KARR (Knight Rider)

Once KITT was constructed, it was presumed that its evil prototype KARR (voiced by Peter Cullen) 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. When two thieves, Tony (Michael MacRae) and the Rev (William Sanderson), break into the warehouse where KARR – who is entirely identical to KITT with the exception of the yellow/green voice module on its dashboard and as well as the different speaking voice – is "sleeping", they unwittingly reactivate it, and KARR escapes.

When the two thieves realize how useful the vehicle could be, they use KARR to go on a crime spree, whilst Michael and KITT frantically try to catch up with KARR and stop it before anyone is seriously hurt. Bonnie devises a high-powered laser, the only known way to stop KARR, which must be fired from KITT directly into KARR's red scanner. However, when KARR needs maintenance, Tony kidnaps Bonnie before the laser can fully be calibrated. Although Michael rescues Bonnie, she is unable to get a clear shot at KARR with the laser and it escapes.

KARR's only weakness is its primary directive of self-preservation and Michael uses this to his advantage. When KARR threatens to destroy KITT in a head-on collision, Michael plays chicken with it, on a hunch that KARR will veer out of KITT's path in order to protect itself. KARR indeed swerves out of the way, but unable to stop in time: it drives off a cliff and seemingly explodes in the ocean (using footage of the climactic scene from the 1977 film The Car, footage that was also used for KITT on a couple of other occasions).

Trust Doesn't Rust was also printed in book form, written by Roger Hill and Glen A. Larson, following the story and general script of the original television episode, expanding some areas of the plot and adding several extra secondary characters.[1]

KARR (now voiced by Paul Frees) was only believed to have been destroyed. It was instead damaged and ended up buried in the sand on the beach below the cliffs. When the tide had gone out, a young couple, John and Mandy, stumble upon the partially buried car, dug it out, and reactivate it. This time, KARR is truly furious and has only one clear motive: revenge against Michael and KITT.

KARR is still damaged after the last encounter with KITT and forces John to serve as its driver, and also to carry out some cosmetic modifications to its paintwork in a ravine in order to forever differ entirely from KITT. KARR challenges Michael and KITT to a final showdown. After releasing the young couple, KARR fires a stolen laser and damages KITT. However, Michael and KITT destroy KARR's laser by reflecting the beam back to the emitter. Damaged, KARR prepares for another attack. KITT and KARR both turbo boost and collide in mid-air. KARR is unfortunately blown to pieces, but Michael and KITT fortunately survive the impact. At the end of the Knight Rider episode, however, KARR's motherboard — i.e. KARR itself — can actually be seen lying undamaged on the ground amongst the vehicle wreckage, its yellow LED's still blinking – suggesting to the viewers that KARR is actually still "alive".

Originally, KARR appeared entirely identical to the titular heroic character of KITT (all black with a red scan light bar), with the only physical difference being a greenish-yellow LED voice modulator on its Knight Industries dash (for the pilot and as well as for the first half of the first season, KITT's voice modulator is a red square that blinks on and off as it talks; KARR's voice modulator is the prototype to the one seen on KITT from the mid first season onwards, after it was received positively well by viewers) and the only other difference being the evil voice. When KARR returns in "K.I.T.T. vs. K.A.R.R.", KARR's scan bar is now amber/yellow rather than red like KITT and KARR instead appears very similar to KITT's, and is still 100% black like KITT for the first half of the evil clone vehicle return appearance.

KARR later gets a brand new black and silver two-tone paint job incorporating a silver lower body into its familiar 100% all-black finish to truly forever differentiate against KITT. KARR's scanner originally made a creepy low droning noise, but in the comeback episode it instead sounds similar to KITT's but with a slight reverb audio effect added to it. The sound of KARR's engine, originally sounding rough and "fierce", here instead sounds similar to KITT's, again effected by a reverb. In "Trust Doesn't Rust," KARR had no automobile license plates. In KARR's second appearance, it had a California state automobile rear license plate that read "KARR." Despite various other significant major changes, KARR's two TV Knight Industries dashboard remains correct with Knight Rider continuity – it still has the earlier version of the Knight Industries dashboard as previously seen on KITT in season 1–2 as well as in KARR in his debut appearance in Knight Rider, whereas by the time of 'KITT Vs KARR', Bonnie had updated all of KITT's dash and various functions at the start of the third Knight Rider season as well as at the start of the fourth Knight Rider season.

KARR's evil personality is also somewhat different in the comeback episode. Its childlike perceptions are diminished into a far more devious personality, completely cold and downright bent on revenge. Its self-preservation directive, Its naive, animalistic behavior is truly no longer in play. When KARR is very truly close to exploding after receiving severe damage; it willingly turbo-jumps into a mid-air collision with KITT, hoping that its own destruction would also spell its good clone counterpart's. Even KARR's modus operandi is different; servicing enough in the debut episode, it instead aims to actually make use of other people to serve its own needs. One explanation of this major significant change could be as a result of the vehicular damage it received after falling over the cliff at the end of "Trust Doesn't Rust", causing far further malfunctions in its vehicular programming. Indeed, KITT itself is also seen to malfunction and suffer change of personality as a result of damage in several other episodes.

In "Trust Doesn't Rust" Season 1, Episode 9 (1982) in the original Knight Rider series (1982-1986) KARR was first voiced by Peter Cullen and in the new Knight Rider series "Knight to King's Pawn", the voice of KARR was once again provided by voice actor Peter Cullen. Cullen is better known as the original first voice of the heroic Autobot leader Optimus Prime in the G1 Transformers 1984-1987 cartoon series and the 1986 Transformers: The Movie before his unfortunate character death and his later return appearances in the original American Animated Generation 1 The Transformers series as well as plus once again reprising his role as the voice of Optimus Prime in Transformers Prime TV Series 2010–2013 and as well as the 2013 Transformers: Predacons Rising TV Movie Finale and as well as also in The Transformers Live Action Film Series Franchise, and had a previous working relationship with series creator Glen A. Larson after voicing several Cylon characters in the original Battlestar Galactica. In "K.I.T.T. vs K.A.R.R.", Season 3, Episode 6 (1984) in the original Knight Rider series (1982-1986), KARR was now instead voiced by late legendary voice actor Paul Frees, best known as the voice of Boris Badenov in the popular series The Rocky and Bullwinkle Show and the voice of Ludwig Von Drake in the popular anthology series, Walt Disney's Wonderful World of Color as well as being the original first voice of Ghost Host in the Haunted Mansion ride at Disneyland. Like William Daniels, the voice of KITT, who was never credited on-screen, Frees was also uncredited on-screen for his role, the voice of KARR.

KARR 2.0 Knight Auto-Cybernetic Roving Robotic-Exoskeleton (voiced by Peter Cullen) is mentioned in the new Knight Rider series episode "Knight of the Living Dead", and is said to be a prototype of KITT (Knight Industries Three Thousand). The new KARR acronym was changed to "Knight Auto-cybernetic Roving Robotic-exoskeleton". Instead of an automobile or a muscle car, a schematic display shows a heavily armed transformer humanoid-looking robot with wheeled legs that converts into an ambiguous off-road vehicle.

In the episode, a spy infiltrates the SSC and activates a self-destruct program within KITT, placed there secretly by Dr. Graiman. In order to save KITT's operating system (which is given priority over its memories), Michael and Sarah transmit the files to the back-up computer at the headquarters, but the transmission is also intercepted by an unknown third party. It is stated that KITT, KARR, and the base's back-up computer are the only systems able to run the program, and leaves Dr. Graiman with only one conclusion: KARR is still out there, and someone is trying to reactivate it.[2]

When KARR finally appears once again in the episode "Knight to King's Pawn", it takes a form once again similar to KITT as a 2008 Ford Shelby Mustang GT500KR, but has a yellow scanner and 100% yellow color voice module and is once again 100% black like KITT. Once again, similar to the original character, this entirely different "KARR" project (2.0) had an artificially intelligent talking A.I. that was programmed for self-preservation, and it was deactivated and placed in storage after it unfortunately reprogrammed itself and killed seven people.

KARR returns in the episode "Knight to King's Pawn", with Peter Cullen reprising his vocal role as KARR using his Optimus Prime/Nemesis Prime voice from the Hasbro Transformers Franchise. A pre-recorded message from Dr. Graiman reveals that Michael was KARR's driver and his memories were erased after KARR became uncontrollable. He says that he knew of and opposed Alex Torres and the NSA's plans to reactivate KARR, as they wrongfully believe KITT's artificial intelligence will overwrite KARR's evil programming flaws. During the dismantling of the SSC (FLAG's control centre), KITT's talking A.I. chip is removed and delivered by Torres to the NSA, where it is later installed into KARR. Michael vows to end this once and for all, and infiltrates Area 51 to rescue KITT, using another chip built by Billy. KARR activates itself, viewing the reactivated KITT as a threat that must be forever terminated. Alex states that he is now in charge and KARR must take his orders; KARR agrees, but then merges Alex with him as a driver to seek out Michael.

KARR seems to believe that it is its destiny to merge with Michael as before, and comes after KITT to destroy it and get Michael back. Despite KITT lacking its transformation protocols and weapons, Michael takes it into battle anyway. Using a grappling hook, Michael and KITT pull out KARR's chest plate, freeing Alex, and Turbo Boost through its body, destroying it in a manner similar to the destruction of KARR in the original series. Given the unfortunate short nature of the battle and the ambiguity of KARR's fate, it is possible that the new KARR might return yet again, although in the following episode entitled "Exit Light, Enter Knight" Michael is told that the KARR Knight Automated Roving Robot project has unfortunately been permanently abandoned.

KARR is once again similar to KITT, also a 2009 Ford Mustang Shelby GT500KR based on the Knight 3000 and is once again 100% all Black like KITT and as well as 100% all black like the new KITT. The real main difference between KITT and KARR is that KARR has a yellow scanner (in the original series it was more amber/yellow and in KARR's first debut appearance it was red just like KITT) and the yellow scanner noise is lower in sound with more of an echo. The sound difference is especially notable when KITT is racing toward KARR while KARR is still in Ford Mustang mode and KARR's voice module originally yellow/green is now 100% yellow color to totally match the color of KARR's yellow scanner.

In "Knight of the Living Dead" a schematic display shows KARR as a heavily armed humanoid-looking Transformer-like robot with wheeled legs that converts into an ambiguous off-road vehicle, but when KARR returns in 2009 for its third appearance in "Knight to King's Pawn" it is once again similar to KITT and is once again 100% all black like KITT. KARR is now a 2009 Ford Mustang GT 500 KR, like KITT 3000; the only difference is that it has a yellow scan light bar. In the original Knight Rider series it was more amber/yellow and in KARR's debut appearance in the original Knight Rider series, it was red just like KITT, and KARR's voice module originally yellow-green in the original series. It is now 100% yellow color and KARR's yellow scanner sounds much lower with much more of an echo which sounds similar to KITT's. The sound is especially noticeable when KARR is chasing down KITT while it is still in Ford Mustang mode. Peter Cullen reprised his role as the voice of KARR in the 2009 Knight Rider episode, "Knight to King's Pawn." as KARR 2.0 (Knight Auto Cybernetic Roving Robotic Exoskeleton).
