Vegetarian Vampire/Playing With

Basic Trope: A vampire with an aversion to drinking human blood, usually on moral grounds.
 * Played Straight: Vlad does not bite humans. He instead prefers to drink animal blood.
 * Exaggerated: Vlad does not drink any kind of blood at all.
 * Inverted: Vlad drinks only human blood, direct from the source.
 * Vlad isn't a vampire, he drinks human blood For the Evulz
 * Justified: Vlad believes that drinking blood from humans is wrong.
 * Vlad is an "energy vampire"; he survives on spiritual energy, not blood.
 * Vlad was 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 depends on the setting.)
 * Vlad is supposed to subsist on something other than blood (such as coffee) to get the energy he needs.
 * Vlad is a Friendly Neighborhood Vampire
 * 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.
 * Deconstructed:
 * Reconstructed:
 * 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, Vlad seduces the cow he bites into...and is seen with it later.
 * Lampshaded: "Oh, no. Biting humans is wrong. I only bite cows."
 * "What? It's just cranberry juice!"
 * Averted: Vlad is not a vampire.
 * Vlad is a vampire, but primarily (or exclusively) drinks human blood.
 * Enforced: Our Vampires Are Different, Friendly Neighborhood Vampire, Dark Is Not Evil
 * Invoked: Vlad is "turned", but does not feel comfortable biting humans, especially without their consent.
 * Defied: Vlad's Blood Lust is overwhelming, and he bites the first human he sees.
 * Discussed:
 * Conversed:
 * Played For Laughs: Vlad joins a group of vampires called "VETH" (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?
