Playing With / Affably Evil

Basic Trope: The villain is still very much evil, but is a nice ordinary person besides their villainous traits.
  • Straight: The guy looking to dominate the world is actually a very nice, pleasant person to know, as long as you don't get in his way.
  • Exaggerated:
    • The villain is a frenemy who always wants to hang out with the hero after they're done fighting for the day.
    • The villain is so nice, that he donates blood, plays with young children, and hosts a birthday party for the hero, while preparing to conquer the entire universe.
    • He is indeed a very polite person. This is not an act, it is how he really is. Meanwhile, he plots with Satan to help cause the bloody and torturous eradication of all life.
  • Downplayed:
    • Although the villain isn't always polite, he does Pet the Dog every now and then.
    • The guy isn't overly evil, but he does commit deeds that can make him come across as a villain.
    • The guy isn't kind, per se, but he's not a jerk.
  • Justified:
    • The villain is a little misguided and thinks he's doing the right thing, being an ordinary person, and so this is how he acts.
    • The villain is a Sinister Minister, Evil Chancellor, or other person in a trusted position; even if his niceness is an act, he wouldn't be where he is without it.
    • The villain is the evil twin of a hero that is known to be somewhat of a jerk.
    • The villain is so nice that no one believes he's doing anything villainous, in spite of blatant evidence to the contrary. This was part of his plan all along.
    • Evil is not mean. Mean is not evil. For more information, see Anti-Hero.
    • And he wants to be/already is a Villain with Good Publicity. He decides that the only known way to do so is to be nice.
    • Anti-Villain / Noble Demon
    • The villain believes that just because he is evil doesn't mean that can be used as an excuse to be mean.
    • The villain belives he is a hero and behaves accordingly.
  • Inverted:
  • Subverted:
    • The villain looks like a kind, polite person, but it's all an act.
    • The villain is a complete jerk who happened to be in a good mood that day.
    • A polite guy is shown doing very suspicious things, but it turns out he was good after all. He was just caught at all the wrong moments.
  • Double Subverted:
  • Parodied: The villain is so friendly, he's hardly a threat at all.
  • Zig Zagged:
    • The villain looks like a polite person. It's an act. No it isn't. Wait, yes it is. Can he make up his mind already?
    • Depending on who the villain is dealing with, the affability is either sincere or a cruel façade.
  • Averted: The villain is rude, plain and simple.
  • Enforced:
    • The author is trying to deliver an Aesop that evil comes in all shapes and sizes.
    • "Villains are often mean and nasty. Let's create one who's your average everyday nice guy."
  • Lampshaded:
    • "For a villain, he acts a lot like a normal person."
    • "I may be your enemy, but that doesn't excuse being uncivil."
  • Invoked: The villain tries to become a nicer, more polite person, in order to improve people's opinions of him, even if they do see his goals as "evil".
  • Exploited: After his conversations with the hero, the villain realizes... wait a minute, he knows everything about him now and can use it against him.
  • Defied:
    • "I will not serve dinner for my prisoners! I'm evil, damn it, and I'm going to be a dick!"
    • The villain ponders being nice for a change... and promptly rejects the idea, laughing evilly all the while, in favor of scaring people into submission as usual..
  • Discussed: "All right, time to go confront Overlord Steve! Even though he's evil, I'm sure he won't mind if we drop by and have a chat." "Alice! He's not some friendly movie villain, he's evil."
  • Conversed: "It's weird how, in some movies, the villain is a totally normal guy except for his evil plots. Kinda makes you paranoid, right? Anyone could be evil..."
  • Implied:
    Alice: You escaped! It wasn't too scary, was it?
    Bob: I've definitely had worse captors.
  • Deconstructed:
    • The villain is so affable that he actually wins thanks to his ability to get along with others, while the Anti-Hero drives away any possible allies he may have had.
    • The villainess is an outgoing, charismatic, friendly and socially adept person. This is the reason WHY she became evil; everyone likes her so much that they enable her evil actions. Her victims forgive her too easily, the authorities let her off lightly, none of her peers criticize or censure her, her minions never disobey her orders, any objective reporting of her evil actions gets ignored or dismissed as slander...
  • Reconstructed: ...but only temporarily, as the villainy comes to light before the Point of No Return.
  • Played For Laughs: The villain's cheerful blabbing allows the heroes to make an escape, leaving him talking to himself.
  • Played For Drama: The villain really is a nice person, but he's not the villain because he wants to be.

You're most welcome to head back to Affably Evil any time you like. But I won't take "no" for an answer.
