Those be Buffy Vampires.

Or, basically, of the vampires in the CV series since the beginning. Dracula, Olrox, Carmilla and Elizabeth Bartley all come to mind, as far as the older ones are concerned. That's how I like my vampires. Not to mention, each one's "demon form" tends to differ from each other, showing a sort of individualism. I liken it to the vampires in the original Fright Night(hence my avatar). Jerry Dandridge, turning "vamp form" looks nothing like Evil Ed or Amy. Evil Ed's teeth are totally different(almost given rat-like incisors), and Amy gets the "Mouth of the South". In CV, Vampires tend to transform into different demonic forms. Dracula almost always transforms into a large, hulking horned demon(but in CV3, he tranforms into a form that resembles the Estruscan death god Charun). Olrox transform into a giant, reptillian monster. Carmilla transforms into a giant woman(or demon winged woman, as in CotM) riding a giant skull(in LoS, she transforms into a bat-like she-demon). Elizabeth Bartley transforms into a Medusa. I always loved that about the CV vampires.
