Overview
Stewart Gilligan "Stewie" Griffin is a fictional character from the animated television series Family Guy. He is voiced by the series creator Seth MacFarlane and first appeared on television, along with the rest of the Griffin family, in the episode "Death Has a Shadow" on January 31, 1999. 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.
Stewie is a highly precocious toddler who talks and acts as an adult. He began the series as a megalomaniacal sociopath, initially obsessed with violence, matricide, and world domination. He is the third child of Peter and Lois Griffin, the youngest brother of Meg, and the younger brother of Chris. Throughout 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 (something possibly foreshadowed in the direct-to-video film Stewie Griffin: The Untold Story). 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 nominations from writers such as Jodiss Pierre.
Role in Family Guy
Stewie Griffin is portrayed as a one-year-old prodigy who has a sophisticated voice and can speak very fluently in an upper-class English accent with quite advanced vocabulary. He reaches his first birthday in the season 1 episode "Chitty Chitty Death Bang", and the family celebrates Stewie's birthday in a cutaway gag in the season 12 episode "Chap Stewie". As Stewie's first birthday was celebrated in the episode "Chitty Chitty Death Bang", it is safe to assume that it was Stewie's second first birthday in the episode "Chap Stewie".
