'''Basic Trope''': A vampire with an aversion to drinking human blood, usually [[DarkIsNotEvil on moral grounds]].
* '''Straight''':Vlad does not bite humans. He instead prefers to drink animal blood.
* '''Exaggerated''': Vlad does not drink ''any'' kind of blood at all.
* '''Downplayed''':
** If any human blood is drank, it's in very small quantities.
** Vlad only drinks blood from murderers or other {{Asshole Victim}}s.
* '''Justified''':
** Vlad believes that drinking blood from humans is wrong.
** Vlad is an "energy vampire"; he survives on spiritual energy, not blood.
** Vlad was [[AfraidOfBlood hemophobic]] in life, and that trait stayed with him when he became a vampire.
** Vlad doesn't like the metallic taste of blood. (He may be a relatively "new" vampire and not used to it.)
** Vlad is concerned for some reason about the possibility of contracting blood-borne illness (such as AIDS or Hepatitis) or parasites (such as malaria or flukes) from biting humans. (Why that should be a concern to an undead creature [[ItMakesSenseInContext depends on the setting]].)
** Vlad is ''supposed'' to subsist on something other than blood (such as [[MustHaveCaffeine coffee]]) to get the energy he needs.
** Vampires in Vlad's setting don't require human blood specifically; animal blood works just as well and is more readily available.
* '''Inverted''':
** Vlad drinks ''only'' human blood, direct from the source.
** Vlad isn't a vampire, he drinks human blood ForTheEvulz
** Vlad is a FriendlyNeighborhoodVampire
* '''Subverted''': Vlad ''will'' drink blood from humans
* '''Double Subverted''':
** But only from medical bags from the local blood bank, not directly from a human.
** Or only if the human in question ''offers'' it to him voluntarily and consensually.
* '''Parodied''':
** Vlad drinks "soy-based blood substitute"
** Vlad drinks only tomato or cranberry juice, or any other red liquid that maybe ''looks'' like blood but isn't.
** Since seduction is usually a key element of vampires, [[BestialityIsDepraved Vlad seduces the cow he bites into...and is seen with it later.]]
** WarmBloodbagsAreEverywhere
* '''Zig Zagged''': Vlad's blood drinking is treated like chronic alcoholism. He means to stay off the human blood, but falls off the wagon every so often.
* '''Averted''':
** Vlad is not a vampire.
** Vlad ''is'' a vampire, but primarily (or exclusively) drinks human blood.
* '''Enforced''': OurVampiresAreDifferent, FriendlyNeighborhoodVampire, DarkIsNotEvil.
* '''Lampshaded''':
** "Oh, no. Biting humans is wrong. I only bite cows."
** "What? It's just cranberry juice!"
* '''Invoked''': Vlad is "turned", but does not feel comfortable biting humans, especially without their consent.
* '''Exploited''': ???
* '''Defied''': Vlad's BloodLust is overwhelming, and he bites the first human he sees.
* '''Discussed''': "What kind of vampire drinks tomatoe juice?" "You'd rather him chomping on you?"
* '''Conversed''': ???
* '''Deconstructed''': Non-human sources of blood aren't as nourishing, and Vlad grows weak. He becomes more and more tempted to bite humans, either because he's at risk of being destroyed or because [[HorrorHunger his thirst]] [[WarmBloodbagsAreEverywhere is becoming more difficult to resist]].
* '''Played For Laughs''': Vlad joins a group of vampires called "VETH" ([[AnimalWrongsGroup Vampires for the Ethical Treatment of Humans]]).
* '''Played For Drama''': Vlad ''craves'' human blood; will his own willpower be enough to keep him off it?
