Red is a minor character. Red appears in "Mind Share" as one of the alien prisoners. He skipped breakfast, and he knows about a hole to the prison sewer behind a poster. He knows it is 500 yards long, and he thinks it is disgusting but is wrong. He is described as the guy who knows how to get things.
He is a parody of Morgan Freeman's character from Shawkshank Redemption, even going so far as quoting some of his lines from the movie, including describing 500 yards as the length of "five football fields". Voice actor John Viener even reprises his Freeman impression that he occasionally does on Family Guy.
