>>326279All the toys from the original lines had names, dude, including Diaclone. They weren't sold in blank boxes. You even go on with your arrow diagram to show the truck's original Diaclone name.
People think that because a toy is called "Jet Robo", it doesn't have a name. Jet Robo is a name. It sounds generic to you, because you speak English. To the Japanese, it sounds (or sounded) exotic and cool. It would be like a guy called "Shinobi" in the US. We think it's a cool sounding name, but to the Japanese, it's just a word for ninja. But it's still a name, not a label.
(Convoy sounds like someone who could kick your ass. Optimus Prime sounds like a nerdly scientist.)
