The Mute: He's a hard as nails car-jacker.

The Obligatory Dialogue: Right at the end of the film, The Sphinx turns philosopher and gives a Shakespearian speech.

Silent But Deadly: The first time we see The Sphinx, he rescues Memphis from a local gang by beating the shit out of several of them, then blowing up their car.

Nothing compared to the havoc he used to wreak on opposition strikers though, eh Gazza?
