Infatuated with Vikia the sniper, O-Dog is more than competent with precision-rifle weaponry. He competes with Duke to get Vikia's attention, almost always unsuccessfully. He deems newcomers not as meat but simply as a "higher grade of sausage."
"Hey, it's not pretty, but it's the truth. We're all just meat in the grinder out here. Today's hotshot is tomorrow's Trog-chow. Nothing to it but to be the best, and eat our fill before we're next on the plate. Work hard and you might just be a grade-A cut like me!"
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.
