Maxwell Atoms is a weird guy. I mean that as a total compliment. When he pitched a show about two kids who win the personification of Death in a limbo match, Cartoon Network was in its experimental "Big Pick" era. It was 2001. People were still processing the 90s, and suddenly we had a show where a skeleton with a Jamaican accent was forced to be best friends with a cynical blonde girl and a kid who regularly ate his own boogers. It was gross. It was cynical. It was perfect.
Finding shows like The Grim Adventures of Billy & Mandy today feels like a scavenger hunt in a graveyard. Most modern animation is either hyper-sincere and plot-heavy or strictly for preschoolers. That middle ground—the "ugly-cute," mean-spirited, chaotic energy of the early 2000s—is a dying breed.
If you're looking for that specific brand of supernatural slapstick, you have to look for creators who aren't afraid to let their characters be unlikable. Billy was an idiot. Mandy was a sociopath. Grim was a miserable servant. Yet, it worked.
The DNA of Creepy Comedy
What actually made Billy & Mandy tick? It wasn't just the monsters. It was the contrast. You had the vibrant, thick-lined art style of the era clashing with Lovecraftian horrors and existential dread. If you want something similar, you're looking for "Dark Whimsy."
Invader Zim
This is the most obvious sibling. Jhonen Vasquez came from the world of underground comics—Johnny the Homocidal Maniac, specifically—and brought that jagged, screaming energy to Nickelodeon. Like Billy & Mandy, Invader Zim thrives on the "stupid vs. mean" dynamic. Zim is the arrogant, incompetent alien; Dib is the obsessed, paranoid human. It’s loud. It’s filthy. It’s obsessed with internal organs. If you haven't seen the Enter the Florpus movie on Netflix, it captures that 2001 vibe with 2026 production values perfectly.

Courage the Cowardly Dog
John R. Dilworth’s masterpiece is less "funny-mean" and more "atmospheric-horror-comedy." While Billy and Mandy were often the aggressors in their world, Courage is the victim. But the overlap is in the character design. Both shows used "grotesque-up" shots—sudden, hyper-detailed, disgusting close-ups of faces or objects. It’s a specific visual language that tells the viewer: this world is not safe.
Why Modern Cartoons Feel Different
Most people don't realize how much the "CalArts style" changed things. I’m talking about the soft, rounded, bean-shaped characters of the 2010s. Shows like Steven Universe or Adventure Time are brilliant, but they have a soul. Billy & Mandy didn't really have a soul, and it was proud of it. It was a comedy of errors where nobody learned a lesson.
Honestly, the closest we’ve gotten lately is PsychicPebbles (Zach Hadel) and Michael Cusack’s Smiling Friends.
It’s an Adult Swim show, so it’s for a different demographic, but the spirit is identical. It’s short, punchy, and features character designs that look like they were pulled from a fever dream. One character might be a beautifully rendered 3D rotoscoped man while the protagonist is a yellow little guy with a huge nose. That visual anarchy is the true successor to the Atoms era.

The Supernatural Sitcom Trope
The core of the show was a "Supernatural Sitcom." You take a cosmic horror and make him do laundry.
- Chowder: Created by C.H. Greenblatt, who actually worked on Billy & Mandy. You can see the influence in the breaking of the fourth wall. The characters know they're in a cartoon. They talk to the audience. They run out of budget and have to wash cars in real life to pay for the animation.
- The Marvelous Misadventures of Flapjack: This is the bridge between the old-school gross-out humor and the new-age surrealism. It’s nautical horror. It’s disturbing. It also happened to be the training ground for the creators of Gravity Falls and Over the Garden Wall.
Speaking of Over the Garden Wall, it’s a bit too "artistic" to be a direct match, but the inclusion of the Beast and the eerie, folk-horror vibes definitely scratch that itch for people who liked the more "Grim" side of the adventures.
The "Mean" Comedy Vacuum
We don't do "mean" humor for kids much anymore. There's a lot of focus on empathy in modern writing. That’s great for society, probably, but it’s a bit of a bummer for those of us who grew up on Mandy ruthlessly exploiting everyone around her.
If you want that specific edge, you have to look at Dan Vs.. It’s an underrated gem about a guy who thinks the world is out to get him, so he declares war on things like "The Dentist" or "Canada." It has that same relentless, cynical pace. No one is "good" in Dan Vs., and that’s why it's funny.

Why We Still Care About These Shows
Why does a 20-year-old show about a skeleton still have a cult following?
Because it was fearless.
There’s a famous episode where Mandy smiles and it literally breaks reality, turning the world into a Powerpuff Girls parody before collapsing into nothingness. It wasn't afraid to be weird for the sake of being weird. Most shows like The Grim Adventures of Billy & Mandy share this trait of "Conceptual Nihilism." They suggest that the universe is big, scary, and ultimately hilarious.
Courage and Cowardice in Animation
In the early 2000s, creators like Danny Antonucci (Ed, Edd n Eddy) and Maxwell Atoms were allowed to be "creators" first and "brand managers" second. This resulted in shows that felt handcrafted and idiosyncratic. When you watch Billy & Mandy, you are watching one person's specific, twisted sense of humor.
Ranking the Vibe: What to Watch Next
- Smiling Friends (Adult Swim): If you want the modern version of surreal, gross-out humor. It’s fast. It’s bizarre. It’s the closest thing to the spirit of the early 2000s internet and TV crossover.
- Invader Zim (Nickelodeon/Netflix): For the gothic, screaming aesthetic. It’s the visual twin of the Grim World.
- Regular Show (Cartoon Network): It starts normal and ends with a god-tier battle in space. It captures the "escalation" that Billy & Mandy did so well.
- The Ren & Stimpy Show: The grandfather of the whole "ugly" movement. It’s much more intense and arguably more disturbing, but you can’t have Mandy without Ren Hoek.
Actionable Steps for the Nostalgic Viewer
If you're trying to recapture that specific feeling, don't just look for "cartoons." Look for the creators.
- Follow the Storyboard Artists: Look up the credits for your favorite Billy & Mandy episodes. Many of those artists moved on to projects like Adventure Time, Gravity Falls, or Rick and Morty. You'll find "spiritual" sequels in the background gags of these newer shows.
- Check Out "Indie Animation" on YouTube: This is where the Billy & Mandy energy moved. Since networks got "safer," creators went to the internet. Look for pilots like Helluva Boss or Ramshackle. They embrace the dark, the gritty, and the hilarious without the filter of a standards and practices department.
- Revisit the Shorts: Before it was a full show, it was part of Grim & Evil. Some of those original shorts have a much raw-er, more experimental feel than the later seasons.
The reality is that we might not see a "Big Three" network greenlight a show exactly like The Grim Adventures of Billy & Mandy again. The industry has shifted toward cinematic serialized storytelling. But the DNA is still there, buried in the dark corners of streaming services and independent studios. You just have to be willing to look into the underworld to find it.
