Mauricio di Mauro
Voiced by: Rick Jones (English), Sebastian Schulz (German)
Bubonic's pet. He is a chubby cat with a big appetite. He also likes to brag about his family lineage, which, according to him, goes back to King Oedipus (Mioderlich the Great in the book and in the German dub). He's eager and happy-go-lucky, but much smarter than he seems.
- Accessory-Wearing Cartoon Animal: Wears a blue bowtie.
- Adaptational Intelligence: Mauricio, while still a goofball, is a much more competent spy for the High Council than he is in the novel, keeping his role a secret while still appreciating his master's hospitality, laying low instead of forgetting about his role.
- Acrofatic: He's more chubby than fat but he's still able to climb trees and tentpoles and he can run surprisingly fast. In "Perchance to Dream- Not" he works a trapeze.
- Affectionate Nickname: Is called Kittykins by his master Bubonic.
- Badass Adorable: A cute, cuddly, pot-bellied cat who thwarts his master constantly.
- Beware the Nice Ones: He's very friendly and affectionate. However, don't harm Jacob or the Cozies or you'll be sorry.
- Big Eater: Massive eater.
- Bunny-Ears Lawyer: He loves to goof off but he's one of the most competent members of the High Council.
- Cats Are Mean: Averted. He's the nicest character in the show, and his remarks towards Jacob are mostly playful teasing.
- Cats Are Snarkers: More open and honest than other examples, and not as sharp-tongued as Jacob (in fact, Jacob fits the trope better when he switches bodies with Mauricio), but once in a while he gets in a wisecrack.
- Cats Hate Water: He really hates getting wet.
- Disney Death: Gets himself sent into a painting with Bubonic's great-great-great uncle in "Off the Walls", but fortunately the spell breaks at the last second and Moe is brought back to life.
- Dreadful Musician: He's a notoriously awful singer.
- Four Legs Good, Two Legs Better: Tends to walk on his hind legs.
- Heavy Sleeper: Unlike Jacob, he has difficulty waking up when duty calls at night, as shown in "Perchance to Dream-Not" and "Slowly But Surely". This trait of his carries over from the book.
Jacob: Come on! Duty calls!
Mauricio: Tell it to call back in the morning.
- Heroic Lineage: Claims to have been descended from a medieval knight and likes to brag about it towards Jacob. He also uses this fact to drive himself to do heroic things. Especially when facing dangerous situations. While he eventually revealed in the book that he was just a stray cat, it's not clear if this also applies to this version of him.
- The Hero: Shares this position with Jacob.
- Heroic Sacrifice: In "Off the Walls", he risks being trapped in a painting with Bubonic's great-great-great uncle forever to get him and his pet dragon back into their frames.
- Indy Ploy: Because of the unpredictable spells cast on Megalopolis, he and Jacob are frequently forced to improvise.
- Intergenerational Friendship: With Jacob.
- Interrupted Suicide: In "Colorless Chaos", he goes into a suicidal state once he loses his colors, and walks out into the middle of a busy road. Fortunately, Jacob saves him from being hit by a car.
- In-Series Nickname: Jacob calls him "Moe" once in a while.
- I Was Named "My Name": Bubonic calls him the name he was christened with despite not knowing that he talks.
- Keet: He's eager about everything. Even being a member of the High Council.
Mauricio: At long last, a chance to thwart yet another villainous plan of the evil Bubonic and Tyrannia!
Jacob: Mauricio, you enjoy your job way too much.
- Manchild: He's a childlike adult cat.
- Nice Guy: Kind and caring to his friends.
- Red Oni, Blue Oni: Red to Jacob's blue.
- Right-Hand Cat: Is a pet cat to the evil wizard Bubonic. But this trope is subverted, because he actively foils his master's plans.
- Screams Like a Little Girl: When he gets hit by a trashcan in "By a Hair's Breadth".
- Spell My Name With An S: His name is either spelled with a z or with a c. In "Colorless Chaos" his name is spelled with a z.
- Split Personality: Temporarily gains this in "Wild, Wild Pets", when he's hit by a spell that turns pets feral.
- Still Sucks Thumb: He's shown sucking his thumb in "Simply Irresistible".
- Talking Animal: He's perfectly understood by humans when he temporarily goes DJ in 'Fancy Footwork'.
- Vitriolic Best Buds: With Jacob. He and Jacob argue sometimes but they love each other all the same.
Jacob Scribble
Voiced by: Harry Hill (English), Patrice Dozier (French), Joachim Kaps (German)
Tyrannia's pet. A stocky old raven frequently complaining about his rheumatism. He's stuffy and straight-laced, but is good at heart.
Bubonic Preposteror
A cranky old wizard. He likes to keep things traditional, refraining himself from using modern technology. Therefore, he more or less fits the stereotypical view of an old medieval wizard living in a derelict tower.
- Adaptational Dumbass: He's dim and pathetic compared to how he was in the novel.
- Adaptation Name Change: His name was Beelzebub in the original novel.
- Bald of Evil: He's bald on top.
- Beware the Silly Ones: Actually, could be quite manipulative sometimes, sucsessfully duping Tyrannia into casting spells that would be more beneficial to Bubonic, than to her. Almost never worked against Maggot, though.
- Child Hater: He really hates children.
- Creepy Long Fingers: Downplayed: He's got long bony fingers and is an awful person, but not particularly threatening.
- Dreadful Musician: He's an awful cello player.
- Even Evil Has Loved Ones: Despite being an evil wizard, he does really love his cat Mauricio and his flesh-eating plant Meathead.
- Grumpy Old Man: Fits this trope to a T. He is old, shows contempt for modern technology and yells at children once they interact with him.
- Hero with an F in Good: When temporarily turned good (due to Jacob and Mauricio's intervention), his virtuous actions wreak as much havoc and misery in Megapolis as his previous evil deeds.
- Ineffectual Sympathetic Villain: He's mean and pathetic but lazy and not very bright, and has to be disciplined by Maggot to cast evil spells.
- Jerkass: He's as mean and grumpy as his aunt.
- Lean and Mean: Tall, skinny and nasty.
- Limited Wardrobe: He wears the same clothes all the time.
- Money Fetish: He's a cheapskate who collects rare coins and buys Maurizio cheap cat food.
- Morality Pet: He loves Mauricio and in "Bubonic Plague" doesn't hesitate to save him.
- Talking to Plants: Justified in this case, as the plant he talks to is the flesh eating plant Meathead, who acts more like a pet than a plant.
Tyrannia Vampirella
Voiced by: Kathleen Fee (English), Manon Straché (German)
Bubonic's aunt. Despite being older than her nephew, Tyrannia embraces modern technology and fashion, to the point of calling Bubonic an old-fashioned relic. Much to Bubonic's annoyance, she also likes loud music.
- Acrofatic: Despite being very obese, she does display some impressive acrobatic feats. Mostly done when she is dancing around the cauldron when cursing the city.
- Adaptational Attractiveness: In the book, Tyrannia was still very fat but she was ugly and had barely any hair. This version is at least homely.
- Adaptational Dumbass: She's rather dim compared to how she was in the novel.
- Child Hater: She hates children as much as her nephew does.
- Didn't Think This Through: Quite often forgot to protect her own property from the effect of the spell.
- Drives Like Crazy: She has no respect for boundaries when driving. In "By a Hair's Breadth" she sent her nephew's cat flying twice.
- Even Evil Has Loved Ones: Like Bubonic, Tyrannia is evil, but genuinely cares for her pet raven Jacob.
- Femme Fatale: Becomes one in "Simply Irresistible".
- Hero with an F in Good: When temporarily turned good (due to Jacob and Mauricio's intervention), her virtuous actions wreak as much havoc and misery in Megapolis as her previous evil deeds.
- Incoming Ham: In "The Night of Wishes" she makes her entrance by sliding down Bubonic's chimney, bellowing greetings and greeting Bubonic with a flying tackle.
- Ineffectual Sympathetic Villain: Like her nephew, she's lazy and not very bright and has to be harshly disciplined into casting evil spells.
- Jerkass: She's a mean quarelling witch.
- Morality Pet: She genuinely loves Jacob and is horrified when a melting spell is cast on him in "Wishful Thinking".
- Older Than They Look: Bubonic is a balding elderly man. Tyrannia is his aunt, but looks like a woman in her 30s-40s.
- Pink Means Feminine: She wears a lot of pink, and her default outfit is a pink dress.
- Talking in Your Sleep: In "Slowly But Surely", she keeps Jacob up all night by doing this.
- Totally Radical: Unlike Bubonic, she embraces modern technology and fashion.
- Unlimited Wardrobe: She wears a different outfit and hairstyle every episode.
Maledictus T. Maggot
Voiced by: Joël Martineau (French), Bert Franzke (German), Vlasta Vrana (English)
The supervisor of the wizards. Every episode, he visits Bubonic and Tyrannia, reminding them of their obligation to curse the city and that the consequences for failing will be severe. True to his word, he always reappears when the curse is broken, punishing the wizards for their failure. Usually, the punishment has something to do with the curse of the episode.
- Adaptational Jerkass: He's noticeably more irritable than his Affably Evil book counterpart.
- Added Alliterative Appeal: Tends to employ this in his speech. Examples include Frustrating Foolish Flops and Bumbling Boneheaded Buffoons. His name itself barely subverts this trope due to his middle initial.
- Beast Man: Primarily resembles a humanoid insect/amphibian of some sort.
- Big Bad: Sort of. While not actively acting against the protagonists, his presence is the only reason they need to act. If he did not command the wizards to curse the city, they wouldn't probably even bother doing it, as they are far too busy with their own hobbies. So this makes Maggot the reason why Mauricio and Jacob have to save the city every time.
- Cool and Unusual Punishment: Is really creative when it comes to thinking up ways to punish Bubonic and Tyrannia.
- Evil Sounds Deep: His voice is deep and sinister. Even more so in the German dub.
- Even Evil Has Loved Ones: Despite being an evil inspector from Hell, he really loves his wife.
- Ghostly Glide: He never seems to walk regularly and rather moves around by floating.
- Henpecked Husband: Despite being a very powerful wizard, his wife seems to be firmly in control with their relationship.
- Insistent Terminology: Insists on being called by his full name Maledictus T. Maggot.
- Mysterious Middle Initial: We never learn what the T in Maledictus T. Maggot stand for.
- Neat Freak: Is turned into one in "Inspector Maggot". As the wizards get tired of him constantly inspecting and punishing them, they use the Wunschpunsch scroll to curse him into inspecting the citizens of Megalopolis. If they do not meet his ridiculously high standards, he will punish them the same way he normally does the wizards.
- Pet the Dog: He seems to have a soft spot for Mauricio and Jacob, even trying once to take them away from their owners under assumption that they would like to live with him and his wife better. (And they actually do).
- Punch-Clock Villain: He's nasty and bullies his subordinates, but really he's just doing his job, as shown in "Life with Maggot".
- Sharp-Dressed Man: More like a sharp dressed insect frog thing. Maggot is dressed as a British business man, complete with suitcase and bowler hat.
- Villainous BSoD: In "Gloom With a View" he shows up to the wizards' house in a catatonic state, mumbling about how much sorcerers' work depresses him.
- Voluntary Shapeshifting: Is able to freely change his form into all sorts of animals and objects. He likes to use this power to startle the wizards by suddenly appearing before them.
- You Have Failed Me: Every episode has him punishing the wizards for failing him.
Auntie Noah
Voiced by: Joanna Noyes (English), Tom Pauls (German)
A wise old tortoise living in the Megalopolis zoo. She is the head of the animal council, a group of animals dedicated to protecting humans from evil wizards. Mauricio and Jacob visit her in every episode to ask for advice on breaking the wizard's newest curse. She always gives said advice in the form of a rhyming riddle.
- Big Good: She's shown to have some magical abilities of her own, such as appearing to Mauricio and Jacob in a dream in "Life with Maggot".
- Canon Foreigner: She has no counterpart in the book.
- Eccentric Mentor: Is sometimes oblivious to the wizard's latest curse, even when the effects are right before her eyes. Also tends to forget which riddle applies to which curse. But her wisdom always saves the day.
- Gender-Blender Name: She's a female tortoise named Noah. This is based on her French name, Antinoé.
- Humans Are Morons: When wizard's spell started to turn peoples into animals, Auntie Noah actually considered this an improvement.
- Figure It Out Yourself: She never directly tells Mauricio and Jacob how to break the curse. Instead, she gives them a riddle of which the answer contains the solution for breaking the curse. A large part of the episode has Jacob and Mauricio trying to find out what the riddle means.
- Named After Someone Famous: Told the heroes she was named after the biblical Noah. You know, the one with the ark.
- Non-Mammalian Hair: Despite being a tortoise, she has rather long white hair growing on her head.
- Proverbial Wisdom: A wise old mentor who speaks in rhyming riddles.
Oakfoot
The fireman's dog. Sometimes helps Maurico and Jacob on their missions.
- Dub Name Change: "Florian" in German.
- Nice Guy: He's a nice, easy-going guy who occasionally helps Mauricio and Jacob on their missions.
The Cozy family
The next door neighbors of the wizards. A typical family consisting of a father, mother, oldest daughter Kelly and the youngest son Pip. They appear in almost every episode, becoming the victim of the wizards' latest curse, allowing the audience to see its effects.
- Captain Oblivious: No matter how weird things get around them, they never seem to catch on something is seriously wrong. One example has the wizards turning the entire city into a desert. The Cozy family were planning to go to the beach that day and sit the entire episode in the sand, wondering where the water went.
- Dub Name Change: Kip is named Karl in Germany, and Kelly is Koko. Kip is named Pim in the Dutch dub (no doubt because "Kip" is Dutch for chicken).
- No Name Given: Kip and Kelly are the only ones in this family whose names are known. The father and mother don't seem to be named at all.
- Nuclear Family: They are just your typical family consisting of two married parents and a son and daughter.
- Papa Wolf: When the wizards cast a spell that turns the men against the women and vice versa, father Cozy singlehandedly breaks free from said spell when his daughter seemingly gets attacked by a feral cat. Said cat was actually Mauricio pretending to be feral as the Papa Wolf trope had to be invoked to break the curse.
- Pink Means Feminine: Kelly wears a pink shirt.
- Unlucky Extra: Their only role in this show is to be the victim in the wizards' latest scheme.
