Vampyres in Freedom City
As an option, use the Mayfair's scenario I posted. As vampires go, they are not very powerful, so they are less likely to pose a serious threat to a group of superheroes. Even at PL 10 they are better suited to starting characters (but not really a Claremont-based adventure). They are not masterminds, don't really have any criminal intent outside of murder for food, and really are not interested in joining a team. Now they could be uneasy allies in an adventure against Dracula.
As vamps running a local night club or strip joint they would have certainly heard of Dracula's return to Freedom City. Maybe they go to the Heroes in hopes of securing passage out in exchange for knowledge about Dracula and his plans.
What keeps the heroes of Freedom City from shutting them down? Simple, Mayfair's is on the books a legit legal enterprise. Fran and Miriam pay the city thousands in tax revenues not to mention their charitable contributions to homeless shelters (where they can also look for new recruits) and to homes for battered women (nothing nefarious here, Fran feels the need to help). So even city leaders that are not customers see Mayfair's as positive thing. Their underground business has never been proven, so any crimes that happen are hearsay or rumor only.
