Voiced by: Vanessa Marshall

A nerdy boy and a close friend of Billy's. He has a crush on Mandy. Later revealed to have monstrous heritage and becomes a crucial member of Underfist.

  • Abhorrent Admirer: Mandy can't stand his crush on her. All of the occasions of her reciprocating his feelings 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.
  • A Day in the Limelight: Underfist, which was originally a Poorly Disguised Pilot.
  • Adorkable: He's a nerdy boy who desperately tries to look cool and he also comes off as sympathetic due to his relentless suffering.
  • Black and Nerdy: Though he's not smart at all (and he'll resort to cheating off of Mandy's answers on a test), he's black and has a geeky appearance, interests, behaviour and pastimes. More like black and dorky.
  • Black Best Friend: He's black and Billy's closest friend aside from Mandy.
  • Breakout Character: Gets steadily more appearances until becoming the main character of Underfist.
  • Butt-Monkey: Gets a lot of punishment along with Billy.
  • Characterization Marches On: Early episodes 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.
  • The Chew Toy: He is pretty much the Kenny variant of this show, as some episodes ended with him getting killed, yet he still comes back for more abuse.
  • Dark Is Not Evil: Played with, He's a mish-mash of various monsters, but is mostly a harmless and obnoxious nerd.
  • Dhampyr: At least, he is 1/4 Vampire (his paternal grandpa is Dracula).
  • Dogged Nice Guy: To Mandy. She never reciprocates his affections, no matter what he does.
  • 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.
  • Half-Human Hybrid: 1/2 Mummy, 1/4 Vampire, 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.
  • Red Eyes, Take Warning: His eyes glow red near the end in 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 Mandy's eyes glare at him. 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 her around 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).
  • 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.
  • 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.


Billy's father and Gladys' husband.

  • 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.
  • Autocannibalism: In "Super Zero", while picking his nose, he pulled his own brain out through his nose and proceeded to eat it.
  • Big Eater: Once ate a mucus covered rat alive because he was still hungry after two breakfasts.
  • Bumbling Dad: Like his son, he often doesn't care about anything and has a small IQ.
  • 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.
  • Closer to Earth: While he's dumber than Gladys, he's considerably more mentally stable than she is with what little mental functions he possesses and is quite relaxed around Grim.
  • Crouching Moron, Hidden Badass: A former Navy SEAL, according to "Dream Mutt".
  • 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!
  • Fat Idiot: He's obese and, while not as stupid as his son, very dumb. 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!
  • 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.
  • George Jetson Job Security: According to "Big Boogey Adventure", Harold has gotten fired from every single job he's had. Most recently, he lost his job at Freckle Burger for eating all the paper cups.
  • Happily Married: He and Gladys are clearly happy together.
  • 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.
  • 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: He's overall a decent guy, even if he's disgusting and rather stupid. While the show occasionally portrays him as a jerk, he's generally presented as a fairly sympathetic character.
  • Never Learned to Read: Admits to being illiterate in "Billy Idiot".
  • 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.
  • Odd Friendship: Is occasionally seen socializing with Grim.
  • Only Sane Man: In the early episodes, before the above mentioned Flanderization, he was this compared to his wife and son.
  • 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's an older, fatter Billy with a pompadour. A flashback in "Billy Idiot" shows that he also bears a resemblance to his own father.
  • Took a Level in Dumbass: Starts out as seeming reasonably intelligent, but eventually becomes much dumber.
  • 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 befriending the Grim Reaper. He and Grim are actually shown to be on fairly amicable terms most of the time.

Voiced by: Jennifer Hale

Billy's mother and Harold's wife.

  • Ambiguous Disorder: She's implied to be the source of Billy's psychopathic outbursts.
    Harold: Did someone forget to take their medicine today?
  • Anger Born of Worry: Her angry side was born from her worry of Grim, and she learned to not fear him, but destroy him.
  • Doting Parent: She is a caring but overprotective mother to Billy.
  • 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.
  • 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!
  • 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.
  • Super OCD: She goes nuts when things are out of order or untidy.
  • 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 Billy's dad, Harold, looks almost exactly like an older, fatter version of Billy.
  • Women Are Wiser: Subverted. While smarter than her husband, she's also mentally unstable and prone to fits of homicidal rage (which she passed to her son.)

    Mandy's Parents
Voiced by: Dee Bradley Baker (Phillip), Vanessa Marshall (Claire)

Mandy's parents. They are terrified of her.

  • Absolute Cleavage: A rare male example. Phillip's shirt is unbuttoned down to his naval.
  • 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 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 because they fear her, but it's implied she has some kind of supernatural control over them.
  • Satellite Character: They're Mandy's parents and... not much else.
  • Those Two Guys: They're mostly seen together.
  • Ugly Guy, Hot Wife: Not as extreme as Harold and Gladys. Phillip would be average looking guy if it wasn't for his big nose, while Claire is attractive.

    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.
  • 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.
  • 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.
  • Awesome Mc Coolname: His name is a pretty good indicator of his outrageous badassery.
  • Bad Butt: He's about as much of an over-the-top badass as a kids 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.
  • 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 Badass Baritone, 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 Badass Baritone.
    "I've been bitten by ghosts, haunted by mome raths and slapped by vampires... I think I've earned a free hotdog."
    "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 35, 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 to 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.
  • 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.
  • Guttural Growler: Speaks in a low growl.
  • 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 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.
  • 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".
  • Rated M for Manly: An over-the-top parody of this. Everything he does exudes hyper-masculinity, even the most mundane, nonsensical or pathetic tasks.
  • 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.
  • 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.
  • 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.
  • The Stoic: Most of the time, he's serious and unemotional.
  • 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.
  • 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 tooth pick 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 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.
  • 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.

  • Adorkable: Especially when he's gardening or trying to be a good neighbor.
  • 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.
  • Badass Beard: In "Underfist", he has a goatee.
  • 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.
  • Good Hair, Evil Hair: Gains a handlebar moustache and a goatee in Underfist.
  • Growling Gut: As of "Anger Mismanagement".
  • Meaningful Name: He has a scar on one of his eyes.
  • The Neidermeyer/The Starscream: Was an unstable and disloyal subordinate back when he worked for Hector Con Carne. He exploited the trope in Underfist by siding with Bun-Bun only to turn on him at the last minute.
  • Real Men Wear Pink: Is often seen gardening his front yard happily.
  • 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.
  • Transplant: The only Evil Con Carne character to get elevated to recurring status here.


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.

  • Adorkable: Surprisingly showed some traits of this in "Wrath of the Spider-Queen" and "Underfist", like acting giddy after defeating spiders with her bare hands or randomly breaking out into an air guitar solo of a song she just sang.
  • 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.
  • Disproportionate Retribution: When Mindy first moved in 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 became her obnoxious rival ever since.
  • 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.
  • Heel–Face Turn: At the end of "Underfist", she turns against Bun Bun and decides to stop being evil.
  • 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!
  • 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.
  • 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.


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.
  • Dub Name Change: His name is changed to Pecas in the Latin American dub.
  • 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 what Pud'n is doing outside so late at night, only for Pud'n to show that he was raised by wolves, and they live outside. The wolves are watching television and one 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.

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": Her real name is never given. She's named by her relation to Billy's family. She's Billy's aunt and Harold's sister.
  • Gag Nose: Her nose is as big as Billy's and Harold's noses.
  • Happily Married: She ends up marrying Nergal and having a son with him.
  • Maiden Aunt: Before marrying Nergal. Gladys explicitly calls her a spinster when explaining to a curious Billy as to why she "ain't got nobody".

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.
  • Black Best Friend: He is black and Harold's best friend, much like the relationship between their own sons.
  • Boy Meets Ghoul: He married and had a child with an undead mummy.
  • Dhampyr: As Dracula is his father, he's half-vampire.
  • 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.
  • 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."
  • Verbal Tic: Tends to end his sentences with "Dude!".

Irwin's 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.
  • 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.
  • 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.
  • Third-Person Person: She occasionally addresses herself as "Grandmama".

     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 kidnappped 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.
  • 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.
  • 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.
  • 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.
  • No Celebrities Were Harmed: He sounds remarkably like Paul Lynde.
  • Pretty Fly for a White Guy: Becomes a Gangsta Rap-based villain of some sorts 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.
