There really wasn't much GoBots mythos. It really was a shitty knockoff. Here's what I can remember:
1) They came from a robotic world called Gobotron. I'm not making that up. That should kill any suspicion there was more to this cartoon than "let's rip off the Transformers!"
2) Swear to God, the factions were called Evil GoBots and Heroic GoBots.
3) While on Gobotron, they turned into Earth vehicles.
4) Their only weapons were "lasers" fired from their fists. Except for Scooter, who didn't have any lasers, since he was supposed to be a kid, or something. Even warplanes didn't have any missiles.
5) Their transformations (gobomations?) exactly matched the toys. This meant that faces that were visible on the underside of cars and such were equally visible in the cartoon. The only exception was, again, Scooter, who had a totally different transformation from the (surprisingly cool) toy so that his moronic face would be where the headlight should normally appear.
6) They came to Earth in the present. I don't recall there being any explanation.
7) Their names were always silly. Always. Even when they were names that would be cool for a Transformers (like Turbo), they were silly for the GoBots.

The human characters were knockoffs of Transformers humans, particularly Chip, the Witwickys, and a particularly transparent knockoff of Doctor Archevil (whose name always looks retarded when written).
9) They had human brains. This was never explained aside from being mentioned in an episode where some super-robot had to accept the Evil GoBots were imperfect because of their human brains.
10) Cy-Kill was a sort of half-assed Megatron. Leader-One was a cross between Optimus Prime and Adam West's Batman, though without any of the cool. The other two main Heroic GoBots were Scooter, who makes Wheelie from the Transformers movie look like fucking Adrian Brody in the Pianist, and Turbo, a sort of hybrid Ironhide/Sideswipe type whose only memorable trait was the incredibly stupid catchphrase "Time to go!" He uttered it at least six times per episode. I can't remember the two other main Evil GoBots. There was, of course, a rotating cast of other toys you could buy.
Here's my idea: since GoBots was a total ripoff of Transformers, why not write the fucking awesome Transformers movie anyone but the Orci/Kurzman/Bay team would've come up with, and simply switch all characters from Transformers to GoBots? Anything from Transformers not in the first two movies is fair game (for instance, the two main humans can be Spike and Sparkplug, maybe mentioning their brother, Buster, but the last name Witwicky is off-limits).
Imagine....
"Four million years ago, they came to Earth from Gobotron. Heroic
GoBots Guardians and Evil
GoBots Renegades, locked in an endless civil war. Now, on Earth, they continue their conflict, disguising their presence from humanity by converting their bodies into automobiles, airplanes, and other mechanical devices. It is a world transformed, a world where things are not as they seem--it is the world of the GoBots!"
