Usually, villains have a personality or manner that underscores how evil they are. They may kick puppies for giggles, be particularly insensitive and/or fanatically obsessed with their cause, or might just be too unknowable and/or eldritch to be anything but evil.
Then there are villains who are Affably Evil. There is absolutely nothing separating them from being normal, polite people except for the fact that they want to Take Over the World or use human souls to power their Artifact of Doom. They're not the Stepford Smiler or the Bitch in Sheep's Clothing— their affability is a genuine part of their personality, not a mask. And this is what ultimately differentiates them those tropes and Faux Affably Evil. If they have underlings, expect them to be a Benevolent Boss. In one way, they're the opposite of an Anti-Hero. They may Pet the Dog on occasion, but won't hesitate to kick it with steel-toed boots the next second if it helps them accomplish their Evil Plan. They may well be a Villain with Good Publicity because, after all, being evil doesn't mean you have to be anti-social.
If this trope gets exaggerated, this villain will invite the hero out to tea, offer them a favorite dish, talk friendly, try to appeal to the hero's better nature, and convince the heroes that the villain's plan isn't worth getting involved in or is even worth joining. Of course, if the hero still won't change their mind, the villain will remind them that they are, after all, still a villain. It may or may not involve a Death Trap, depending on how nice the villain really is when crossed. Of course, inviting the hero's mom out to tea might send a stronger message. The friendliness of said villains can serve to humanize these guys. In situations with Evil vs. Evil, they are often A Lighter Shade of Black in this conflict.
Usually a Wicked Cultured, charismatic Magnificent Bastard. They are sometimes comedic or a Well-Intentioned Extremist who really believes that they are right. More often than not, they are a form of Anti-Villain because a straight villain wouldn't easily be so genuinely good-natured. Evil Has a Bad Sense of Humor is not true for them, and their affability even makes them easy to "compliment" with an Insult Backfire. Captives of an affably evil villain won't be kept in dungeons, but in a Gilded Cage. Even an outright psychopath can come off as this if charismatic and funny enough. In fact legitimately insane characters can at times balance this with Faux Affably Evil more easily than sane ones, since the contrast is explained by their mental instability.
In the event an Affably Evil villain does undergo a Villainous Breakdown, the very traits that make them so pleasant often serve to make their breakdown extremely creepy or outright scary. A kind, friendly man suddenly going into a psychotic rage is made all the more scary by the simple fact that he was previously so nice and kind. If they keep their inviting personality while going Ax-Crazy, they may cross into Faux Affably Evil territory with only skin-deep manners, which is a much more frequent behaviour than a truly kind criminal.
- Adaptational Nice Guy: A villain can become Affably Evil in an adaptation of a work where they were depicted as being a jerk.
- Ambiguously Evil: If someone is such a nice person, can they really be a villain? (Yes.)
- Anti-Villain: A villainous character that is in a moral grey area, sometimes overlaps with this trope.
- Beware the Nice Ones: Basically the Evil Counterpart of this trope.
- Churchgoing Villain: A villain who doesn't see any reason being a criminal should stop them from being devoutly religious (unless they're The Fundamentalist or they go to the Church of Happyology, in which case, they're Faux).

- Pragmatic Villainy: A villain who may be affable for their own reasons. Some definitely overlap with this trope.
- Punch-Clock Villain: The villain may not be exactly evil, depending on what their villainous duties are — they simply have a job to do, and their employer just happens to be evil.

- Too Funny to Be Evil: The villain's good sense of humor makes people think they couldn't possibly be a bad guy.

- Bitch in Sheep's Clothing: The character hides a more sinister side behind a nice facade — unlike them, Affably Evil characters are genuinely nice.
- Complete Monster: The most heinous characters played seriously with no redeeming or altruistic qualities. They are 0% nice (though may be Faux Affably Evil).
- Enemy Mine: The villain realizes they need to cooperate with their enemy to achieve a common goal. That doesn't mean they have to be nice about it.
- Faux Affably Evil: A villain who adopts an affable demeanor that isn't genuine, basically mocking Affably Evil. They'll chat pleasantly with their victims while engaging in Cold-Blooded Torture, or hum cheerfully to themselves while setting an orphanage on fire. Unlike Affably Evil characters, they're genuinely mean, and often do things For the Evulz, but it might not be obvious just by talking to them.
- Good Is Not Nice: The opposite of this trope. The guy's a hero, but is rude, crude, and sometimes, sometimes even outright cruel.
- Good Is Not Soft: A hero is genuinely nice but ruthless to their enemies. Essentially the good version of this trope which could be interpreted as "(very) affably Anti Heroic".
- Harmless Villain: When the villain is not necessarily affable, just no one to be scared of.
- Laughably Evil: The villain derives humor from their crimes. There's nothing necessarily nice about them, and usually just serves to showcase that Evil Has a Bad Sense of Humor.
- Lovable Traitor: It's obvious you can't trust them, but they're still all right to hang out with.

- Your Approval Fills Me with Shame: The hero is dismayed to be seen as the kind of person the villain would be nice to.
Good Is Not Nice is the Inverted Trope, and such good guys are particularly good at giving the Affably Evil a proverbial punch in the nose. When both Good Is Not Nice and Affably Evil are used, you may end up with Polite Villains, Rude Heroes. I'm Not Hungry is often dealing with this villain. A villain will sometimes engage in Too Funny to Be Evil to achieve this effect. No, Mr. Bond, I Expect You to Dine is a subtrope in many instances.

- The Adventure Zone: Balance: John, the source and avatar of the Hunger, which consumes entire realities, is pleasant and polite, even playing chess with Merle, and enjoying their conversations. He also kills Merle repeatedly, and his goal is to eat all of reality so he can undo the laws of the universe.
- In Sequinox, several stars come off like this. Part of it comes off as them trying to awkwardly work human concepts into their conversations despite not understanding how any of them work. Antares is happy that she gets to talk to people instead of just destroying the planet right off the bat. Sargas is very polite when he tells the students of Vertumnus to turn over the Sequinox girls or else he'll kill everyone.
- Old Harry's Game:
- Satan zigzags this trope and Faux Affably Evil. To most people, he's faux affably evil, often utilizing Exact Words or even outright lying to make them think he's about to give them what they want right before torturing them. To other supernatural beings, and the handful of humans he genuinely respects, he's this; he'll still torture them if they become annoying, but when he's not doing so he's fairly friendly and can sometimes even act as a caring presence.
- Thomas is introduced as a Faux Affably Evil Corrupt Corporate Executive. However, over the course of the series, the Prof and Scumspawn manage to reform him somewhat; he's still evil, but he's closer to this trope.
- Gary, Satan's initial top demon, is quite polite despite his love of cruelty.
- God is respectful of those he speaks to, generally willing to listen to reason (provided you don't question whether there are other gods), wishes his angels were more able to lighten up and have a laugh, and frequently sends people to Hell for little to no reason.
