Voiced by: Paul SchlofflerA fox very reminiscent of a certain Looney Tunes character. Only the fact that he's a fox, has shades, and actually would have gotten his prize if it weren't for a slapstick chase with a certain cowardly dog.
- Accessory-Wearing Cartoon Animal: Wears oversized sunglasses.
- Affably Evil: He generally sports a relaxed and laid-back personality, though he sometimes becomes demented when his goals are in danger
- Amusing Injuries: All part of the episode he's in being a Looney Tunes-esque take of the show.
- Born Unlucky: HE thinks he's Born Lucky. He's wrong.
- Butt Monkey: It goes hand-in-hand with being a Wile E. Coyote Expy.
- Cartoony Eyes/Sphere Eyes: An exaggerated example. Just one of his eyes is as big as his head. No wonder he wears those shades.
- Catchphrase: "Whoo yeah!"
- Cool Shades: To cover his comedically oversized eyeballs.
- Cordon Bleugh Chef: Despite the fact that the recipe sounds like a list of what one would throw into witch's cauldron, his Cajun Fox Stew is apparently superb.

- Lean and Mean: One has to wonder how often does he savour the recipes he concocts.
- Leitmotif: His is a cheery harmonica and washboard tune.

- Sinister Shades: They cover his bulging, oversized eyes.
- Small Name, Big Ego: Luck man luck.
- Southern Gentleman: Very polite and genteel for a villainous man-eater.
- Strong as They Need to Be: Throughout the episode, he has no trouble lifting Muriel above his head and running at full speed. At the end, he has trouble just lifting Muriel into the pot. Which happens to be what leads him to not winning.
- Sunglasses at Night: The entire cartoon he's in takes place in a day, but he's seen without them only a few times, even in his den.
- To Serve Man: His attempt to stew Muriel is what drives the plot of his episode.
A shadow of an evil man that passes away thus letting him free. After becoming free he haunts the basement of Courage's Home, but secretly has a passion of becoming a Star.
- Dark is Not Evil: He likes scaring people, but doesn't actually do anything malevolent.

A big, hairy, misunderstood monster who needed Courage's help to evade an angry mob.
- The Big Guy: To Courage, once they finally become friends.
- Bigfoot, Sasquatch and Yeti: Duh.
- Dark is Not Evil: Not a bad guy at all, just a misunderstood monster.

- Gentle Giant: He seems to have the mentality of a young child.
- Raised by Wolves: Inverted—he was apparently raised by, or at least now lives with, an old human woman who considers him to be her son.
Demon in the Mattress
Demon described as Exactly What It Says on the Tin. When someone sleeps on the bed, he possesses their body by making their skin green, and their hair red. He can only be ousted by an incantation.
- Card-Carrying Villain: Considering he's a demon whose only purpose seems to be possessing people who buy the mattress, he's really got no choice but to be this.

- Who Writes This Crap?!: Eustace recites this part of the exorcism chant with bewilderment:"Kick 'em in the dishpan, hoo, hoo, hoo?!"
Voiced by: Paul SchoefflerMuriel's nephew. At first glance, he just seems to be a crazy, creepy barber. But deep down he's much worse then that. He speaks in his mind and speaks normally in rhymes, but he has basically an obsession (and possibly a fetish) for cutting every single hair off someone. When he cuts Courage's hair he doesn't stop until just the hair on Courage's tail remains.
- Affably Evil: If he weren't someone who seems to have a strange satisfaction in cutting every single hair on someone you would thing he was just a normal creepy barber that thinks/speaks in rhymes.
- Alliterative Name: More like nickname.
- Anime Hair: Has wild, unkempt hair.
- Anti-Villain: Type IV. Unlike most villains in the show, Fred has never any murderous intent with his actions; it's just a sick fetish he can't resist.
- Bald of Awesome: Appears to be slightly balding.
- The Barber: He's a barber for a living.
- Big Ol' Eyebrows: They contribute to his wild appearance.
- Catchphrase: "NAAAUUUUUUUUUGGGHHHTTYYY."
- Cloudcuckoolander: A very mentally disturbed example, but his obsession with shaving people bald, makes him one of the strangest characters in the show.
- Department of Redundancy Department:Eustace: The freak's a barber. A freeeaky barber. With his own freaky barber shop. Where freaky things happen. Freaky barber things!
- Does This Remind You of Anything?: His obsession with shaving heads as a gag looks a lot like a PG analogue of much darker humor.
- Einstein Hair: Indicative of his messiness and ironic for someone who is obsessed with cutting hair.
- Even Evil Has Loved Ones: Subverted with his girlfriend, who left him after he shaved off her hair (he doesn't seem too bothered by this). Implicitly played straight with Muriel, who dotes on him and whom he seems to genuinely like (at least enough to visit her with no apparent ulterior motive, having not known Courage was there until after he entered the house).
- Everyone Has Standards: He refuses to shave Courage's tail, because he considers it "weird."
- Evil Brit: Subverted. He isn't really evil.
- Expy: He is essentially a Lighter and Softer version of Sweeney Todd.
- Fetish: For shaving hair.
- Getting Crap Past the Radar: Fred gives off many creepy vibes, because he kind of acts like a sex offender.
- Green Eyes: Making him even more exotic looking.
- Harmless Villain: The only "threat" Fred poses is just shaving all the hair off someone, and going about it in a very creepy way.
- Inner Monologue: Most of Fred's dialogue is one. He only speaks a couple times to the other characters, and even then it's just short sentences like "you shouldn't play in the toilet," and "Coouuurage...your haaaiiir."
- Leitmotif: The creepy music box in the background.
- The Mentally Disturbed: Was a patient at the "Home for Freaky Barbers." At the end of the episode, he goes back and he doesn't even understand it that way, calling the orderlies "landlords" and the ambulance "private room".
- Nightmare Fuel Station Attendant: Everything about him comes off as extremely creepy.
- Noodle People: He's drawn this way like most normal human characters on the show.
- Nothing Is Scarier: Even though he did nothing but just shave hair, he STILL managed to scare a lot of kids.
- Obliviously Evil: Possibly. He doesn't seem to see his actions as anything worse than "NAAAUUUUUUUUUGGGHHHTTYYY".
- Perpetual Smiler: Wears a constant grin, which adds to his creepiness.
- Poke the Poodle: He was a mentally unstable barber whose major vice was only shaving too much hair off his victims. Still, the show managed to make that really creepy.
- Rhymes on a Dime: Most of his episode is his internal monologue, in which he speaks in rhyme.
- Sesquipedalian Loquaciousness: He has a very refined and poetic speech pattern, which only highlights his insanity and how differently he perceives the world.
- Sharp-Dressed Man: Wears a nice green suit.
- Shout-Out: To Sweeney Todd. He also resembles Beetlejuice.
- Slasher Smile: Although it also looks like a Cheshire Cat Grin.
- Sophisticated as Hell: He speaks in Sesquipedalian Loquaciousness for most of his poem, but one line was "And so I figured 'What the heck?'"
- Traumatic Haircut: Gives one to Courage.
- Verbal Tic: "NAAAAUUUUGHTYYYY..."
- Wicked Cultured: Quite eloquent and well-spoken and dresses in a smart tweed suit.
A creature that moves underground and mainly preys on rabbits. But if it bites a human or perhaps other creatures that survive its bite, they turn into a weremole themselves. The only way to cure a transformation is to get a hair off the original weremole and get it into the affected person's mouth. Presuming you can get lucky enough to get either the Weremole or the victim without getting bitten yourself.
- And Then John Was a Zombie: The Weremole converts Muriel into another weremole, who in turn converts Dr. Vindaloo, who presumably converts or kills Eustace.
- The Brute: As part of the Villain Team-Up in "Ball of Revenge".
- Dumb Muscle: Katz complains about whoever invited a stupid beast like him to join.
- More Teeth than the Osmond Family: And not afraid to use them.
- Our Werebeasts Are Different: A monstrous mole who is just as nasty as any werewolf.
- Red Eyes, Take Warning: The Weremole has red eyes.
- Villainous Glutton: It consumes a whole rabbit bigger than itself, bites Muriel, and is still hungry. It's a ravenous, feral carnivore, so this sort of thing is to be expected.
Voiced by: Will RyanTwo brother ducks who come to Nowhere. They are on a mission to find their third brother. One of the two tends to lay eggs, the other gets annoyed by this.
- Alien Abduction: They kidnap Muriel and Eustace to attach mind control helmets on them.
- Amazing Technicolor Wildlife: They are blue-feathered alien ducks.
- Anti Villains: Type IV, they never meant any harm in putting Muriel under mind control, they just wanted to free their brother so badly.
- Catchphrase: (laid egg) "I told you to stop doing that."
- Evil Brit: Subverted. They're not evil, they just want to get their brother back.
- Feathered Fiend: Although they're at first antagonistic towards Courage, this is subverted by their sympathetic motives, and they had no intentions of any actual malice.
- Jerk with a Heart of Gold: They may argue, but deep down they really care about each other.
- Mind Control: They use helmets to control Muriel, Eustace, and Courage (although willingly for Courage's case).
- Mr. Seahorse: All of them tend to lay eggs despite being male. They also repeatedly lampshade their own confusion about it.
- Sibling Team: It is shown that they work together as much with the third one as with each other. Not that the team is without it problems.
- Solid Gold Poop: The eggs one of them keeps laying at least seem to be pure gold.
Horst's Box Demon
The demon who lived in the box Eustace's brother left behind.
- Ambiguously Evil: This demon looks quite menacing, but after dragging Eustace into its box, Eustace finds that... He has landed in a huge pile of money, much to his joy. The only problem is that he has nowhere to go to spend it.
- Eldritch Abomination: There's know telling what exactly this thing is, and its hands are the only thing that are visible.
- The Faceless: Only its long, gigantic arms are shown.
- Nothing Is Scarier: WHO KNOWS WHAT THIS THING LOOKS LIKE?!

- Anachronism Stew: How does an ancient king get his hands on a record player? Unexplained and Played for Laughs.
- Arson, Jaywalking, and Murder: First he floods your home, then forces you to listen to an annoyingly catchy song, and finally sends a swarm of man-eating locusts after you.
- Catchphrase: "Return the slab, or suffer my curse..."
- Conspicuous CG: Intentionally invoked with King Ramses' character design.
- Cool and Unusual Punishment: His second curse is forcing you to listen to a loud yet catchy song. In-universe, it's treated as being worse than flooding the house.
- Do Not Taunt Cthulhu: Eustace repeatedly refuses to return Ramses' slab. After Ramses casts the three curses, Eustace thinks he's got a chance at keeping the slab. Ramses pulls one last curse up his sleeve: he turns Eustace into an engraving on his coffin.
- Evil Redhead: Has three red hairs that move around, seemingly on their own.
- Extreme Omnivore: His locust swarm can devour an entire house before reaching their victims.
- Grail in the Garbage: The tomb slab was thought to be old garbage by Eustace, but it's only when a TV news report says how much it's worth, does Eustace suddenly want to keep it.
- Historical-Domain Character: He can be any one of eleven pharaohs named Ramses.
- Lean and Mean: Has a skeletal appearance.
- Mummy: He's a mummified pharaoh.
- Nefarious Pharaoh: He can cast one hell of a mummy's curse.
- Non-Malicious Monster: Granted he does destroy Courage's house by cursing them but that's because he just wants the slab to return to their rightful place. The only reason the plague even happened is because Eustace stubbornly refuse to give the slab, regardless of the curse inflicted.
- Our Ghosts are Different: He is the spirit of an ancient king.
The Clutching Foot
Voiced by: Paul SchoefflerMobster-like foot fungus monster that is created from a strange infection that overwhelms Eustace. The Big Toe is the mob boss, while all the rest are followers with no different personalities except maybe for the Pinky Toe.
- The Brute: To itself, oddly enough, as it is a gang of 5 all in one, and does the heavy lifting itself.
- "Yeah, see."
- "Or the fat lady gets it!"
- The Ditz: The Pinky Toe. Compared to the Big Toe who is the schemer and the three middle toes who have no personality, he's a bit slow on the uptake.
- Enemy Without: He was originally Eustace's foot. But in his second appearance, he shows up as his own entity. This is technically impossible, but considering the series...
- Eyes Always Shut: All the toes appear to be squinting.
- The Mafia: Acts and sounds like a mobster from the Prohibition/Depression era.
- No Celebrities Were Harmed: The big toe talks like Edward G. Robinson.
- The Runt at the End: The Pinky toe.
- Stating the Simple Solution: Pinky Toe suggested they Just Shoot Him in "Ball of Revenge", and was reprimanded by the other 4 toes.
- Toilet Humor: Whenever he squeezes Muriel, she farts.
The Hunchback Of Nowhere
A grotesque hunchbacked man with a heart of gold who visited the Bagges one night.
- Amazing Technicolor Population: He's a dark green color, which clashes with his red hair.
- Bald of Awesome: In sharp contast to Eustace. While Eustace takes the mere fact that he's bald as an insult and flies into a rage, in the same scene the Hunchback takes far worse insults with polite grace and serenity.
- Expy: Is a walking Shout-Out to The Hunchback of Notre Dame, right down to being a bellringer as a hobby.
- Face of a Thug: Though he's certainly not really a thug.
- The Grotesque: Is exaggeratedly ugly, to outright Gonk levels - however, his sheer goodness and good-natured enthusiasm propel him into still being a kind of Ugly Cute despite this through personality alone.
- Nice Guy: In fact, one of the nicer characters Courage has met in the entire series. He also holds the distinction of being the only character besides Muriel to stand up to Eustace on Courage's behalf.
- Renaissance Man: He's a musician, an acrobat, and a shadow puppeteer.
- Walking the Earth: His way of living. He leaves the Bagge farm with good feelings seeing that there are still kind people out there.
The Goose God
Voiced by: Paul SchoefflerA god who is Exactly What It Says on the Tin. He desires love and a worthy queen to be wed to. He gets a crush on Muriel and tries to take her as her queen. At least until he hears the sound of the horn of Eustace's truck.
- Anything That Moves: He's a bird god who wants to get with a human, and later a motor vehicle. Which, due to a later Call Back, seems to have stayed a functional relationship. Sounds about right, considering.
- Evil Is Hammy: He talks like a Shakespearean actor and gesticulates like an opera singer.
- Evil Sounds Deep: A rather impressive baritone, as befitting a goose god.
- Expy: Of the Greek god Zeus. He even has the same lust for mortal women.
- Feathered Fiend: A bird who isn't exactly evil, but is definitely a jerk.
- Green Thumb: He can create an endless field of flowers.
- Immortality Immorality: He ultimately decides to kidnap Muriel when he can't when her over, because he feels like it's his right as a god.
- Interspecies Romance: His episode centers around him trying to woo Muriel. He later settles for a pickup truck though. Then again he is a deity, so the goose is merely his chosen form, and the interspecies is between divine and mortal.
- Jerk with the Heart of a Jerk: He refuses to take Muriel's "no" for an answer.
- Jerkass God: He's a deity who feels entitled to whomever he lusts after.
- Large Ham: From his hyper-dramatic soliloquies to his ridiculously showy attempts to impress Muriel, nothing this guy does is subtle.
- Odd Job Gods: He's basically a divine bird-man, who's apparently the God of Gooses.
- Physical God: A cartoony Zeus parody, to be exact. Also a goose for whatever reason.
- Rhymes on a Dime: Not only in his dialogue, but also in the poem and the song he writes for Muriel.
- Shock and Awe: Can form and throw lightning bolts at will.
- Smug Snake: As you might expect from a god, he has nothing but contempt for mortals. With the exception of Muriel.
- Toothy Bird: Has a rather disturbing toothy grin, despite being a goose. Justified in this case, since he's not actually a bird, just a god that looks like one.
- Wicked Cultured: Writes music and poetry and sings opera. Also kind of a jerk.
Queen of the Black Puddle
A siren/succubus-like monster who lives in a black puddle. She lures in men to her puddle and eats them.

- Rapunzel Hair: Her hair is incredibly long.
- Red Eyes, Take Warning: Combined with her outfit, it makes for Black And Red And Evil All Over.
- The Vamp: She seduces Eustace into her lair, but only so she can eat him alive. Literally.

- You Gotta Have Blue Hair: Her hair is a bluish purple.

- Our Zombies Are Different: Like Tarantella, Volkheim retains his intelligence and personality as a zombie, but also gains a taste for human flesh.
- Screw This, I'm Outta Here!: Courage manages to foil their evil plot by editing the film script, so they release Muriel unharmed. Tarantella and Volkheim argue, and then they leave the house on their separate ways.
- Serial Killer: When they were still alive, Volkheim helped Tarantella murder 12 people. Volkheim somehow got paroled though.
The Precious, Wonderful, Adorable, Lovable Duckling

- Feathered Fiend: Yet another evil and wicked bird, much like Le Quack or the Chicken from Outer Space.
- Hoist by His Own Petard: His own rocket that was meant to blast Muriel to the moon.
- Ironic Nickname: He's not actually precious, wonderful, adorable, or lovable. At all.
- Jerkass: He is very nasty towards Courage and Muriel (whenever she isn't looking).

- Happily Married: We haven't seen his wife since his debut episode, though.

- Shout-Out: The Great Eggplant may be directly or indirectly be based on The Great Pumpkin.

Voiced by: Jim Cummings

- Con Man: He tricks people into joining him as actors, with promises of fame and fortune.
- Deal with the Devil: He convinces people to sign on with him, promising to make them stars, but really intending to turn them into puppets.
- Evil Is Hammy: He acts very dramatic, not only because he's a stageowner, but because he's evil as heck.
- Evil Laugh: Of course, this is something of a trademark for Cummings. He lets out a long, powerful laugh as his stage is turning Muriel and Eustace into puppets.
- Evil Puppeteer: A travelling puppeteer who manipulates people into joining him so he can turn them into puppets.
- Hellish Pupils: His pupils are noticeably slit-shaped. They lend him a sinister glare that is absolutely fitting for his wicked personality.

- Ominous Opera Cape: Wears a long purple cape, fitting for such a dramatic stage actor. Of course, it's also fitting considering how evil he is.
- People Puppets: His stage literally turns people into puppets. This is also how he meets his end.
- Psychopathic Manchild: Implied. The way he "plays" with puppet-ified Muriel and Eustace is reminiscent of a cruel kid, and the fact that there are so many unused puppets backstage indicates that he just throws them there when he's done playing with them. Also, he's terrified of ghosts.
- Purple Is Powerful: His cape and collar are purple.
- Sadist: What else do we call someone who enjoys turning everyone he meets into lifeless objects/toys for him to play with, and feels good as the master puppeteer of corpses?

- Yellow Eyes of Sneakiness: His shifty yellow eyes are an early hint that he's bad news.

- Wise Tree: Besides granting wishes, he gives advice to Courage.
A robot from a whole planet of militaristic robots, who acts differently from the rest. Instead of wanting to destroy things, he wants to pick up a hobby/job of making wooden reindeer. He is at first ridiculed for this, but when it turns out to be a great business, he is more accepted when he gets back to his planet.
- Alien Invasion / Robot War: Randy's people invade other planets for a living. He's given the task of finding a planet to conquer in order to prove his worth; so he chooses Earth. He never moves beyond seizing the Bagge farmlands though.
- All of the Other Reindeer: Ironic that he makes them, no. In fact he's also red colored... hmm.
- Companion Cube: His wooden reindeer dolls.
- Disintegrator Ray: His head is a dome that contains a large laser cannon, which he uses to incinerate Eustace multiple times.

An anthropomorphic cockroach who invites the Bagge family to a dusty hotel room in New York City, where just on the wall is a small mouse door that has something in there that is never directly known as all that's left of its victims are bones. Schwick is also a wanted criminal, and to hide his tracks he hires Courage to deliver a present to a scary apartment with rooms full of horrible things (one including a certain Violin Girl).
- Berserk Button: Calling him "Buschwick".
- Big Creepy-Crawlies: An anthropomorphic cockroach.
- Brooklyn Rage: "Bushwick" is also the name of a neighborhood in Brooklyn, New York City.
- The Comically Serious: A large part of his appeal is that he is always speaking in a conspicuous and sinister tone even while participating in a hair-length contest with Eustace or changing a danger sign with a skull to a not be afraid one with a smiling face.
- Con Man: As shady as they come.
- Do Not Call Me "Paul": Not "Buschwick". Just "Schwick".
- Fat Bastard: Fat and very, very much a crook.

The aforementioned baby birds' mother. She picked up Muriel to act as a babysitter for her while she flies off to find a husband.

Quite possibly the worst villain of the entire series, he stands out as Courage's biggest nightmare. Why? This screw-loose "vet" came up with a horrible idea back when Courage was a puppy - abduct dogs and rocket them off to the moon to make them into super breeds of space dogs. Tragically... He captured Courage's beloved mom and dad, and Courage himself, with plans to send them into space. Although Courage's parents came to the rescue, the doctor sealed them up in a rocket with a one-way trip to the moon in store. Courage was too terrified by this predicament to do anything but escape harm through a garbage chute- only to watch his parents be catapulted into space - in tears. Fortunately, a younger Muriel discovered the young pup in the dumpster and gave him a happy home. Many years later, the maniac doctor, albeit considerably older and balder, still continues his twisted plans... but now Muriel and Eustace get trapped in a rocket themselves.
