Hilarious in Hindsight: The fact that the GoBots toyline was originally a competitor to Transformers became this after Hasbro, owner of the Transformers franchise, bought Tonka, owner of the GoBots, in 1991 and therefore are the current owners of the GoBots franchise.
Misblamed: Many people have dismissed Challenge of the GoBots as a ripoff of the Transformers franchise, which is only partially true. The GoBots toyline actually predates that of the Transformers.
On technical levels, the Transformers cartoon did beat the Gobots first. While in actual American toylines, Gobots came first. However each being based on earlier foreign toylines complicate it even further. In a way Transformer parts came first, but the first fully formed toy that would be sold as a gobot came before the first fully formed to that would be sold as a tranformer. You may see any example brought up in "who came first" debates involving the two franchises.
Moral Event Horizon: Cy-Kill crosses it in "Clutch of Doom" when he crushes one of the condensed globes of Earth's population in order to coerce Leader-1 into turning himself in. While it's later revealed that the globes containing Earth's inhabitants were swapped with hollow fakes, it's still particularly vile that Cy-Kill would murder a billion people just to force Leader-1 to surrender.
Never Live It Down: Scooter is generally disliked for being a coward who always complains about getting into dangerous situations even though he actually works up enough courage to save the day on more than one occasion and gradually grows out of his cowardice as the series progresses.
So Bad, It's Good: Rocklords. Think Transformers, but instead becoming something cool like a car, a dinosaur, a plane, or a tank, they became rocks! You could choose between granite, quartz or shale amongst others!
The really stupid bit is in the movie - they transform and roll out and slowly clump away down the road like bricks turning under their own power.
So Okay, It's Average: The general opinion of the show amongst people who have actually watched it is that it's a decent and watchable cartoon even if it is seen as a ripoff of Transformers.
The Scrappy: Scooter. Oh gods, Scooter. He probably would have been more popular if they hadn't made Frank Welker give him the most annoying voice possible. Also Nick - who was basically Scooter's best buddy.
In addition, unlike his Transformers counterpart Bumblebee, Scooter was cowardly and his first response to most bad situations was to gulp in fear. Heck, in the very first episode Leader 1 declares that he wants to launch a full scale assault to finish the Renegades off once and for all, and Scooter's reaction is to gulp and ask if he isn't being too hasty! You could argue he recognises his lack of combat skill or ability, but Bumblebee wasn't afraid to risk his life if it would help the Autobots out, despite his diminutive size.
Viewer Gender Confusion: Due to the female GoBots lacking feminine traits, it's very easy to mistake one for a male GoBot, at least until they speak.
