Jeff Moreau, better known by his nickname "Joker", is the human pilot of the "Normandy", and is voiced by Seth Green. Joker is handicapped and has limited mobility due to suffering from osteogenesis imperfecta, but makes up for being a skilled pilot, as well as a sarcastic foil to Shepard. In "Mass Effect 2" Joker briefly becomes a playable character when the Collectors invade the "Normandy" to capture its crew in the absence of Shepard and the squad. He can develop a romantic relationship with EDI in "Mass Effect 3" if given some help from Shepard.
