Throughout the seven seasons of Buffy, there were lots of bad guys and vampires and annoyances, but there were really only seven Big Bads, which *I* classify to be the season long bad guy whose arc culminates in a big demonstration during the season finale.
Here’s a quick rundown of all the Big Bads by season:
Angelus – After sleeping with Buffy, Angel lost his soul and turned into Angelus, the former big bad, evil vampire with an affinity for really REALLY hurting people. Especially Buffy. He almost destroyed the world with Acathala, but Buffy put a sword through him in the 11th hour, sending him to hell. And her to LA.
Mayor Richard Wilkins III – Probably the funniest Big Bad, and huge germaphobe. He’d been alive for 100 plus years and was finally about to reach immortality by becoming a true demon. But his snakey self was vulnerable, and he blew up in the school.
Adam – Ugh. Hate this guy. Buffy used the essence of all her friends to pull out his power center and disintegrate it. Then the gang dreamt about the first Slayer.
Glory – Evil hell-bitch with a split personality she shares with mortal named Ben. After having found the key, Dawn, she tied opening a porthole to get her home to her own hell dimension, which would have destroyed the world. Giles took her out by killing her mortal half, Ben. Then Buffy sacrificed herself to save the world from being destroyed.
Evil Willow – Willow began to spiral in a drug/magic metaphor wherein her girlfriend Tara leaves her, and when they finally get back together, Tara dies at the hands of Warren. Evil goes all black hair and kills Warren and begins more destruction, only to be saved by Xander and his yellow crayon speech.
The First Evil – The culmination of all the evil in the world, and alleges that it cannot be defeated. It appears in various forms, including previous Big Bads, which makes the montage so awesome. Buffy can’t defeat the First Evil per se, but destroys the Turok h’an that the First sends to destroy the world, and all the Slayers. Spike helps in that destruction by wearing a trasnporty necklace that sends him to LA once the fight is over.
And there you have it. Buffy Big Bads. Love them or hate them, they make Buffy’s life more difficult, and certainly more interesting.
