Affably Evil Magnificent Baddies are those who show genuine politeness and friendliness. They contrast with Faux Affably Evils, who merely feign politeness as a means to manipulate others.

Being Affably Evil often helps a baddie's magnificence greatly, as their genuine approachability often makes the other characters in the story like or at least respect them, sometimes even their enemies, and also makes them enjoyable or even likeable to the audience.

Note: Not all MBs have to be Affable or Faux Affable. Some of them are fully open about their antagonism with no friendliness, feigned or genuine, as their magnificence will come from efficiency, quick wit and qualities other than charisma or politeness. Good example of MBs that are neither Affable nor Faux are The Goose and Soundwave from both Animated and Prime.
