ABOUT
Dracula makes his first and only series-appearance in the episode "Buffy vs. Dracula". He is played by Rudolf Martin. Dracula admits to Buffy that he is intrigued and charmed by her legacy as she is of him. He also clarifies the origin of her powers, regardless of his attempt to lure her to evil. Buffy, having "seen his movies", waits after first killing him, noting that he "always comes back".

He is an acquaintance of Anya and Spike, the latter of whom claims he is a sell-out of the vampire world, fond of magic and Hollywood (and that Dracula owes him eleven pounds).

Dracula has special abilities (almost all of which are derived straight out of Bram Stoker's novel Dracula), which are described by Spike as "showy gypsy stuff". These abilities include transforming into a cloud of fog and animals, wolves and bats in particular, and the ability to control minds (put someone under his "thrall"), as he does to Xander in "Buffy vs. Dracula".
