Billy's family
Harold
Voiced by: Richard Steven Horvitz
Billy's father and Gladys' husband.
- Absurd Phobia: Attack of the Clowns implies that he has a fear of Santa Claus. Though considering Santa's been turned into a vampire about seven times in the past, chances are Harold's phobia might not be that absurd.
- Abusive Parents:
- Surprisingly, depending on the episode, he qualifies as this much more than his wife. Because of his lack of any maturity or intelligence, he's often incapable of behaving anywhere close to a proper parent and is more like his equal mentally. He is capable of childishly mocking his son, for playing with the dinosaur toys in Toys Will Be Toys and is even dense enough to bully his son and ask for his lunch money in The Crass Unicorn.
- His own father comes across as this in the flashback in "Billy Idiot", disapproving of Harold’s love of ballet, even going so far as to yelling “Dancing is for girls!” during Harold’s dance recital just when he was about to attempt the Mabuhay Shuffle, throwing him off balance and publicly humiliating him.
- Autocannibalism: In "Super Zero", while picking his nose, he pulled his own brain out through his nose and proceeded to eat it.
- Berserk Button: Messing with his hair, which is what set him off against that Viking who was wearing Billy's clothes.Harold: Young man! You can be rude, break furniture, run up phone bills, shave the cat, and even harass your mother! But when you mess with the pomp, IT'S GO TIME!
- Big Eater: Once ate a mucus-covered rat (which was Gladys' pet rat Sniffles) alive because he was still hungry after two breakfasts. Another time, he ate over twenty pizzas to test his limits.
- Body Horror: In one episode, it's revealed his brain isn't located in his skull, but in his pompadour. That, and it can speak.Harold: Hey! My brain was in there!Harold's brain: Put me in the freezer!
- Bumbling Dad: Like his son, he often doesn't care about anything and has a small IQ.
- Carpet of Virility: Several episodes tend to show he's a very hairy guy.
- Character Check: Later episodes occasionally reaffirm that's he's slightly saner and more intelligent than Billy. A good example is in "Everything Breaks", where he becomes frustrated by Billy's destructive tendencies.
- Characterization Marches On: Early episodes never portray him as being especially unintelligent, just ridiculously apathetic to the various supernatural things going on around him. Later episodes cement him as an idiot rivaling his son. In fact, as Grim put it best in The Problem with Billy...Grim: You are the problem with Billy! You're where he gets it! It's a wonder the boy can even tie his shoes!
- Closer to Earth: While he's dumber than Gladys post-Flanderization, he's still considerably more mentally stable than she is with what little mental functions he possesses and is quite relaxed around Grim.
- Cloudcuckoolander: One has to wonder why he thought it would be a good idea to kidnap his own son while disguised as a Sasquatch in "Here Thar Be Dwarves!"
- Crouching Moron, Hidden Badass: A former Navy SEAL, according to "Dream Mutt". Aside from that, he's generally tough enough to shave without any shaving cream or even wetting the blade. He just bites down on a piece of wood! There was also the time he wrestled a crazed Viking dressed as Billy.
- Depending on the Writer: Basically just an older version of Billy, meaning usually Harold is astonishingly stupid, but every once in a while he appears more competent, insightful and intellegent than usual.
- The Ditz: Billy got more than just his looks. This applies even before he Took a Level in Dumbass considering he didn't seem to notice that Grim was actually the Grim Reaper!
- Dumbass Has a Point: He immediately figured out Mrs. Pollywinkle was an evil witch just by looking at her when even Mandy couldn't figure it out until it was too late.Harold: Hey Billy you forgot your dance bag in the car-OH MY GOSH! An evil witch is using this ballet school so she can steal the souls of innocent students! And now she's stealing Billy's soul!Grim: Wow. That's pretty good! He got that quicker than you did, Mandy.Mandy: Shut up.
- Everyone Has Standards: He'll gladly give fake notes to kids so they can get out of gym, but he won't give one to Billy because that'd make him a bad parent. That said, he gave a fake note to Junior, his nephew.
- Fat Idiot: He's obese and, while not as stupid as his son, very dumb.
- Flanderization: He actually didn't seem that stupid early on, just lazy and apathetic to the fact that his son was friends with the Grim Reaper. By later episodes, he's almost as dumb as Billy.
- Freudian Excuse: It’s implied his bad parenting stemmed from his relationship with his own father.
- George Jetson Job Security: It's stated in "Big Boogey Adventure" that Harold's been fired from pretty much every single job he's ever had — in fact, Billy claims that Harold starts a new job almost every week and Harold adds that his most recent firing (from a restaurant called "Freckle Burger") was because he had eaten all the paper cups.
- Happily Married: Usually, he and Gladys are clearly happy together, despite the former's stupidity. Though in other episodes, Gladys is so abusive to Harold that it borders on Awful Wedded Life.
- Hidden Depths: In his youth, he was apparently smart enough to get accepted into Harvard University, only to have his acceptance letter stolen by a sentient tree. He was also a Navy SEAL at some point, as well as a world-class ballet dancer.
- Honorary Uncle: Mandy seems to see him as one, considering how she hangs out with him and Gladys more than her own parents. In return, he’s rather happy to see her when she’s around.
- I Call It "Vera": He named his safety razor Jericho.
- Mellow Fellow: While he occasionally takes fairly innocuous things (such as being a rock star and ballet) very seriously, Harold generally just goes with the flow.
- Mr. Vice Guy: For all his stupidity, disgusting habits, and even being kind of a jerk at times, Harold is (overall) a decent guy and is generally presented as a fairly sympathetic character.
- Never Learned to Read: Played for laughs in "Billy Idiot," where he claims to be illiterate.
- Nobody Touches the Hair: He gets furious if someone damages or messes with his hair, as shown when he gets furious at a Viking dressed in Billy's clothes for cutting off his pompadour.
- Noodle Incident:
- It is shown in "Here Thar Be Dwarves" that he once dressed up like Sasquatch, kidnapped Billy, and did something to him that left him with "emotional scars". This might explain why his wife thinks she's had an affair with Sasquatch too.
- In one episode, he alludes to a "diarrhea lawsuit".
- Nostalgia Filter: Wishbones implies he thinks his teenage years were the best part of his life, though he gets his ass whooped several times.
- Odd Friendship: Unlike his wife, he's generally shown to be on good terms with the Grim Reaper.
- Only Sane Man: In the early episodes, before the above-mentioned Flanderization, he was this compared to his wife and son.
- Papa Wolf: Sometimes, he’ll come to Billy’s rescue if he needs it. It’s at its most prominent in "Billy Idiot" where Billy is on the verge of having his life taken away until he shows up.
- Red Oni, Blue Oni: He's the blue oni (more reasonable and grounded) to Gladys' red (prone to having nervous breakdowns).
- Strong Family Resemblance: He looks like an older/fatter version of his son with a black pompadour. A flashback in "Billy Idiot" shows that Harold also bears a resemblance to his own father (Billy's paternal grandfather).
- Took a Level in Dumbass: Starts out as seeming reasonably intelligent with occasional indications of having been very intelligent in his past (he was a Navy SEAL at one point and once eligible for admittance to Harvard University), but eventually becomes much dumber (to the point where he's arguably just as dumb as his son, if not dumber).
- Took a Level in Jerkass: In addition to becoming extremely stupid, he’s had no problem selling out his son in later episodes.
- Ugly Guy, Hot Wife: His wife is considered quite attractive by some while he looks almost exactly like an older, fatter version of Billy.
- Unfazed Everyman: Even before he Took a Level in Dumbass, Harold never showed even an ounce of surprise or concern over the various supernatural events occurring around his son, namely his son befriending the Grim Reaper. In fact, he and Grim are generally shown to be on fairly amicable terms.
Gladys
Voiced by: Jennifer Hale
Billy's mother and Harold's wife.
- Anger Born of Worry: Her angry side was born from her worry of Grim, and she learned to not fear him, but destroy him.
- Ax-Crazy: At times she solves problems in an unnecessarily violent way, like when she mistook a hairy Billy for a sasquatch and tried to kill him.
- Doting Parent: She is a caring but overprotective mother to Billy.
- Double Standard: Abuse, Female on Male: In many episodes, Gladys will threaten and even hit Harold. In "Scary Poppins", Harold is even indicated to be terrified of Gladys.
- Fiery Redhead: She has red hair and when angered can even make Grim run away in terror.
- Flanderization: While her first episode establishes her mental instability, several episodes that follow it showcase her acting like a relatively ordinary housewife, suggesting that she only occasionally has nervous episodes. Later episodes turn her into a Stepford Smiler with a permanent Twitchy Eye who is always on the verge of a full-on breakdown.
- Happily Married: She and Harold are happy together, despite the latter's stupidity.
- Housewife: Takes care of the household while her son and husband are away.
- Mama Bear: Mostly in the earlier seasons. If she considers you a danger to Billy, she will do everything in her power to make sure you stay as far away from him as possible. It's one of the main reasons why she hates Grim so much and wants him out of her house.Gladys: (after beating Grim over the head with a mop) STAY AWAY FROM MY BABY!!! He's allergic to the undead!
- Noodle Incident: Apparently, Gladys has had some sort of...less than wholesome liaison with Sasquatch, which is referenced in "Bearded Billy", wherein Billy grows a whole lot of hair and Gladys mistakes him for Sasquatch. Though given that "Here Thar Be Dwarves" had a flashback of her husband dressing as Sasquatch and kidnapping their son while on a picnic, it's possible that she thought that he was actually Harold in disguise.Gladys: (attacking Billy thinking he's Sasquatch) I TOLD YOU IT IS OVER BETWEEN US! WE BOTH AGREED YOU WOULD NEVER RETURN! SASQUATCH! SASQUATCH! STALKER SASQUATCH!
- Obsessively Organized: She goes nuts when things are out of order or untidy.
- Properly Paranoid: With all the dangerous things that happen when they're together, it's no wonder she worries about her son being with Grim.
- Red Oni, Blue Oni: The red oni to Harold's blue oni. She's generally much more emotional and hot-blooded than her husband.
- Self-Serving Memory: She remembers the circumstances that led her to leave a little differently than they actually happened.note
- Stepford Smiler: Type 3. She tries to maintain a sense of normalcy and care for her family but is always close to going over the edge because of Billy's antics. That smile ends up being frozen and forced much of the time as a result.
- Took a Level in Jerkass: In her first few appearances, she was a paranoid, but very well-meaning woman who tried to defend Billy, even if she didn’t realize the full picture. In later episodes, she’s become a lot more aggressive, lashing out at her husband and son a lot.
- Twitchy Eye: Her eye twitches whenever something goes wrong or the supernatural happens.
- Ugly Guy, Hot Wife: She is considered quite attractive by some, while Harold looks like an older/fatter version of their son.
- Women Are Wiser: Subverted — though certainly more intelligent than her husband, she's also mentally unstable and prone to fits of homicidal rage (which she appears to have passed on to her son).
Aunt Sis
Voiced by: Grey DeLisle
Harold's sister and Billy's aunt, who later marries and starts a family with Nergal at the center of the Earth.
- Admiring the Abomination: She falls in love with Nergal.
- Ascended Extra: She first appeared at the end of the episode with Grim's first encounter with Gladys, taking her away from home, only to later had her own focus episode and later marrying Nergal.
- The Cameo: She is briefly seen on a picnic with her husband and son in Underfist.
- Everyone Calls Him "Barkeep": Assuming that "Sis" is just a nickname, we never find out what her real name is — she's named by her relation to Billy and his family (she's Harold's sister, making her Billy's aunt).
- Gag Nose: Her nose is as big as Billy and Harold's noses.
- Happily Married: She ends up marrying Nergal and having a son with him. She even accepts how much of a self-perceived loser Nergal is along with her son.
- Maiden Aunt: Prior to marrying Nergal, Gladys (her sister-in-law) explicitly calls her a spinster when explaining to a curious Billy as to why she "ain't got nobody". Played for Laughs in that she met her true love during a dance contest, and he left her once the contest was over. Gladys explains this was the "Greatest four-and-a-half minutes of her life".
Billy’s Grandpa
Voiced by: Richard Steven Horvitz
Billy’s paternal grandfather.
- Abusive Parents: Insulted his son’s passions. That said, his relationship with his grandson isn’t touched, so it’s not clear whether he’s a Gruesome Grandparent.
- He-Man Woman Hater: Implied, given that he told his son that dancing was only for girls.
- Strong Family Resemblance: He’s basically an older Billy with something of an Irish/Scottish accent.
- What the Hell Is That Accent?: Speaks with a vaguely Irish/Scottish accent.
Mandy's family
Mandy's Parents
Claire
Phil
Voiced by: Dee Bradley Baker (Phillip), Vanessa Marshall (Claire)
Mandy's parents. They are utterly terrified of her.
- A Day in the Limelight: "Scary Poppins" explores their relationship with Mandy.
- Depending on the Writer: Whether they're seemingly oblivious of Mandy's cruelty or completely terrified of her tends to vary from episode to episode. The rare episodes that give them a decent amount of focus tend to stick to the latter.
- Good Parents: For the most part. They love and take care of Mandy despite the horrible treatment they receive.
- Hippie Parents: They seem to be Beatniks, hence why they're so okay with Mandy's abuse.
- My Greatest Failure: Phillip reveals in "Keeper of the Reaper" that wolves tried to adopt Mandy as one of their own after she was born.Phillip: Sometimes, I wonder if we were right to stop them.
- Out of Focus: They're utilized considerably less than Billy's parents. In a deleted scene, they explain they're rarely in episodes because they're afraid of Mandy. Between the two of them, Claire has fewer speaking roles than Phillip.
- Pushover Parents: They cave into Mandy's desires. Part of the reason is that they fear her, but it's implied she has some kind of supernatural control over them.
- Satellite Character: They don't have much characterization outside of being Mandy's parents.
- Those Two Guys: They're mostly seen together. Justified, being husband and wife after all.
- Ugly Guy, Hot Wife: Not as extreme as Harold and Gladys. Phillip would be a relatively average-looking guy if it wasn't for his big nose, while Claire is attractive.
- Wanted a Son Instead: Heavily implied with Phillip. In "Spider’s Little Daddy" he brings Mandy to a Father-Son Picnic, and when he’s called out on it, he gives the excuse that Mandy’s “just One of the Boys”. He also calls her “Son” a decent amount of times in the series.
Endsville Elementary
Students
Irwin
Voiced by: Vanessa Marshall
A nerdy boy and a close friend of Billy's. He has a one-sided crush on Mandy. Later revealed to have monstrous heritage and becomes a crucial member of Underfist.
- Abhorrent Admirer: Mandy can't stand his infatuation. All of the occasions of her reciprocating his feelings or at least not responding to his advances with a punch were either due to magical influence or being unconscious.
- Accidental Hero: Him unintentionally suffering all of Mandy's pranks that were meant for Jack in the Halloween special is what ultimately leads to Jack being defeated.
- Black and Nerdy: Though he's not smart at all, he's black and has a geeky appearance, interests, behaviour, and pastimes. More like black and dorky.
- Breakout Character: Gets steadily more appearances until becoming the main character of Underfist. He also was the host during Cartoon Network's Spot the Block campaign, was a recurring guest star on the Fridays segments and a few holiday marathons.
- Butt-Monkey: Gets a lot of punishment along with Billy.
- Characterization Marches On:
- Early episodes in the Grim and Evil line and the first season of Billy and Mandy simply portray him as Billy's nerdy Satellite Character best male friend, without a trace of the Jive Turkey Stalker with a Crush traits that would come to define him.
- Also within Grim and Evil, he seems to not want anything to do with either Billy or Mandy, a far cry from his portrayal in the series proper as being more of an actual friend to Billy (even if he has his moments) and endlessly pining for Mandy
- The Chew Toy: He's pretty much this show's Kenny variant, as some episodes ended with him getting killed, yet he still comes back for more.
- Dark Is Not Evil: Played with, He's a mishmash of various monsters, but is mostly a harmless and obnoxious nerd. At the very least he has never been actively malicious after his powers developed.
- A Day in the Limelight: Underfist, which was originally intended to be a Poorly Disguised Pilot.
- Dhampyr: He is, at least, 1/4 vampire (his paternal grandfather is Dracula).
- Dogged Nice Guy: To Mandy. She never reciprocates his affections, no matter what he does.
- Dumber Than They Look: He is the resident nerd, in both appearance and behavior, but not in an intelligent way. At best, he's barely smarter than his friend Billy, at worst he's just as dumb as him. He even tried cheating off of Mandy's answers on a test.
- Expy: He has a number of similarities to Steve Urkel in appearance and personality, being Black and Nerdy with big glasses, dorky fashion sense, and a hopeless, unrequited crush on another main character.
- Eye Glasses: His glasses will sometimes contort to his expression. His eyebrows will also overlap his glasses sometimes.
- Four-Temperament Ensemble: The Phlegmatic. He's a nice guy for the most part and doesn't usually seem to be aware of Mandy's faults.
- The Friend Nobody Likes: More or less falls into this role whenever he tags along with the main trio. He's mostly in through Billy (and even he'll mistreat him at times); Grim and especially Mandy don't care for him.
- Geek Physiques: He's very nerdy and has a rather pudgy build.
- Heinz Hybrid: 1/2 mummy, 1/4 vampire, 1/4 human and
22/7 nerd. - Hopeless Suitor: Mandy will never return his feelings.
- Jerkass Ball: Some episodes have him become really mean and even villainous when the plot calls for it.
- Jive Turkey: Later episodes have him pepper his sentences heavily with black slang, most notably "yo". This is Played for Laughs, as it is incongruous with his otherwise nerdy appearance and behavior.
- Mad Love: Keeps a huge crush on Mandy, no matter how many times she rejects him.
- Our Vampires Are Different: He's Dracula's grandson and aside from the traditional vampire powers has also demonstrated being able to fire energy blasts.
- Our Werewolves Are Different: In one episode, Irwin is bitten by a werewolf and transforms later that same night (whereas they typically only transform during the next full moon), not by looking at a full moon, but by looking at a butt on a billboard (apparently mooning is enough). After he transforms, he remains like that into the daylight hours of the next day and acts like a gentle dog instead of a werewolf.
- Red Eyes, Take Warning: His eyes glow red near the end of Underfist. And that's when Bun-Bun realized he was screwed.
- Sixth Ranger: The most frequent character to join the main trio on their adventures, though he has a tendency of dying or otherwise being incapacitated early on in them before anything really gets a chance to happen.
- Stalker Shrine: In "Billy and Mandy's Jacked-Up Halloween", it is shown that he has a shrine where hundreds of pictures of Mandy adorn his walls, all of them featuring Mandy glaring at him or about to attack him since they were clearly taken without her consent. It is one of the most disturbing things in the special.
- Stalker with a Crush: To Mandy. He's hopelessly in love with her and doesn't let anything stop him from following and trying to get close to her.
- Straw Loser: He makes Billy seem cool in comparison. Even after we learn about all of his monster heritage, he still comes off as a useless loser (until Underfist anyway).
- Stereotypical Nerd: Black and Nerdy with Nerd Glasses, a dorky bowtie, he is frequently the Butt-Monkey, The Chew Toy, and The Friend Nobody Likes whenever he tags along with the main group, getting mistreated by Mandy, Grim, and even Billy at times and ending up dead by the end of the episode (only to show up in the next one as if nothing happened). And he is a Dogged Nice Guy turned Abhorrent Admirer and Stalker with a Crush to Mandy, who cannot stand his constant attempts to win her over. He even has a Stalker Shrine dedicated to her.
- Super Power Lottery: Irwin's being a Half-Human Hybrid has given him several powers in Underfist such as: Flight, Hand Blast (called Mummy's Curse), Mummy Wrap, Super-Strength, and Voluntary Shapeshifting.
- They Killed Kenny Again: Has a fairly high tendency of dying whenever he appears, but always comes back. It might have to do with his mummy/vampire heritage.
- Took a Level in Badass: In Underfist, he becomes more competent and is no longer a Butt-Monkey. Earlier, in Billy & Mandy's Big Boogey Adventure, he rescues Mandy and defeats Boogie's crew through The Power of Love. Billy even lampshades it.Billy: Hey! How did Irwin get so cool?
- Used to Be a Sweet Child: Inverted, believe it or not. In "Heartburn", Billy and Mandy play around with Grim's camera that shows the true self of the person on the film. Irwin's heart reveals to be half good like Billy's and half evil like Mandy's, and when questioned, he admits he was an Enfant Terrible at birth before his dad turned him around.
- Verbal Tic: ...yo. Seems inherited; as his dad calls people "dude", and his grandmama calls her loved ones "baby".
- Vocal Evolution: In his earliest appearances, Irwin's voice was stuffier and he had a slight lisp. Eventually, his voice became a bit more clear but still kept a unique sound.
- With Friends Like These...: He's a pretty unreliable friend to Billy, to the point where he almost seems to hang out with him exclusively to be around Mandy. He has also made fun of Billy at least twice, despite seeing how much it upset him, even remarking the first time that it was nice seeing someone else run home crying for a change. The second time when he tried it to win points with Sperg he got shoved aside.
- Yandere: When he got the scythe in "Scythe for Sale", his first thought was to use it to brainwash Mandy and go on a forced date. Everyone makes sure he pays the price in the end.
Mindy
Voiced by: Rachael MacFarlane
An obnoxious and snobby girl from Billy and Mandy's school that is obsessed with proving her worth to Mandy, who doesn't care for her.
- Alpha Bitch: A deconstructed one as a very dim-witted, insecure, and neurotic type. And in the Underfist special she loses the alpha grade because of losing her looks which ups her bitchiness to supervillain take-over-the-world levels to regain it.
- Asshole Victim: Thankfully, she's also one of the show's regular victims of whatever supernatural power is at hand in the episode.
- Bratty Half-Pint: She's definitely a rude and insufferable kid.
- Bullying a Dragon: Picking on Mandy is not a very wise thing to do considering her ungodly amounts of hypercompetence, extreme intelligence and sociopathic tendencies, but for some reason Mindy sees her as no threat.
- Disproportionate Retribution: When Mindy first moved to Endsville, Mandy actually tried being nice to her because she looked alone. She quickly regretted it hearing her chatterbox antics and told her to shut up. Mindy didn't take it well and had become her obnoxious rival ever since.
- Evil Is Petty: She's named so for a reason.
- Evil Redhead: She has ginger-colored hair and is a nasty, downright obnoxious Alpha Bitch.
- Fantastic Racism: Of a sort. "Wrath of the Spider Queen" reveals she doesn't think nerds are people at all, which heavily implies she views anyone she considers a nerd to be subhuman.
- Foil: To her rival Mandy. They have similar names and both of them are mean and rude, but otherwise they are complete opposites: Mindy is a Genki Girl in contrast to Mandy's Emotionless Girl; Mindy is shallow, spoiled, and stupid while Mandy is dark, cynical, and intelligent.
- Genki Girl: A rare evil variant of a girl who's hyperactive which only serves her to make her even more ridiculously obnoxious and put everyone around her on edge.
- Hate Sink: A complete Smug Snake with no redeeming qualities, until she Took a Level in Kindness at the series's end.
- Heel–Face Turn: At the end of "Underfist", she turns against Bun Bun and decides to stop being evil.
- Insufferable Imbecile: She's an airheaded Alpha Bitch who thinks that Paris is a country and Africa is a city.
- Jerkass: She constantly torments Mandy in a verbal manner (in fact, her catchphrase is "LOSER!") and taking it all in stride.
- Licked by the Dog: A subversion in one episode in which this literally happens and she responds by acting even worse than usual!
- Motor Mouth: The reason why Mandy can’t stand her. When they first met as toddlers, she would talk non-stop which lead Mandy to bluntly tell her to shut up.
- The Napoleon: Short-statured and definitely the Alpha Bitch.
- Popular Is Dumb: Demonstrated in "Wishbones".Mindy: But as beautiful and popular as I am, I bet there are some people who've never even heard of me: people in countries like Paris or Toronto, or in cities like Africa.
- Rich Bitch: She is the evil, rich and spoiled queen bee of the school.
- The Rival: She is frequently a rival to Mandy
- School Uniforms are the New Black: Is almost always seen in her school clothes even before the school adopted uniforms even in the later seasons.
- Smart Ball: Her intelligence fluctuates from being almost as cunning and manipulative as Mandy to being a complete airhead.
- Spoiled Brat: Just like Mandy, she has a mother who's always taking care of her, but unlike Mandy's mother, she is one of the jury members at many beauty pageants she takes part in.
- Tomboy and Girly Girl: Girly Girl to Mandy's Tomboy. Mandy is a Little Miss Badass with a dark and unfeminine personality, Mindy is an Alpha Bitch who mostly cares about appearance and popularity.
- Took a Level in Badass: Twice in a row, she's become more competent and dangerous; in both "Wrath of the Spider Queen" and "Underfist".
- Took a Level in Kindness: At the end of both "Wrath of the Spider Queen" and "Underfist".
- Villain Song: She sings "Trick-or-Treater Eaters" in "Underfist" while whipping up a brew to make the candy monsters stronger.
- We Used to Be Friends: Was best friends for a few minutes with Mandy in kindergarten, until Mandy got sick of how much she talked and stopped hanging out with her.
Pud'n
Voiced by: Jane Carr
A classmate of Billy and Mandy's, Pud'n is a very sensitive young boy who is constantly picked on by Sperg.
- Beware the Nice Ones: He got into an epic struggle with a demon rabbit and causes an explosion by squirting the custard out of two éclairs, and he once viciously beat up General Skarr when he thought Skarr was responsible for turning all his neighborhood rabbit friends into monsters.
- Brown Bag Mask: He wears one while competing in a go-kart race with the other kids. He miraculously wins, despite his go-kart being nothing more than a simple red wagon. Mandy ends up unmasking him, and he starts crying like a baby when he sees everyone cheering for him.
- Butt-Monkey: It's very common for him to get hurt or humiliated.
- The Chew Toy: Nothing goes right for him, and when things look like they're going right, either they're actually bad for him or he breaks under the pressure.
- Dub Name Change: His name is changed to Pecas in the Latin American dub.
- The Friend Nobody Likes: His extreme cowardice and habit of bursting out into loud and obnoxious crying whenever he's given any public attention (even if it's positive) render him rather unliked by his classmates.
- In Touch with His Feminine Side: He's weak, seems completely non-aggressive, loves fluffy pink bunnies, and cries at the drop of a hat.
- Kiddie Kid: The most stereotypically childish of the child characters. He likes cute things and often cries like a baby when things go bad for him.
- Raised by Wolves: In one episode, Billy asks Pud'n what he's doing outside so late at night — Pud'n explains that he was raised by wolves and that he and his family live outside. The two wolves that Billy sees (presumably Pud'n's parents) are shown TV and one of them politely waves at Billy, telling him good evening.
- Redheads Are Uncool: He's a redhead who's a frequent target of Endsville's resident bully Sperg.
- Red-Headed Stepchild: He has red hair, freckles, and is Endsville's resident Butt-Monkey and Chew Toy.
- Shout-Out: He has a hairstyle very similar to Dexter's of Dexter's Laboratory.
Sperg
Voiced by: Greg Eagles
The local bully who constantly bullies Billy, Irwin, Pud'n, and other kids to no end.
- Asshole Victim: In "The Nerve", whenever he is assaulted by Billy, he still lacks redeeming qualities no less.
- Berserk Button: Don't talk bad about his mom, especially if it causes her to cry right in front of him.
- The Bully: He is often seen tormenting Billy, Irwin, or other kids.
- Disappeared Dad: His mom only shows up a few times, but we never see his dad.
- Dub Name Change: He is called Valente in the Latin American dub.
- Even Bad Men Love Their Mamas: He's very defensive of his mother.
- False Friend: At the end of his debut episode, Sperg is comforted by Billy after Mandy upsets him. Billy decides the pair should be friends and the duo in a montage are seen hanging out including going cycling, being at an ice cream parlor, and free falling. But just as it seemed Spurg redeemed himself he gives Billy a wedgie, revealing that he hasn't changed his ways and resumes being a bully.
- Fat Bastard: His body is as round as he's a bully.
- Happiness in Slavery: He takes a liking to becoming Nergal Jr.'s pet because the octopus leg that he gets fed tastes better than whatever his mom makes.
- Heroic Sacrifice: Saves the world from alien invaders by using the explosive chip in his head. He manages to bully people without a head.
- Hidden Depths: Despite being a bully and reveling in the lifestyle, he is also shown to appreciate and practice dancing, and isn't ashamed of it.
- Jerkass: He's very mean to most kids, but primarily to Billy, Irwin, and Pud'n.
- Jerk Jock: Possibly as he’s shown to be part of the football team in one episode, though it’s never brought up again beyond that.
- Jerk with a Heart of Gold: In "Billy and Mandy Moon the Moon", he gets a bomb planted in his skull that explodes in a day's time...all while Billy whomps the other aliens mercilessly. What does Sperg do? Make his way to the control room, where he eventually detonates, blasting the alien ship out of the sky.
- The Napoleon: Small in comparison to Grim, and a bully.
- Real Men Wear Pink: He loved to sing show tunes. In "Tricycle of Terror," he expresses a desire to be on Broadway.
- The Ugly Guy's Hot Daughter: Inverted and Gender Flipped, while Sperg is somewhat ugly, his mother is shown to be an attractive woman.
Staff
Ms. Butterbean
Voiced by: Renee Raudman
The teacher of Billy and Mandy's class in Endsville Elementary. She is very apathetic towards teaching, only doing her job for a paycheck and is often seen sleeping in class.
- And Now You Must Marry Me: She gets kidnapped by Fred Flintstone in "Modern Primitves", which causes her to demand that he marry her and give her 2.5 kids.
- Apathetic Teacher: Doesn't give a lick about her job and she is often seen snoring on her desk. And that's her on her good days. Granted, given just how utterly bonkers the world is around her, the quality of the kids she has to teach, and (given what the Principal gives Grim when he becomes a substitute teacher in "Detention X") the downright abysmal pay being at minimum two dollars an hour, it's not without reason.
- Asshole Victim: In "Substitute Teacher" she lets Sperg bully Nergal Junior. Nobody feels sorry for her when Junior kidnaps her and ties her to the ceiling. Thankfully this happens very often...
- Butt-Monkey: Comes with the territory of being around Billy and not cautious and also suffering because of various supernatural phenomena but not an undeserving one satisfyingly enough.
- Four Eyes, Zero Soul: She wears a pair of glasses and is a selfish, callous, and all-around unpleasant person.
- Helpless Kicking: As she is nearly devoured by a talking frog Billy brought to class her legs and butt are seen sticking out of its mouth and flailing.
- Hot Teacher: She's a young, attractive woman. That's just about the only conceivably positive quality she has.
- Jerkass: A callous and shrewish woman who is openly mean and indifferent to her students.
- Jerkass Has a Point: She may be a mean teacher, but with her students, it’s no wonder.
- Last-Name Basis: Justified in that she's a teacher, however, one episode says that her first name is "Eleanor"
Principal Goodvibes
Voiced by: Chris Cox
The principal of Endsville Elementary, and kind of a wuss.
- Beware the Nice Ones: When sufficiently angry, not even Mandy can stand up to him.
- Butt-Monkey: Yet another character on the show who tends to suffer misfortunes on a frequent basis.
- Crazy Homeless People: Slightly subverted. In one episode, it's revealed he lives out of his car, and is very ashamed of it. On the other hand, while he appears relatively sane, his peculiar behavior tends to make people around him uncomfortable.
- Dodgy Toupee: In "Guess What's Coming to Dinner", his hair is revealed to be a wig. Hoss even comments on how obvious it is he's wearing a hairpiece before it comes off.
- Good Is Not Soft: He's a nice, if ineffectual, man. But he's one of the few people to spook Mandy.
- No Celebrities Were Harmed: He sounds remarkably like Paul Lynde.
- Pretty Fly for a White Guy: Becomes a Gangsta Rap-based villain of some sort in "Principal Goodbling And The Hip-Hoppopotamus."
- Putting the "Pal" in Principal: He is generally portrayed as a lame but well-meaning school principal that gives out bad advice to characters that need them, and is generally the Butt-Monkey of whatever supernatural outbreak that happens to be going on at the time.
Others
Hoss Delgado
Voiced by: Diedrich Bader
A spectral exterminator who frequently encounters Grim, Billy, and Mandy in his various exploits, and briefly dates Eris, Goddess of Chaos. Later becomes part of the Underfist team, albeit reluctantly at first.
- Accidental Misnaming: He can't ever remember Irwin's name. In Underfist alone, he calls him "Irving", "Urkel" and "Ivan". He correctly calls him "Irwin" while saving him from the giant pumpkin-headed candy monster... only to go back to forgetting his name a short while afterwards. In "Guess What's Coming To Dinner", he also can't remember the names of either Billy or Principal Goodvibes.
- Art Evolution:
- He's noticeably older looking in Underfist, sporting a beer gut and streaks of grey in his hair. He's also even larger than before and has a chainsaw leg.
- Before that, his head became more angular following his first appearance.
- Anti-Hero: He believes that all monsters are a threat, which causes him to murder any monster he ever sees, even innocent and harmless ones.
- Bad Butt: He's about as much of an over-the-top badass as a kid's show will allow him to be, and almost all of his appearances coincide with violent action set pieces.
- Basement-Dweller: Underfist has him still living with his mother.
- Big Brother Mentor: Acts as a rather half-assed mentor and big brother figure to Billy in a few episodes, and Irwin in others.
- Breakout Character: Became so popular with fans that he starred in the failed spinoff with Irwin in Underfist.
- Bunny-Ears Lawyer: He's a tad eccentric and not very bright, but he is a damn good spectral exterminator.
- Butt-Monkey: Underfist has him suffer several painful injuries as well as moments of humiliation.
- Calling Your Attacks: Depending on the Writer, he will announce the weapon his Swiss-Army Appendage is turning into before using it. Underfist goes a step further by giving them flowery names such as the "mace of total righteousness".
- Characterization Marches On: He's presented as a bit of an incompetent buffoon in his first appearance. In all of his following ones, he is shown to be extremely competent at his job, with most of his humor being derived instead from his excessive and ridiculous monologues.
- Cold Ham: Delivers all of his lines in a stoic voice, but is prone to giving ridiculous (and long-winded) monologues.
- The Comically Serious: His lines are almost always ridiculous, but delivered in a completely serious voice."I've been bitten by ghosts, haunted by mome raths and slapped by vampires... I think I've earned a free hot dog.""Are you stepping in my cornflakes? I'll tell you something about stepping on someone's cornflakes... it's a weird way to eat cornflakes"
- Dating Catwoman: His relationship with Eris, given that he hunts supernatural creatures and she is the Goddess of Chaos.
- Dark and Troubled Past: Parodied. He has an exceedingly long and convoluted one that is also ridiculously lame, involving wetting the bed till he was 33, being raised as a girl for most of his childhood, poking his eye out after running with scissors, and getting constantly one-upped by a traffic cone.
- Destructive Savior: Completely indifferent to the destruction he causes while fighting monsters. He considers completely leveling what is at least an entire neighborhood to be keeping property damage to a minimum.
- Deuteragonist: While Irwin is the main character of Underfist, Hoss is the official leader of the team, and his relationship with Irwin is one of the most central parts of the plot.
- Dumb Muscle: He's far from the brightest bulb, but is an excellent fighter.
- Dub Name Change: From Hoss Delgado to Rene Gado in the Latin American dub, a Punny Name of Renegado (renegade).
- Empowered Badass Normal: He replaced his own hand with an Iron fist that can turn into all sorts of weapons from a gun to a chainsaw. He also replaced his leg with a chainsaw in Underfist.
- Eyepatch of Power: He wears an eyepatch.
- Expy: He's based on Snake Plissken and Ash.
- Extreme Omnivore: It's revealed in a gag Underfist that's he's been eating the book War and Peace when he reveals that he was literally going to finish his novel to Skarr.
- Freudian Excuse: In Underfist, he eventually confesses to Irwin that his intense hatred of monsters comes from being scared by a monster in his closet when he was a kid. Said monster was actually Bun Bun in a witch costume.
- Friendly Enemy: While he's technically hostile towards the main trio due to his hatred of Grim, he tends to work alongside them as an ally just as, if not more often than he opposes them. He's on generally good terms with both Billy and Mandy, and even gets along with Grim when he forgets that he's supposed to be his enemy.
- Go-Karting with Bowser: Despite his hatred of Grim, he's perfectly willing to pal around with him when the situation calls for it.
- Good is Not Nice: He is seemingly the only person in the world who fights supernatural threats besides the main trio, who are more often than not the cause of them, but mercilessly hunts even harmless ones like Jeff and Fred and tends to act like an indifferent jerk to other people. This changes after Irwin saves his life in Underfist, making Hoss realize that there are some good monsters after all.
- Hammerspace: Where he keeps all the random attachments for his hand (his chainsaw, goo cannon, crossbow that fires a chainsaw).
- Hero Antagonist: It varies. His hatred of Grim puts him at odds with the trio on occasion, but he can be an ally just as frequently, if not more.
- Hidden Depths: Despite being a powerful tough guy, one of his favorite things is Pat the Baker, a simplistic baking video game that is also Billy's favorite game. According to him, he never leaves home without it and he and Billy bond over playing it at the end of an episode.
- Hunk: According to Eris. He's so obscenely muscular and hairy that he can be easily mistaken for bigfoot when shirtless.
- Jerk with a Heart of Gold: "Gold" may be pushing it, but beneath his abrasive, indifferent, and self-absorbed exterior lies a guy who genuinely holds some affection for underdogs like Billy and Irwin.
- Lantern Jaw of Justice: Has a perfectly square jaw and is all about defeating supernatural threats.
- Lethal Joke Weapon: One of the forms that his Swiss-Army Appendage takes is a banana, which he uses as a weapon entitled the "banana of justice". While we don't actually get to see just how he uses it, it apparently produces an explosion big enough to destroy an entire swarm of monsters.
- Mundane Utility: Along with the dozens of powerful and useful weapons and gadgets that his Swiss-Army Appendage can turn into, it can also become several mundane and trivial things such as a video game controller or a box of breath mints.
- Narcissist: He's pretty self-absorbed, to the point where his debut has him trying to justify a reason for a random street vendor to give him a free hot dog.
- Nightmare Fetishist: In the episode where he dates Eris, it's implied he's into it when she eats him (after she shapeshifts into a giant bug no less).
- One-Man Army: Generally has an easy time taking out hordes of supernatural monsters, though he has quite a bit more trouble dealing with Eris.
- Perma-Stubble: Pretty much a given that he'd always have a five-o'clock shadow, considering who he's based on.
- Pet the Dog: Even if he's pretty self-absorbed and oblivious about what's actually happening, he spends a lot of his first appearance on the show trying to keep two children 'safe' from what he (not without reason) assumes is a powerful, dangerous supernatural entity.
- Pre Ass Kicking One Liner: When he isn't belting out complicated and bizarre metaphors that don't apply to the situation, he's delivering really campy one-liners.
- Raised as the Opposite Gender: His parents spent a portion of his childhood bringing him up as "their little Rosie".
- Retcon: Underfist presents him as having fallen into depression following his breakup with Eris, gaining a beer gut, moving in with his mom, and generally being a much more pathetic mess than in the past. This goes against his multiple appearances after the breakup in the original series, where he was no different from how he normally was, as well as the fact that he was the one who initiated the breakup, not Eris.
- Soap Opera Rapid Aging Syndrome: A very rare occurrence of this in an adult character. He's stated to be 33 in Irwin Gets A Clue but is suddenly 48 in Underfist. What keeps this from being a Retcon is that he visibly looks fifteen years older in the latter, despite nobody else having aged at all.
- Solid Cartoon Facial Stubble: While having a few stray hairs thrown in, Hoss has his stubble predominantly shown by coloring the area between his nose and neck gray.
- Sour Supporter: Did not want to be part of Underfist, but President Mandy ordered him; by the end, he's warmed up to the idea.
- The Stoic: Most of the time, he's serious and unemotional.
- Swiss-Army Appendage: His cyborg hand (it was outright called his "Swiss Army Hand" in his video game profile). It can transform into a variety of things, ranging from a chainsaw-firing crossbow to a nose-shaped detector to a bouquet of flowers.
- Tank Goodness: His giant fist-and-arm-shaped tank which provides Fred Fredburger the idea for the Underfist team. It later gains a blue-and-yellow paint job but got wrecked by one of Bun-Bun's rotten gems.
- Testosterone Poisoning: An over-the-top parody of this. Everything he does exudes hyper-masculinity, even the most mundane, nonsensical, or pathetic tasks.
- Tragic Hero: His gruesome experiences with monsters has caused him to attempt to destroy every monster he sees, even harmless ones. This often gets him to become a Hero Antagonist.
- Took a Level in Badass: In the past. He used to be a loser like Irwin until he became the Hoss we know. Within the show itself, he's portrayed as being incompetent in his first episode and hypercompetent in all of his following ones.
- Took a Level in Dumbass: He was never particularly smart, but Underfist takes his lack of intelligence a step further.
- Top-Heavy Guy: His upper body becomes bigger and bigger while his legs become tinier. By Underfist he's obscenely beefy and supported by two tiny toothpick legs.
- Van Helsing Hate Crimes: He's a spectral exterminator, hunting monsters for a living. The problem being that not all of them are bad; Grim, for instance. He even took out a bunch of lawyers because he said they weren't human. Even after he retired from his profession, he still holds some prejudices towards monsters. In Underfist, he refuses to let the harmless Jeff and Fred Fredburger come with him to the Underworld because he doesn't work with monsters (or "one-eyed weirdos", in Skarr's case). He also hesitates in joining Underfist because of this. There's also his fights with Irwin, and the fact he tried to kill Irwin once he found out he was a vampire and a mummy.Hoss: Ivan is a mummy-vampire? That means you lied to me twice when you said you weren't a monster!
- The Worf Effect: Very present throughout Underfist, where he keeps getting his ass kicked in spite of all the previous times he's proven to be able to hold his own against any manner of supernatural creature.
- Would Hurt a Child: Had no problem kidnapping Billy, a young boy and potentially having him tortured.
- Wrong Genre Savvy: In his first appearance, trying to rescue Billy and Mandy from Grim would be heroic if he just wasn't ignoring their repeated entreaties that they're not in danger and Grim isn't even actually evil.
General Skarr
Voiced by: Armin Shimerman
Hector Con Carne's ex-paramilitary commander. He moved to Endsville after Con Carne's organization shut down, and became Billy's neighbor (much to his distress) and an avid gardener. Later joins the Underfist team. See Evil Con Carne for tropes relating to him on Evil Con Carne.
- Anti-Hero: In "Underfist", he is the Unscrupulous Hero, the nicest he has ever been. He does join the others in forming the titular team but is still not completely a good guy.
- Ax-Crazy: He tries to suppress this here, but if the chance calls, he shows this big time.
- Bald of Evil: As a parody of a paramilitary general, he has no hair on his head. And he doesn't mind it, he cared more about his bald chest.
- Berserk Button: In the name of all that is good, do not mess with his garden.
- Born Unlucky: Even ignoring his wimpiness and stupidity he tends to have such terrible luck that he can never establish himself as a genuine threat.
- Butt-Monkey: He suffers too many misfortunes to take seriously, yet he's too mean to really pity.
- Dub Name Change: He is named General Ernecio in the Latin American dub.
- Fake Defector: Pretends to betray the other heroes and side with Bun-Bun in Underfist.
- Expy: While he is obviously one to Herr Starr (read his Evil Con Carne page), he's one to Mr. Wilson, with how both deal with an obnoxious young boy who may or may not be pressing their buttons on purpose.
- Good Hair, Evil Hair: Gains a handlebar mustache and a goatee in Underfist.
- Hair-Trigger Temper: Well, he doesn’t have hair, but Billy very regularly manages to push his buttons and he reacts pretty hard.
- Large Ham: Well, he is voiced by Armin Shimerman.
- Meaningful Name: He has a scar on one of his eyes.
- Real Men Wear Pink: Is often seen gardening his front yard happily.
- Retired Monster: What he tries to be. While he doesn't regret any evil he did as Hector's commander, he still wishes to live a normal life in Endsville and fears relapsing into his violent ways. Alas, through various circumstances (sometimes by Billy), Skarr usually falls back into his villainy.
- Scars Are Forever: Skarr will be around fitting right into his name forever.
- Sissy Villain: A megalomaniac who knows his way around an attractive garden.
- The Starscream: Was an unstable and disloyal subordinate back when he worked for Hector Con Carne. He exploits the trope in Underfist by siding with Bun-Bun only to turn on him at the last minute.
- They Killed Kenny Again: Dies a few times, though he comes back the next time he shows up.
- Transplant: The only Evil Con Carne character to get elevated to recurring status here, and became a lead character in Underfist.
- Would Hurt a Child: Tries to kill Billy a lot.
Dick
Voiced by: Phil LaMarr
Irwin's dad and Tanya's son. He's friends with Harold, and it's revealed he's Dracula's son as well.
- Black and Nerdy: Like his son, he's a black geek.
- Boy Meets Ghoul: He married and had a child with an undead mummy.
- Dhampyr: As Dracula is his father, he's half-vampire, though unlike Irwin he never exhibits supernatural traits.
- Generation Xerox: Like his mother, he married a supernatural being. Worked out better for him, though.
- Hot Guy, Ugly Wife: Dick is an average-looking guy (though some would find him cute if one's into nerdy guys), while his wife, Judy, is a hideous mummified corpse. Admittedly in a flashback, she is shown to have been pretty good-looking and she has retained the curves but along with the rot.
- I Love the Dead: There's not really a way around it, the guy's wife is an ancient, barely sentient mummy. Lampshaded at the end of the reveal episode where Billy asks how they...got together and Dick simply reiterates that some questions don't need to be answered. Though this is before he found out he was half-vampire.
- Locked Out of the Loop: Doesn't know Dracula is his father and that as a result, he's half vampire until near the end of the show.
- Strong Family Resemblance: He looks like a taller, thinner version of his son.
- Translator Buddy: He interprets what his wife, Judy, says in "King Tooten Pooten".
- The Un-Reveal: Parodied when he talks about falling in love with a mummy and being in a long-term relationship with her: "Leaving a whole lot of questions that don't need to be answered."

Tanya
Voiced by: Phil LaMarr (old), Masasa Moyo (young adult)
Irwin's paternal grandmother, more commonly known as "Grandmama."
- Amazingly Embarrassing Parents: The short "Hate in an Elevator" had her become an amazingly embarrassing grandparent by telling humiliating stories about her grandson to Mandy while the three of them were stuck in an elevator. Once they're free, she continues to embarrass her grandson by telling the stories to the news crew that interviews them about their time stuck in the elevator.
- Badass Normal: She's only human, yet she went toe-to-toe against Goodbling and managed to tame her husband Dracula.
- Cool Old Lady: Unlike many of the adults on the show, she's more competent. You qualify as this if you're able to get Dracula, your husband to shut up and just eat their dinner.
- Curbstomp Battle: Delivered a one-sided beating to Principal Goodbling in the form of "yo-mama" jokes.
- Fourth-Date Marriage: With Dracula. A few steps less than fourth date actually. More like getting married after having just met.
- Hartman Hips: When she was younger, she had these
◊. - I Know Karate: Utters this when Van Helsing bumped into her, causing her to knock him out.
- I Was Quite the Looker: She was much prettier and attractive in her younger years, as shown here◊.
- Mama Bear: She's a loving grandmother towards her grandson, but if you dare hurt him in front of her…

- Only Known by Their Nickname: Her real name is Tanya, but it wasn't revealed until near the very end of the series.
- Third-Person Person: She occasionally addresses herself as "Grandmama".
Malaria
Voiced by: Jeannie Elias
A Goth woman who was briefly Grim's girlfriend.
- The Cameo: She has one in "The Incredible Shrinking Mandy" as one of Billy's attempts to cheer Grim up. But Grim seems to have gotten completely over her at this point since he doesn't even react.
- Death and the Maiden: She falls in love with Grim in the aptly named episode "Grim in Love". She shares his sadistic sense of humor and they both enjoy each other's company. By the end, he reveals to her that he is the real Grim Reaper and that all of his friends are actual monsters, leading her to run away in sheer terror.
- Early-Bird Cameo: She appears amongst the other side characters in the show's opening theme.
- Eerie Pale-Skinned Brunette: She has pale skin and black hair, fitting her goth aesthetic.
- Goth: Quite obviously. It's what attracts Grim to her in the first place.
- Impossible Hourglass Figure: She has a very prominent hourglass figure.
- Love at First Sight: With Grim.
- Meaningful Name: She's named after a disease.
- Satellite Love Interest: She doesn't really have much character depth outside of being a Goth and Grim's girlfriend, despite appearing in the show's intro sequence.
Ernest
Voiced by: Dwight Schultz
Skarr’s neighbour after moving to Endsville.
- Cloudcuckoolander: He’s fairly off. His first scene has him seemingly go mad and suddenly switch to affability.
- Cool Old Guy: Despite his eccentric personality, he seems like a pretty decent person to be around.
- Large Ham: Oh yes. His very first scene is screaming a bunch of warnings. Though it’s no surprise given that he’s voiced by Howling Mad Murdock himself, Dwight Schultz.
- Narrator All Along: In Skarred for Life, it’s implied Skarr himself is narrating the events of his first day in the neighborhood to a pizza guy. As it turns out, it’s actually Ernest and Skarr just returned home from vacation at the end of the episode.
- Nosy Neighbor: Shows signs of this in Herbicidal Maniac. It’s clear that he’s done this a few times.
Ms. Doolin

The old lady living in a house that Billy and Irwin are are afraid to go in.
- Berserk Button: Sexism. When she finds out what Billy and Irwin told Mandy, she happily agrees to help Mandy.

- Sheep in Sheep's Clothing: It appears at first she has malevolent intentions, but it turns out she’s a genuinely kind woman.
Nanny
Voiced by: Mitzi Mc Call
A famous television icon who's sent to rehabilitate Mandy.
