Darth Stewie was the main, later secondary antagonist of the Family Guy version of the Star Wars Trilogy. He was a parody of Darth Vader and played by Stewie Griffin. He was also the "father" of Luke Skywalker/Chris Griffin. He was voiced by Seth MacFarlane, the same person who also provides the voices for Stewie Griffin's original incarnation, Peter Griffin, Brian Griffin, and Glenn Quagmire on the show.
