O-Dog

 is a Raider character walking around the Courtyard of Haven. He has purple hair and facial hair, and refers to everyone as "meat", like most Slavers. He (like every other Pitt Raider and Slaver) will turn hostile against the player and the rebelling slaves should they choose to side with Wernher.

Appearances
appears in the Fallout 3 DLC The Pitt.

Trivia

 * His name and proclivity for referring to people as meat products is a reference to Pittsburgh's landmark restaurant in Oakland (Uptown in game, where O-Dog is located), Essie's Original Hot Dog Shop (shortened simply to "The O" by locals). Hot dogs from "The O" are referred to simply as O-Dogs, hence his name.
 * Could it be that he is 3 dogs brother since he stated he came from a Pitt-like place?
