History YMMV / TheGrimAdventuresOfBillyAndMandy

* MemeticBadass:
** Harold, with fans pointing out how he's an ex-Navy Seal who was smart enough to get into Harvard Law, dry shaves with a steel razor while biting down on a piece of wood, and once beat the shit out of a Viking that was wearing Billy's clothes.
** Billy himself is no slouch too, thanks to him taking over Asgard in the same episode that Harold fought a Viking, being able to run as fast as a car, becoming a crimebusting CIA agent, and genuinely striking fear into the heart of Mandy and Grim whenever he's sufficently enraged.

* MoralEventHorizon: Mandy crosses it in ''The Grim Adventures of the KND'' when she tortures Numbuh 1, steals his identity, transforms the KND into a dictatorship, and later [[spoiler: willingly merges with the Delightful Reaper to reap the souls of children across the multiverse.]]

* WTHCastingAgency: Creator/GilbertGottfried as ''SantaClaus''. Then again, [[Administrivia/TropesAreTools that was probably intentional]], given [[QuirkyWork the standards of the series]].

** THIS MOVIE ISN'T STUPID! '''''[[NoYou YOU'RE]]'' [[NoYou STUPID!]]''' [[labelnote:Explanation]]Billy's angry retort to Grim after the latter criticizes a videotape he is watching has been repeatedly quoted by fans to defend any movie with a polarizing critical reception.[[/labelnote]]

* UnintentionalUncannyValley: [[UnnamedParent Sperg's Mom]]. Though she is not most egregious example of this, her comparatively more realistic look does clash with the more stylized look of the rest of the cast.

%% ** Sir Raven

** Pretty much all of "Little Shop of Horrors", a MusicalEpisode devoted to Voltaire singing "Brains". It’s the best known scene of original music in the series, and was popular enough to be adapted as the FinalBoss fight of the video game.

** The show also has a sizeable Japanese fanbase due to its dub. Many Japanese fans also like Mandy, deeming her cute despite her melancholic and cold personality. Additionally, the Japanese dub portrays Mandy as more of a serious ActionGirl, rather than just evil.

** Billy, at times. While he can drive people up, the fact people, especially Mandy, can be cruel to him on a regular basis, no one shows any concern for him when he is danger or needs help, and has two mentally unstable parents who can be at times neglectful to him, the guy deserves some sympathy.

* CargoShip: Grim and his Scythe. [[ICallItVera He calls it "Jodie".]]

** How unintentional is up for debate, but Irwin, Pud'n, and Sperg in "Tricycle of Terror" could fall into this trope. While it could be argued that Billy was indeed too old to be riding a tricycle, this doesn't excuse the fact that all three of them sadistically mock him for it, with Sperg taking it a step further by giving Billy a brutal wedgie and then throwing "Trykie" off a cliff while Billy can only watch and beg helplessly. All three of them gloat about [[EvilFeelsGood how good it felt]] after doing so (Pud'n even calls it "awesome", the little shit). When the haunted tricycle violently retaliates, they all have the nerve to expect sympathy from both Billy and the audience, with Pud'n obnoxiously calling Trykie a "mean old tricycle", conveniently ignoring the fact that they are all [[AssholeVictim Asshole Victims]] who went out of their way to deserve their fate. It also doesn't help that Trikey, unlike {{Literature/Christine}}, didn't attack people for simply being close to Billy and only attacked Grim out of self-defense.

** Similarly, in “WishBones” Sperg wishes to become a woman so he can get into the girls’ bathroom, but gets mocked by the girls there for his appearance can be paralleled to transphobia.
