Buffy The Vampire Slayer: 10 Best Single Episode Villains

2. Sweet

Episode: Once More, With Feeling (Season 6, Episode 7) Sweet was the nickname of a very powerful demon whose mere presence could cause the inhabitants of an entire city to sing and dance as though they were living in a musical, which would also cause some of the victims to spontaneously combust if they did it for too long. People under Sweet's spell would sing about anything, from dry cleaning to relationships - and it also caused them to give away secrets, such as Buffy revealing that she was cruelly torn out of heaven when Willow Rosenberg and Buffy's other friends resurrected her. Sweet was summoned by Xander, supposedly, who claimed he wanted to bring some joy to Sunnydale before his upcoming wedding to Anya. However, this is dubious, as many viewers believe Xander simply stepped in to take the blame when people were initially blaming Buffy's sister, Dawn Summers. Sweet was supposedly bound by certain rules such as marrying whoever summoned him and taking them to his own hell dimension, but seemed to have the authority to ignore them if he so desired (and given some of the reality-warping powers he displayed, this authority wasn't surprising). Ultimately, Sweet left of his own accord, not wanting Xander to be his 'queen'. He left with the parting shot that, having caused a lot of secrets to be revealed, the Scoobies hadn't come out of the encounter well. Sweet's presence made for a truly unique, entertaining and award-winning episode, as the cast (most of whom weren't singers or dancers by any stretch of the imagination) gave impressive performances of a nature we had never seen before.
