"My face is an index to my mind
"Full of venom, spleen, and gall"
Sir Ruthven Murgatroyd, Ruddigore
"By now I thought you would've realized I'm the bad guy."
Rachel Bitterman, It's a Very Merry Muppet Christmas Movie
"Colonel Haken has a hook for a hand, a scar on his face, an evilly waxed moustache, and wears a monocle. Oh, and he's a Nazi. Really, what more needs to be said? (Hint: He's a bad guy.)"
"[It's] Amazing how such an evil-looking alien turned out to be evil all along."
"Am lonely. Saruman maybe not so unattractive after all. If only were not for giantly flaring nostrils and huge clawlike fingernails... Okay you'd think I might have figured out he was evil before."
"...Okay, no, he's totally a bad guy. Is that a spoiler? I don't think it's a spoiler. Look at that thing. It probably ate a puppy for breakfast right before it burned down an orphanage and talked loudly on a cell phone at a restaurant."
"In addition to the Starfleet personnel, there are also a few guys here who just scream out "Guest Alien Villains of the Week". They're gray-faced, with sinister looking hoods, and faces that look like the result of too many Botox injections. Darth Maul was less obviously a villain than these guys."
"Darth (Maul) wears black boots, a black cloak, a black shirt, has a red lightsaber, wears red and black face paint, and has horns. He is EVIL."
"Wha... aw, damn it. And he looked like such a trustworthy guy!"
"Are there really a lot of people named Dr. Hell? You could not have a name that shouted "Hey look, I'm evil" louder if you tried."
TV Reporter: His victims have included businessmen, Asian immigrants, the elderly, and in one case, a sexually-assaulted child.
Film Brain: Oh, real tasteful! Just in case you didn't get he was the bad guy!
"Did anyone else notice the lightning?"
— Timmy Turner when he first met Vicky, The Fairly Oddparents: Abra-Catastrophe!
"What did you call me, fairy? Nobody calls me a loser. NOBODY! Behold... Fists of iron... Eyes of fire... Wit as sharp as a sword. Hahahah... not to mention pretty, too!"
— Lord Darkar describing himself, Winx Club
Icy: Did you see that?
Stormy: Yeah. Ugly.
Darcy: And to think we were crushing on him!
Stormy: I know. First, Darkar, and now Baltor!
Icy: I really have to admit, we have no taste in guys.
"Okay, yes. He dragged a Great Old One up in chains from Hell itself to serve him! But that doesn't make him evil! Wh-wh-why would you think that?"
Finn: I can't shake this weird feeling about Ricardio. I think he's... a villain!
Jake: Why? Is it because his face is so foldy and dramatic?
— Adventure Time, "Ricardio the Heart Guy"
"Walking stick, spiky hair, twirly mustache - he's a villain alright."
— Hreidmar's examine text in Runescape
"This guy is giving off a murderous vibe! Even getting close to him makes my skin crawl..."
"Christ, movie, we get it! He's a bad guy! We spotted that before the massive racist tirade he just did! He couldn't be more transparent if he started twirling his moustache!"
— Film Brain, Bad Movie Beatdown on The Condemned
"This guy has the word VILLAIN written all over him!"
— Etna about Vulcanus in Makai Senki Disgaea
"You know... She said evil didn't look like anything, or that it looked like a lot of things... But I think it looks like you."
— Shadowchild', Digger
"Reapers may look evil and crazy, but there's a good reason for that. They ARE evil and crazy."
— Palutena Kid Icarus: Uprising
"Woah, that's a bad guy, that's a really bad guy! Did you see his face? His head looks like one of the Easter Island heads!"
—Max, Get Smart
"Tonight, the part of 'Al' will be played by a tall, dark, and sinister ugly man."
—The Genie, Aladdin
"He did that? This is the first I've heard of it. I actually don't know anything about this kid, I just ... I mean, look at him. He sucks. And he's objectively evil-looking. If I had to design someone to be the embodiment of slimy evil, he's the guy I'd design. He looks like if vanity, smugness and blond hair had a baby. He's what entitled douchebags bow and pray to at dawn. At all times he looks like he just can't wait to go home and smell his own poop. Slimy, slimy little twerp, I hate him."
I'm not so sure why everyone thinks allying with this newcomer is such a great idea, though. Calling your faction "The Shadow Runners" and having a big skull for an emblem isn't exactly reassuring. I mean, come on... were any of the Autobots honestly surprised when the Decepticons betrayed them?
Lets see; mad scientist, mustache... nope, I'm definitely the badguy.
—Dorkly, Robotnik Finally Wins
I come from the darkness of the pit!
To the slaughter!
Tremble before me!
I bring darkness!
I go to destroy!
Don't waste my time.
What is your feeble request?
You fail to amuse me.
Taylor: I'm a good guy.
"Come on, he's dressed in all black, this guy is about as subtle as a fork in your face."
"This guy looks like the devil and his name is based on the word sinister. This dude was destined to be evil."
"Look at the spikes he's wearing! He's gotta be evil!"
