Western Animation: The Grim Adventures of Billy & Mandy
aka: Grim Adventures Of Billy And Mandy
The Grim Reaper
has come for a soul — specifically, a hamster in his dying days — but he's stopped from taking the hamster to the afterlife by two children: the blissfully idiotic Billy
(the hamster's owner) and the cynical, amoral Mandy
(Billy's best friend). The pair challenge "Grim" to a limbo contest to save the hamster
; when Grim loses, he becomes Billy and Mandy's newest friend — and by "friend", we mean that he's contractually bound to be the kids' friend and cater to their every whim. Grim begrudgingly serves as something of an underworld version of Mary Poppins, thanklessly placating Billy's demands for cheap entertainment and Mandy's schemes for self-profit with his magical scythe while desperately trying to find a way to be rid of the duo for good. Thus go The Grim Adventures of Billy and Mandy
Rounding out the show's cast are Irwin, Billy's best friend and the Token Minority
(who also has a massive crush on Mandy); Sperg The Bully
; Mindy the Alpha Bitch
; Hoss Delgado
, a supernatural bounty hunter with more brawn than brains; Eris, the goddess of chaos and discord; General Skarr (formerly seen in Evil Con Carne
), who now wants to garden instead of conquering the world; and Nergal, the Sumerian Death God who lives in Earth's molten core and just wants to be friends with everyone, really.
This show was actually the winner of a contest held by Cartoon Network
to determine what cartoon would be their next new show
. On an interesting note, Billy and Mandy
ended up lasting longer than most of the shows that CN greenlit without fan input; Codename: Kids Next Door
, the winner of the contest the following year, did likewise. (Think about this: those two shows, voted to greenlight status by the viewers, ended up lasting at least two more seasons than any other show CN greenlit afterward). Billy and Mandy
was originally a much darker Three Shorts
show that included another cartoon, Evil Con Carne
(and known then as Grim & Evil
), but became the more comedic (but still pretty dark) Grim Adventures of Billy and Mandy
when Con Carne
was dropped after the first season in an unsuccessful Spin-Off
The show lasted seven seasons (2001-2008) with two movies, a couple of specials — including a crossover with Codename: Kids Next Door
— and a spin-off attempt called Underfist
This show provides examples of:
- Accidental Misnaming: "It's Good-VIIIIIIIBES! "
- Alpha Bitch: Mindy.
- Alternate Universe: It shares the same universe as Evil Con Carne, a universe where Abraham Lincoln is still President, and the League of Nations still exists. Its also hinted that it shares the same universe as Codename: Kids Next Door and Ed, Edd n Eddy, per the crossover. In one episode, due to the collapse of time and space, the universe is rebooted and the characters are reincarnated as the cast of The Powerpuff Girls.
- ...Which might also be part of the same universe.
- Animesque: Billy's favorite show, The X-Treme Adventures of Brandon and Mallory. It features ninja fights, high-speed chase scenes, giant robots and wailing guitars and stars two kids with the Grim Reaper.
- Also used for a quick one-off gag when Grim was trying to use his magic to fix Billy's eyesight, Grim and Mandy appear in his eyes in an anime style. Somehow, this includes speaking Japanese.
- Arson, Murder, and Jaywalking: Billy's dad's lucky pants are immune to lasers, supernatural forces, and mustard.
- Art Evolution: Lampshaded in one episode, where the original episode is played to end the dispute in the character's conflicting origin stories. Grim remarks, "That doesn't even look like us!"
- Likewise, in one episode Fred Fredburger (yes!) lampshades Mandy's lack of an apparent nose.
- Art Shift: An episode ended with Billy needing Grim to fix his eyes, and with each attempt, he sees the world rendered in a different animation style.
- Assimilation Backfire: Happened to a brain-eating alien, when it was dumb enough to consume Mandy's brain.
- An Ass-Kicking Christmas: Billy and Mandy Save Christmas.
- Attack Pattern Alpha
- Attractive Bent-Gender: Averted. When Sperg the bully gets ahold of the wish-granting skull, the only thing on his mind is being able to go into the girl's restroom to rob them all of their money. Cue him turning into a girl so he can go in there, but the girls ridicule girl-Sperg for being such an ugly girl that he/she runs out crying. "Girls are so mean!"
- Autocannibalism: Billy is turned into chocolate, and finds himself so irresistible that he eventually eats himself down to just his head. Apparently, he's not the first to do so.
- Awesome McCoolname: Billy's Martian pet, "Admiral Wolverine Lightningbolt".
- Bad Santa: Voiced by Gilbert Gottfried in a Christmas episode/movie. Actually Santa isn't really bad, he is occasionally turned into a vampire by Mrs. Claus, who was a vampire before they married. That's happened quite a few times before.
- Balloon Belly: Billy sometimes does this when he binge-eats.
- Bat Family Crossover: In the episode Company Halt, Skarr gets a visit from his exco-workers Hector Con Carne and Major Ghastly, as they reinstate the Evil Con Carne criminal organization, develop a new diabolical weapon* and using it to terrorize the citizens of Endsville. Needless to say, Grim, Billy and Mandy go out and stop them.
- Beware the Silly Ones: Billy is often the dumbest one on the show, but he has been shown to have bouts of psychotic rage that scares even Mandy.
- Bigger on the Inside: Grim's trunk. Billy points this out by name in one episode when he, Mandy, and Irwin climb inside it.
- Bilingual Bonus:
- The Dwarven battle cry is "laven sus manos," Spanish for, "wash your hands."
- One of Hoss Delgado's Pre Ass Kicking One Liners is "Piso mojado, dirtbag!", Spanish for "Wet floor, dirtbag!"
- Black and Nerdy: Irwin.
- Black Comedy: The whole genre in the series. One of few kids shows with it, combined with Grossout Show.
- Blondes Are Evil: Mandy. Eris also counts.
- Breaking the Fourth Wall: This show holds the record as the Cartoon Network show with the most fourth wall jokes. Listing all of the examples would take up a lot of space on this page.
- Breakup Breakout: After breaking off from Evil Con Carne, it became the more successful of the two shows.
- Broke the Rating Scale: Billy managed to score himself a NEGATIVE 5 on an IQ test, being outperformed by a shovel and a pair of candy bracelets.
- Broken Record: "DESTROY US ALL! DESTROY US ALL! DESTROY US ALL! DESTROY US ALL! DESTROY US ALL!note DESTROY US ALL!" Also counts as a Madness Mantra, a Memetic Mutation, and an Ear Worm.
- Fred Fredburger, Fred Fredburger, Fred Fredburger, Fred Fredburger, Fred Fredburger, Fred Fredburger, Fred Fredburger, Fred Fredburger, yes!
- Butt Monkey: Grim and Billy, naturally, but "Super Zero" had this adorable alien creature, who wanted to be Billy's friend, kept taking Billy's constant, near-lethal abuse.
- Nergal doesn't start out this way, but as of "Loser from the Earth's Core," this becomes one of his defining character traits - including a cameo during "The Incredible Shrinking Mandy" solely for the purpose of having him be crushed by random falling things. Even lampshaded slightly in "Underfist," when his family knows something bad is coming because he brought up how well things are going for him...
- Call to Agriculture: Skarr, the Canon Immigrant from Evil Con Carne just wants to be left alone and do his gardening.
- Characterization Marches On: In the first episode she appeared in, Eris acted like a typical giddy blond teenage valley girl. Afterwards though she acted more regal and queenly with a British accent. Also a Shout-Out to Madonna.
- By her next appearance, her personality change is lampshaded and Hand Waved away by her going through "a Valley girl stage" as is Grim's crush on her during that episode/stage.
- Mandy used to smile on occasion—though, usually after doing something horrible to the human race. In a much later episode, Mandy smiling tears apart the fabric of space and time.
- Mandy started out as an apathetic Anti-Hero before becoming a sociopath who only saves the world so it will be free for her later, takes pride in being utterly evil, and suffers physical strain to say "please".
- Mindy is pretty much a completely different character in her first few appearances.
- Grim wanted to kill the kids at first, but later decided they're his only living friends.
- Chekhov's Gun: From "Meet the Reaper", "Kiss kiss."note
- Christmas Cake: Parodied with the host of Grim's favorite late-night show, Atrocia, whose show was cancelled the moment she turned 30.
"The network said no one wants to see a worn-out old bag like me on TV anymore."
- City of Adventure: Endsville.
- Cloud Cuckoo Lander: Billy. Also, Fred Fredburger.
- Comic Trio: Mandy is the schemer, Billy is the follower, and Grim is the complainer.
- Couch Gag: A message to the viewers, usually from Mandy, at the end of the theme song.
- Cranium Chase: Grim is a constant victim of this.
- Crapsack World: Though if the Codename: Kids Next Door crossover is to be believed, it's confined to Endsville, and the rest of the world is just fine.
- Creator Cameo: Maxwell Atoms appears in one episode, just long enough to poof out of existence after Billy breaks the hourglass representing his lifespan.
- Crossover: Sort of. Numbuh 3 appeared four times in Big Boogey Adventure.
- In "Modern Primitives", Billy finds Fred Flintstone frozen in his backyard.
- Early on in "Here Thar Be Dwarves", Billy's picnic is interrupted by Yogi Bear and Boo-Boo.
- The Codename: Kids Next Door crossover episode, which was not only a crossover of KND and this show, but of every one of CN's original shows (that weren't created after its release). At least one character from each show appears in the episode, even one from Squirrel Boy.
- Mandy even appears in Foster's Home for Imaginary Friends. She was there as part of a montage of people returning imaginary friends to Foster's. The one that she was returning was deemed "too happy".
- The Great Grape Ape appeared as a giant monster on "Giant Billy and Mandy All Out Attack"
- Cut Apart: In "Secret Snake Club".
- Dawn Attack: Mandy puts on an army helmet and says "We attack at dawn" in the show intro.
- A Day in the Limelight: The finale movie starring the side characters, Underfist. Billy, Mandy, and Grim only made some cameos.
- Dead All Along: An odd example. In the episode "Who Killed Who", it's implied that the old lady in the haunted house really was a ghost.
- Deadpan Snarker: Mandy, definitely. Grim has his moments, too.
- Dean Bitterman: Dean Toadblatt, specifically against Weaselthorpe House, and especially against Nigel Planter. Extra points for being voiced by the original Dean, John Vernon, in a parody of his role in Animal House.
- Death's Hourglass: Parodied when Grim, Billy, and Mandy entered a sanctuary filled with the hourglasses of every human being on earth. Not only does Billy flip his and Mandy's hourglass, resulting in their lives instead moving backwards until the point where they don't exist anymore, but he even flipped Grim's hourglass too (odd considering Grim's hourglass was enormous). They also break at least one, causing that person (the show's creator) to blip out of existence.
Irwin: "Whose hourglass was that?"
Billy: "Eh, prolly no one important."
- Derailed Fairy Tale: "Nursery Crimes" starts the kids in the story of Hansel and Gretel, but they wander off and encounter characters from other fairy tales such as Pinocchio, who wants to Become a Real Boy by eating the flesh of a real boy.
- Detonation Moon: In the alien invasion episode.
- Deus ex Machina: Grim, but more specifically, his scythe which can do anything.
- Perhaps the biggest example in from the KND crossover, with the Bone of Barnacles, which was supposed to be a torture device used on Numbuh 1 to get information out of him, but was later used to give Numbuh 1 a giant mecha sized suit of Bone Armor to fight the Delightful Reaper.
- Devil in Plain Sight: Guess...
- Dhampyr: Irwin, although he's more 1/4 vampire, 1/2 mummy, and 22/7 nerd.
- Genius Bonus: 22/7 is the fractional approximation for pi.
- The Halloween episode where he was bitten by a werewolf.
- Did You Just Punch Out Cthulhu?: Seen in "The Prank Call of Cthulhu".
- The Ditz: Billy, and how!
- Does This Remind You of Anything?: This exchange in "Big Boogey Adventure" between Boogey and Creeper, after Boogey fails to scare Creeper.
Boogey: Aw, would it kill you to fake it just once?
Creeper: (sarcastically) It'll make the time when you really scare me all the more special.
- Don't Fear the Reaper: Grim tries his darndest to be scary, but at his most badass, the guy's still an incompetent wuss. The way he became the Grim Reaper involved a pretty awesome display as revenge for ruining his friendship with his best friend. So he's somewhat weak-willed..Unless you manage to REALLY piss him off.
- Double Entendre: Billy once visited Uncle Chokey the chicken juggler.
- Dumbass Has a Point: In "Billy and Mandy vs. The Martians":
- Also in "The Incredible Shrinking Mandy" After Billy makes Mandy a giant, and she wants him to turn her back to normal
Grim: Billy! Just Change Mandy back!
Billy: NO! You always let Mandy have her way! I don't want to encourage her.
Grim: Well...you were the one who encouraged her with the whole cannibalism thing.
- Early Installment Weirdness: A Running Gag in later seasons is that Mandy never smiles... except she has in early episodes as seen under Perpetual Frowner. Also, the Grim & Evil episodes were much darker in tone.
- Easter Egg: There was once an actual site online mirroring the Secret Snake Club's 1-page shrine to their god Shnissugah (which consisted of an animation of the deity in question slithering back and forth, "dancing" if clicked on, a message saying they would "pwn the cool kids," and some fake ads).
- Eldritch Abomination: Nergal Jr's true form is apparently horrific. Cthulhu's also showed up, and Yog Sothoth almost did. Also, Mandy. (At least to her antagonists, and quite literally when she assumes an immortal slug form in the future, allowing her to conquer Earth.)
- The ending of "Scary Poppins" where she is able to MIND CONTROL EVERY SINGLE CHARACTER FROM THE SHOW to scare the nanny away shows that Mandy is implied to be one.
- Elemental Plane: One of several D&D references involved Grim trying to take Billy and Mandy to the elemental plane of fire.
- Elves Versus Dwarves: A whole episode devoted to the subject.
- Enfant Terrible: Mandy is the patron deity.
- Even Evil Has Standards: Mandy may support any and every legitimate attempt at revenge, dreams of ruling the world as a dystopian dictator, and doesn't flinch at any of the hellish Eldritch Abominations we see throughout the show. But she does NOT condone cheating.
- Evil Is Not a Toy + Be Careful What You Wish For: Thromnambular (voiced by Dwight Schultz, no less)
- Evil Versus Evil
- Expy: The eponymous characters are simply human (and gender-bended, in Mandy's case) forms of Ren and Stimpy. They even copied the nose.
- Extreme Omnivore: Billy.
- Eye Scream: In the episode "Complete and Utter Chaos", Billy is poked in the eye by the Apple of Discord (which had sprouted mechanical spider legs) in his sleep.
- Face Your Fears: In order to claim possession of Horror's Hand (which makes people see their worst fears come to life), Billy, Mandy, and Irwin must face their fears to overcome it.
- Family-Unfriendly Death: All too common in the early episodes.
- Fan Fic: Grim Tales from Down Below derived from this.
- Fantastic Racism: Hoss Delgado's prejudice against monsters.
- Five-Man Band: Underfist.
- Flanderization: Mandy, believe it or not. Earlier in the show, she was very witty and snarky, but by no means intimidating enough to order her own parents (or anyone else other than Grim, Billy, and Irwin) around. She also had a rare smirk or two in the early episodes before becoming a complete Perpetual Frowner whose smile could bring about The End of the World as We Know It. She was probably more of an Anti-Hero in some of those earlier episodes rather than the more consistent Nominal Hero later on.
- Flat Earth Atheist: Mandy.
- Fluffy the Terrible: Mandy.
- Forgotten Fallen Friend: In Nergal Jr.'s origin episode, he paralyzes a boy who was disgusted by his appearance and shapeshifts into his form, doing the same to all other children he meets who refuse to be his friend (as an homage to John Carpenter's The Thing (1982)). In future episodes, this boy's form is Nergal Jr.'s "default". The other children were rescued by Billy and Mandy, but Nergal Jr.'s initial victim is never mentioned or seen again... and this episode takes place in bitterly cold weather.
- The Fourth Wall Will Not Protect You: "And you. You will be my closest, most bestest friend of all!"
- Fratbro: In "Attack of the Clowns", while Mandy and Grim are trying to help Billy conquer his fear of clowns, Billy goes to his happy place in his mind where he encounter his imaginary "Inner Frat Boy" who helps Billy conquer his fear.
- The Freelance Shame Squad: Grim meets up with his old schoolmate, The Boogeyman, and is not happy about it. When asked why, we flashback to their school days, where Boogey gave Grim a giant wedgie in front of the whole school. Right before they all laugh at him, one monster says "Let's all point and laugh at his humiliation!"
- Future Badass: In the Dune parody in which Future Mandy rules the world, Irwin (or a descendant) is the huge, muscular leader of La Résistance.
- Gasshole: Billy and Mandy (somewhat).
- Getting Crap Past the Radar: A whole page.
- Giant Spider: Jeff, is a partial subversion - he's a giant spider, but he's extremely friendly, kind, and only wants his father (Billy) to love him. Billy's arachnophobia makes things very difficult...
- Girl with Psycho Weapon: When Billy's mom tells you that dinner is ready, you better get your butt to the table. * revs up the chainsaw*
- The Grim Reaper: Obviously.
- Gross-Up Close-Up
- Grossout Show: Played for Laughs.
- Hair-Raising Hare: In "Wishbones" Pud'n wishes for a pet rabbit. The rabbit repeatedly attempts to kill him, no matter how badly injured it becomes.
- Heroic BSOD: Happens a few times. Mandy nearly has one when, in the Big Boogie Adventure, Billy is dragged underwater by the Kraken and doesn't seem to surface. She instantly comes to her senses when Billy finally resurfaces.
- Humanoid Abomination: Nergal Jr and possibly Nergal.
- Oh, and if you've seen "Scary Poppins", Mandy is seen to be one as well, controlling everybody in Endsville.
- Humiliation Conga: Boogie gets this to absolutely insane levels after Grim takes Horror's hand from him. A rock falls off the ceiling and lands on him, the ground he's standing on breaks and said rock falls on him again, the ground breaks again and the rock follows, he gets thrown into the ceiling by the giant squid from earlier in the episode, again, along with the rock, he lands (but not before getting attacked by a swarm of bats on the way down) and gets crushed by the rock, which breaks, only for a bus to come out of nowhere and send him flying into his ship, which tilts and sends him hurtling into a cannon, which fires him through his ship and into a wall, sinking it.
- Hypercompetent Sidekick: Grim.
- Hypocritical Humor: During the Underfist special.
Wait a minute, I'm not a monster. Hoss Delgado:
No, but I don't trust one-eyed weirdoes either.
- I'm a Humanitarian: The series' version of Pinocchio believes that the only way he can become a real boy is if he eats the flesh of a real boy. One episode (Which Came First) has Sperg eat Pud'n's arms and legs after they get stranded in the desert together, though that becomes part of the show's Negative Continuity, while another episode (Tastes Like Chicken) is all about Billy jumping to the conclusion that Mandy is a cannibal who's eaten his friends and family and plans to eat him next, which ends with a played-for-laughs implication that she actually has eaten Irwin.
- Implausible Deniability: In "Runaway Pants", Billy attempts to run down the street only to become exhausted taking a short leap forward. When Mandy tells him that he's out of shape, he's quick to deny it.
- I Ate WHAT?: Grim's cookies. For those who don't know, Aunt Kali's secret ingredients are dung beetles, nightcrawlers, and mashed crickets.
- I Fell for Hours: During Mandy's interpretation of Humpty Dumpty in "Nursery Crimes" with Billy as the main character.
- I Got a Rock: In "Grim or Gregory," Billy gets a rock. And promptly eats it.
- I Taste Delicious: Provides the page image. In one episode, Billy is changed into pure chocolate, and can't stop eating himself.
- Informed Judaism: Billy in the Christmas Episode.
- Interspecies Romance: Nergal and Aunt Sis's marriage is never presented as anything other than a mutually loving relationship. (But they did have a rather Creepy Child together.)
- Jackass Genie: The wishing skull, Thromnambular.
- Jerkass: Mandy.
- Also a Jerk Sue on many occasions.
- The Jerk Sue ness often tends to piss off a few people. This fan art sums up the complaints wonderfully.
- Strangely, this makes her beast transformation in the "Sickly Sweet" episode oddly appropriate. Just listen to the animal sounds she makes whenever she isn't spazzing out. Sound familiar?
- Jerk with a Heart of Jerk / Jerk with a Heart of Gold: Sperg. He constantly shifts between the two, even in the first episode he appeared in. He kicks the crud out of Billy, gets scared off by Mandy, gets cheered up by Billy, and wedgies Billy before the iris in. All in one episode. In the episode where he and the rest of the cast fight off aliens, 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.
- Kick Me Prank: When Grim narrates about Jack, you see Jack using this prank on various people in the animated montage.
- Kill 'em All: The episode "Wishbones". 9 characters have their wishes granted. Not many of them survive. Though retconned when Grim wishes Billy and Mandy never found the skull, undoing the wishes.
- Lampshade Hanging: In one episode, people are sucked through telephones and into an alternate dimension, leaving behind their shoes. Mandy asks why the shoes were left behind and Grim comments, "Of course they got left behind, shoes can't fit through a telephone, they're way too big."
Mandy: What are you doing?
Billy: I'm singing! There's always singing in animated movies!
- Half of the show is one big lampshade hung up like a giant pinata.
- At the end of Super Zero, Billy asks Grim if he could be changed back from a superhero to a normal boy. Grim, frustrated, yells:
Grim: THERE'S NOTHING NORMAL AROUND HERE!!!!!
- Lightning Can Do Anything
- Little Miss Snarker: Mandy could be the trope namer.
- Limited Wardrobe
- Mid-Battle Tea Break: A subversion. When Grim, Billy, Mandy, and Irwin are racing against Boogie and his crew for possession of Horror's Hand, part of the race itself is a stop for lunch at noon.
- Midlife Crisis Car: Discussed.
- Mistaken for Pedophile: In "Duck!" Grim is seen trying to show children he can't be the one making fart noises by showing them his skeleton body and his lack of organs while shouting "Look at my body!". He is arrested shortly afterward.
- Mr. Seahorse: Jeff.
- Mrs. Claus: Who is a vampire.
- Multi-Character Title (if you count "Grim" as being one of three character names in the title)
- Multiple-Choice Past: The origins of Grim and his profession vary from time to time, should the plot of the episode call for it.
- Musical Episode: The "evil meteor from outer space" short was a Shout-Out to Little Shop of Horrors, with original music by Voltaire.
- My Little Phony: Grim's favorite show "My Troubled Pony", combining colorful ponies with an over-the-top Soap Opera. Unfortunately for him, it was Cut Short.
- Name and Name (Grim and Evil, Billy and Mandy)
- Negative Continuity: Although it tends to recall certain events of various episodes.
- Never Say "Die": Obviously averted, what with death itself being a main character and all, and an episode titled "Who Killed Who?".
- Also we have a tidbit where Grim says "Billy, what were you trying to do? Scare me to me?"
- Never Trust a Hair Tonic: Billy tries some hair tonic and ends up growing hair all over his body looking like a sasquatch. It turns out that all he has to do to get rid of it is wash it off.
- No Celebrities Were Harmed: Principal Goodvibes is most likely an Expy of Paul Lynde.
- No Fourth Wall: And how!
- Nonindicative Name: "The Incredible Shrinking Mandy" is actually about Billy attempting to shrink Mandy but accidentally making her giant.
- "Billy's Growth Spurt" even has a Nonindicative Title Slide depicting Billy as a middle-aged hick, when in fact the episode revolved around a growth on his back that eventually detached and turned into a miniature version of Billy (affectionately named "Yawb-yawb" by Billy himself for the sound it makes).
- Non Sequitur Thud: Billy's first appearance in Underfist includes this.
- Noodle Incident: Several of the people stated by Boogie to have stolen Grim's scythe (including a girl scout troop, the Sleestaks from Land of the Lost, and a turkey salad sandwich) were not shown stealing it in the show, leading one to speculate what may have happened during these incidents.
- Not Even Bothering with an Excuse: Combined with Rule of Three to make a minor Running Gag in one of the Nigel Planter-centric episodes; whenever Nigel starts singing and playing with a puppet, two characters make up excuses to leave, while the third doesn't bother justifying themselves.
Grim: I, uh... I have to meet somebody.
Billy: I left the oven on.
Mandy: You're weird.
- Nothing Exciting Ever Happens Here: Endsville. Justified in that a town where Death resides is bound to be a weirdness magnet.
- Not This One, That One: Billy and Pud'n entered a pie eating contest and Billy ate all the pies he saw at a table. However, those were Pud'n's pies. Pud'n was declared the winner.
- The Nudifier: General Skarr's "Atomic Hot Pants Raygun". Well, it doesn't cause his clothes to disappear, just change, but, still.
- Off Model: Nergal and Nergal Juniors' teeth sometimes switch from jagged to flat and back again when they're talking.
- Oh, Crap: Jack O'Lantern displays this expression when the knight who killed him (really Irwin in a knight costume) has returned to finish the job.
- Opposite Day: A short in the first episode, as reckoned once the Evil Con Carne shorts were removed.
- Overly Long Gag: DESTROY US ALL! DESTROY US ALL! DESTROY US ALL! DESTROY US ALL! DESTROY US ALL! DESTROY US ALL! DESTROY US ALL! DESTROY US ALL! DESTROY US ALL! DESTROY US ALL! DESTROY US ALL! DESTROY US ALL! DESTROY US ALL! DESTROY US ALL! DESTROY US ALL! DESTROY US ALL! DESTROY US ALL! DESTROY US ALL! DESTROY US ALL! DESTROY US ALL! DESTROY US ALL! DESTROY US ALL! DESTROY US ALL! DESTROY US ALL! DESTROY US ALL! DESTROY US ALL! DESTROY US ALL! DESTROY US ALL! DESTROY US ALL! DESTROY US ALL! DESTROY US ALL! DESTROY US ALL!...
- I'll take the chicken.
- DESTROY US ALL! DESTROY US ALL! DESTROY US ALL! DESTROY US ALL! DESTROY US ALL! DESTROY US ALL! DESTROY US ALL! DESTROY US ALL! DESTROY US ALL! DESTROY US ALL! DESTROY US ALL! DESTROY US ALL! DESTROY US ALL! DESTROY US ALL! DESTROY US ALL! DESTROY US ALL! DESTROY US ALL! DESTROY US ALL! DESTROY US ALL! DESTROY US ALL! DESTROY US ALL! DESTROY US ALL! DESTROY US ALL! DESTROY US ALL! DESTROY US ALL! DESTROY US ALL! DESTROY US ALL! DESTROY US ALL!
- Also, the flashback when Billy wants to go on a picnic.
- Overwhelming Exception: Despite Mandy's apathy and cold personality towards anyone she encounters it has been implied multiple times that Mandy actually cares for Billy and he is the only one she respects the most (unlike Grim who gets abuse on a regular basis by slave labour while billy would relax with Mandy) A notable example would be in Billy & Mandy's Big Boogey Adventure she was in denial and was teary eyed when Billy supposedly died however she was pleasantly surprised that he had survived but regretted worrying about him because as she said "billy's always fine".
- Mandy has commented several times that she hates Billy, and she would rather not have him in her life. But, in the Dune parody, she has a Billy Clone and a lot of spares made after the original died. If she truly hated him she wouldn't have made clone of him.
- Perpetual Frowner: Mandy.
- If she does smile, the very fabric of reality is pulled apart. A Crowning Moment of Funny ensues.
- "YOU FOOLS! YOU'VE DISRUPTED THE NATURAL ORDER!"
- Also a result of Flanderization since in the Grim & Evil shorts and some episodes of earlier seasons did show her smiling more. Not a whole lot more, but not to "must never smile" extremes.
- Bit of Fridge Logic perhaps, but in previous instances of Mandy smiling, she had a reason. In the pageant, her smiling without cause broke the rules.
- Whenever she smiles and nothing bad happens, something bad's already happened, and she was merely pleased with the — often unsettling — results.
- Physical God: Eris is one of these.
- Playing Pictionary: Dracula's Pictionary drawing of Abraham Lincoln is mistaken for successively more absurd things.
- Popular Is Dumb: Mindy, definitely.
- Portal Pool: One episode featured Grim's sythe reflecting sun light on to Billy's pool. Naturally, everyone jumps in.
- Potty Emergency: The episode "Terror of the Black Knight" is all about this. Billy wants a badass knight costume just like Irwin, so Grim gives him one, but unfortunately, Billy drank too much punch that he has to use the bathroom, and he can't get the knight armor off unless he wins a challenge with someone. He then wins a breakdancing contest against Mandy, but as soon as he gets his armor off, he doesn't have to use the bathroom anymore. You can also hear splashing sounds during the breakdance scene.
Mandy: So, aren't you gonna rush over to the boys' room?
Billy: You know the funny thing? I don't need to go anymore.
[Billy walks off]
- In the Christmas special, Billy mistakes the Mall Santa line for the line to the bathroom. "I feel like my bladder's gonna explode!"
- Also happens in the episode "Tricycle of Terror", after Billy drinks too much lemonade.
- Power Trio: Mandy (evil), Billy (stupid), Grim (hapless)
- Pragmatic Villainy: In the crossover, the Grim Adventures of the Kids Next Door, Mandy and the Delightful Reaper get into a Giant Mecha style fight. Once Grim and Numbuh One get on the scene, she allows herself to be assimilated so she can join the winning team, and also seems to totally take over the Delightful Reaper's Hive Mind in the process.
- Production Throwback: The film grain effect during the title sequence hides this, but the gravestones are inscribed with the names of three fellow series (Evil Con Carne, Time Squad, and Whatever Happened to... Robot Jones?), all of which were cancelled during the production the show's first solo season.
- Properly Paranoid: Gladys, Billy's mom. She has every right to be paranoid of Billy hanging out with the Grim reaper, considering he reaps souls and all.
- Pun: During the Christmas Episode, Grim and Mandy are busting into the lair of a vampire, coming to a locked door, which does nothing to deter Grim. Mandy asks how they expect to get through, to which he replies "A skeleton key!" He is then pelted with a snowball.
- In "The Firebird Sweet", Mandy asks what type of cereal box comes with a phoenix. Grim looks at the box and says, "Well, this cereal came from Arizona." In other words, Phoenix, Arizona. (except we see it came from "Eris-zona" - a place owned by the Goddess of Chaos, Eris.
- Punctuated! For! Emphasis!:
- In "My Fair Mandy": "IMPORTANT! COMMERCIAL! MESSSAAAGGGEEE!"
- Put on a Bus: Billy's Mom goes away to live with her sister in the first episode of the main series but comes back in the same season. (Which, for strange scheduling reasons, was 11 months later.)
- Raised by Wolves: Pud'n was raised by wolves. Funnily, said wolves are seen watching TV in his backyard after he reveals this.
- According to Mandy's parents, a band of wolves stole her away shortly after she was born to invoke this trope. They're both still unsure if getting her back was really for the best.
- Relax-o-Vision: In "Here There Be Dwarves", a Drill Sergeant (voiced by R. Lee Ermey, no less) pops up to explain they'll be showing a cute koala instead of the overly-violent battle between the dwarves and the elves.
- Reverse Cerebus Syndrome: The early episodes are a lot darker and morbid in tone. After a few episodes though the series hit it's stride and evolved into the wacky, nonsensical show it's known as.
- Retraux: One episode had the trio wind up in a world made to homage the black and white cartoons from The Golden Age of Animation. Too bad Mandy puts a stop to it, since she despises retro cartoons.
- Ridiculously Cute Critter: Milkshakes, Billy's pink cat.
- Right on Queue: The episode "The House Of Tomorrow" has a seemingly short line for a rollercoaster, but it turns out that's the line you have to wait on to get on line for the rollercoaster.
- And apparently, somebody died on the line and a baby was born on it.
- Road Sign Reversal
Dean Toadblatt: Hey, jerkwad, you’re going the wrong way! The Enchanted Meadow is in that spooky cave, and the deadly Manticore is in that happy meadow! Can’t you read?
- Robot Me: Mandroid and Billybot in the first movie.
- RPG Episode: Grim's idea of breaking Billy and Irwin's video game addiction, didn't work as intended.
- Sanity Slippage: Happens quite a few times, but one of the most notable is when Mindy loses her cheerleader position. This stirs up the B plot of the respective episode, making Mindy attempt to hinder, incapacitate, and even kill Mandy to get her position back.
- Sassy Black Woman: Irwin's Grandmama, Tanya.
- Saving Christmas: "Billy & Mandy Save Christmas"
- Scare Dare: An abandoned house. It's just some old lady living alone. Well, OK, she is also a ghost.
- School Clubs Are Serious Business: There was an episode where the students joined school clubs. Mandy joined the Secret Snake Club, who believes in a snake-god that will eat all of the cool kids. Billy joined the Secret Service club, and discovers the knitting club is being used as a criminal front.
- The Scottish Trope (saying "Lord Moldybutt")
- Hilariously enough, not even Lord Moldybutt himself is immune to this.
- Second Person Attack:
- "Chicken Ball Z" begins with Mandy repeatedly punching Billy in the face at a karate dojo, portrayed this way.
- Towards the end of the episode "Sister Grim", the giant nun (formed by many regular sized nuns) sends Grim home with a big punch after they find out that he wasn't actually a nun the whole time.
- At the end of the episode "Hoss Delgado: Spectral Exterminator", Hoss fights a werewolf. They jump up, and the camera pans, Matrix-style, to (almost) the POV of the werewolf. Hoss fires his slime gun at the werewolf, filling the screen to a fade-to-black.
- Shape Shifter
- Ship Tease: The topic of Billy and Mandy getting married seems to come up often. In one episode, he even kissed her.
- When Mandy finds out that Billy fell in love with a seemingly normal girl. Cue a shocked expression, a slightly saddened expression, then a total verbal beatdown of how desperate the girl is. If it were anyone else other than Mandy, this troper would call her jealous.
- Whenever Irwin tries to kiss her or woo her she either gags and literally throws up or gets angry and punches him. When it is suggested in one episode that Mandy use her feminine wiles on Billy, she's not really that against it and she didn't gag or throw-up. In fact, she moaned and got a little annoyed but compared to her normally extreme reactions-especially when Irwin is involved-this was nothing.
- Shout-Out: Now has its own page.
- Side Effects Include...: In "Nergal's Pizza", Nergal tells Jr. to spike Granny Grim's pizza sauce with some "horrible ghastly elixir". When Jr. asks what it does, Nergal responds "I don't know, but it's ghastly."
- Snap Back: With gusto. A good third of the episodes end with characters dead.
- Soap Within a Show: Grim's favorite show My Troubled Pony.
- Sociopathic Hero: Mandy and Grim.
- Speak of the Devil: Lord Moldybutt. If you say his name, something breaks nearby, whether it be a tree falling, or a door knob falling out. It doesn't matter who's affected by it, (because once, a tree falls on him) it will happen.
- Spider People: The title character of the episode "The Wrath of the Spider Queen".
- Spiritual Successor: To The Ren & Stimpy Show, right down to copying both characters (Gender not necessarily withstanding.)
- Spotting the Thread: When Nergal Jr. tries to impersonate Mandy he screws it up by smiling, something she would never do, and Billy picks up on it immediately. No one seems to notice that Mandy suddenly got glasses for no apparent reason, though.
- Squashed Flat: In Billy and Mandy's Big Boogey Adventure, the villains' boat gets flattened vertically in one scene, and then falls over on its side.
- Sudden Anatomy: In one early episode, Mandy spontaneously grows nostrils when Billy picks her nose. Later on, however, her not having a nose is actually a plot point.
- Suddenly Fluent in Gibberish: In the Underfist special, Irwin pleads with Hoss, Skarr, and Jeff that, among other things, Mindy was kidnapped by a marshmallow bunny. However, his hysterical Inelegant Blubbering couldn't be understood by anyone save Jeff, who speaks "crybaby."
- Super Window Jump: Played with.
- Swiss Army Appendage: Hoss Delgado's prosthetic hand. It's typically a metal hand, chainsaw or Arm Cannon. (The video game even refers to it as a "Swiss Army Hand" in Hoss' bio.)
- Tarot Motifs: During the credits. Not named as such, but Billy is clearly The Fool, Mandy The Hierophant, and Grim... well, let's just say he ain't the Wheel Of Fortune.
- Tastes Like Diabetes: The Happy Huggy Stuffy Bears and Enchanted Forest from "The Crass Unicorn" are In-Universe examples of this trope. They get disgusted reactions from Mandy and Grim.
- Team Pet: One-shot character "Admiral Wolverine Lightningbolt", an alien whom Billy named because "those are the three coolest words in the universe."
- Territorial Smurfette: One episode featured a tribe of Smurf expies and Grim tried to capture them. One of his attempts consisted on disguising himself as a female of their species, resulting on him getting a beating from their Smurfette.
- Thick-Line Animation
- Third-Person Person: Dracula.
- Those Two Guys: Grim and Mandy often play this part in the episodes that revolve around Billy.
- Toilet Humor: Constantly. In "Hog Wild", Billy, fed up with rules, tries to fart on Grim. Instead, he soils his pants.
- Actually, this is at near-Running Gag level with Billy. You'd be hard-pressed to find an episode without at least one occasion of Billy needing to use the toilet or talking about how he soiled himself. Very common random joke for this show.
- Tongue on the Flagpole: Billy gets his tongue frozen to Santa's sleigh in the Christmas Special.
- Too Dumb to Live: Billy, on a good day.
- He somehow managed to get -5 in a IQ test.
- Too Spicy for Yog Sothoth: Two examples act as joint Trope Namer.
- Transplant: General Skarr from Evil Con Carne, who's nobly trying to give up a life of world domination for suburban normalcy. He's fond of garden gnomes and cornbread.
- "Real corn makes it SPECIAL."
- The Ugly Guy's Hot Daughter: Gender inversion, Sperg and his mom.
- Vague Age: None of the main kids' (Billy, Mandy, Irwin, etc.) exact ages are ever mentioned (though they appear to be around 11 or 12), and their school seems to be a combination of both elementary school and junior high. Billy mentions repeating the 2nd grade again, but that might have been just a one-off gag.
- Valley Girl: Eris was portrayed as one in her first appearance. To explain the change regarding her later characterization, Grim mentioned her going through a "Valley Girl phase."
- Verbal Tic: Irwin, yo!
- Villainous BSOD: In the football episode, Mindy has one when she and her cheerleaders are cast aside by the coach in favor of Mandy, despite Mindy's serious threats against her.
- Villain Decay: The Grim Reaper, In-Universe.
Grim: I used to have a chariot of four-hundred horses. My arrival on the scene would be a raging thunderclap of fear! Now it's, "Hey, have you seen Grim?" "Yeah, I think he's wedged between a history textbook and a tuna fish sandwich!"
- Villain Song: Mindy gets one in Underfist.
- Was It All a Lie?: Parodied in "Scary Poppins". Being informed that Mandy is not related to him is such a shock to Billy's Dad that it causes him to question whether anything in his life is true, including his real son and his marriage. Granted, Billy's dad is an idiot.
- "Well Done, Son!" Guy: Jeff the Spider endlessly aims to please no matter how many times the arachnophobic and Too Dumb to Live Billy tries to murder him.
Jeff: *while repeatedly jabbed in the eye with a large stick* Why won't you love me, Dad? I'll be whatever you want me to be!
Billy: I want you to be dead!
- Weirdness Magnet: Anyone and anything associated with Grim.
- Lampshaded in the crossover with KND, Numbuh 1 states all the weird stuff happening in Endsvile is why the KND prefer to stay away from that area.
- Wham Line: "Irwin's Grandmama is Dracula's wife?!"
- Who Wants to Live Forever?: Jack O'Lantern, although in his case it's less "immortality sucks" than it is "immortality having to wear a pumpkin for a head sucks".
Jack: 364 days a year, and I can't even go to the Ding-Dong grocery store to buy pudding! And do you know why?!
- Who Writes This Crap?!: Played for Laughs occasionally, where it cues to a monkey or a baby in front of a typewriter.
- Why Did It Have to Be Snakes?: Billy has severe arachnophobia, which is bad news for Jeff.
- He also has a fear of clowns and the mailman.
- Irwin's greatest fears are stand-up comedy and bears. Cue him getting mauled by them very quickly.
- Mandy's greatest fear is the possibility that she will grow out of being who she is, and actually become nice... and furthermore, marries Irwin.
- Grim and Billy believe that Mandy is afraid of ice skaters, but Mandy denies it, she just "doesn't trust the way they spin".
Grim: Like that ice skating thing?
Mandy: It's not a thing, alright? It's not... a thing!
- With Friends Like These...: Grim, Billy and Mandy's supposed "best friend," is normally treated like little more than a slave, and openly mentions on more than one occasion that he often fantasizes about killing them.
- Wizarding School: Dean Toadblatt's School of Sorcery.
- What Happened to the Hamster?: Remember how this all started with Billy's hamster? Never heard from again except in flashbacks.
- There is one episode where it saves Billy's more visible cat Milkshakes from a fire or something, only to be eaten. It breaks free in the end and Billy mugs the camera to announce "Oh, come on, like we'd really do that."
- Yandere: Nergal Jr. (although a sweet and lonely child) can become so obsessed with making friends that if someone befriends him, he'll do anything to make sure that he is their best friend. Usually, he doesn't realize how angry and jealous he can get.
- His father was a bit like this himself.
- The rabbit from the wishing skull episode.
- Your Brain Won't Be Much of a Meal: The brain-eating meteor doesn't find anything in Billy's head. Human and Martian zombies also find nothing appetizing in Billy's head.
