Alexander Lavelle "Xander" Harris (played by Nicholas Brendon) was another good friend of Buffy. During season 4, Xander becomes romantically involved with an ex-vengeance demon, Anya (Anyanka), whom he later became engaged to, but left during the wedding in the episode "Hells Bells". It was said many times during the series that Xander was the person in the group who had no special powers at all, but still fought as much as everyone else, and, in season 7 ("Potential") Xander is named the "Seer" because he sees everything that is going on, because he's never actually in the spotlight, just next to it. Xander was often the character the writers used for comic moments. Xander was a major character in the series and saved the world (from Willow) at the end of Season 6, by telling her he loved her repeatedly, accessing the human love inside of her "evil" persona, created by Tara Maclay's death.
