Although this article is about an official minifigure, it never existed in physical form or appeared in any official LEGO sets.
K.A.R.R. was the prototype of the car of the future originally designed by Wilton Knight and built by his company Knight Industries. Upon completion of the vehicle, KARR's CPU was installed and activated. However, the programming made the computer potentially dangerous. The project was put on hold and the car was placed in storage until a solution could be found.
Unlike KITT, whose primary directive is to protect human life, KARR was programmed for self-preservation, making him a ruthless and unpredictable threat. He does not appear as streetwise as KITT. He is very naïve and inexperienced, with a child-like perception of the world. This occasionally allows people to take advantage of his remarkable capabilities for their own gain. Despite this, he does ultimately consider himself superior and unstoppable and due to his programming, the villains don't usually get very far. KARR demonstrates a complete lack of respect or loyalty, going so far on one occasion as to eject its driver to save weight and increase its odds of escape.
KARR first appeared in the season one episode "Trust Doesn't Rust", and 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.". KARR also appears as the enemy of KITT and his driver Michael Knight in the Knight Rider video game produced by Davilex International under license.
