Charlie was conceived largely by accident, due to Amenadiel not knowing it was possible for an angel to impregnate a human woman. Linda suffered from a fainting spell a month after she and Amenadiel broke up, with Maze forcing her to go see a doctor. Learning that she was pregnant, Linda had the complete support of Amenadiel and Maze despite their lack of knowledge about babies or angel babies, for that matter.
Shortly after Charlie's birth, he was kidnapped by demons who were hoping to make him the new King of Hell. However, he was rescued and returned to his parents.
- Charlie is unique for being the first angel/human hybrid.
- Being half-angel, Charlie can be taken to and from Earth without dying.
- In "Orgy Pants to Work", Remiel said that they have to take him for heaven "for all eternity". This indicates that, as a half-angel, Charlie is immortal.
- Some of the other suggested names for Charlie were Zoriel, Zori, Ezekiel, Zek, Jack, Jackiel, Azmortiel, and Michael.
