Gaff
Gaff, a mysterious character in the film, presents his compulsory invitation to Deckard in a street lingo called Cityspeak, a mixture of Spanish, French, Chinese, German, Hungarian, and Japanese. He is played by Edward James Olmos. As a fellow cop, he is quickly identified as being very different from Deckard through the ways he dresses and behaves. He tends to make little Origami figures. The last words heard in the film are spoken by him: "It's too bad she won't live. But then again, who does?"
Gaff walks with a cane and a noticeable limp.
The sequel by K.W. Jeter mentions that Gaff is killed in the line of duty. At the beginning of the novel, Bryant has just returned from the funeral and expresses his distaste for the Cityspeak written on Gaff's headstone.
