I've thought of the Garthe angle with his getting a hold of KARR as well as I'm sure many have. Yeah his CPU might have survived and for whatever reason the Foundation didn't get a hold of it after he was destroyed and kept it, it might for whatever reason have been lost after the original show, but it's just stretching things too far. I could see their work on trying to reprogram it but maybe being unable to due to KARR's programming being "hard coded" into his CPU. Maybe the plans for the new KITT were stolen and they'd go the "twin" route again. But I dunno, it would have to be an amazingly well written episode.
As for Garthe, he remains dead, D-E-A-D, dead. But as I was thinking about the other night, he could have off spring. I just don't want him to return, we don't need Hasslehoff with a soul patch again. Anyway, what I came up with is this as a backstory to what would happen.
Shortly before the events of Goliath Returns Garthe had a fling with some woman who ended up having twins, a girl and a boy. Their mother, ashamed of who Garthe was didn't tell them who there father is until they were older, the son having this notion that his father was really the good guy left home and adopted "Knight" as a surname. He tried to get his sister to join him but she refused so he leaves and she stays, the brother and sister's relationship is strained and they have little to no communication.
So then several years go by and the sister (who wants nothing to do with her "father" or his legacy) starts working for a company that does business for the FLAG where she meets Mike, she becomes a semi-regular and they at some point start dating. Neither of them know that their fathers were enemies until the day her brother finally emerges as part of a group that's gone to break into FLAG to steal their secrets and that leads to Mike having to hunt them down. He catches what he thinks is all of them and recovers the missing data/merchandise or most of it... He and KITT somehow miss "Garthe Jr" (who would look nothing like Mike, especially since they share no DNA) who gets into an awaiting vehicle. The voice ask him if he got it to which he replies by handing over what he stole, the items include the original formula for the Knight Compound/MBS, designs for the new KITT (which apparently are lazily stored) and KARR's CPU. The voice which is that of an old woman says "good" and we get the reveal that it's the now very old and still very pissed Elizabeth Knight! But we still wouldn't know who he is until the next appearance.
The fallacy in all this would be that they build a new and improved KARR still remains technologically inferior to the new KITT despite having blue prints, say they don't have the budget but they can use them to try and find a weakness. To me it would be a little more enjoyable than there being even playing field or the bad guy having the upper hand. As much as I liked KARR, there's just a time where he pretty much needs to be put in his place and have a realization that he's now an obsolete prototype. Of course that's not to say he couldn't have a vast amount of improvements, along with a new body but in the end still less advanced than the KI3K. Elizabeth Knight (who obviously would be very very old) or whomever she's allied with shouldn't have the resources to put together a car that is superior or even equal. She pretty much tells "Junior" what he wants to hear and manipulates him. As for where she'd get her money, I really don't know how to go about that, maybe someone else supports her and a part of their arrangement had to do with whomever is backing her having a deal regarding what was stolen. Though after all these years I dunno how it'd work unless she's in Jennifer's good graces... I can't remember, were Jennifer and Garth only half siblings or did they share the same mother as well?
Anyway, it could be a multi-episode arc where they go off to do something else while the "bad guys" get things together. I don't think I need to tell anyone where this would go, it's fairly predictable. The Garthe having kids thing would fit with Mike's age perfectly if going by the original air date for the Goliath Returns episode(s).
Perhaps Jennifer Knight could have kids of her own and if not be the head of FLAG, be the head of Knight Industries, if it still exist and there could be friction somewhere between her kids and Mike or maybe everything has smoothed over after all these years. Everything would be a bit convoluted but as long as the show isn't overly serious, hopefully people would look past it. If anyone cares I'll expand on this more later, I already did quite a bit more than some tweaking though the basics are the same. Anyway, I've been up for way too long and I need sleep..
