# List of Courage the Cowardly Dog characters

This is a list of characters from the Cartoon Network animated series, Courage the Cowardly Dog.

## Main characters
### Courage

    Voiced by Howard Hoffman (pilot) and Marty Grabstein (series; "The Fog of Courage"; Straight Outta Nowhere: Scooby-Doo! Meets Courage the Cowardly Dog)
Courage is the titular character and protagonist of the series. He is a kind, yet easily frightened pink-furred beagle who was abandoned as a puppy after his parents were sent into outer space, but was adopted by Muriel Bagge. Her husband Eustace regularly mistreats him. Ironically, given his name, Courage is a genuine coward and he often expresses his distress with over-the-top, piercing shrieks. Regardless, he still goes to great lengths to protect his owners. In the end, he often gets injured, sometimes quite brutally, and only survives through his determination and/or pure luck. Despite his cowardice, Courage is very clever and resourceful when the situation demands it, outsmarting the villains most of the time. He also often displays super strength, carrying Muriel and Eustace with relative ease. Aiding him in saving the day is a self-aware, sarcastic, and seemingly omniscient computer that he keeps in the attic. He got his name when Muriel found him as a puppy alone in an alley and remarked that he must be quite brave to be there by himself.

### Muriel Bagge

    Voiced by Howard Hoffman (pilot) and Thea White (series; "The Fog of Courage"; Straight Outta Nowhere: Scooby-Doo! Meets Courage the Cowardly Dog).
Muriel Bagge is Courage's owner and Eustace's wife. She is a plump, kind, hardworking Scottish elderly woman who took Courage in when he was an abandoned puppy. Muriel often carries a rolling pin that she hits Eustace with whenever he harasses Courage. She also likes tea and usually tends to her garden, as well as being an accomplished sitar player. Muriel also has a great fondness for cooking; however, her recipes tend to include an excessive amount of vinegar, much to the distaste of both her dog and husband. Most of all, she loves sitting in her rocking chair with Courage on her lap and watching television. Due to her kindness and sweet nature, Muriel is an easy (and often attractive) target for villains. The crossover movie Straight Outta Nowhere: Scooby-Doo! Meets Courage the Cowardly Dog was White’s final role before she died of liver cancer in 2021.

### Eustace Bagge

    Voiced by Howard Hoffman (pilot), Lionel Wilson (Episodes 1–33), Arthur Anderson (Episodes 34–52), Wallace Shawn ("The Fog of Courage"), and Jeff Bergman (Straight Outta Nowhere: Scooby-Doo! Meets Courage the Cowardly Dog)
Eustace Bagge is Muriel's husband. He is a skinny, greedy, cynical, and sarcastic elderly man who is obsessed with his vintage truck. Eustace wears glasses identical in appearance to Muriel's. His brown hat shields his glistening bald head. Eustace is the current owner of the farmhouse, which was previously owned by his now-deceased brother Horst. Eustace regularly yells at Courage and calls him a "Stupid dog!" He regularly dismisses Muriel as well, but he still does love his wife, as evidenced by his concern for her well-being in a few episodes, like "The Demon in the Mattress".
Lionel Wilson originally voiced the character, but left midway through the third season due to illness (and eventually died five months after the show ended) and was replaced by Arthur Anderson. However, many vocals and sounds of grunts, laughs, screams and catchphrases from Wilson have been used while Anderson was recording. In the 2014 short titled The Fog of Courage, Wallace Shawn replaced Anderson as the voice of Eustace. In the crossover special with Scooby-Doo, Straight Outta Nowhere: Scooby-Doo! Meets Courage the Cowardly Dog, veteran voice actor Jeff Bergman plays Eustace.

## Supporting characters
### Courage's Computer

    Voiced by Simon Prebble (series), Paul Schoeffler ("The Fog of Courage"), and Jeff Bergman (Straight Outta Nowhere: Scooby-Doo! Meets Courage the Cowardly Dog)
Courage's computer who speaks with a British accent and gives him advice on how to deal with crazy situations. Located in the farmhouse attic, he is very cynical and sarcastic towards Courage and has a habit of regularly cracking jokes in any situation. The Computer also appears to often provide Courage with sarcastic and unhelpful advice, but is nevertheless supportive of him.

### Dr. Vindaloo

    Voiced by Paul Schoeffler
Dr. Vindaloo is an Indian doctor with a thick accent, whom Eustace and Muriel see when something is wrong. He is one of the few characters in the series who can perfectly understand what Courage is trying to say. He diagnoses his patients as not having serious problems or that there is nothing that he can do, but has, on occasion, been a great help. He often quotes “There’s nothing to worry about. Nothing at all. But, there's nothing I can do.” when questioned about certain health conditions or situations.

### Shirley the Medium

    Voiced by Mary Testa
Shirley the Medium is a small green Chihuahua garbed as a stereotypical Gypsy fortune-teller who resides in a dilapidated caravan. She has a strong dislike of Eustace (whom she always refers to as "the stupid one") because of his greed and selfishness. Due to this she often places Eustace under curses to get him to be a better person. Shirley is one of Courage's three confidants, the others being the Computer and Dr. Vindaloo, and helps him occasionally by casting and reciting spells and playing the saxophone in-between verses.

## Major villains
### Katz

    Voiced by Paul Schoeffler
Katz is a sadistic red tabby cat with a British accent. He is Courage's nemesis and the show's most recurring antagonist, though Muriel and Eustace consistently fail to recognize him. He specializes in scam businesses and is extremely sadistic. Many of his businesses involve torturing or outright killing his customers; for example, in "Night at the Katz Motel," he fed his motel residents to flesh-eating spiders, and in "Klub Katz," he transformed the vacationers into machines to fight for him gladiator-style. All of his businesses enforce a strict "No Dogs Allowed" policy, forcing Courage to sneak in. He often challenges Courage to ironically banal games such as wall-ball and staring contests, which Courage invariably loses; nevertheless, he is always defeated in the end. Unlike the rest of the series villains, he is frequently accompanied by his own theme, which consists of a sinister hip-hop beat.

### Le Quack

    Voiced by Paul Schoeffler
Le Quack is a French-accent duck con-artist who first appears early in the show's first season, in which he has a fake amnesia-specialist license; he comes to the Bagges' house when Muriel suffers from amnesia. Since then, he frequently returns and manages to dupe Courage's owners into helping him commit crime sprees. Le Quack is also shown to be capable of escaping custody such as when he was first arrested, crashing the police car in the process, and later causing a fire at prison.

### Di Lung

    Voiced by Tim Chi Ly
Di Lung is a Chinese inventor who first appears in the episode "Hothead". He is very inconsiderate and rude and usually gets caught in the middle of the chaos happening in Nowhere, prompting him to shout his catchphrase of "Watch where you're going, ya fool!", which is a running gag in the series, because he uses said phrase hypocritically, when he is clearly in the wrong despite claiming that the other person is wrong. He is the inventor of Mecha Courage. Di Lung also has two aunts: one good and one bad, who are both the Empresses of China; thus, this could make him royalty.

### Ma Bagge

    Voiced by Billie Lou Watt
Ma Bagge is the mother of Eustace and Horst and Muriel's mother-in-law, who shares a love-hate relationship with the former, usually calling him "Stupid Boy". She lives in a trailer and is the widow of Icket Bagge (Eustace’s father). Like Eustace, she is actually bald but wears a wig and looks almost identical to her son, but much shorter, along with being insecure due to being bald, but she does have her teeth. It is learned that Ma and Horst's ill treatment was part of Eustace's negative personality. She tends to treat Courage kindly whenever Eustace is around, possibly because she knows it annoys him, though she also has a love-hate relationship with him, and calls him "Stupid Dog" just like Eustace does. She's also the owner of Growth Industries, a company that produces wigs and experiments on certain people with a rare blood type, one that Muriel has.

## Minor villains
### Benton Tarantella and Errol Von Volkheim

    Voiced by Peter Fernandez (Benton) and Paul Schoeffler (Errol)
Benton Tarantella (a pun of Quentin Tarantino) and Errol Von Volkheim (a pun of Erich Von Stroheim and Errol Flynn) are a zombified duo of film directors. They would pose as ordinary movie producers to lure unsuspecting victims to their fates, killing them in the process as part of their ‘film’.
Tarantella returns in the episode, "Angry Nasty People", when he uses his camera to capture Eustace's nastiness towards Courage and Muriel, creating another version of Eustace named "Mr. Nasty."

### Buschwick

    Voiced by Andre Sogliuzzo
Buschwick (though he bans people from calling him that, ordering everybody to refer to him as simply "Schwick") is a cockroach who comes from a New York City neighborhood of the same name. He appears in the episode "Courage in the Big Stinkin' City" and invites Muriel, along with Courage and Eustace, backstage at Radio City Music Hall that is close to Rockefeller Center in Midtown Manhattan in New York City, New York so that Muriel can rehearse for a sitar concert which was a prize that she won in a contest. Bushwick sends Courage away to retrieve an evil package, threatening to sentence Muriel to be a victim of an unseen monster behind a locked door if he does not receive the package before curtain time, adding that the dog better not get the police involved, which also results in Muriel's demise. Although the dog recovers the package, Schwick finds that its contents are damaged, frustrating him and causing him to release his pet from its cage. The creature eats Eustace, but Courage and Muriel attend the concert while Schwick is arrested by a New York City Police Department police officer

### Buschwick's pet

Buschwick's pet is an unknown creature that is locked behind a mousehole door in his rehearsal room. The unseen monster is responsible for the demise of previous visitors who entered the room (their bones are visible inside) and he warns Courage to recover his package before the curtain rises, without involving law enforcement, otherwise, he will release the monster on Muriel. Courage acquires the item, but the insect finds that the contents are damaged, causing him to release the creature, attempting to kill Muriel. Courage and Muriel escape unharmed, but the creature devours Eustace.

### The Chicken from Outer Space

    Voiced by Howard Hoffman
The Chicken from Outer Space is the show's first villain, introduced by the pilot episode of the same name. His eggs are unlike regular chicken eggs as they have red spots with a red yolk, are mutagenic and whoever eats them will turn into one. In his first appearance, he tries to take over the farm, he lays eggs in the chicken coop which are eaten by Eustace, and ends up being shot by his laser gun, turning into a headless roast chicken. He later returns in "The Revenge of The Chicken from Outer Space" where he wants to use a plunger to rip off Courage's head and put it on his roasted body. He ends up ripping off Eustace's head and tries to destroy Courage but is then blown up in his spaceship when a rocket blasts into it. In "Son of the Chicken from Outer Space", his three-headed son is sent to Earth to avenge him and kill Courage. Unfortunately, like their father, they are no match for the timid dog and fear that they will never be able to go home until Courage is dead. Feeling sympathy for them, Courage helps them by taking fake pictures to make it look like they succeeded in killing him and fooling their mother into thinking that their mission was a success.

### The Snowman

    Voiced by Paul Schoeffler
The Snowman is a talking snowman believed to be the last of his kind due to global warming. In his first appearance, he tries to steal Eustace and Muriel's "anti-melting" gene. He returns in the episode "The Snowman's Revenge" where he turns the farmhouse into the West Pole and freezes Courage and his owners, however, he reveals how he lost his home and friends. After Courage restores his homeland and his friends, he returns home to reunite with them. He has a voice pattern like that of the Scottish actor Sean Connery.

    Voiced by Paul Schoeffler
The Cajun Fox is an orange sunglass-wearing fox obsessed with cooking who appears in "Cajun Granny Stew" and "Ball of Revenge".

### Freaky Fred

    Voiced by Paul Schoeffler
Freaky Fred is Muriel's nephew who was sent to the "home for freaky barbers", due to his obsession with cutting the hair of people or animals to the point that they are bald. He speaks in poems and rhymes often repeating the word ‘naughty’ when describing certain situations.

### The Clutching Foot

    Voiced by Paul Schoeffler & Arnold Stang
The Clutching Foot is a foot fungus that Eustace contracts before mutating into a sentient being. It resembles a giant purple left foot with heads for toes and acts as if it were a stereotypical criminal mob, with the big toe as the kingpin, and the smaller toes as his goons. It orders Courage to carry out crimes during the episode. It is later defeated when Courage licks it after researching and finding that its main weakness is dog saliva.

### Dr. Gerbil

    Voiced by Guy Paul
Dr. Gerbil is a gerbil who speaks with a Southern accent, who has gone mad due to being experimented on and being trapped by his previous owners.

### Dr. Žalost

    Voiced by Paul Schoeffler
Dr. Žalost is "the greatest unhappy scientist who ever lived" who lives in a giant, moving tower. He lives with his assistant, Rat, whom he constantly asks for a hug. He demands 33⅓ billion dollars from the city of Nowhere to fund his "Unhappy Cannonball" project, only to be brushed off by the city's officials as a scam artist. In retaliation, Žalost attacks the city by firing unhappy cannonballs from his mobile tower, making the citizens of the city depressed and unproductive. Despite receiving his money in the end, he refuses to return the inhabitants of the city to normal, as he is jealous of the happiness of others. He then turns his attention towards the Bagge family, determined to inflict sadness and depression on all of the inhabitants of Nowhere. His name Žalost is a word of Croatian, Serbian, Bosnian, or Slovenian origin meaning "sorrow" or "sadness".

### The Goose God

    Voiced by Paul Schoeffler
The Goose God is a goose who came down from the heavens to search for the woman of his dreams, and ended up falling in love with Muriel, whom he competed with Courage and Eustace to make his wife and queen (even though Eustace is completely unaware this is happening).

### Jeeves Weevil

    Voiced by Michael Allinson

He succeeds at sucking out Eustace's life.

### The King of Flan

    Voiced by Jorge Pupo
The King of Flan is an overweight man with a Spanish accent and the proprietor of a company that makes flan.

### King Ghidorah

This is a 3-headed dragon that is not a true villain but is present in 'Courage in the Big Stinkin' City' as a creature hidden behind a door inside an apartment block that Courage enters to search for a package for Schwick. It is presumably a reference to the Godzilla franchise.

### King Ramses

    Voiced by series creator John R. Dilworth
King Ramses is the ghost of a pharaoh from ancient Egypt. Two cat grave robbers steal a slab (decorated with images of King Ramses and pictures corresponding to each of his three curses) from his tomb and flee to Nowhere, but Ramses appears and demands the return of his slab. They refuse, so Ramses summons a swarm of locusts. He later attacks the farm when Courage finds the slab and Eustace refuses to return it after discovering it is worth a fortune, summoning a flood of water, a loud record player, and locusts. Eustace finally gives in and Courage throws the slab out of the house. After Eustace reclaims it, Ramses unleashes one final curse that imprisons Eustace in the slab as punishment for his greed as it is returned to Ramses's crypt the next day.

Thousands of years later, Professor Frith accidentally resurrected the Mummy. After attacking him, the Mummy decided to take revenge against Eustace and Muriel. He mistakes them for the princess and poobah. With some setbacks, the Mummy finally arrives at the farm where Courage hypnotizes Eustace and Muriel into thinking they are the Mayan Princess and the Poobah. After recreating the situation from thousands of years earlier, Courage surmised that the Baker was framed by the Poobah.

### Cruel Veterinarian

    Voiced by George Hall
The Cruel Veterinarian is the main antagonist of the Courage the Cowardly Dog episode, "Remembrance of Courage Past". He is responsible for separating Courage from his parents as a puppy under the guise of a veterinary consultation. Manipulating Courage’s parents into talking with him privately, he traps them and locks them in a rocket ship as part of a twisted experiment to breed “space dogs.” Courage tries to save them but is chased off by the vet and helplessly watches as his parents are launched into space.
Years later, a still-traumatized Courage is taken to the same veterinarian by Muriel and Eustace. Recognizing the vet, Courage uncovers his sinister plan to repeat the experiment—this time with him as the subject. The vet traps Courage in a rocket and, when discovered, also captures Muriel and Eustace to prevent them from exposing his operation. He proclaims his belief in breeding dogs in space as the future of canine evolution. However, Courage thwarts the plan, rescues his owners, and traps the vet in the rocket instead. The rocket launches with the vet aboard, seemingly ending his cruelty.
In the episode’s conclusion, the vet’s rocket crash-lands on a distant planet where the dogs from his previous experiments, including Courage’s parents, have survived. Realizing his experiment failed, the vet nervously laughs before the vengeful dogs drag him off-screen and presumably maul him to death. His screams of pain mark his fitting end.

The Weremole is a mole similar to a werewolf but much smaller, yet just as fierce. It has a taste for rabbits and people and if a person is bitten by the weremole, they become one themselves. Its bite does not affect other creatures. The only way to reverse the transformation is to feed one of the weremole's hairs to the victim. The weremole bites Muriel on the hand and when the moon is full she transforms into a weremole. Courage and Eustace team up realizing that they are in more trouble than they thought. Courage and Eustace defeat Muriel when Courage drops one of the original weremole's hairs in Muriel's mouth, and Muriel returns to normal.

### The Windmill Vandals

The Windmill Vandals are a group of 4 horsebacked Vandals who once plagued the land of Nowhere. The farmer who once lived in the farmhouse where the Bagge family now resides constructed the windmill next to the farmhouse, and inscribed several runes, one on each blade of the windmill, to keep the Vandals away. In the episode in which they appear, the windmill breaks, and the Vandals appear as wraiths to come and destroy the farmhouse (even though there were other instances where the windmill was damaged throughout the show and the Vandals did not appear). The mill is repaired and broken several times, until finally it is fully fixed, and the Vandals banished forever more.

### Noble and Hope

    Voiced by Gerrianne Raphael & Paul Hecht
Noble and Hope are Courage's parents whose appearances resemble Courage's, except his father had a mustache and his mother wore a hat with a flower on top and holding a blue purse. Not much is known about his parents or even their names during the series, although Courage's father was called Henry during one of the flashbacks, as they were seen only in the episode "Remembrance of Courage Past" centering on flashbacks to his parents in the veterinarian's office, where Courage last saw his parents. They were launched into space by the Cruel Veterinarian. Courage avoided a similar fate by escaping through a garbage chute, where he was found by Muriel. The Cruel Veterinarian was trapped (by Courage, during the vet's failed attempts to send him, Muriel and Eustace into space) in the rocket, and was launched in space, crash-landing on the planet where Courage's parents and other dogs resided.
In the prequel pilot Before Courage, their names were revealed to be Noble and Hope.

### Kitty and Bunny

Voiced by Barbara McCulloh & Lori Ann Mahl

They appeared in the episode "The Mask" where Bunny is held captive by her abusive boyfriend Mad Dog and Kitty tries to save her, unintentionally getting help from Courage even though he's kept in the dark about the situation and is terrified of Kitty. At the start of the episode, Kitty obscures her face with a mask and believes that all dogs are evil; as a result, she physically attacks Courage several times while staying at the Bagge house.

Courage later rescues Bunny and defeats Mad Dog and his gang. Bunny kisses Courage on the cheek and Kitty awaits Bunny at the Amtrak passenger train's rear, where they both reunite.

Courage tries to rescue Muriel, only to find that the duck brothers were planning a rescue mission of their own (to save the other duck brother, who has been captured by the United States Government and is about to be made into dinner.) Courage volunteers to be mind-controlled instead, and they save the third brother. The three duck brothers reunite and leave. Two of the brothers make a cameo appearance in "Ball of Revenge", where they play guitars and perform as the half-time show.

### The Magic Tree

    Voiced by Peter Fernandez
The Magic Tree is a magical tree that Courage grows, capable of making ideas and dreams come true. It can also talk. It grants wishes, whether they are good or bad, and it ends up granting a wish for Eustace which causes Muriel's head to swell up. Eustace then considers it a threat and decides to chop the tree down and Courage has to defend it for three days to cure Muriel. Although Eustace had a bit of sympathy, he chose to cut it down anyway despite its warnings of what would happen if he did. After the tree has been cut down and before it dies, it tells Courage how to cure Muriel. The tree had the last laugh against Eustace as the episode ended with Eustace's head swollen up just like Muriel's had been in retaliation for cutting it down.
