A highly toddler who talks and acts as an adult, Stewie began the series as a Megalomaniacal 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 (something possibly foreshadowed in the direct-to-video film ""). 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. Stewie is also the only character to appear in every episode of the series.
