From "Too Old" to "Lemonhope Story", the Earl of Lemongrab from Adventure Time becomes this. Special mention to the facts he stole his children's food, and ate his brother whole.
Roger Smith. Stan constantly reminds him he is out-of-shape, which is mostly attributed to eating all the family's food. Some of his personas are even depicted as obese.
Stan Smith himself is generally muscular, but some episodes do depict him as plump, which is combined with being a ruthless Jerkass.
Barry, Steve's friend, becomes a ruthless, calculating psychopath when he is unmedicated. Otherwise, he is usually just a Fat Idiot.
Animaniacs: Pesto in the Goodfeathers segments. Of the three pigeons, he's not only the chubbiest but also has the foulest temper. Every time Squit compliments him or gives him advice, Pesto tends to take what Squit said as an insult and go on an irate rant before beating Squit up.
Caractacus P. Doom, the main villain of Avenger Penguins, was as portly as he was evil.
Crime boss Rupert Thorne was a recurring villain, and was overweight.
One episode had Bruce Wayne, with amnesia, kidnapped and forced to work in a mining camp by Boss Biggis, a white-suited obese man who was always munching on food. When one of the man's henchmen tried to remind him that the exhausted slaves have to eat, he replied, "I have to eat. They have to work."
Harvey Bullock is a downplayed example. He's repeatedly shown to be rude, filthy, in love with donuts and a general mess, but he's an honest cop and just as dedicated to taking down criminals as Commissioner Gordon and Batman, even if he butts heads with Batman.
Chief Rojas is overweight, incompetent and self-righteous. He thinks what he says goes and helped to ruin the life of one of his officers, Ethan Bennett, just because Bennett supported Batman.
Cluemaster is portrayed as morbidly obese, in stark contrast to his physically fit physique in the comics.
Beetlejuice: Recurring character Mr. Monitor is a Neitherworld television executive who is rather hefty and willing to screw Beetlejuice over or put his afterlife in danger if it means getting good ratings.
Lawrence Limburger from the original series. It's implied obesity is a sign of high rank in Plutarkians (being Planet Looters who strip other planets bare for natural resources), with most of the seen Plutarkians being very bloated (Limburger's sister even mentions going to the Plutarkian "fat farm" and wanting to get there before all the good fat is gone). The only skinny Plutarkians seen are Marshal (Limburger's pre-teen hellion of a nephew), One-Eyed Jack Monterey (a Plutarkian agent stationed in Las Vegas), Gutama Gouda (a Plutarkian agent stationed in Los Angeles), Dominic T. Stilton (Limburger's former superior from the episode "Once Upon a Time on Mars") and a lawyer named Perry Provoloni.
The 2006 revival has one of the major villains being a Corrupt Corporate Executive named Ronaldo Rump, who is mainly fat because, as his name implies, he has a huge rear end.
The Boondocks has several overweight characters, and most of them are unpleasant.
Captain Simian and the Space Monkeys had a minor recurring villain named Apax, who was an obese alien who enjoyed imprisoning people and exploiting them for his own ends.
Shogun Roquefort, the fat Cheese Shogun. However, despite being a bastard (he blackmails restaurants into giving them their cheese and forces both kids and adults alike to work as slave labor in his cheese mines) he's really not a very competent villain at all. His Mooks are competant fighters, while he knocks himself out by hitting his head on the ceiling when confronting Numbuh Two.
Chester, an obese man who frequently comes up with get-rich-quick schemes that revolve around exploiting and/or harming children.
Heinrich Von Marzipan, a rival of Numbuh Five who is chubby and often out to obtain candy by any means, even if he has to steal from other children or kill the class pet of a bunch of first-graders to do so.
The candy pirate Stickybeard, who's tremendous and loves stealing candy from children.
Grandma Stuffum, an overweight Cordon Bleugh Chef who tries to force children to eat her horrible food.
The Crazy Old Cat Lady, who's even pointed out by the Toiletnator to be "portly" when he mistakes her for a disguised Numbuh Two in "Operation: F.L.U.S.H."
Mr. Mogul is the hefty head of the Rainbow Monkey Corporation who cemented his status of repugnance in his debut episode "Operation: R.A.I.N.B.O.W.S." when he manipulates Numbuh Three into helping him hunt real Rainbow Monkeys with the intent of supposedly killing them and making them into toys. He was also willing to do the same to Numbuh Three to prevent her from squealing on him.
Former class president James Nixon McGarfield, who was initially on the Kids Next Door's side, but ended up corrupted by Father.
Subverted with Professor XXXL, who's overweight, but isn't really evil and only wants to create the perfect snow cone. He only attacks the Kids Next Door because they always think he's up to no good.
Toot from Drawn Together, who is overweight and bitter about it. She's shown to eat people, and to consume too much food. Becomes more sympathetic later.
So overweight, in fact, that at one point it takes her nervous system about two minutes to relay pain to her brain. Said pain was a sword Xandir stabbed into her back as a bet.
There was also an episode where she ended up on an island as a beached whale.
Recurring villain King Chicken is noticeably plump.
Duckman's Uncle Mo is overweight and is such a bastard that he makes his grouchy and perverted nephew look like a saint.
In the Dynomutt, Dog Wonder episode "Lighter Than Air Raid", a very fat, nefarious villain called “The Blimp” hijacks a communications satellite in order to loot Big City by using his “blimpray” to turn its citizens into fat, helpless, floating human balloons.
Peter Griffin's tendency to invoke this trope is probably the most obvious difference between him and Homer Simpson. While Homer can gobble down platefuls of food for laughs, Peter's usually only shown in the same context as food when the point is supposed to be that he's a Jerkass.
One episode in particular stands out — Peter forms an awareness group for fat people discrimination, and every last one of them conforms to this trope, making disturbing groaning noises, busting out snacks every few minutes, and making excuses for all their actions. One half-dead fat guy actually interrupts the action to ask if he can eat a dead fat guy that's in the same room as he is.
In a cutaway scene from the episode Brian Sings and Swings, John Goodman is portrayed as this.
Son: Please, Daddy. Goodman: I told you, when I'm finished, you can have what's left! Son: There won't be any left. There's never any left. (Wife tries to snatch some food, only for Goodman to stab her with a fork.) Wife:(nervously) Happy Thanksgiving.
...which brings us to the other standout episode of this trope: When Peter gets a vasectomy and loses all interest in Lois, she starts pigging out, and he starts to make jokes about her weight... until said fat fetish busts out and breaks the bed.
Only averted sometimes by Chris Griffin and averted always with Cleveland (now a protagonist all his own), and Cleveland Jr., who are all fat but are also among the show's few genuinely decent tempered characters. Chris is with his dad in the Fat Idiot trope though, but he's still far less vicious generally. Cleveland is rather intelligent.
When Chris in one episode makes an attempt to lose weight, Stewie taunts and mocks him relentlessly. As the episode goes on, Stewie pigs out and eats more and more to taunt Chris with the food he cannot eat. This causes Stewie to gain lots of weight over time and as he gets bigger, he becomes more of a slob (he slams his face into a chocolate cake and eats like a pig), his girth breaks his high chair, and he grows so lazy to the point where his insults are lazily made and he falls asleep in the middle of it before he can finish his ice cream.
Hermes is the fattest of the Planet Express crew and generally doesn't seem to care whether his co-workers live or die. He also bullies Zoidberg on a regular basis. He has his good points, though.
New New York's mayor C. Randall Poopenmeyer is a bit pudgy and is usually shown to not be a good person.
Zapp Brannigan has a prominent gut and is a sexist pervert who thinks nothing of sending men to their deaths to save his own skin.

The episode "Less Than Hero" has Fry, Leela and Bender confront a chubby supervillain known as the Zookeeper.
All of the nudist alien scammers who are the antagonists of the first direct-to-video film Bender's Big Score have paunches, but Schlump is noticeably the fattest of the three.

One of the recurring villains in The Garfield Show is Mama Meany, an obese restaurateur who makes his fortune by selling cheaply-manufactured and barely edible excuses for food to cut down the expenses and ensure he gets more profits. He frequently ends up at odds with Garfield due to trying to run the local Italian chef Vito out of business.
Coach Cadaver is an obese gym coach who is frequently very rude towards Max Schneider's class and is very vocal about hating Schneider for being the school's only human teacher.
"Goodbye Gravedale" has a misunderstanding result in Max Schneider leaving his class, with two substitute teachers taking his place who are both overweight and care more about making things grueling for the students than teaching them. The first is Mr. Gross, a Jabba the Hutt lookalike whose gluttony is used against him when the class trick him into eating until he blows up, the second being a pudgy dragon named Miss Burns who isn't above using her fiery breath to intimidate the kids and goes so far as to make them take 12 tests in one day.
Harley Quinn (2019): The cartoon's interpretation of the Condiment King is noticeably chubby and spends the majority of his screentime being a complete asshole to Kite-Man.
Principal I. M. Greedyguts on Jacob Two-Two, a Villainous GluttonDean Bitterman who frequently embezzles the school's budget and enjoys making his students miserable for his own selfish purposes while also hoarding junk food and helping himself to grand feasts on a regular basis.
Johnny Bravo has more than a few miscreants and scoundrels who happen to be overweight.
"Super Duped" has Johnny fight an obese villain dressed like a clown called Sweet Cheeks, who steals candy and attempts to turn Little Suzy into chocolate with a caramel center before Johnny accidentally hoses him down, causing him to melt.
The title character of "The Sensitive Male" is a bit portly and at the end of the episode admits to Johnny that his sensitivity act is insincere and only used to get women to like him. After learning this, Johnny proceeds to squeal on his deception to the women he got to love him and they respond by preparing to punish him for manipulating them.
The appropriately named titular character of "Moby Jerk" is a pudgy merman who enjoys taunting Captain Spleen.
"Hunted!" has Johnny Bravo hunted by an obese man named Colonel Beauregard Fatman.
The protagonist of the animated short La Faim. While he is not a particularly nasty person, he disgusts the audience due to his complete and utter selfishness; he cares about absolutely nothing in life outside of his own pleasures. His gluttonous gorging gets more and more over-the-top as the short goes on (facing a full banquet table, he becomes an Eldritch Abomination made of mouths and arms so he can eat it all, and then becomes a steamshovel as he devours the table itself), and he morphs from a handsome young man into a morbidly obese slug. Finally the short ends when the man realizes the cost of his lifestyle: millions of children across the world are starving. He is surrounded by starving waifs, who proceed to...well, you can probably guess from here.
The Loud House: Flip has his moments. Best exampified in the season two episode "Snow Way Out" where he tells the Loud kids that he'll only get them out of the snowed in Burpin' Burger if they give him the winning wrapper. When Lana refuses to give it up, Flip instead escorts the cashier out.
In "Inspiration Manifestation", Rarity is commissioned to build a puppet show theater for an overweight puppeteer. After her first attempt, the puppeteer brutally criticizes the work she did and he tries to squeeze into the theater.
Diamond Tiara's abusive mother, Spoiled Rich. She's pudgier than the standard mare body type, but she's still nasty.
"Father Knows Beast" introduces Sludge, a overweight slob of a dragon claiming to be Spike's father. He's not.
In the The New Adventures of Batman episode "A Sweet Joke on Gotham City", the obese villain Sweet Tooth and his gang of fat, candy-addicted kids turn Gotham City’s water supply to chocolate syrup, then hold it for ransom.
The Oblongs gives us Helga, a rude, ugly, mobidly obese little girl with delusions of grandeur. At least, they connect it to being underprivileged (she can only affored to eat thrown out wedding cakes, she lives next to an abandoned factory...) And she is still awesome!
OK K.O.! Let's Be Heroes has Lord Boxman, who is rather rotund and frequently sends robots to try and destroy Lakewood Plaza Turbo out of a sheer hatred of friendship.
Pete in all of his roles in Disney stuff is incredibly fat and an incredible bastard. The degrees of bastardy have varied over the years, but he always qualifies. Averted with his son P.J., in Goof Troop, who's shaped like him (but with less of the ugly) and is a really nice kid.
Miss Finster, Gellman, and Kurst the Worst in Recess.
There's also Koreo, a thuggish fifth grader who hangs around Lawson.
From Rocket Power we have Pi Piston, one of Lars's friends.
Some of the episodes in the syndicated season had the Ghostbusters deal with Lt. Frump, a fat police officer who detested the Ghostbusters and took every opportunity he was given to berate them and put them down, though he did draw the line against arresting them under false pretenses.
One of the few ghosts who appeared in more than one episode was the Ghostmaster, a very powerful ghost who despised the Ghostbusters and was incredibly obese.
The Slimer! segments featured Professor Norman Dweeb, an eccentric scientist who is obsessed with capturing Slimer to prove he's better than the Ghostbusters and is a little on the chunky side.
The episode "Partners in Slime" had the Ghostbusters deal with a red-skinned Jabba the Hutt-esque gangster ghost named Pozo.
Ed Bighead isn't as fat as the other two, but he still counts, going as far as hiring Rocko at Conglom-O in an attempt to kill him in the episode "Canned".
Mr. E in Scooby-Doo! Mystery Incorporated. He was much skinnier as a teenager and is in shape in the new timeline, in which he's very Steve Jobs-esque. This makes sense, considering he's actually Ricky Owens, who's clearly meant to be Shaggy's analogue in the original Mystery Incorporated. The adult Mr. E gives us an idea of what Shaggy would look like if his famous love of junk food ever caught up with his physique.
General Specific from Sheep in the Big City is a bit rotund and is always trying to capture Sheep so he can be used to power a ray gun against his will.
Homer Simpson, despite what one may initially think, mostly averts this trope. When 75% of the entire cast is fat — Springfield is the fattest city in America! — the fat people come in all temperaments. Everyone who's fat has their Fat Bastard moments, but it isn't always consistent, especially with the Negative Continuity.
There are near-consistent straight cases, though, even if the fat and the bastardy aren't directly related. Mayor Quimby's girth could be taken to represent him being one of the "fat cats" (a derogatory term for over-privileged and corrupt politicians). Jeff Albertson the Comic Book Guy is nasty and self-defeatingly pompous, and is not above using profiteering to make money. Fat Tony belongs to an evil profession. Nelson is a big fat bully (though he does have some moments of decency, especially when he's interacting with Lisa).
Homer can show it at times, like the episode where Homer selfishly and stupidly became horrendously obese just to be able to work at home and avoid 15 minutes of exercise a week. (But he did become the hero in the end.)
Slightly inverted in that the most actively evil characters on the show, Mr. Burns and Sideshow Bob, are thin.
One example of how this trope is zig-zagged in the show is the trio of bullies: Jimbo and Dolph are thin, while Kearney is fat.
The "Nightmare Cafeteria" segment in Treehouse of Horror has the teachers at Springfield Elementary killing the students and serving them for lunch. By the end of the short, Edna Krabappel's shown to have doubled in weight and is not only discretely trying to fatten up the remaining kids for richer meals, she has one of them sent to "detention" because a pencil fell off his desk.
Pictured above is Lord Balthazar from The Smurfs (1981). Gargamel's godfather, he's a more competent, far crueler wizard who was overweight. Something of an Upper-Class Twit, it was suggested that he had fondness for rich foods.
Eric Cartman. Most notably in two episodes where 1), during his family reunion, all of his family members, save for his mother and grandmother who are thin and caring, are fat annoying slobs. 2) Where Eric from the future, who lost weight and became a better person in general (and wealthy to boot), came to the past to tell Eric to be a good human being. Eric (thinking it was a trick) delivered the generic "screw you" line and said he would stay the way he was, after the other characters were out of view the future Eric transformed into a dirty obese mechanic as a result of his younger self not "changing for the better".
Heidi: Oh, what's the matter, Kyle?! Don't want me around 'cause you had the hots for me and I shot you down?! Kyle: I would NEVER have the hots for the person you are now. (This surprises Heidi)
Rob Reiner in the episode "Butt Out" uses propaganda to point out the dangers of smoking while ignoring his obesity to the point he needs butter to squeeze out of his limo.
Patrick Star occasionally shows traits of this, especially in later episodes thanks to Flanderization, "Rule Of Dumb" is a very extreme example where he goes mad with royal power.
Mr. Krabs may also count at times, though less emphasis is put on his rotund build for the most part.
Bubble Bass is one of the fattest recurring characters on the show, and he's undeniably proven himself to be quite a Jerkass in the episodes that focus on him. Fortunately, he's also depicted as being somewhat pathetic and he falls victim to Laser-Guided Karma in all of them.
Oleander, a zaftig villain from Sushi Pack, although she's only a villain because she's a foodee and wants to eat the Sushi Pack (who don't help things by describing themselves as "bite-sized bits of bravery" and "finger foods of freedom").
Tales from the Goose Lady had its take-off of Hansel and Gretel reinterpret the two children as Hamsel and Grande, who are a pair of obese children who torment the witch by eating her gingerbread house in spite of her protests and siccing a woodsman on her whenever she tries to stop them.
Krang from Teenage Mutant Ninja Turtles (1987) plays with this, and Stout Strength as his android body is an overweight looking humanoid, however the suit itself was never shown to be sentient, or evil in itself. The Ninja Turtles even made use of it at times.
Burne Thompson, the grumpy editor, and April's grouchy boss is portrayed as one in the toyline along with Fat Slob which exaggerates his overweight body by giving him an unbuttoned shirt, portrays him chewing with his mouth open, and holding a giant sandwich.
The 2003 cartoon: original villain Garbageman is a grotesquely obese man covered in food-stains, and drools who lives on a garbage island, and enslaves the homeless to be his subjects. Due to his weight, and having no legs, he rides around in a tank.
The 2012 Ninja Turtles: Vic was an overweight man in an undershirt who records the Ninja turtles for blackmail purposes, and is completely ungrateful when they rescue him. He gets turned into the mutant, Spiderbytez, a perfectly spherical Spider which shoots webs via farting, he blames the Turtles, and becomes a Super Villain.
Bebop wasn't fat in the 1987 version, but he clearly packed on the pounds in the updated 2012 one.
Three of the Gene Deitch-directed Tom and Jerry shorts gave Tom an overweight owner who routinely beat the tar out of him when he screwed something up. It wasn't pretty.
Sugar from Total Drama. A cheating, manipulative and jerk fat girl that eat anything that remotely looks like food. She doesn't care who she hurts in order to win, especially Ella.
The 2023 reboot gives us Ripper, who is not only a major Jerkass but also overweight to boot.
Dr. Killemoff's lackey Psycho, who once an episode would make a prediction of how the Toxic Crusaders would ruin Dr. Killemoff's latest Evil Plan, only for his boss to dismiss the prediction as preposterous before it inevitably comes true.
Tromaville's corrupt mayor Max Grody, who conspires with Dr. Killemoff's villainous deeds and is overall as repugnant as he is pudgy.
The Van Beuren Studios short "Scotty Finds a Home" has a pudgy dog vagabond break into the house of a young cat and his grandmother to force them to give him their food before he is chased out by the non-anthropomorphic Scottish terrier the younger cat befriended earlier in the short.
In the episode "The Troll" the titular antagonist gets fatter and taller when the Proud Warrior Race Guys Wander and Sylvia are with respond to him insulting them.
"The Sky Guy" has Sylvia and Wander consult a being named Neckbeard, a condescending douchebag whose rudeness is matched only by his obesity.
Principal Madman from Whatever Happened to... Robot Jones?. He's extremely hefty and is very cruel and intimidating to his students, especially Robot.
Tubbimura, the fat ninja from Xiaolin Showdown. A moderately competent (and relatively unsympathetic) villain, and quite certainly a Jerkass.
