like KITT 3000, the only difference is that he has a yellow scan light bar and 100% yellow color voice module. In the original series, it was more amber/yellow, and KARR's voice module originally yellow-green in the original series. KARR's scanner sounds much lower with much more of an echo. The sound is especially noticeable when KARR is chasing down KITT while he is still in Ford Mustang mode. History Once KITT was constructed, it was presumed that his prototype KARR had been deactivated and dismantled. However, the latter did not occur and KARR was placed in storage and forgotten following the death of Wilton Knight. In the episode "Trust Doesn't Rust", two thieves named Tony and the Rev break into the warehouse where KARR is "sleeping" where they unwittingly reactivated him, and he escapes with them. When the thieves realize how useful the vehicle could be, they use KARR to go on a crime spree. Michael and KITT are sent to recover KARR before anyone becomes hurt. Fearful of being taken back to storage and certain deactivation, KARR was unwilling to go back to the Foundation, and he flees when Michael and KITT come looking for him. They later kidnap Bonnie and force her to repair KARR, although she unsuccessfully tries to sabotage KARR. The Rev eventually refuses to help Tony and KARR any further, as he is concerned for Tony's safety, leading Tony to knock him out and abandon him. Michael rescues Bonnie, but KARR and Tony escape. KARR later abandons Tony so he'll have a better chance to escape from the police. When KARR threatens to destroy KITT in a head-on collision, Michael (remembering KARR's weakness) plays chicken with him, knowing KARR will veer out of KITT's path in order to protect himself. Unable to stop in time, KARR drives off a cliff and seemingly explodes in the ocean. KARR was only believed to have been destroyed, but in the episode "K.I.T.T. vs. K.A.R.R.", it is revealed he was only damaged and ended up buried in the sand on the beach below the cliffs. When the tide goes out, a young couple stumbles upon the partially buried KARR, digs it out and reactivates it. This time, KARR is furious and had only one clear motive: revenge against Michael Knight and KITT. KARR forces the young couple to disguise him and then drive him around to carry out
