10 Best Monsters Of The Week In Buffy The Vampire Slayer

Sunday is the kind of villain fans wished to have seen more of. Maybe some more appearances and a bigger arc would have helped Season Four become a better chapter of the show, but nonetheless it's great she got a chance to shine in at least one episode.

Played by Katharine Towne, Sunday was a vampire who fed on freshmen at the U.C Sunndydale campus. A sarcastic and funny antagonist, she ran her own group of teenage vampires (one of whom was the stereotypical example of high college student) and was a match for the Slayer in their first encounter, beating Buffy hand to hand and cementing herself as a pretty badass in her own right.

Apparently, she was originally conceived as a "Slaypire", a Slayer who is turned into a vampire. This would help explain how she was such a strong fighter, but the idea was unfortunately scrapped. It's safe to say that this would have been one good move, and she would have made a stronger Big Bad than Adam turned out to be.

Plus, could you imagine her interactions with Spike or Harmony? Pure brilliance squandered.
