Four vampires from the TV series 'Buffy the Vampire Slayer', who lived and hunted together in the late 1800s. Individually, they were: Darla, Angelus, Drusilla and William (later known as 'Spike').
After Angelus was cursed with a soul, they disbanded and went their separate ways; though they all ended up in Sunnydale, CA at some point between 1997-2003.
'So Spike, Angel, Dru and Darla...are together again?'
'Looks like. Fanged Four want another go at the glory days.'
