Lemongrab: STOP SCREAMING!!! WHY ARE YOU SCREAMING?!?!
Hayley in early seasons of American Dad!. Her initial role in the show was to act as a Not So Different Liberal rival to her extremist Republican father Stan, often proving to be just as self serving and vindictive as he is. She also has overly feminist ideals, despite often being implied to be a slut who treats her boyfriends like crap (as an extra bonus, she dumps Jeff apathetically on a frequent basis, though throws into a feral rage the one instance he did it to her).
One of the reasons Sam Manson is considered The Scrappy in Danny Phantom is because of her hypocritical behavior. She says she opposes violence yet is fine with hitting her friends, namely Tucker, even when it isn't needed. She despises forcing beliefs and opinions on to other yet forced the entire school to eat her "recyclable organic matter" because "we don't need meat". She scolds Danny for using his ghost powers against powerless school bullies yet she's okay with causing millions of dollars in property damage to a dealership because they were selling eco-unfriendly trucks.
Danny's archenemy, Vlad Plasmius, may count as one too. Despite his claims that all he wanted was to be loved, he treats the only two people who showed him any kind of love or admiration like dirt all because they weren't the wife and son he always wanted. He instead obsesses over a woman, a married one at that, who doesn't even like him as a friend and doesn't care how she actually feels and gaining his teenage archenemy as a son.
Princess Clara from Drawn Together. She presents herself as a racist religious fundamentalist who believes that masturbation and homosexuality are evil, yet she has no qualms about dressing in thongs and doing erotic dances to entertain men.
Brian in Family Guy has a nasty tendency to be a huge hypocrite. He claims he likes women for their personalities but we only ever see him dating bimbos, and even then only in short-term relationships. He has plenty of liberal opinions but we never see him DO anything about them. He has no obvious job and just leeches off the Griffin family. He drinks and smokes quite heavily. In "Dial Meg For Murder" he voices his opinion that the prison system has turned the innocent Meg into a hardened criminal but it's obvious that nobody, including him, went to visit her during the three months she was in prison. Quagmire eventually calls him out on how he really can be a prick. Glenn points out he himself has plenty of problems, but at least headmitsthem.
However, Quagmire's attitude comes across as sanctimonious as he condemns Brian for all sorts of things, but Quagmire regularly does far more atrocious stuff than Brian.
Quagmire was criticizing Brian for his hypocrisy, for his putting on a mask of goodness over the filth inside him (cf. "whitewashed tombs" from the Bible).
Peter Griffin in general.
Lois is also like this. She criticizes Peter for drinking all night and does it herself just because of a curfew and smokes pot, but criticizes Brian for it.
Given the completely immorality of the entire cast, it's pretty much granted that any character that tries to pose themselves as The Straight Man will end up looking like this.
Laney Penn from Grojband dislikes "Boy-Crazy Girly Girls", but she has a huge crush on Corey and occasionally has shown a hidden girly side, also she gets mad when Singer Candy Jams dosen't have the creative mind to write her own songs when...well you get the point.
Trina Riffin hates Kin for being a nerd, but she's secretly a nerd herself, also in the episode "Dueling Buttons" she's shown to be singing and enjoying music.
In the last few episodes of the Nineties Iron Man series, the Mandarin uses the Heart of Darkness to shut down all advanced technology in the world. After the Heart and five of his rings of power are destroyed, the Mandarin retreats into his fortress. When Tony catches up with him, he finds the Mandarin decked out in a suit of Powered Armor. Tony even notes the hypocrisy. The Mandarin retorts that while he may like the idea of world without technology, he's no fanatic.
Cadmus. They do have a point that the Justice League is a potentially dangerous organization. But they often go out of their way to straight up attack them, instead of preparing for their possible betrayal. They're afraid of the Justice League crossing the line and creating huge problems, when they themselves have already done so.
The reason they say they're better? They obey the government and aren't a bunch of loose cannons. And when the BFG fires on Earth, (which was caused by Luthor hacking the Watchtower's computers), orders from the president himself told them to wait before taking action while he looked into the situation. What do they do? Wait a while, and then put a loose cannon in charge of an army to kill the entire Justice League, without waiting for government approval.
General Wade Eiling, who goes after the Justice League because he believes metahumans are dangerous and can't be trusted. He ends up becoming a metahuman himself, and goes after a group of heroes who have no powers (admittedly, he was looking for Superman, but he wasn't available). When a nearby civilian points out that he's the only one at the site of the battle with powers, he concedes the kid's point and leaves, and is not seen again.
Lex Luthor has cancer from manipulating kryptonitefor years. He blames it all on Superman, saying that he would never had caught the disease if Superman didn't oppose him the first place.
The Legend of Korra has Amon, who despite being the leader of a powerful anti-bending movement called the Equalists, can take a person's bending away. But to do that, he at first appears to use "energybending", which is the oldest form of bending, and then there's The Reveal that it's actually bloodbending, the most dangerous form of bending on the planet. And this makes Amon Tarrlok's brother and the bloodbending crime boss Yakone's other son.
The Equalists themselves could be seen as a group of hypocrites. For all of their rage about benders oppressing them, they have endangered and threatened other non-benders, even Hiroshi Sato had threatened and later attempted to kill his own daughter for refusing his side and with Amon, became the oppressors themselves. In general, the Equalists are made up of people who are genuinely hypocrites and those who sincerely believe in their message.
Unalaq, the Big Bad of Season 2, is this in spades. He goes on about how the world lacks spiritual balance, and yet he created a spiritual imbalance to have his brother banished so that he could become chief of the Northern Water Tribe. He also paints Tonraq and Tenzin as poor fathers and mentors for letting their children get in harm's way and controlling every aspect of Korra's life, yet he shows no regard for the lives of his own two children, even telling his daughter to leave her brother to die, and manipulated Korra into helping him. Finally, he accused the Avatar of causing chaos for separating the spirit world and material world by sealing Vaatu, yet he's trying to free Vaatu, the very incarnation of chaos, and has done nothing but cause chaos himself.
Most of the Mane Six are this in the episode "The Mysterious Mare Do Well". Sure, they weren't happy with Rainbow Dash getting a bit of a big head over getting praised for saving lives, but they were doing it just to spite somepony. And they bragged even more about it just to make her feel worse. Well, With Friends Like These......
Then there's "Ponyville Confidential". The citizens of Ponyville enjoyed reading about the gossip that was spread about each others, but when they were gossiped about, they got angry.
In Twilight's Kingdom Part 2, despite continually showing bitterness and hate for his brother Scorpan betraying him to save Equestria, Tirek has no qualms about stabbing Discord in the back for power.
From the The Simpsons episode "Homer vs the City of New York":
Bart: Don't judge a place you've never been to. That's what people do in Russia.
In the episode "The Boys of Bummer", Joe LaBoot chides Bart for losing a baseball game by missing a ball - completely ignoring the fact that he himself did the same thing years earlier.
Marge is often a hypocrite throughout the series, like being opposed to the violence of Itchy and Scratchy, but having no problem with the nudity of Michealangelo's David.
Not quite hypocrisy in that instance, because Itchy and Scratchy' (a) is geared toward kids and (b) causes kids to act out inappropriately, for example, leading to Maggie's attacking Homer with a mallet. None of this is true of Michelangelo's David.
Seriously played for laughs in "Bart's Girlfriend". During one of Rev. Lovejoy's boring sermons, Bart starts playing with a Troll Doll; Marge snatches it from him, saying, "I don't want you playing with something that has such bizarre hair!"
In the AIDS episode of South Park, when Cartman and Kyle both wind up getting HIV throughout the episode Cartman comes up with a stupid catchphrase that "he isn't just sure, he's HIV positive." This leads Kyle to angrily berate him that AIDS is serious and no laughing matter, which would probably have some deeper impact if it wasn't for the fact that earlier in the episode he was continuously laughing at and mocking Cartman for getting HIV.
To be fair, his mocking Cartman was out of hate he had for him and joy at his possible death.
In the early seasons, Cartman was shown to be a homophobe and made fun of Stan's dog for being gay, yet as the series progresses Cartman has shown signs of being ambiguously gay to the point where he makes himself look bigger and gayer than Big Gay Al due to the Hoyay he has with Kyle and Butters.
Eddie Brock/Venom in The Spectacular Spider-Man. While it wasn't wrong for him to be angry with Peter, his actions as Venom don't paint him any better. He accused Peter of being a user and causing people's suffering, not caring who he hurts, yet proceeded to do the same as Venom, such as kidnapping Gwen, leaving her in a position where she could fall and die, traumatizing her in the process, and kept Peter from saving her. While Peter did cause people problems, they weren't intentional and he felt bad for it. Venom did it deliberately, even stating he'd sit and enjoy while Peter would be unable to save his loved ones from his enemies should he make Peter lose his powers and reveal his identity to the world.
Pumyra in ThunderCats (2011). Even ignoring she wants revenge on Lion-o for not saving her because he was too far away to see her or hear her calling out to him, she is willing serving Mumm-Ra to do it. Mumm-Ra was the one who caused the attack on Thundera, the same attack that got her killed in the first place.
Many of the non-Mumm-Ra follower antagonists see the cats as opressors and barbarians (understandably so, as the cats were The Empire until the events of the pilot), yet have no issues opressing not only the cats, but also other species, and act like the animals they are (literally). Perhaps the worst is Vultaire, who in addition to this is also a petty Sore Loser who reacts to failure much in the way he accuses the cats of acting, and has two episodes worth of pretentious ethical rhetoric and then betrays his own civilisation to Mumm-Ra when it becomes clear he will have benefits for that. And that the cats will suffer.
In Total Drama, pretty much every character commits an act of hypocrisy at some point. Notable ones include:
Gwen: When Heather kisses Trent in front of Gwen (who was dating Trent at the time) as part of a plan to get Trent eliminated and it's regarded as one of her most underhanded ploys to win and pretty much cemented the dislike Gwen and everyone else had for her. However, this doesn't stop Gwen from legitimately stealing Duncan from Courtney in the third season.
Courtney: The Queen of this trope; spends the first season ranting about rules and order, before becoming the Big Bad of the next season who has on several occasion done attempted murder.
When Heather found out that Leshawna tricked her team into giving her the spa reward in Action by fake crying, Heather gets mad to the point of almost attacking Leshawna. Heather was theManipulative Bitch in the first season and did stuff that was just as bad.
