The appearance of the "God" character is the traditional depiction of the Abrahamic God in the Western world: a white-haired Caucasian man wearing a white robe.
The depiction of God on Family Guy is one of the most controversial components of the series. The show's depiction of God is primarily featured in episodes and/or gags satirical to religion, where He is often portrayed in a less-than-flattering if not outright negative, almost sacrilegious light. Some gags depict Him in Heaven, while others have Him appearing as a human being on Earth, interacting with its inhabitants.
Many of the gags featuring God completely revise what has been established in Scripture. For example, in "Untitled Griffin Family History," God uses Chuggs' cigarette lighter to "light a fart on fire," thereby setting in motion the universe's creation as depicted in the Big Bang theory.
In "Fifteen Minutes of Shame", He nearly grants Meg's wish to have God "kill me now," only to have His sniper-style attempt interrupted by a phone call.
Stewie explains to Brian that Jesus didn't really die on the cross in "Stewie, Chris & Brian's Excellent Adventure" as God discovers in a cutaway that it was really due to cocaine and trauma to the colon.
