Peter Griffin

Peter Löwenbräu Griffin Senior, born Justin Peter Griffin is a stereotypical obese, blue collar worker. According to his birth records, his original name was Justin Peter Griffin. He is the protagonist of the show and title character.

He is mentally retarded and usually says whatever is on his mind, often in the wrong place, and at the wrong time. Peter Griffin is a larger than life caricature of middle America. He is epitomized by complete social ineptitude and an exceptionally low I.Q.. He has no personal identity of his own and is swept away by the whims of whatever comes to mind, be it patriotism, racism, anti-racism, homosexuality, family values, etc. His character is a dig on how debase American society has become.

Peter attended Providence High School. Together, Peter and Lois have three children, Chris, Meg, and baby Stewie. After a mix up at a sperm bank, Peter also became the biological father of Bertram. Previously due to selling sperm to raise money for dial-up modem impression lessons, he also found himself the father of many other children in "A House Full of Peters". In addition, he and Lois had a child named Peter Griffin Jr. who died when Peter shook him too much as revealed in "The Juice Is Loose". Out of pity he also adopted an intellectual talking dog named Brian who formerly lived on the street as a stray, an accepted fact in Brian's two adoption stories.

Meg Griffin
Meg is the unwanted daughter of Peter and Lois Griffin. But, in one episode, when Meg was Peter's driving buddy, when Meg beat up a fellow Quahogian, Peter replied that it was awesome. They had fun driving until Joe Swanson gave Peter his license back.

Chris Griffin

Lois is Peter's wife. Sometimes Lois gets angry at Peter for being like a child.
