Characters You Didn't Realize Had The Same Voice Actor

Voice actors don't often get the same respect that live-action stars do. After all, how hard can it be to sit in a recording booth and do silly voices all day? You can even show up to work in your pajamas.

But really, the gig is incredibly hard. Voice actors may rarely get to be celebrities, but the best of them have a range that would make even Meryl Streep's head spin. If you don't know their names, you still know their work, and once you get digging into an actor's credits, you start to see them pop up in some unexpected places. 

Many animated shows can get a cast of thousands out of no more actors than you can fit in a booth together. And the best of these voice artists can play anyone — young or old, hero or villain, serious or cartoony — so well that it may shock you to learn that the same voice is coming out of two different mouths. From iconic animals to animated candy, these are the animated characters you didn't realize had the same voice actors.

If you talk about voice acting, and especially if you talk about versatility in the profession, you've got to talk about Mel Blanc. He was the first superstar in the field, thanks in no small part to a special deal he struck with Warner Brothers that made him the first voice actor to get his name — and his name alone — in the credits for all the classic "Looney Tunes" cartoons. However, he wasn't the only one voicing these beloved characters. For instance, Arthur Q. Bryant played Elmer Fudd, and moonlighting sound effects man Treg Brown played the Road Runner. 

Nevertheless, Blanc was the dominant voice of the series, as he played nearly everyone else and defined some of the most iconic personalities in animation history in the process, from the fast-talking, superhumanly smooth Bugs Bunny to stuttering everyman Porky Pig. However, Blanc is less famous for his contributions outside the Warners' lot, but there are plenty of them, and odds are you've heard some of it before. 

He put in a lot of work for the cartoon hit factory at Hanna-Barbera, including a modified Bugs voice for Secret Squirrel and the hollering of Captain Caveman. And he voiced another true icon as the original Barney Rubble on "The Flintstones." Hanna-Barbera modeled their modern Stone Age family on the then-popular sitcom "The Honeymooners" and contracted Blanc to do his own version of Art Carney's character, Ed Norton. But Blanc insisted he didn't do impressions, so he made Barney Rubble his own, with a voice that other stars continue to imitate in new "Flintstones" projects.

Mel Blanc may have played most of the male "Looney Tunes" characters, but acting across genders was too much even for him. That means the women, including Witch Hazel and Tweety Bird's Granny, were played by June Foray. And that's just the beginning of a long career that continued with appearances in "How the Grinch Stole Christmas," "DuckTales," and 1998's "Mulan."

But if you want to see just how versatile Foray was, you don't need to look across all of her projects. In "The Adventures of Rocky and Bullwinkle," she proved she could do two incredibly different voices at once, playing both a high-voiced little boy (or squirrel) and a husky-voiced older woman. This classic cartoon chronicled the adventures of Foray's Rocky the Flying Squirrel and his friend, Bullwinkle the Moose (Bill Scott). 

They crossed the globe fighting two spies from the faux-Soviet nation of Pottsylvania, Boris Badenov (Paul Frees) and Natasha Fatale, who was also played by Foray. But tell any kid watching the show that the same woman read both sides of any conversation between Rocky and Natasha, and they'd probably look at you like you'd grown another head.

They'd already found huge success with the early Mickey Mouse and "Silly Symphonies" shorts, but Disney became a bona fide major player in Hollywood with the blockbuster success of "The Three Little Pigs." No small part of the credit for that should go to Billy Bletcher, whose booming, menacing voice as the Big Bad Wolf made sure that, whatever the song said, every kid in the audience was afraid of him. 

Bletcher brought that same distinctive voice to Mickey Mouse's enemies, Peg-Leg Pete and the Mad Doctor, as well as Pa Bear in "Bugs Bunny and the Three Bears" and literally hundreds of others characters.

When we think of voice work, we generally think of animation, but live-action calls for voice actors pretty frequently, too. One of the greatest classics of the 1930s, "The Wizard of Oz" drew on Bletcher's talents, along with fellow Disney voice actor Pinto Colvig (the voice of Grumpy in "Snow White" and Goofy) to dub over some of the vocals in the show-stopping performance of "Ding Dong, the Witch Is Dead." You'd be forgiven for not recognizing Bletcher here, since his deep baritone has been sped up until it sounds like something closer to a soprano.

All these roles show a lot of range, but could any one actor play both the heroic leader of an army of superpowered robots and a mopey cartoon donkey? Well, Peter Cullen could, and he did. He's voiced nearly every incarnation of "Transformers" leader Optimus Prime since the original TV series in 1984. Even in the live-action movies, where Optimus' nemesis, Megatron, got the star treatment from Hugo Weaving of "The Matrix" fame, no one but Cullen could play the role.

Around the same time he took the reins of the Autobots, Cullen assumed the role of Winnie the Pooh's friend Eeyore from Disney animator Ralph Wright for the "New Adventures of Winnie the Pooh" TV series. While other actors have occasionally stepped in, including Pixar/"Sesame Street" animator Bud Luckey in the 2011 "Winnie the Pooh" movie and "Everybody Loves Raymond" star Brad Garrett in the live-action "Christopher Robin," Cullen still keeps his Eeyore voice in tune, playing the stuffed donkey as recently as a 2017 crossover with "Doc McStuffins."

The classic "Babe" movies star an adorable little pig who's so full of innate goodness that, just by his presence, he transforms the harsh environments of the farm he grew up on and the city where he's stranded in the sequel, "Babe: Pig in the City." In other words, those films are as far as you can get from "Dexter's Laboratory," a series about an egotistical, maladjusted little boy genius with an inexplicable Germanic accent who causes mayhem and destruction with his strange inventions. 

But both characters come from the same source. Like most children in the world of voice acting, they're played by an adult woman, the late Christine Cavanaugh. But who knows, maybe a meeting with Babe would have convinced Dexter to mend his ways. Some of Cavanaugh's other credits include Darkwing Duck's niece, Gosalyn Waddlemeyer, Marty Sherman in "The Critic," Oblina of "Aaahh!!! Real Monsters!", Bunnie Rabbot in "Sonic the Hedgehog," and Chuckie on "Rugrats," along with occasional on-camera appearances in projects like "Jerry Maguire" and an episode of "The X-Files."

The voice cast is an undervalued part of the success of "The Simpsons," and few actors have carried more weight than Nancy Cartwright. Bart could have easily just been a one-note brat, but Cartwright gave him a fragile, believable soul. 

While she's not as prolific as some of her castmates, Cartwright is still responsible for a good portion of the Springfield population, including clueless Ralph Wiggum, Rod and Todd Flanders, and school bullies Nelson Muntz and Kearney. She's carved out a niche playing kids in other shows, as well, including "Goof Troop," "Animaniacs," and "Rugrats," where she took over the role of Chuckie after Christine Cavanaugh's death in 2014.

One of Cartwright's roles, though, is a lot further removed from what you'd expect based on "The Simpsons." In fact, it can be hard to think of it as voice acting since it doesn't involve any intelligible words at all. In "Kim Possible," Cartwright appears as Ron Stoppable's pet naked mole rat, Rufus. Even though he can't talk, Rufus still manages to make himself understood through all his little squeaks and grunts, and he may actually be a more useful sidekick for Kim than his accident-prone owner.

"The Simpsons" has built one of the biggest supporting casts in cartoon history, with apparently every citizen of Springfield appearing at one time or another alongside hundreds of famous characters, both real and fictional. And they've managed to do that with just a bare handful of voices: Almost all those characters are played by either Hank Azaria, Harry Shearer, or Dan Castellaneta. 

Along with playing the Simpsons' patriarch, Homer, Castellaneta has also starred as — just for starters — Barney Gumble, Krusty the Clown, Groundskeeper Willie, Sideshow Mel, Mayor Quimby, Hans Moleman, and Grampa Simpson. But what was even more impressive was that he played another old man without sounding at all like Grampa Simpson. That's exactly what Castellaneta did when he took on the role of Grandpa Phil on "Hey Arnold!", and you probably never would have guessed it if someone hadn't told you. 

Even more impressive than that, Castellaneta has been able to play those old men as young men while still keeping them recognizable in a series of flashback sequences, including one memorable moment where Grandpa Phil beats the hell out of Adolf Hitler. (Grampa Simpson, meanwhile, infiltrated the Fuhrer's inner circle by disguising as a cabaret dancer.)

"The Simpsons" was revolutionary when it debuted in 1989. Offering up a dose of sharp, cynical wit to a primarily adult audience, it proved that not all animation had to follow the Disney model. But that hasn't stopped "The Simpsons" cast from sharing some talent with their competitors at the Mouse House, including the voice of one of Disney's oldest characters.

Russi Taylor first took up the Minnie Mouse mantle for the Disney Channel movie "Doggone Valentine" in 1987, joining her real-life husband, Wayne Allwine, who'd been playing Mickey ever since he joined "The New Mickey Mouse Club" in 1977. Taylor inherited several other classic Disney roles over the course of her career, most prominently with a starring role as Huey, Dewey, and Louie in the original "DuckTales."

At the same time, she also joined the cast of "The Simpsons" as Martin Prince, the extravagantly nerdy teacher's pet at Springfield Elementary. She also played portly foreign exchange student Uter, as well as Bart and Lisa's twin tormentors, Sherri and Terri. On top of all that, she was also the Great Gonzo on "Muppet Babies." But her most important jobs were always Minnie and Martin, who she continued to play all the way up to her death in 2019.

Ron Perlman's distinctive jawline and 5'11" frame have typecast him playing monsters ("Beauty and the Beast"), tough guys ("Sons of Anarchy"), both ("Hellboy"), or a literal caveman ("Quest for Fire"). But in animation, he can be anyone he wants to be, and he's proven he's more than up to it. He returned to his "Hellboy" role in a series of animated movies, but he also terrified at least two consecutive generations of children as underhanded villains who rely more on subtle, whispered menace than imposing physicality, with Slade on "Teen Titans" and the Lich in "Adventure Time."

Both of these characters are deadly serious threats no matter how wacky their surroundings get, but Perlman has also shown he can get goofy himself in an almost unrecognizable role in "Danny Phantom." This turn-of-the-century Nickelodeon series followed a teenager who returns from a dimension of ghosts with superpowers and finds himself fighting other escapees from the same parallel world. Perlman, far from his usual bad guys and cool dudes, plays Danny's dorky vice principal, Mr. Lancer, trading his usual quips for nonsensical exclamations like "Gulliver's Travels!" A lot of teachers claim to swear by the classics, but we guess this one really does.

Tom Kenny rose to fame in live action on the cult "Mr. Show" sketch comedy series, but he found his true calling as a voice artist. It's certainly hard to imagine any actor who wouldn't kill for a role like SpongeBob SquarePants, one of the most recognizable characters in the world, and one that's probably netted Kenny millions, if not billions, in royalties.

SpongeBob is such a lovable, cheerful, good-hearted character that it's easy to see how he's become so popular. You couldn't say the same about the bitter, lonely, frequently psychotic Ice King who Kenny played on "Adventure Time." But that didn't stopped the actor from giving at least as brilliant a performance on that series, and he's even got to show off his dramatic chops with the Season 2 reveal of the Ice King's past life as an ordinary man named Simon Petrikov.

That's just the tip of the iceberg (heh) as far as Kenny's range, which also encompasses SponegBob's pet snail, Gary, the narrator and mayor in "The Powerpuff Girls," Rabbit in the "Winnie the Pooh" movie, the dog half of Catdog, and a frighteningly intense, self-loathing take on Dr. Octopus for "Ultimate Spider-Man."

"Futurama" creates a whole 31st-century world full of bizarre characters, but you might be surprised to find out how many of them came from one man's voice. Billy West stars as Philip J. Fry, a delivery boy who gets locked in a cryogenic tank on New Years' Eve, 1999. He also stars as Fry's distant descendant, Professor Hubert J. Farnsworth, the owner of Planet Express. And then there's the preserved head of Richard Nixon, the incompetent Dr. John Zoidberg, and Zapp Brannigan, the even more incompetent but far more self-assured general for the Democratic Order of Planets. 

Zapp was actually written for Phil Hartman, star of "Saturday Night Live" and "NewsRadio" and frequent guest star on "The Simpsons," before his untimely death forced West into the role. But West did a remarkable job recreating what Hartman's performance might have sounded like, and he's said that he drew inspiration for their mutual love of what he calls "big, dumb announcers." West also plays all kinds of minor characters, including an unexpectedly moving performance as God himself in "Godfellas."

"Futurama" is the best example of West's range, but it's just a small part of his long career, which includes playing Stimpy on "Ren and Stimpy" (you can actually hear bits of that voice creeping into Fry and Farnsworth in the early episodes of "Futurama"). He also starred in "Doug," played Elmer Fudd and Bugs Bunny in "Space Jam," and rapped verses written by a young Jay-Z for the soundtrack album.

Phil LaMarr stars in "Futurama" as Hermes Conrad, a Jamaican accountant who defies all the usual laid-back stereotypes with his uptight attitude. Hermes' seriousness can be very funny, but that's not so true for the stoic Samurai Jack, whose rare spoken words were also provided by LaMarr. 

This unflappable feudal warrior has been lost in the distant future in his quest to destroy Aku, the shape-shifting master of darkness, and return to his own time. The creators of "Futurama" had a little fun with LaMarr's warrior role in their "Reincarnation" episode, which featured three parodies of other genres, including an anime adventure where Hermes transforms into a samurai.

You may have also heard LaMarr as Wilt in "Foster's Home for Imaginary Friends," the Green Lantern in "Justice League," Dracula in "The Grim Adventures of Billy and Mandy," and the title role in "Static Shock." You won't see his face on camera often, but the moment where John Travolta accidentally blows it to bits in "Pulp Fiction" is one of the most memorable in LaMarr's long and varied career.

J.K. Simmons won an Oscar for his downright terrifying performance as a pathologically demanding music teacher in "Whiplash". But most of us probably know him best as J. Jonah Jameson, Peter Parker's blowhard boss in the "Spider-Man" movies, a role he's returned to in animated "Spider-Man," "Hulk," and "Avengers" series, as well as "Robot Chicken" and "The Simpsons." 

Simmons has taken plenty of other voice roles as well, and most of them fit into the same persona — the bovine warlord Kai in "Kung Fu Panda 3," a very un-jolly St. Nick in "Klaus," Omni-Man in "Invincible," Mayor Lionheart in "Zootopia," Tenzin in "The Legend of Korra," and many others. But there's one odd man out in his credits, so much so that even when you know it's him, it's still kind of hard to believe it. 

As a young actor in 1996, Simmons got a job playing the goofy yellow M&M opposite Billy West as the red one in the brand's commercials. Apparently, he hasn't let fame make him forget where he came from because he's still appearing in those commercials to this day. Just for fun sometime, try imagining the yellow M&M reading lines from Simmons' other characters and vice versa.

Tara Strong is one of the industry's most prolific voice actors, lending her vocal talents to a variety of characters and projects, including "My Little Pony," "Powerpuff Girls," and "Rugrats." Strong is credited with over 1,300 characters across nearly 500 different titles, making her one of the most active voice-over artists of the 21st century.

There's little doubt you've heard Strong somewhere, even if you didn't identify her voice. This is because she can modulate her tone in ways that make her sound completely different from one character to another. One of her most famous characters is Harley Quinn, who first appeared not in the comics but in "Batman: The Animated Series."

While that makes her the OG Harley, Strong also crossed over to Marvel by providing the voice for Miss Minutes in both seasons of "Loki." Neither character is similar, nor do they sound alike, which is a testament to Strong's inimitable talent. Miss Minutes and Harley Quinn both eventually found their way into the comics, but it's likely neither would be as big a success as they are were it not for Strong.

Some voice actors start out in front of the camera, but Tress MacNeille wanted to be behind the microphone since she was eight. It took her some time to build up enough credits, but eventually, she began playing recognizable characters in a variety of series and feature films. 

She's probably best known for voicing Daisy Duck, which she began doing in 1999. Since then, MacNeille has been the go-to voice actor for the character, playing her in 60 different TV shows, movies, shorts, and video games. Voicing a Disney animated character has kept MacNeille busy for almost three decades, but Daisy is hardly her only voice acting credit: MacNeille has amassed over 1,000 character voices across more than 350 titles.

If you want to hear a character who sounds nothing like Daisy, look no further than Mom in "Futurama." MacNeille also started voicing Mom in 1999 and has played her in the four "Futurama" movies, the video game, and numerous episodes of the TV series. Mom is cantankerous, abusive, and maniacal, making her entirely antithetical not just to Daisy, but every character MacNeille has voiced on shows like "Veggie Tales" and dozens of other animated projects.

Patrick Warburton is primarily an on-camera actor who's appeared in everything from "Seinfeld" and "Agents of SHIELD" to "Get Smart" and "The Tick." He's also lent his voice to numerous animated characters over the years, notably voicing Brock Samson in "Venture Brothers." He gained a lot of attention playing Joe Swanson in "Family Guy" and Kronk in "The Emperor's New Groove," but they make up only a handful of his credits.

Warburton has voiced 80 different characters across nearly 65 titles, and some of his more impressive roles include Rip Riley in "Archer" and Buzz Lightyear in "Buzz Lightyear of Star Command." He also played Buzz in the video game adaptation of the television series, taking over in both for Tim Allen, who voices the space-based action figure in the "Toy Story" film franchise.

Despite having a distinctive, deep baritone voice that's easy to recognize and identify, Warburton modifies his intonation for each character and injects a unique personality into them. While he's known for his deep tones, he can raise it to surprisingly high levels.

Chris Rock is probably best known for his standup comedy and on-camera acting in everything from "Dogma" and "Saturday Night Live" to "New Jack City" and "Beverly Hills Cop II." He's also done some voice acting, but he hasn't diversified his vocal talents much since stepping behind the microphone and has less than 20 credits in even fewer titles.

To many fans, he's Marty from the "Madagascar" franchise, which he's voiced in seven movies, commercials, and a television series. Outside of that role, Rock has two other notable characters he's lent his talents to: the title role in "Osmosis Jones" and Kitty in "Paw Patrol: The Mighty Movie." These are vastly different characters, and while Rock does a fantastic job breathing life into them, they sound similar.

His characters may not sound different, but Osmosis Jones is about as far removed from a talking kitty as you can get. He's a white blood cell police officer who fights to cure his host (Bill Murray) from an evil virus that invades his system. The movie bombed, which may be why Rock didn't return to voice the character in the TV show, leaving the role open for Phil LaMarr.

Dionne Quan doesn't have a ton of voice-acting credits, but she's been doing it since she was a teenager. When she was 10, Quan began taking drama lessons after school, and four years later, she landed her first gig, doing voice-over work in a health maintenance organization's commercial. 

Quan is visually impaired but hasn't let that slow her down. She's managed to land some significant jobs over the years, having learned to read braille at age seven. Quan made her feature film debut by providing the voice for Kimi Watanabe in "Rugrats in Paris: The Movie." Once she had the role, she continued to voice Kimi in several series and video games, including "All Grown Up!"

While Quan is well known for playing Kimi, another character who sounds different enough that some fans might not identify her is Trixie Tang from "The Fairly OddParents." Another character Quan has had the opportunity to voice is Toph in "The Last Airbender" franchise. She's also worked on several movies, including voicing Yasmin in four "Bratz" films, and she's done the same for a variety of video games.

A talented singer and on-camera actress, Elizabeth "E.G." Daily is also known to her fans for voicing many memorable characters. She's the type of voice actor who jumps from animation to live-action and back again repeatedly. She took over the role of Babe in "Babe: Pig in the City" and also voiced Bamm-Bamm Rubble in 1994's live-action "The Flintstones."

Daily has had over 280 roles across 120 titles, most notably voicing Tommy Pickles in "Rugrats" and "All Grown Up!" since the series premiered in 1991. In addition to playing the lead role of Tommy, Daily has voiced 48 other characters in that series alone.

While Tommy first brought Daily's talents to kids everywhere, she's also voiced another popular character in children's animation: Buttercup from "The Powerpuff Girls." Daily has voiced Buttercup in over 20 productions, including commercials, and recently reprised the role in 2022's "MultiVersus" video game. Additionally, Daily has found voice work in more mature animation projects, including "The Avengers: Earth's Mightiest Heroes."

Seth McFarlane has never been shy about using his voice to breathe life into his characters, playing many of the leads himself on "Family Guy." Brian the Dog sounds almost exactly like McFarlane's speaking voice, but other characters are modulated enough to differentiate them despite the similar underlying tone. While McFarlane largely creates his own shows and characters, he's not unwilling to work on other projects, some of which have been surprising.

McFarlane parodied "Star Wars" in "Family Guy" after getting George Lucas' permission, but he's also popped up as Emperor Palpatine in "Robot Chicken." He doesn't sound like Ian McDiarmid, who plays the character in live-action, and is instead a bit closer to McFarlane's Stewie from "Family Guy." 

McFarlane has also played another dog — but not one that's similar to Brian — providing the voice for Seymour, Fry's dog in "Futurama." If you've seen the episode "Jurassic Bark," you know how sad it is, and while Seymour can't speak, he does belt out a Scooby-Doo-inspired rendition of Katrina and the Waves' "Walking on Sunshine," though McFarlane wasn't involved. Instead, McFarlane parodies Brian in another episode, asking, "Philip, have you lost weight?" as Seymour.

Jim Cummings is a leading player in the voice-acting game, providing his vocal talents to 1,250 roles across nearly 500 titles. He's been at it since 1985, when he voiced Lionel in "Dumbo's Circus." Working for Disney on that one project certainly paid off because he's been with the House of Mouse ever since. His most well-known role is Winnie the Pooh, which he started voicing in 1988's "The New Adventures of Winnie the Pooh."

Throughout his career, Cummings has played Pooh more than 100 times, and he's also voiced several popular characters in "Adventures of the Gummi Bears," "The Transformers," "DuckTales," and "Teenage Mutant Ninja Turtles." He's even done live-action voice-over work on movies like "Who Framed Roger Rabbit," "Space Jam: A New Legacy," and "Small Soldiers."

Another popular character in Cummings' filmography is none other than Darkwing Duck. He began voicing that character in 1991's eponymous series and continued in various video games and other projects. If you want to see just how talented Cummings is, compare his Pooh and Shredder from "Teenage Mutant Ninja Turtles," and you can see that his ability to alter his voice is incomparable.

While she's probably best known for her comedic work in movies and on "Saturday Night Live," Maya Rudolph has a burgeoning career as a voice-over artist. She first played an animated character on an episode of "The Simpsons," and if you've seen "Shrek the Third," you've heard Rudolph's talented voice as Rapunzel.

Fans of "Big Mouth" certainly know Rudolph, as she plays Connie the Hormone Monstress, who was introduced in the second episode. Of all her characters, Connie sounds the closest to Rudolph's speaking voice, though with some modifications. Rudolph has earned critical acclaim for playing Connie and took home the Primetime Emmy Award for outstanding character voice-over performance in 2020, 2021, 2023, and 2024.

While Rudolph has played another 14 characters on "Big Mouth," you might also recognize her as the voice of Aunt Cass from the "Big Hero 6" franchise. She first played the character in the feature film and continued in "Big Hero 6: The Series" and "Baymax!" Some of her other notable characters include Daniela Paguro in "Luca," ZOE3 in "Vader Immortal: A Star Wars VR Series," and Smiler from "The Emoji Movie."

Mindy Kaling wears many hats as an entertainer, having excelled on television, in the theater (where she earned a Tony Award), as a comedian, and in movies. Most people first met Kaling when she played Kelly Kapoor in "The Office," and she's built up an impressive career that also includes voice-over roles, though she's relatively new to that field. As of 2025, Kaling only has eight roles in eight titles, but that number is likely to grow.

Kaling earned a lot of attention voicing the title character in "Velma," though the series didn't do well with viewers. That wasn't a result of Kaling's vocal talents; the series was derided for how it updated the characters, along with other issues. Regardless, Kaling did an impressive job playing a character who's been around since the 1960s and has a sizable cult following.

"Velma" didn't work out as planned, but Kaling had a great deal of success voicing Disgust in the two "Inside Out" films. She also played Taffyta Muttonfudge in "Wreck-It Ralph," though she didn't reprise the role in the sequel, as well as Val Little in "Monsters at Work." Her best-known voice roles for now are Velma and Disgust.

As an actor and sketch comedy player for decades, Nicole Sullivan is probably best known for her work on "MADtv" and "The King of Queens," while also appearing in everything from "Cougar Town" to "Pee-wee's Big Holiday." She began voice acting in the 1990s and was originally cast to play Leela in "Futurama," but the role went to Katey Segal before production began.

Fortunately, that didn't end her voice-acting career, and she's since played over 60 roles in more than 40 titles. One that's often overlooked is Muriel Goldman from "Family Guy," one of the rare animated characters to earn a permadeath after being killed off in the aptly-titled Season 9 episode, "And Then There Were Fewer." Unlike most characters, she's never been brought back, which is unusual for animated projects.

What isn't unusual is Sullivan's talent as a voice actor because she's also the voice of none other than Supergirl. She started voicing Superman's Kryptonian cousin in 2012's "Super Best Friends Forever" and has reprised the role in six different productions. Most recently, Sullivan played Supergirl in 2022's "Teen Titans Go! and DC Super Hero Girls: Mayhem in the Multiverse."

A renowned voice actor, John DiMaggio got started in the entertainment industry as a stand-up comic. He also snagged some on-camera roles in shows like "Law and Order," "Modern Family," and "Chicago Hope." Still, while he's happy to act in front of a camera on a set, he's at home behind a microphone, where he creates unique voices for characters in movies, television series, and video games.

DiMaggio started working as a voice-over artist in the 1990s, beginning with commercials and other minor roles. In 1999, he got his big break when he was cast to play Bender Bending Rodríguez in "Futurama." While the series has been canceled three times and brought back, he's remained attached as Bender. He's also voiced characters in "Futurama" creator Matt Groening's other series, "Disenchantment."

While those are memorable, another popular character DiMaggio has voiced is Jake the Dog from "Adventure Time." He's played Jake in several projects since the series first aired, and he's just one of many DiMaggio has voiced. Throughout his career, DiMaggio has amassed nearly 1,200 roles across 305 titles and remains an in-demand voice actor in Hollywood.

While he's best known for playing Luke Skywalker in the "Star Wars" franchise, Mark Hamill is no one-trick pony. Although he's acted on camera since 1970 and is the hero of one of the most popular film series of all time, it's hard to overlook his impact on voice acting. Long before he was cast to defeat the Empire in a galaxy far, far away, Hamill decided he wanted to do voiceover work when he was only five years old.

Before he fired up his father's lightsaber as Luke, Hamill was already a veteran voice actor, having provided several characters' voices in "The New Scooby-Doo Movies" and "Wizards." It would be another 15 years until Hamill landed a role that would define much of his career, playing The Joker in "Batman: The Animated Series."

He'd go on to portray the character in nearly every animated series, film, and video game for years, retiring the voice after the death of Kevin Conroy, who played Batman opposite him. He did play Joker once more but has seemingly retired from the role. Another legacy character in Hamill's filmography is Skeletor in 2021's "Masters of the Universe: Revelation," who sounds eerily similar to Joker.

Clancy Brown is one of those actors you've doubtless seen in something, though you may not recall his name. That's because he has a talent for dissolving into his roles: He was the Kurgan in "Highlander" and the Harbinger in "John Wick: Chapter 4," though he's probably best recognized for playing Captain Byron Hadley in "The Shawshank Redemption."

While he's had a long and successful career as an actor, Brown has been voice acting since the 1990s. Some early work on "Gargoyles" and "The Real Adventures of Jonny Quest" helped establish Brown in the industry, and in 1996, he began voicing Lex Luthor in DC's animated TV series and films. In 1999, Brown took on one of his most notable roles, playing Mr. Krabs in "SpongeBob SquarePants."

That's not a role "Highlander" fans would associate with the Kurgan, but Mr. Krabs is 100% Brown. Another interesting character he played that many might not have recognized is Surtur from "Thor: Ragnarok," indicating that Brown isn't opposed to voicing live-action characters. Additionally, "Star Wars" fans should recognize Brown's voice as Savage Opress in "Star Wars: The Clone Wars," making Brown part of two of Disney's biggest brands.

There aren't many voice actors with as many credits as Frank Welker, who boasts more than 2,100 across over 670 titles. Welker has been working as a professional voice actor since the 1960s, beginning with popular series like "Scooby-Doo, Where Are You!" Although Welker initially voiced Fred Jones, and not Scooby-Doo, he began portraying the latter in 2002 and has voiced Scooby ever since.

Because he's played so many memorable characters, from Superman villain Mr. Mxyzptlk and X-Men member Iceman to Inspector Gadget and Cujo, it's hard to pick his greatest. Still, there are some characters who outshine the rest, and those are indeed Scooby-Doo and Megatron from "The Transformers." He began voicing Megatron in "The Transformers" in 1984 and hasn't stopped, continuing to play the character in live-action and video games.

He also voiced 24 other characters in that series alone, including Soundwave.
