The Sonic the Hedgehog (SatAM) version of Doctor Robotnik, ...his "pretend to be good when it's practical" moments are a bit longer and more pronounced. However, he's inclined to boast about his evilness as though it was something to be proud of, especially when in the company of those he believes are evil and cruel.
Robotnik: I want the location of Lazar's lair. Name your prize.
Lazar's guardian: You intend harm to my master.
Robotnik: Oh, you wound me dear guardian! I merely want to wake the grand wizard and honour his evilness! We have much in common.
Rob from The Amazing World of Gumball became a villain simply because he had no other role to fulfill in Elmore. He went to the void for not having a defined personality until Gumball and Darwin literally suggest he become a villain.
Atomic Betty's Big Bad Maximus I.Q. literally refers to himself by the title of "Supreme Evil Overlord of the Galaxy" and believes himself to be the greatest evil genius in the universe. Hell, in one episode, he has a galactic politician kidnapped because the guy called him a villain and not a supervillain.
Azula from Avatar: The Last Airbender embraces the rest of the world's view that she's evil. She even calls herself a monster in the later episodes, but that's actually her way of coping with the self-loathing brought on by those beliefs.
In the "International Super Spy" special episode of The Backyardigans, Uniqua's character, the Lady in Pink, sings about how evil she is by listing all her horrible traits, including the fact that she doesn't "even like pie."
Beast Wars' Blackarachnia spends a lot of her first season or so repeatedly telling the heroes that she's evil, bad, evil, not to be trusted, and evil, occasionally even resorting to actual action to get her point across to particularly irritating non-believers.
Silverbolt: Blackarachnia, I want you to return with me, to the Maximals. Blackarachnia: Get a clue, you canine cretin! I'm a Predacon! I'm evil! I'll shoot you— Silverbolt: No. My heart tell me that you will not. Blackarachnia: Oh yeah? * shoots him in the leg* Silverbolt: * shocked* You...SHOT me! Blackarachnia: No duh, Dog-Boy! I'm evil!! Now do you believe me? Silverbolt: And yet...you ensured the wound would not be mortal. Your inner Maximal goodness— Blackarachnia: SHUT UP, SHUT UP, SHUT UUUUUUUUPPP!!!
You can't say evil in that show without mentioning Tarantulas, whose outright villainy and treacherous attitude was something Megatron considered to be a viable asset.
In Beast Machines, Thrust and Jetstorm take on this role, while Megatron ironically believes he is doing good:
Thrust: Nothin' noble 'bout us, boy! Jetstorm: But savage? That we can do!
Parodied by The Boondocks. BET (Black Entertainment Television) actually stands for Black Evil Television, and their corporate headquarters looks like something out of a James Bond movie.
"It's not good enough that our shows are bad, they have to be EVIL as well!"
While, contrary to popular belief, Captain Planet's villains generally did have some kind of discernible motive (usually raw profit at the cost of the environment), causing damage to the planet for its own sake sometimes seemed to take a life of its own and supersede anything else. In particular, villains such as Verminous Skumm, Dr. Blight on a bad day, and the evil spirit Zarm tended toward the "Corruption/Destruction for its own sake" end of the scale since they were just completely evil and insane.
The phrase "Captain Planet villain" has become something of a shorthand on the Internet for a villain with poorly thought-out motivations — or a Corrupt Corporate Executive in Real Life whose unpopular decisions are of dubious benefit to them or their company — but on the next level you have the "Care Bears villain". With the Care Bears' entire schtick being spreading love and kindness and happiness and just plain pure goodness, naturally their antagonists tended towards people who, for whatever reason, wanted nothing more than to do the exact opposite.
On a character basis, Father calls himself the second most evil adult, then refering to his father as the 'World's Most Ultimate Evil' before reawakening him. Grandfather goes on to refer to himself as pure evil.
A number of Danny Phantom villains refer to themselves as such (most notably Technus). Big Bad Vlad Plasmius initially averted this - for the first two seasons, being called a villain was almost a Berserk Button for him - but after Villain Decay began to set in he started acting more like a conventional card-carrying baddie.
Eek! The Cat: Thugo, the leader of the skeletal Thugasaurs, prides himself on being an exemplary villain. He's constantly hatching up evil schemes to destroy the Dinosaurs, dresses in a black hood, and does the Evil Laugh every other episode.
It's not fair. Somewhere out there, there's a more evil Bender than me. I DO MY BEST, DAMMIT!
In "A Head In The Polls", Richard Nixon's Head tells Leela that if elected he's going to sell all of Earth's children's organs to zoos for meat, apparently for no reason other than to prove his own evilness.
The Robot Devil. Unsurprising, since he's programmed to act like Satan.
Downplayed: Farnsworth doesn't exactly think of himself as evil, but he readily admits to being insane and amoral.
Played with in the Gargoyles "Coyote" by David Xanatos. While attempting to capture the titled Native American spirit, Xanatos puts the captured Goliath and Angela in a Death Trap that will also destroy a native sand carving dedicated to the same. When Goliath points out Angela has no part in their rivalry, Xanatos points out that, while he actually has no malice towards Goliath or the gargoyles, the trap has to be genuine or else Coyote won't show.
Xanatos: It's my first real stab at cliched villainy. How am I doing?''
Green Eggs and Ham: Parodied. The BADGUYS's business card is literally just the word "BADGUYS"... on the front, but it turns out to be a Nonindicative Name once one actually flips the card around. It's actually an acronym for Bureau of Animal Defense, Glurfsberg, Upper Yipville Section. They're Good All Along.
After He-Man explains that Christmas makes people "feel good," Skeletor responds, "I don't want to feel good! I want to feel evil!"
Invader Zim: The title character. Despite not actually being evil, he is more of a Big Bad Wannabe.
"With this, I can bring The Tallest here to witness my ingeeeeeenious eeeeeeeevil! AAAAAAHAHAHAHAHA! I said evil!
Jackie Chan Adventures had one episode with a literal Card-Carrying Villain. Complete with bad puns ("We have the upper hand," etc., etc.).
Jade also references this trope when referring to the Dark Hand as "Card Carrying Members of the Forces of Darkness."
Lucius on Jimmy Two-Shoes, along with all the rest of his family (except Beezy) are basically different generations of Satan and the owners of Misery Inc., a Mega-Corp that's sole purpose is to make the citizens of Miseryville, well, miserable.
Heloise could count too, being the one who creates all the misery-causing products for Lucius' company ("I aim to displease"). She even gets flattered whenever Jimmy and Beezy call her out on doing something horrible.
General (under possession from the spirits): How would one contact this "Just-Us League?" Sergeant: I don't know, sir. Wear a gaudy costume and threaten a bunch of people? General: Thank you Sergeant, you've been quite a help.
Kim Possible's Rogues Gallery not only self-identify as evil without exception (there are no Well Intentioned Extremists in this world), but most try very hard to prove it. Shego, in particular, is a good example. She's clearly in it as Drakken's Dragon for the money, but also tries to beef up her evil credibility on her own time; maybe because she used to be a superhero. One time, she was even manipulated into helping Kim Possible herself, when the heroine threatened to tell the world that Shego used to be a good guy.
Evil is a whole lifestyle in Kim Possible, with its own magazines (Shego reads Villainess while not listening to Drakken's Evil Plans), supervillain conventions and trade shows, and a corporation that supplies equipment and henchmen ("HenchCo"). Though a Disney-produced show, they aren't above taking potshots at the corporate lifestyle and how nicely it dovetails with being a villain.
It even has its own TV show: Evil Eye for the Bad Guy.
The villain culture has a whole set of traditions, to which the bad guys generally adhere, even when they clearly give the heroes a chance to escape or turn the tables.
The Really Rottens from Laff-A-Lympics revel in being underhanded finks and can't resist cheating to win. In "France and Australia", Daisy Mayhem is even personally offended when Mildew Wolf congratulates her team for winning without cheating.
Other villains in the series tend to also be quite open with the fact that they're evil, there's even a company making devices just for super villains and a special driving test for them. Heck, they even have their own evil version of Santa Claus who rewards them for being evil!
A bit of a plot point in the Legion of Super-Heroes episode "Phantoms". Phantom Zone escapee Drax hears the voices of his still-imprisoned parents in his head, constantly reminding him that he's evil and always will be. Supervillains really do make Abusive Parents.
In the Grand Finale, despite never having self-identified as evil before (quite the opposite, in fact), the still-alive villain says to...no one in particular, "Evil does not die. It evolves," in an ill-fated Sequel Hook.
Princess Luna in My Little Pony: Friendship Is Magic may have originally been motivated by jealousy and loneliness, but by the time she returns as Nightmare Moon in the season one opener, she has reached full-on Evil Is Hammy mode — complete with Evil Laugh and a vocal performance clearly inspired by Maleficent — and has nothing on her mind but pure, ironic revenge against her sister and the subjects who once ignored her. All the other antagonists who were ultimately reformed were won over by kindness, but not Nightmare; she had to take a direct blast from a rainbow summoned by the same magical artifacts that had sealed her in the moon 1000 years ago.
OK K.O.! Let's Be Heroes: Practically every villain describes themselves as such. The villains can even have their own collectible "pow cards" showing off their stats, distinguished from the heroes by their negative power levels. The main villain, Lord Boxman owns his own Killer Robot factory and has other self-declared villains as regular costumers and investors. Galgarion seems to be an exception. Despite having Obviously Evil aesthetics and a villain Pow Card, when his enemy Hero told him that he forgot why they are fighting, he says that he thought that they're long lost brothers and Hero is the evil one. Some of the characters aligned as heroes, such as Elodie, Wally the White, and Foxtail, have done moral questionable things or have purely selfish motivations. Apparently, being a self-declared villain is the only thing that guarantees a negative Hero Level.
Harmless Villain Dr. Heinz Doofenshmirtz. He calls himself evil and has a company called "Doofenshmirtz Evil Incorporated", complete with jingle. In several episodes, he has a Villain Song where he declares how evil he is. It comes to the point he'd erase the media just to prevent his fellow villains from finding out he (accidentally) saved a kitty. In the Christmas Special, he is depressed because he can't ruin Christmas with proper villainous zeal, since he doesn't actually hate the holiday. The finale ultimately averts this for Doofenshmirtz when his daughter, Vanessa, points out that he's actually a nice guy who pretends to be evil out of obligation to his backstory, and that it hasn't made him happy. Further averted in Milo Murphy's Law, when it's revealed that Heinz Doofenshmirtz was actually the "Professor Time" who invented the time travel system used by the Time Agents.
In the episode "The Temple of Juatchadoon," Isabella parodies this. When accused of being a dirty double crosser, she produces yet another card from inside her outfit. "Isabella Garcia-Shapiro, Dirty Double-Crosser."
The Powerpuff Girls is full of these guys. Mojo Jojo is the most notable. Subverted when he actually manages to take over the world, and turns out to be a benevolent ruler who makes the world a much nicer place to live. Double subverted when he quickly realizes that Victory Is Boring, so he gives up his power and returns to causing mayhem purely for the fun of it.
The Ren & Stimpy Show had a "professional bully," Victor, who showed Stimpy his Bully Union membership card.
In Rocky and Bullwinkle, Boris Badenov and Natasha Fatale are this trope, as is their nation of Pottsylvania. When Boris swears, he uses words like 'decency', 'honor', and 'joy'. He is occasionally awarded the "Order of the Double-Cross" by Fearless Leader, and when Natasha calls him a "sneaky, fiendish, rotten, no-good snake in the grass", she means it as a compliment. For a taste of Pottsylvanian culture, listen to their National Anthem;
"Hail, Pottsylvania, Hail to the Black and Blue! Hail, Pottsylvania, sneaky and fiendish through and through! Down with the good guys, up with the boss, Under the sign of the Triple-Cross! Hail Pottsylvania, Hail, Hail, Hail!"
In the movie, when Natasha starts musing about what a wonderful life they could have together if they could only stop moose and squirrel, she mentions about how they could have children that they raise to be "little monsters". This is mentioned in the same breath as them living a peaceful life in a house by the sea.
She-Ra and the Princesses of Power: Subverted for the most of the cast, who have complex reasons or some kind of justification for their actions. Played straight with Double Trouble, though while they never call themself 'evil', they meddle in the war, causing massive destruction across Etheria and loving every minute of it, never making an attempt to apologize or explain themself. They have no personal stake in the war either, participating only because they wanted to get paid and cause chaos. Not even Horde Prime's invasion could make them regret anything.
Double Trouble: Remember, this is supposed to be fun.
Catra: This is war.
Double Trouble: No reason it can't be both.
Mr. Burns from The Simpsons sometimes introduces himself with the Imperial March music from Star Wars. He also once made an offhanded reference to Yale's Department of Applied Evil.
Moe the bartender had literal villain business cards printed up.
Mr. Black in "Kamp Krusty" holds a banquet in honor of his and the bullies' mistreatment of the attending kids, making a toast to evil.
The Republican Party as a whole in the Simpsons universe. The Springfield chapter headquarters is a freaking castle that wouldn't look out of place in a Hammer Horror movie and every member within has had some pretty strong moments of corruption at one point of the series or another (and Mr. Burns is its oldest member).
Gargamel of The Smurfs is seen singing about his evilness in a couple episodes such as "Sassette". In adition, in "Gargamel the Generous" when he was pretending to be nice, he stated that he hated the feeling of being nice. In "Heavingly Smurfs", when the Smurfs trick him into thinking he has to be nice to them to avoid going to Hell, after Gargamel thinks he has returned from the afterlife, he says "Thank bad, I mean good". In the Smurfs Christmas special, he says that he hates Christmas because of the happiness people feel from it.
In SpacePOP, Evil Empress Geela is proud of her evilness and hates anything good.
You can tell that Doc Ock has fully become one by the mug he drinks out of that has "Evil Genius" written on it.
This trope is played to (arguably) humorous effect with Darth Maul in Star Wars: The Clone Wars, when Maul inquires whether there would be any jailed former political figures suitable to replace Pre Vizsla as a puppet prime minister of Mandalore.
King Koopa, Bowser's animated counterpart in all three of the animated series, plus his seven Koopalings in the latter two series. The Koopalings are an interesting example because each has his own branch of nastiness and are proud of it specifically (like Cheatsy being proud of being underhanded).
Really, just about every villain in the Super Mario cartoons counts as this. A prominent example: Wizardheimer in the Super Mario World episode "Ghosts 'R' Us." When asked why he does what he does, his answer is:
Wizardheimer: Because I'm an evil Koopa Wizard! I don't need a reason to be mean and nasty. It's my nature!
Trigon is a card-carrying member of this trope, but that's understandable, given that he's an eight-story tall red demon.
Early on, the writers couldn't even come up with a goal for main villain Slade. Few villains even got origin stories, so most seemed to just be causing havoc for the fun of it. Downplayed with Slade: he probably knows that he's in the wrong, but he doesn't care. Of course, that Creepy Monotone can make it hard to figure out exactly what he feels.
Better examples are Brother Blood, who teaches a supervillain school that includes courses on doomsday threats and "Theory of Mayhem", and the Brain, who actually puts the word "evil" in his organization's name!
Possibly the funniest example of this is Control Freak: A fat expy of an overly-obsessed fan-boy whose only motivation is being seen as the Titan's nemesis by the Titans themselves! He's rarely a threat because of this, but because of his reality-warping powers he'd probably be their most dangerous foe if he just got serious and had a firm goal in mind rather than just getting the Titan's attention.
In the Looney Tunes cartoon "Water, Water, Every Hare", Bugs Bunny finds himself in the castle of an Evil Scientist. The guy's castle even has a lit sign with the words "Evil Scientist" out front, and after his monster Rudolph (called Gossamer in other shorts) fails to catch Bugs, he grumbles, "never send a monster to do the work of an evil scientist."
Mumm-Ra from Thunder Cats is a particularly notable example. He gloats about his evil nature so much that he puts other villains of this kind to shame. His counterpart from the 2011 reboot counts as a Card-Carrying Villain as well. Albeit less overtly than in the original series.
Max from Total Drama Pahkitew Island is a self-professed Evil Genius. He's a parody of the show's need to have a villainous contestant every season (Heather, Courtney, Alejandro, Scott and Mal), but lacks the Manipulative Bastard part of the role, which was assigned to Scarlett.
Tromaville's corrupt mayor Max Grody from Toxic Crusaders would frequently make boastful claims about how despicable he was. For instance, he happily admits that he kicked his own mother out of her home in "Club Fred".
Captain Zero: You're a team! The best, the better-looking, more powerful, and, dare I say? More devious! Zip: What is devious? Captain Zero: What's devious is what's necessary to make an honest living in these days of corruption and bad business ethics! Zip: ...Oh.
The evil gnomes in the Van Beuren Studios short "The Sunshine Makers", who openly call themselves nasty, mean and sad, and hate anything sunny or happy.
The Venture Bros.: Every SINGLE villain in the series is a card-carrying villain belonging to the aptly-named Guild of Calamitous Intent. Which, ironically, is depicted as having an important honor code and being an accepted facet of society. The protagonist, however, is a complete and total asshole.
Black Hat in Villainous. Half the shorts have him attempting to market some kind of evil gadget to his fellow villains, while a lot of the remainder have him act vaguely dickish towards the other characters just because he can.
In Wacky Races and its various incarnations, Dick Dastardly is a proud and unfettered cheater. His car, the Mean Machine, is by far the fastest and most technologically advanced vehicle in the race and he could easily win far and square... but he's the villain and villains cheat so he often uses the time he's gained from his vast lead ahead of the other races to lay traps. One episode had him stop feet from the finish line and actually let the others win because he'd gotten that far without cheating and wouldn't let himself win fair and square, and the unaired pilot of Wacky Races Forever has him going so far as to outright reject the possibility of winning fairly rather than cheating by telling Muttley that, as villains, they simply have to win by foul play.
Every single bad guy in the galaxy is this; "villain" is treated as a glamorous career option like "rock star." By Season 2, there's even a "Galactic Villain Leaderboard" which measures rankings based on the amount of planets conquered or destroyed.
Xiaolin Showdown has both examples of this: most of the Big Bads are Black Cloaks and Jack Spicer desperately wants to join their club and get respect. One Big Bad comments that Jack tries so hard to be evil because of his insecurities. Jack refers to himself several times as an "Evil Boy Genius". He also has club jackets with his face and "evil" on it and, of course, he has an evil trademark laugh.He didn't just trademark his laugh, he stated he was adding evil and other such words to his devices to "create a brand".
Averted for The Light in Young Justice, the only time they ever do stuff like this is using it as a distraction to their real plan. They also have a benign name instead of the Legion of Doom or the Secret Society of Super Villains.
PJ Masks: All night-time villains have this to a certain degree, but the Wolfy Kids take the cake. They repeatedly ackknowledge that they are bad wolves, and what they do is evil.
