'''Basic Trope''': A character's bisexuality underscores their villainous and/or [[AxCrazy psychotic]] nature.
* '''Straight''': An evil bisexual is introduced and grosses everyone out because of their proclivities towards both genders.
* '''Exaggerated''':
** The villain parades around in fetish gear the entire film, nearly always with multiple men and women under their arm.
** A villainous ExtremeOmnisexual.
* '''Downplayed''':
** A bisexual character is a bit promiscuous, morbid, and abnormal, but not outright evil.
** The character's willingness to seduce both genders for his goals shows just how ruthless he is.
** The character isn't necessarily a ''villain'', but doesn't seem to have standards, boundaries, or a sense of appropriateness.
** A bisexual character is a villain, but has [[AntiVillain sympathetic and/or redeeming qualities]].
** The villain is AmbiguouslyBi.
* '''Justified''':
** It has already been established in the work that EveryoneIsBi, so that includes the villains as well.
** Alternatively, the villain is a [[TheSociopath sociopathic]], [[TheHedonist hedonistic]], and utterly amoral [[{{Pun}} trisexual]] -- they only care about their pleasure, and not a thing about who or what is being used, willingly or not, in the process.
** [[WhosLaughingNow The reason they are evil is because they were shunned for being bisexual.]]
** The villain is not so much "bisexual" as "[[CombatSadomasochist has an all-consuming paraphilia for stabbing people with knives.]]"
** Everyone on the show is depraved in some way, regardless of their sexuality.
* '''Inverted''':
** The show's bisexuals are actually the least depraved of the whole cast.
** A character's bisexuality underscores their heroic nature.
** NoLoveForTheWicked.
* '''Subverted''':
** The bisexual villain turns out to be GoodAllAlong.
** The villain is TheVamp, and [[PragmaticPansexuality their bisexuality is an act]].
** The "[[NonIndicativeName Depraved Bisexual]]" is actually CampStraight.
* '''Double Subverted''':
** ...but then [[FaceHeelTurn turns on the heroes]] once they've [[MacguffinDeliveryService gotten what they were after]].
** ...or at least that's what (s)he says.
** Upon further consideration, the villain realises they have tastes for both genders...[[SissyVillain while remaining as camp and as evil as ever.]]
* '''Parodied''':
** The bisexual character immediately tries to have sex with anyone who antagonizes them.
** The hero has a [[DatingCatwoman massive crush on the villain,]] and [[NightmareFetishist fantasizes about the terrible things the latter will do to them...]] Much to the villain's consternation, as he plays both teams [[NobleDemon but is otherwise a decent person.]]
* '''Zig Zagged''': A bisexual character [[HeelFaceRevolvingDoor appears to be a hero and a villain at different point]] throughout the story.
* '''Averted''':
** NoBisexuals or most cases of extreme omnisexuality.
** The bisexual villain [[EvenEvilHasStandards doesn't mix their evil with sex]] or [[ChivalrousPervert their sex with evil]], and no parallel is drawn between these two traits.
** The villains sexuality is never addressed.
* '''Enforced''': "This isn't a gay show. If you're using bisexuals, [[DoubleStandard either make them evil if they're men, or make them]] {{Fanservice}} [[GirlOnGirlIsHot fodder if they're female]]".
** The work was written in the age [[ValuesDissonance before such things were considered acceptable.]]
* '''Lampshaded''': "You're bisexual? Why am I not surprised?"
-->'''HeroProtagonist''' ''[[StopBeingStereotypical Wow, talk about setting sexual equality back fifty years.]]''
--> '''DepravedBisexual:''' ''[[BlahBlahBlah Oh, bitch bitch bitch.]]''
* '''Invoked''': The evil empire starts recruiting bisexuals into their armies.
* '''Exploited''': Characters looking for a villain who works behind the scenes consider a character's loud bisexuality a red flag.
* '''Defied''': "Look, what I do in bed is one thing, what I believe is right is another".
* '''Discussed''': "I should have known better... He/She's bisexual after all. Not a good omen in general".
* '''Conversed''': "Why is there so few sympathetic bisexuals on TV?" "Because it's too confusing for many people".
* '''Deconstructed''':
** Because everyone believes bisexuals are evil by nature, when a bisexual character is introduced, they are shunned by everyone.
** [[WhosLaughingNow The reason they are evil is because they were shunned for being bisexual.]]
* '''Reconstructed''': Despite their initial refusal, the good characters eventually give the bisexual character a chance.
