A three way vinn-diagram with pirates, vampires, and Princes in the three main circles. At the intersection of pirates and vampires is "classic go-to villains". Vampires and Princes share "living in castles". Princes and pirates both have "stealing from peasants". The shared trait of all three is "wearing these shirts" with a picture of a fancy white shirt with big ruffles on the neck and sleeves.
Gentlefolk, I give you Stede Bonnet, Gentleman Pirate and apparent vampire.
