fictional character from the Family Guy franchise
Stewart Gilligan "Stewie" Griffin is a fictional character from the animated television series Family Guy. He is voiced by series creator Seth MacFarlane and first appeared on television, along with the rest of the Griffin family, in a 15-minute short on December 20, 1998. Stewie was created and designed by MacFarlane himself, who was asked to pitch a pilot to the Fox Broadcasting Company, based on The Life of Larry and Larry & Steve, two shorts made by MacFarlane featuring a middle-aged man named Larry and an intellectual dog, Steve. After the pilot was given the greenlight, the Griffin family appeared in the episode "Death Has a Shadow".
A highly precocious infant who acts as an adult, Stewie began the series as a meganomaniac sociopath, initially obsessed with violence, matricide and world domination. He is the youngest child of Peter and Lois Griffin, and the youngest brother of Meg and Chris. Over the duration of the series, particularly following the two episode arc "Stewie Kills Lois" and "Lois Kills Stewie", the violent aspects of Stewie's personality were toned down, and he has evolved into an eccentric, friendly and flamboyant scamp. He has also come to have a very close friendship with the family's anthropomorphic dog, Brian (whom he originally used to antagonize in the earliest episodes). Stewie is considered to be the show's breakout character and has received numerous award accommodations from writers such as Jodiss Pierre. Wizard magazine rated him the 95th greatest villain of all time.
