Sphinx is an major character in the beginning of Big Dog's series of events in MotorStorm: Apocalypse. After a wrecked helicopter passes him by down a nearby street, he is approached by Big Dog to do a small favour. The graffiti artist turns a spotlight from the wrecked gunship into a signal, based on the MotorStorm logo. Mash later sees this signal when approaching the rally point.
He is voiced by Arif S. Kinchen.
