Sir Swears-a-Lot in Western Animation.
- Arcane: For a TV-14 animated series based off a T-Rated video game series, Vi drops an F-bomb nearly every episode leading up the finale.
- The Boondocks:
- Robert Freeman is quite foul-mouthed, in particular with the N-word, having said "nigga" at least 46 times the day before in one case.
- His grandson Riley is also very foul-mouthed, being a rebellious juvenile delinquent after all.
- Stinkmeaner is easily the most foul-mouthed character, rarely saying a sentence that doesn't contain a curse or insult in it.
- Many characters in Castlevania (2017) liberally pepper their dialogue with profanity, most notably Trevor Belmont, often using "fuck" with the frequency most people would use a period. Another noteworthy example for just how bizarrely he's depicted is Death, who maintains a dramatically cold cadence but often drops F-bombs in very dry, deadpan manner, creating a tone that can be aptly summarized as "abrupt".Death: Why is it that only human hands can reach into Hell? Don't you think that's weirdly fucked up?
- The Cleveland Show: Larry Box, the "casually profane" mayor of Stoolbend.
- Parodied on Codename: Kids Next Door with Pottymouth, a rarely seen villain who uses child-caliber profanity in literally every sentence he utters.Pottymouth: Oh, go flush yourself down a pee-pee-hole, you toilet-paper-covered doody head!
- Dexter and Dee Dee's rude halves from the Dexter's Laboratory Banned Episode "Rude Removal".
- F is for Family:
- Frank Murphy is a very foul-mouthed individual, and his two sons Kevin and Bill are no better than him.
- In season 3, Bridget Fitzsimmons is revealed to be even worse, often cursing out everyone including her older brother Jimmy and her father, who are downright afraid of her. Frank's daughter Maureen even remarks, "She swears worse than my dad!"Jeffrey Dahmer: [to Bill] You hanging out with girls now, you fairy?
Bridget: GO SHIT IN YOUR FIST, FUCKFACE!
- Futurama:
- Bender as compared to the rest of the cast, to the point where the episode "War is the H-Word" had him unknowingly being weaponized with a bomb set to go off at his most frequently-used word: "ass."Bender: But before I go, I have one thing to say. Bite my shiny metal—
Fry: [bursting in] Stop! You can't say the next word!
Bender: Up yours, chump. I said it nine hundred and six times before lunch. - Mom, with bonus points for creativity."JAM A BASTARD IN IT, YOU CRAP!"
- Bender as compared to the rest of the cast, to the point where the episode "War is the H-Word" had him unknowingly being weaponized with a bomb set to go off at his most frequently-used word: "ass."
- Harley Quinn (2019): Harley drops a lot of F-bombs in just the first episode alone as if to warn that this cartoon is for a mature audience. Even she's shocked by the usage of Country Matters though.
- Velvet Von Black from The Haunted World of El Superbeasto is a female version of this trope, who literally cusses at least once in just about every single sentence.
- Kaeloo: Mr. Cat tends to swear a lot. Depending on the episode, it's either the Gosh Darn It to Heck! type of "swearing", or actual swears that get bleeped out.
- Boomhauer in the Hungarian dub of King of the Hill replaces his Verbal Tics with random cuss words, at least in the first six seasons. After that, the dub became clean.
- Yosemite Sam of Looney Tunes fame, though it typically comes out as incomprehensible gibberish. (Though voice actor Mel Blanc occasionally snuck some truly naughty words past the censors.)
- The titular character of the Danny Antonucci short Lupo the Butcher. The entire short consists of Lupo cussing a blue streak while cutting up ribs and accidentally dismembering himself. Even after he's reduced to a disembodied head, he continues swearing over the credits.
- In stark contrast to the rest of the Major Lazer cast, President Whitewall drops at least two F-bombs per episode.
- Metalocalypse: Pickles' brother Seth starting from his second appearance.Seth: Look at f***in' Dethklok in my f***in' house room! Ha! F***in' Mitch an' Bobby aren't gonna f***in' believe this. F***in' excited about you guys throwing me a bachelor party. F***. Oh, and by the way, [gestures to pregnant woman] this is little Amber, the love of my f***in' heart. Isn't she an angel?
- One episode of Phineas and Ferb is set in a steampunk past. The counterpart of Perry the Platypus in said episode is Sweary the Swan. Despite only making swan noises, everyone seems to be disturbed about the language he uses.Von Doofenshmirtz: Wow, do you preen your feathers with that mouth? They should call you Sw—oh! Oh, I get it.
- Robot Chicken:
- Palpatine in the Star Wars specials is probably the worst offender in regards to swearing. In particular, he uttered exactly nine usages of the F-word, six of which were in a chain, in the skit where Vader calls him at his office when telling him about the destruction of the Death Star. He later gives four usages of the F-word in a later skit detailing his bad day on the Death Star, two of which were, again, in a chain. In fact, with the exception of two Stormtroopers in Episode II and Lando Calrissian, a large majority of the more profane language (i.e. the ones that are required to be bleeped out when in syndication) are from Palpatine's mouth.
- The alien that keeps shouting, "DAMN IT, DAMN IT, DAMN IT!!!" in triplicate whenever his and his less blue partner-in-crime's plans go horribly wrong.
- We can't discuss Robot Chicken and not mention the queen of the guttermouths, Bitch Pudding
.
- Though almost everyone in South Park swears except for Butters (usually), most of it comes from Eric Cartman. Kenny McCormick is also known to have an incredibly filthy mouth (sometimes even more so than Cartman), but most of what he says is unintelligible anyway.
- Peridot from Steven Universe regularly and repeatedly calls people clods (or some derivative of the term). Given that gem society is highly caste-based, and the worth of someone is based on their gem's level of perfection, calling someone a clod is one of the worst insults possible—you're literally telling them that they're dirt, more worthless than even the lowest gems.
- Vanessa, Chris Griffin's future wife from Stewie Griffin: The Untold Story. It was more jarring when the movie was first released because no previous Family Guy DVD had uncensored language.
- Starfire from Teen Titans seems to frequently use not-so-family-friendly Tamaranian insults and words.
- Fowlmouth/Foulmouth from Tiny Toon Adventures lives up to his name by spewing out swears every second, with bleeps in the show, and "Dad Gum" in The Movie. One episode has Buster get him to clean up his act to be more likable to his crush Shirley. It's noted, however, that Fowlmouth keeps his language in check when there are little kids nearby.
