Vampire

"I want to suck your blood!"

• typical vampire saying

Blood-sucking undead creatures of the night: although originally conceived as horrible zombie-like thralls in European folklore they have become popularised as much more intelligent, human-like beings that are labelled "living dead" so as to enhance the idea of them being more powerful and smart than the usual undead.

Alternatively a vampire can be any kind of creature that is said to feast regularly on blood or other sustance (such as energy, life-force etc) - though beings that steal life-force may be closer to a Collector Of Souls archetype.
