'''Basic Trope''': The king's main advisor is evil and (usually) trying to overthrow him.
* '''Straight''': TheKingdom of Tropia has a good king and an evil GrandVizier. Or, the United States of Trope has a good President and an evil Vice President.
* '''Exaggerated''': The GrandVizier is ObviouslyEvil, refers to himself ''as'' the Evil Grand Vizier, and still has his job.
* '''Downplayed''': The vizier is a neutral or AmbiguouslyEvil figure often at odds with his king, but he usually [[IDidWhatIHadToDo does evil things out of necessity]] and isn't a main antagonist.
* '''Justified''':
** The work is historically based and the period of history actually ''did'' have a coup by a grand vizier.
** Chancellors, Prime Minsters, Grand Advisors and such had more power as actual Heads of Government with little publicity, making these positions suitable spots for TheManBehindTheMan.
* '''Inverted''': The kingdom of Tropia has an evil king. The Grand Vizier is TheGoodChancellor who is secretly funding LaResistance.
* '''Subverted''': The Grand Vizier of Tropia seems to be loyal to his king...
* '''Double Subverted''': ...but he isn't good. The king is also evil and working for him allows the vizier to subjugate and torture the populace ''more'' effectively.
* '''Parodied''': The Vizier is not ''nice'', but he's a [[PokeThePoodle poodle-poking]] HarmlessVillain who's only being bad because he's "supposed to" (like the necromancer in ''Discworld/UnseenAcademicals''). He's not really trying to take over, he's more likely to put salt in the king's coffee than poison, he drives heroes away with cruel practical jokes or [[CutHisHeartOutWithASpoon bizarre threats]] rather than genuine harm, and the court, including the king, see him as their TokenEvilTeammate.
* '''Zig Zagged''':
** The Grand Vizier of Tropia seems to be disloyal, but is later revealed to be loyal and the signs of disloyalty were coincidental. However, the king he is loyal to is bad, so the heroes think they have to get rid of both of them...until the vizier pulls a [[TheStarscream Starscream]] and ''then'' reveals he was GoodAllAlong and overthrew the king in order to PayEvilUntoEvil, becoming a much fairer ruler once he's actually on the throne.
** Or, there are multiple viziers in the story with different alignments.
** Not, however, anything to do with [[WesternAnimation/TheThiefAndTheCobbler this Zig Zag]] who plays the trope straight.
* '''Averted''': The chancellor of Tropia is [[TheGoodChancellor a good man and loyal to his king.]]
* '''Enforced''': The story is written in a strict monarchy where it is forbidden to depict kings as evil, but the author still wants his hero to fight against unjust authority.
* '''Lampshaded''': The Grand Vizier throws a visiting hero into the dungeon for no reason. The hero turns to his cellmate and says "You know, once I saw the Grand Vizier I was sort of expecting this."
* '''Invoked''': The Grand Vizier is a good man, but his populace don't respect him. He assumes Machiavelli was right, and attempts to seem more evil so that they will fear him instead.
* '''Exploited''': The Grand Vizier's assistant is aware of his master's evil nature, and uses that to arrange his own schemes, knowing everyone will just assume the Vizier is behind it.
* '''Defied''': The Grand Vizier knows that people think he's evil, and spends most of his time finding ways to run the kingdom fairly and even [[PetTheDog pet a few dogs]] so that they'll stop thinking that.
* '''Discussed''': Hero Sir Tropesalot is talking with his FiveManBand about how they should be careful in kingdoms because every time they've run into a Grand Vizier he's been evil.
* '''Conversed''': Political candidate Thomas Roper talks to his campaign team about finding a trustworthy running mate and mentions how it would be easier if the real-world evil viziers were as obvious as the fictional ones.
* '''Deconstructed''': The Grand Vizier is originally good and does his best to follow his king's orders, but the people never think ill of their king and, because [[DiscussedTrope this trope exists in the world]] they blame the Vizier for any of the King's mistakes, while not giving him any credit for things the government does ''right''. As a result, he's a very bitter and resentful character.
* '''Reconstructed''': His bitterness leads him to hate the King, [[ThenLetMeBeEvil becoming the evil vizier]] that everyone already thought he was.
