Call me crazy, but the voice acting in the early 2000s just hit different. You’ve got these shows that were supposed to be "just for kids," yet the booths were packed with legitimate heavyweights. Kim Possible is basically the poster child for this. It wasn’t just a cartoon; it was a masterclass in vocal chemistry. Honestly, when you look at the Kim Possible voice actors list today, it’s kinda staggering how much talent was squeezed into one 22-minute slot.
Most people remember Christy Carlson Romano and Will Friedle, but the bench was deep. Like, deep enough to include Emmy winners and the guy who voiced Bender from Futurama. It’s wild.
The Duo That Defined a Generation
Christy Carlson Romano wasn’t just a "Disney kid." While she was filming Even Stevens during the day, she was recording the voice of Kim at night. That’s a lot of work for a teenager. She brought this specific blend of "I can save the world" confidence and "I'm still worried about my crush" vulnerability that made Kim feel real. It wasn't just a high-pitched "hero" voice. It was grounded.
Then you have Will Friedle. If you grew up in the 90s, he was Eric Matthews from Boy Meets World. In the 2000s, he became the definitive Ron Stoppable. Friedle has this incredible ability to make Ron’s constant panic sound endearing rather than annoying.
The chemistry between Romano and Friedle wasn't an accident. They’ve actually remained close friends, even launching a podcast called I Hear Voices where they talk about the industry. You can tell they actually liked each other. That translates. When Kim and Ron are bickering about a "Naco" at Bueno Nacho, it sounds like two friends who have known each other since pre-K because, in a way, the actors had that same shorthand.
The Naked Mole Rat in the Room
We have to talk about Rufus. You might not realize it, but the squeaks and "huz-zah!" moments of everyone’s favorite pink rodent came from a legend. Nancy Cartwright. Yes, the voice of Bart Simpson was Ron’s pet.

Cartwright is a titan in the VO world. She didn't just make random animal noises; she gave Rufus a personality that was basically the heart of the team. Think about the range required to go from the rebellious kid of Springfield to a naked mole rat who knows kung fu. It’s impressive. She even came back for the 2019 live-action movie to voice Rufus again, which was a nice nod to the fans.
Why the Villains Stole the Show
Every hero is only as good as their villain, and Kim Possible voice actors Nicole Sullivan and John DiMaggio took that personally.
John DiMaggio voiced Dr. Drakken. If you know voice acting, you know DiMaggio. He’s the voice behind Bender (Futurama) and Jake the Dog (Adventure Time). For Drakken, he used this raspy, slightly over-the-top incompetence that made the villain lovable despite his constant attempts at global domination. He wasn't scary; he was a guy who just really wanted to be respected.
Then there’s Shego. Nicole Sullivan, a veteran of MADtv, voiced her. Shego was a revelation for Disney Channel. She was sarcastic, competent, and clearly more capable than her boss. Sullivan’s dry delivery—the constant sighs, the "whatever" attitude—made Shego a fan favorite.
- John DiMaggio brought the chaotic energy.
- Nicole Sullivan brought the grounded, "I'm too cool for this" energy.
- The resulting banter made the B-plots just as good as the action.
The Supporting Cast You Forgot
The show’s creator, Bob Schooley and Mark McCorkle, clearly had a great casting director. They pulled in people you wouldn’t expect.

Wade, the 10-year-old tech genius who stayed behind his computer, was voiced by Tahj Mowry. If that name sounds familiar, it's because he was the Smart Guy on The WB and Michelle Tanner’s best friend on Full House. Casting a real "smart kid" child star to play the cartoon's resident genius was a meta-move that worked perfectly.
Then you have the parents. Kim’s dad, Dr. James Timothy Possible, was voiced by Gary Cole (Office Space, Talladega Nights). Her mom, Dr. Ann Possible, was voiced by Jean Smart. Think about that for a second. Jean Smart—multiple Emmy winner, star of Hacks and Watchmen—was voicing a cartoon mom who also happened to be a brain surgeon.
And we can’t forget Patrick Warburton as Mr. Barkin. The man has the most recognizable voice in Hollywood. Whether he’s Joe Swanson in Family Guy or Kronk in The Emperor’s New Groove, Warburton brings a specific "gruff but well-meaning" vibe. As the substitute teacher who taught every single subject at Middleton High, he was the perfect foil for Ron Stoppable's laziness.
Minor Roles, Major Names
The show was a revolving door of guest stars.
- Raven-Symoné voiced Monique, Kim's best friend at the mall.
- Kirsten Storms (of General Hospital fame) played the ultimate mean girl, Bonnie Rockwaller.
- Patton Oswalt popped up as Professor Dementor.
- Ricardo Montalbán (yes, Khan himself) voiced Señor Senior, Sr.
- Debbie Reynolds voiced Kim’s grandmother, Nana Possible.
It’s actually kinda crazy when you list it out. The production value was top-tier. They weren't just hiring whoever was available; they were hiring icons to play bit parts.

The Legacy of the Voice Booth
The impact of these Kim Possible voice actors goes beyond just a four-season run. The show was one of the first Disney Channel cartoons to get a massive fan-led revival. When it was supposed to end after the movie So the Drama, the fans went wild. They wanted more. Disney listened, and Season 4 happened.
A huge part of that loyalty came from the voices. You can draw a character any way you want, but the soul comes from the performance. When Christy Carlson Romano says, "What's the sitch?" it’s iconic because of the way she says it. It’s a mix of boredom and readiness.
If you’re looking to get into voice acting yourself, or if you just want to relive the nostalgia, pay attention to the timing. The way DiMaggio and Sullivan bounce off each other in the Drakken/Shego scenes is a textbook example of comedic timing in animation. They weren't always in the booth at the same time, but they sound like they were. That’s the trick.
Next time you’re scrolling through Disney+ or catching a clip on YouTube, listen for the nuances. Notice how Tahj Mowry’s voice changed as he actually grew up during the series. Look for the guest stars you missed when you were eight. The show holds up because the people behind the microphones took it seriously.
To really appreciate the craft, go find an episode where Drakken and Shego are just arguing about their grocery list or their evil lair’s decor. That’s where the magic is. You’ll hear two professionals who know exactly how to make a ridiculous situation feel human.
For anyone who wants to dive deeper into the world of VO, checking out the I Hear Voices podcast is a solid move. Will and Christy talk to a ton of their former co-stars, and it gives you a look behind the curtain at what those recording sessions were actually like. It turns out, saving the world is a lot of work, even if you’re only doing it with your voice.
