Peter is the husband of Lois Griffin and the head of the Griffin household. He is the father of three children and is best friends with a talking dog, Brian. His intelligence is often questioned and according to an I.Q. test he is "mentally retarded". He is constantly making the wrong choices which lead to wars and mostly, other people's misfortune, including his wife and children. He is in a constant battle to keep his wife Lois, who has shown unrelenting love for him, but for whom many in the town want. No matter how bad the situation Peter creates, he always seems to create a peaceful resolution through more stupidity.
