Stewie Griffin /

Stewart Gilligan "Stewie" Griffin is a main character of the animated series Family Guy voiced by Seth MacFarlane. Once obsessed with world domination and matricide, Stewie is the youngest child of Peter and Lois Griffin. His older siblings are Chris and Meg. Stewie is considered to be the show's breakout character. Wizard magazine rated him the 95th greatest villain of all time. Stewie is a one-year-old prodigy who has a very sophisticated psyche, is able to speak fluently, and has a peculiar English accent. He reached his first birthday in the season one episode "Chitty Chitty Death Bang", and has remained the same age ever since, although it is presumed that he has aged to the age of at least four or five, as he is seen in several episodes going to Pre-school. While highly literate and able to cite pop culture references that date to long before his birth, he is also entranced by Raffi and the Teletubbies. Stewie succumbs to other weaknesses of children his age – he believes Peter has truly disappeared in a game of Peek-a-Boo, talks to his teddy bear (Rupert) as if he were alive, is overcome with laughter when Lois blows on his stomach, and has no idea how to use a toilet.
