Spike (the Turncoat) was the Big Bad for a couple of series; he was a vampire famed for killing Slayers. However, he developed an unhealthy fascination with Buffy. After an encounter with a behaviour-control chip that caused him pain if he attempted to harm a human, he fell in with the heroes in an attempt to survive. After a while, he fell in love with Buffy and went on a quest to regain his soul to prove himself to her.

Tara (the Healer) was a witch who met the group during the 4th season. She was a quiet, timid woman who was an extraordinarily strong empath (she could psychically "see" people's real natures). She was able and willing to fight but her real talent was as a peace-maker amongst the group and a voice of reason.

Wesley (the Redeemer) was a junior Watcher (one of the secret society who controlled the Slayers). After making a complete hash of his assignment, he was expelled from the society and became a freelance wizard/demon hunter. He later joined up with a break-away group led by the ensouled vampire Angel but it was always clear that his first priority was to redeem himself from his own failures, both as a Watcher and as a protector to his charge, Faith. It was never clear if he was entirely loyal to Angel's group.

Faith (the Renegade) was a second Slayer, called through a magical short-circuit induced by Buffy being revived from clinical death by CPR. She was a poorly-socialised young woman with a shopping list of mental and emotional issues. Always a bit of an outsider, she eventually turned Dark and became a significant and recurring threat until she was defeated in single combat by Buffy. She later rejoined the Light after awakening from a coma but she retains the hard, edgy feel of an anti-hero.

Wolfram and Hart (the Evil Corporation) are an international law firm, whose Senior Partners (Mr. Wolf, Mr. Ram and Mr Hart) are ancient demons. They are a force of insidious evil, always on the look to turn people to evil through trapped 'solutions' to their problems, to protect the evil from the consequences of their acts and to promote the interests of the Dark through law, politics and finance.
