Roger (voiced by Seth Mac Farlane) is one of the main characters in the animated comedy American Dad!. He is a space alien (whose appearance resembles that of the greys) living with the Smith family, Roger is sarcastic, surly, and speaks in swish; this and other traits have led some to speculate as to Roger's sexuality, but the discussion might be moot, as he is, after all, an alien. Roger came to live with the Smith family after saving Stan Smith's life in Area 51.
