The Sonic SatAM version of him as well, though to a lesser extent...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.
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.
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.
In Codename: Kids Next Door, villains eventually evolve into this, having 'supervillain meetings' and a supermarket for villains only. This even goes so far as a 'Villain's Choice Award'...on public television!
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.
Same thing goes for the villains in El Tigre: The Adventures of Manny Rivera. They even have a villain quarterly magazine.
It's not fair. Somewhere out there, there's a more evil Bender than me. I DO MY BEST, DAMN IT!
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.
G.I. Joe, with the vastly over-the-top COBRA Commander.
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.
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.
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.
Aku, the Big Bad of Samurai Jack, identifies himself as "Master of Masters, The Deliverer of Darkness, and the Shogun of Sorrow." His name even means evil in Japanese.
Burns 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.
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.
King Koopa, Bowser's animated counterpart in all three of the animated Super Mario Bros. 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:
"Because I'm an evil Koopa Wizard! I don't need a reason to be mean and nasty. It's my nature!"
Krang also has been known to say this more than once and being even more evil or cruel than Shredder, OR towards Shredder when Shredder's plans sometimes backfire on him big time.
In the 2012 TMNT show, Karai casually agrees with Raph's statement that she is "bad news."
Several in Teen Titans. 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. Trigon was a card carrying member of this trope, but that's understandable, given that he's an eight-story tall red demon.
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 who's 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 fails to catch Bugs, he grumbles, "never send a monster to do the work of an evil scientist."
Mumm-Ra from ThunderCats 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".
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.
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.
