Dracula

Strach poses as Count Dracula. (COMIC: Jenny Everywhere in the House of Terror)

Count Dracula was a notorious figure of horror, an arrogant, powerful vampire.

Strach attempted to pose as Dracula to Jenny Everywhere when she claimed to have recognised him, behind a different disguise, as a “lord of darkness”. However, Jenny was not taken in by the glamour and forced Strach to assume other shapes before finally revealing himself. (COMIC: Jenny Everywhere in the House of Terror)

In at least one universe, there existed a Cardinal Dracula, who was simultaneously that world's Dracula and its Cardinal Richelieu. He was also a Mind Flayer rather than a mere vampire. (PROSE: Preludes and Distractions)
