Existem vampiros em Star Wars?

Sim. Eles são as espécies chamadas Anzati.

Um bom artigo sobre eles pode ser encontrado aqui:

The Anzati are an alien race in the Star Wars universe probably inspired by vampires. These mysterious aliens have many characteristics in common with vampires: they hunger for the life force of other beings, subdue their victims with mind control, live for millennia, are incredibly fast and strong, and have no pulse.

Curiosamente, eles parecem ser até mesmo G-canon (bem ... pode ser ... vou fazer isso como uma questão à parte)!

The first Anzati in Star Wars canon was Dannik Jerriko, a bounty hunter who appeared in the Cantina Scene in Episode IV: A New Hope. His backstory is explored in the short story "Soup's On: The Pipe Smoker's Tale," by Jennifer Roberson, which appears in the short story collection Tales from the Mos Eisley Cantina (Bantam Spectra, 1995).

Vampiros (de descrições variadas) aparecem em todo o cânone de Guerra nas Estrelas, mas NÃO no filme canônico, exceto através de adições da UE.

Vários tipos incluem:

Vampiros de Energia

Estes são encontrados no cânone Guerra nas Estrelas: Guerras Clônicas ;

Energy vampires were creatures who drained the life forces of others, by way of biting their enemies in order to feed. They had retractable serrated claws, elongated teeth, accelerated senses, and enhanced strength and speed. They were able to drain beings of energy to feed as well as turning these beings into mindless zombies;

Anzati

Estes são inicialmente mencionados em Star Wars: TOR

The Anzati (singular: Anzat) were a dangerous and mysterious Force-sensitive near-Human species with two tentacle-like proboscises that curled out and extended from their cheeks, with which the Anzati were able to feed upon the brains of their prey. With the tentacles retracted into seams along each side of their nose, Anzati were indistinguishable from any other humanoid species in the galaxy.

Force Vampire

Este indivíduo é mencionado no livro de origem de Star Wars: The Roleplaying Game

The Force Vampire, formerly known as Jedi Knight Tel Angor, was the result of the Order of the Silver Jedi's experiments into creating a living symbol of the light side of the Force. Unfortunately for the Order, the experiments had the exact opposite effect; rather than Angor drawing on the Force to bolster his abilities, the dark side corrupted him completely, turning him into a hideous creature that fed on the Force itself, and indeed needed it to survive. Angor ceased to be himself, and became the Force Vampire.
