Buffy The Vampire Slayer: 10 Best Characters Who Only Appear In One Episode

10. Lissa (Season 7, Episode 14)

Xander’s love life is a never-ending failure. All his romances fall apart, and even his wedding day proves to be a disaster. Then, in the middle of Season 7, he manages to make yet another romantic blunder.

After meeting an attractive woman called Lissa, he scores a date at Espresso Pump. During the date, Lissa suggests they go and do something fun, and the next time we see Xander, he’s trapped in a ritual sacrifice above the Seal of Danzalthar:

“This can’t just happen. It can’t just keep happening that demon-women find me attractive. There’s gotta be a reason.”

When watching this episode for the first time, there’s no indication of Lissa’s true allegiance, so her betrayal is a great – and slightly amusing – plot twist.

Buffy and co. soon arrive on the scene, save Xander from a terrible fate, and defeat Lissa by chopping off her head. It’s a quick end for such an interesting character, and we’re left with plenty of unanswered questions about her abilities and her partnership with the First Evil.
