Rinzler is CLU 2's right-hand man. Considered a master warrior, he uses two identity discs in combat and displays advanced acrobatic talent. Interestingly, the 2-Disc DVD edition of the original Tron revealed that in the late 1970s, Lisberger Studios had produced an early demo animation showing the character 'Tron' similarly armed with two "exploding discs", (see Tron Origins). Later in the story of Tron: Legacy, it is revealed that Rinzler is a reprogrammed version of Tron. He has several encounters with Sam Flynn through the film, and during an aerial fight sequence, remembers his past identity and turns against CLU. His ultimate fate is left unknown, although at the end of the movie when his red markings faded and went out they turned blue again, possibly suggesting that he is alive, or at least was for a short time after falling into the sea.
Rinzler is named after Lucasfilm Executive Editor, J.W. Rinzler, author of several books including The Making of Star Wars, The Complete Making of Indiana Jones, and Making of The Empire Strikes Back. Director Joseph Kosinski chose the name during a working session with the writers when one of Rinzler's books happened to be on the table.
Rinzler is played by Anis Cheurfa, a well-known martial-arts performer cast for his abilities. His stunts and acrobatic talents can be seen throughout the film. Rinzler is voiced by Bruce Boxleitner.
