K.A.R.R is the prototype version of K.I.T.T, and built by his company Knight Industries. Upon completion of the vehicle, K.A.R.R's CPU was installed and activated. However, a programming error made the computer unstable and potentially dangerous. The project was put on hold and K.A.R.R was placed in storage until a solution could be found. Unlike K.I.T.T, whose primary directive is to protect human life, KARR was programmed for self-preservation, making him a ruthless and unpredictable threat. K.A.R.R first appeared in the Season One episode Trust Doesn't Rust where he seemingly met his demise at the end. However, he was so popular with viewers that he was brought back again in the Season Three episode K.I.T.T. vs. K.A.R.R.
