Oz / (Seth Green) The wolf is inside me all the time, and I don't know where that line is anymore between me and it. (Wild At Heart)  Character Bio Character Name: Daniel Osborne Nickname: Oz Band name: Wild Dingoes Ate My Baby First episode appearance: 'What's My Line - Part I' (a mysterious computer company picked him and Willow as potential employees, during the school's career fair) Willow and Oz became friends, their relationship slowly becoming more intense (even though Willow still has some feelings for Xander). Oz soon graduated to a fully-fledged member of Buffy's team, often supplying transport as well as pithy comments. Oz is lead guitar in the a group called 'Dingoes Ate My Baby' (a reference to the story of Lindy Chamberlain which was dramatised in the 1988 Meryl Streep movie 'A Cry In The Dark').  He’s very bright, but had to return to high school for an extra year as he wasn't able to graduate, due to being a total slacker. He's also not very quick to catch on "So what you're really saying is....." Being A Werewolf After knocking about with Buffy and Willow for a while, Oz discovered that, like several members of his family, he is a werewolf! Every month, when there's a full moon Oz has to be locked into a cage in the library, so that he can't harm himself, or other people. One time Willow had to shoot him with a tranquilliser gun. In series 2, Oz starts to date Willow and their relationship lasts throughout the 3rd series. Oz discovers Willow kissing Xander and they break up for a while, but eventually get back together. Once again, they break up in the 4th series, when Willow discovers that Oz has slept with a fellow werewolf, named Verruca.

(The Harsh Day of Light, talking to Giles about his record collection) Willow: "Where is supportive boyfriend guy?" Oz: "He's picking up your dry cleaning, but he told me to tell you that he's afraid you're gonna get hurt." Willow: "Okay, Brutus. Brutus Caesar? Betrayal trusted friend? Back stabby?" Oz: "Oh, I'm with you on the reference, but I won't lie about the fact that I worry? I know what it's like to have power you can't control. I mean, every time I start to wolf out, I touch something deep dark. It's not fun. But just know that what ever you decide, I back your play." (Fear Itself) Oz: "Verruca was right about something. The wolf is inside me all the time, and I don't know where that line is anymore between me and it. And until I figure out what that means, I shouldn't be around you... Or anybody." Willow: "Well, that could be a problem 'cause people... Kind of a planetary epidemic." (Wild at Heart) Willow: "Oz... Don't you love me?" Oz: "My whole life... I've never loved anything else."
