The Scooby-Doo franchise extends across movies, comics, and video games, but the original Scooby-Doo, Where Are You? animated series holds a special place in many fans' hearts. It's where all the shenanigans began, and the threats the Scooby Gang faced within were some of the most compelling.

Updated July 29, 2023, by Callum Murray: The beauty of Scooby Doo: Where are You? is the scope of villains that can feature in the show. There's cat creatures, ghosts, swamp monsters and many more that feature in each episode. But the thing that makes it most interesting is the human being that hides behind these monsters, revealing their very real motivations ranging from stealing an inheritance to revenge for a missed opportunity. The reveals are always fun and hokey and feature memorable villains in every episode. That's what makes the show the unique cult hit it still is today, years after it originally aired.

18 Ghost Of Captain Cutler

The Ghost Of Captain Cutler from A Clue for Scooby Doo

"A Clue for Scooby-Doo" introduces viewers to the Ghost of Captain Cutler, a villain who remains iconic in large part thanks to his glowing seaweed, footprints, and diving suit. Most villains prefer to stick to the shadows, using the darkness and element of stealth to their advantage, but not this one.

He's a thief posing as a shipwreck victim, but he's also one of the few villains who's identity was deciphered by Shaggy before Velma had the chance, a rare occurrence in the franchise. The unraveling of the boat-stealing Ghost of Captain Cutler makes for one of the series's best segments overall.

17 Cat Creature

'Make a Beeline Away From That Feline' sees Scooby and the gang investigate a jewel theft by a cat creature who wears a red cape, and it's a quirky fun mystery as always with this show. The episode gets going straightaway with the investigation, and doesn't let up.

Aunt Olivia opens a package containing a strange golden medallion which makes her have dreams that she's a cat creature committing robberies. Turns out the villain of the piece is Dr Bell, who is using Aunt Olivia as a front to commit robberies by hypnotizing her with a golden medallion.

16 The Black Knight

The Black Knight from Scooby-Doo: What A Night For A Knight

Scooby and the gang have gone through numerous changes over the years. They've appeared in TV shows, animated and live-action movies, comics, and video games. They've been t-shirts and toys of every sort.

None of that would have been possible without "What a Night for a Knight," the very first episode of Scooby-Doo, Where Are You? "What a Night for a Knight" introduces viewers to the Black Knight. Two glowing yellow eyes peek out from the visor of his suit of armor, which looks more ridiculous than menacing as he chases the Scooby Gang around. Beneath the helmet, he's just a museum curator trying to protect his art smuggling operation, but the Black Knight is still an icon of the franchise.

15 Redbeard's Ghost

Redbeard's Ghost from Scooby-Doo: Go Away Ghost Ship

Ghosts and spirits of all sorts are a staple of Scooby-Doo, as the gang investigates one supposed haunting after another, and "Go Away Ghost Ship" brought viewers one more apparition: Redbeard's Ghost. He may be something of a forgotten cartoon now, but Redbeard's Ghost sure left an impression on the Scooby Gang.

During his brief time with them, Redbeard's Ghost chains the gang up, forces them to walk the plank, and even makes them cook for him. Magnus, the man beneath the mask, does all this just to disguise the fact that he's been pirating his own cargo as a form of insurance fraud, making him that much more despicable.

14 Apeman

apeman roaring

This episode is all about an Apeman who terrorizes a movie set. Apeman is an underrated villain with a good motive.when he is finally unmasked by Shaggy. It's fairly obvious from the outset who the villain behind Apeman is, but it's an enjoyable mystery nevertheless.

Carl the Stuntman is the villain behind it all and his motive in 'Never Ape an Ape Man'' is his bitterness for not getting the lead in a film. This show might be over 50 years old, but it has great storylines that gives their villains a three-dimensional arc, and this episode stands out as one of the best.

13 The Ghost Clown

The Ghost Clown from Scooby-Doo: Bedlam In The Big Top

Horror is full of creepy clowns, whether they're hiding in storm drains or coming to earth from outer space. The Ghost Clown, introduced in "Bedlam in the Big Top," might not rival those in terms of scare factor, but his grotesque makeup and nefarious deeds still give Scooby-Doo a reason to quiver and shake.

The Ghost Clown successfully manages to hypnotize several members of the Scooby Gang, distracting them long enough to continue with his plan. Whether dressing as a scary clown or forcing others to perform dangerous circus stunts, the Ghost Clown proves he doesn't care one bit about the nerves or lives of others. Thanks to Scooby and pals, however, this clown's reign of terror in the big top is short-lived.

12 Moon Monster

'Scooby's Chinese Fortune Kooky Caper' is probably the greatest episode title of the entire series, and the episode also doesn't disappoint as it features a scary moon monster as one of the series' most memorable villains.

Season three has its fair share of great villains and as the show approaches its end, they add one more iconic villain to the mix. Legend has it the moon monster can turn people into stone, but it's revealed at the end to be a character called Uncle Chin who was manipulating the legend of the Moon Monster to gain his nephew's inheritance. The episode is fun and one of the stand-out ones in season three.

11 Charlie The Funland Robot

Charlie the Funland Robot from Scooby-Doo, Where Are You?

Aggressive speed-walking is the kind of cartoonish trait one might associate with a forgotten Looney Tunes character. It shouldn't be frightening, but when a haywire amusement park robot does it, it is. In "Foul Play in Funland,"

Charlie the Funland Robot is accompanied by a creepy sonar sound that grows more pronounced the closer he draws to survivors, teasing the audience that he is right around the corner. Throw in some glowing, emotionless eyes, and Charlie is a truly creepy villain and much more interesting than the average Scooby antagonist. Not to mention Funland is itself the perfect setting for his antics.

10 The Caveman

"Scooby's Night with a Frozen Fright" introduced Mystery Inc. fans to the Caveman. Awful generic name? Check. Big club? Check. Conan the Barbarian facial structure? Check. What's not to love? Sometimes whole shows need a reboot, and sometimes it's just a character that does.

The Caveman is great and deserves more time in the Scoobyverse. Unlike many Scooby villains that just try capturing the Gang, the Caveman tries bludgeoning them with his club. The Caveman wants to steal an invention that allows communication with marine life, a surprisingly sophisticated motive for someone in a Caveman costume. Ultimately the villain is undone but the same marine life with whom he wishes to converse, a nice touch of irony in an already well-crafted episode.

9 Sea Beast

'The Beast is Awake in Bottomless lake' is the last ever episode of Scooby Doo: Where are You? and it features a worthy final villain in the shape of a sea beast.

The gang decide to go on a trip away to Canada to a place called Bottomless Lake, when Shaggy's doctor tells him to take a hiatus from mystery solving. The trip ends up in the gang doing the opposite of what they went away for-mystery solving. What were they expecting going to a place called Bottomless Lake? The episode is a fitting end to the successful series. The final reveal is credited to Velma who unmasks a woman called Julie who dresses up as the sea beast to scare people away from the lake.

8 The Phantom Shadows

The Phantom Shadows in Scooby-Doo, Where Are You?

Giggling is disconcerting at the best of times. Giggling from a band of green ghosts is worse. When Mystery Inc. attends the reading of a will and is offered the opportunity to inherit a small fortune by staying the night in a haunted mansion, there's no doubt what they will do.

Little do they know the Phantom Shadows of "A Night of Fright Is No Delight" have a different end planned for the evening. The episode is up there with some of the best cartoon episodes, as the ghosts leave a threatening mirror message: "the first is gone, the rest will go, unless you leave the island, and row row row." The Gang gets an extra spooky chill when they then find the Phantom Shadows' final threat: an empty coffin shaped like a dog.

7 The Witch Doctor ("A Tiki Scare Is No Fair")

The poor Scooby Gang can't even take a Hawaiian vacation without some creep terrorizing them. After their guide vanishes, Scooby and the others must investigate, and the trail quickly leads to a cursed village and the Witch Doctor. The setting might be light on good cartoon trivia, but the Witch Doctor keeps things interesting.

The truth that the Witch Doctor is just a poacher trying to get his hands on some local pearls might not be the grand reveal it could have been, but the Doctor makes for a strange and frightful villain while the ruse lasts, making "A Tiki Scare Is No Fair" an excellent Scooby tale, and the Witch Doctor an excellent baddie.

6 Snow Ghost

Close-up of Snow Ghost in Scooby-Doo, Where Are You?

"That's Snow Ghost" is one of the best pun titles in Scooby history, which by itself nets the Snow Ghost a few points. Does Snow Ghost offer up the kind of stylized action that would appease anime fans? Perhaps not. What he offers instead is an absolute willingness to kill the Scooby Gang.

With saws, dynamite, and sheer will in his arsenal, the Snow Ghost does his best to dispatch those meddling kids. Beneath the mask, he is simply Mr. Greenway, a smuggler looking to make a quick buck, even if it means taking Velma's head to do so.

5 Miner Forty-Niner

Miner Forty-Niner confronting Scooby in Scooby-Doo, Where Are You?

Anyone on the road as much as the Scooby Gang is bound to get lost now and then, and get lost they do in "Mine Your Own Business." Naturally, they make themselves comfy in some open rooms at a local motel, which is abandoned on account of it being a ghost town. Then they learn about the ghostly miner haunting the town.

Forget the silly name: Miner Forty-Niner is scary. For one thing, he is huge, towering over the other characters thanks to a pair of hidden stilts. Second, unlike some chatty Scooby-Doo villains, Miner Forty-Niner is silent except for some growls and groans, continuing his dogged pursuit of the Gang in silence. It's enough to give anyone the heebie-jeebies.

4 Ghost Of Mr. Hyde

The Ghost of Mr. Hyde laughing in Scooby-Doo, Where Are You?

The only thing that could make "Nowhere to Hyde" better would be a special appearance by the Hex Girls. Scooby-Doo is no stranger to literary and pop culture allusions, but the Ghost of Mr. Hyde is one of the best.

To be fair, this version of Hyde is a twist on the original, as Dr. Jekyll is only pretending to have transformed into the monstrous Mr. Hyde, using his supposed transformation to cover up a jewelry theft. Worse, Hyde frames Helga, his innocent housekeeper, for the theft, making him one of the most devious villains that the Scooby Gang faces, whether in the original series or otherwise.

3 The Mummy Of Ankha

Scooby and the Mummy of Ankha in Scooby-Doo, Where Are You?

It's fitting that one of the most intelligent Scooby villains is branded with multiple silly nicknames. The Mummy of Ankha, aka "the Big, Bad, and Bandaged," aka the "Creepy Coin Collector" chases after the Gang in pursuit of an ancient Egyptian coin that is the key to an equally ancient treasure.

Despite the apparently limited vocabulary, the Mummy of Ankha is one of the most intelligent villains in Scooby-Doo, Where Are You? In "Scooby-Doo and a Mummy, Too," the mummy disguise is merely a scheme used by the nefarious Dr. Najib. Smart enough to fool people into thinking he could turn them to stone, when in reality his "power" was quick-drying cement, Najib wasn't smart enough to outthink the Scooby Gang.

2 Space Kook

Space Kook flanked by dead trees in Scooby-Doo, Where Are You?

A trail of glowing footprints. A haunted airfield. A skull glaring out of the darkness of a metal suit. The individual elements of Space Kook's story in "Spooky Space Kook" are scary enough but combined they are a true terror for the Scooby Gang. Space Kook is revealed to be a local farmer trying to terrorize his neighbor and snatch up his farm at a discount.

The red and black flicker of his skull would be disconcerting enough by itself, but the Space Kook also has arguably the scariest cackle in the original series. The laugh alone is enough to make one wish the Mystery Machine hadn't run out of gas beside that particular airfield. It might lack awesome Scooby-Doo crossovers, but "Spooky Space Kook" has a winner in its villain.

1 The Creeper

Close-up of the Creeper from Scooby-Doo, Where Are You?

Sometimes a character is recognizable but not that great. The Creeper is both. "Jeepers, It's The Creeper!" begins with him lying in wait on a country road, waiting to ambush a bank security guard who leaves his car to investigate a downed tree.

He incessantly mutters the words "Creeper! Paper!" in reference to the photograph he is searching for, which at least makes it easy to remember his name. There isn't a whole lot of intelligence behind his hulking, Frankenstein's monster appearance, but the Creeper still gives the Scooby Gang a good run, even cutting the power at a school dance and chasing them across the countryside.
