Seth MacFarlane voices four of the show's main characters: Peter Griffin, Brian Griffin, Stewie Griffin and Glenn Quagmire. MacFarlane chose to voice these characters himself, believing it would be easier to portray the voices he had already envisioned than for someone else to attempt it.
Other voice-over roles of his include Dr. Drakken and Motor Ed on Kim Possible, Brother Blood on Teen Titans, Rico in The Penguins of Madagascar, Fu Dog and Ogre In American Dragon: Jake Long, Niblet on Pound Puppies, the Scotsman on Samurai Jack, and as the voice of Shnitzel on Chowder.
