices of brothers Riley and Huey Freeman perfectly on The Boondocks.
June Foray: Rocky (Rocky and Bullwinkle)
June Foray's career in voice acting goes as far back as the 1940s, and she's played a grandmother in various roles for decades, but her best-known character is Rocket J. Squirrel, or Rocky.
Pamela Adlon: Bobby Hill (King of the Hill)
Louie fans may recognize Pamela Adlon as the woman who broke the star's heart, but Pamela Adlon has enjoyed a prolific career as a voice actor. She's played a few male characters, like Milo Oblong of The Oblongs, and every 20-something tomboy's childhood hero, Spinelli on Recess, but she also played Bobby, a seemingly typical teenage boy living in rural Texas.
Christine Cavanaugh: Dexter (Dexter’s Lab)
Male or female, who didn't want to be Dexter (or perhaps his obnoxious sister DeeDee)? He was a boy genius with a sick laboratory in the unsuspecting suburbs. If you're young enough to have watched Dexter's Lab without irony, you also probably recognize Cavanaugh's talents as the voice of Chuckie Finster on Rugrats.
Charles Adler: Bev Bighead (Rocko’s Modern Life)
Charles Adler has played tons of characters through the years, but he provided the voice for Rocko's grotesque, overbearing neighbors, Ed and Bev Bighead.
Tress MacNeille: Chip (Disney’s Chip and Dale)
Voice actor Tress MacNeille definitely has a voice you would recognize (as long as you're watch anything Matt Groening is in charge of). In addition to a ton of voices on The Simpsons and Futurama, MacNeille has also played several Disney characters, including Chip in multiple titles.
E.G. Daily: Tommy Pickles (Rugrats)
After several TV and movie acting gigs (Pee-wee's Big Adventure, Valley Girl) and a musical career in the 1980s, Elizabeth Daily played Tommy Pickles, the leader of the Rugrats (unless you count Angelica), for 15 years.
Nancy Cartwright: Bart Simpson (The Simpsons)
Nancy Cartwright is probably one of the most successful female voice actors working right now, and she's best known for the mischievous Bart on The Simpsons. But the Bartman is not the only guy she's played — there's been Billy in Betsy's Kindergarten Adventures, Todd Daring on The Replacements, and Chuckie Finster in the All Grown Up series spin-off of Rugrats.
Frank Welker: Uni (Dungeons and Dragons)
Dungeons and Dragons is the quintessential '80s fantasy animated show. Frank Welker, one of the most famous voice actors of all time, played Uni, the cutesy unicorn. His more typical roles, though, included Dr. Claw on Inspector Gadget and Megatron on Transformers.
Erika Scheimer: IMP and Loo-Kee (She-Ra)
Out voice actor Erika Scheimer has brought life to some of the '80s most iconic animated shows like Fat Albert and the Cosby Kids, and He-Man and the Masters of the Universe. But she swapped genders to play male characters IMP and Loo-Kee on She-Ra: Princess of Power.
