O-Dog

 is a Raider character walking around the Courtyard of Haven. He has purple hair and facial hair, and in conversation frequently refers to everyone around him as "meat", to an excessive degree much greater than 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 add-on The Pitt.
