That was a clusterfuck of sorts. I had Bumblejumper and Cliffbee (the yellow Cliffjumper and red Bumblebee, per their fan names). They were supposedly rare, but I don't recall them actually being rare. My parents got my brother and me both Bumblebees, since they were the same in different colors. Originally, we had a red Cliffjumper, and, when he broke, I could only find the yellow one to replace him. (No, he wasn't Hubcap. Hubcap had an orange face. I remember for years arguing with other folks that there had, indeed, been a red Bumblebee and yellow Cliffjumper, and the yellow Cliffjumper was distinct from Hubcap.) My friends and I always either used them as generics, or we made up new characters for them to be, or, sometimes, pretended that Cliffjumper and Bumblebee had the ability to change colors to go undercover.
I'm sure my Bumblejumper is around somewhere. It was the second version, with the rubsign. (Again, not Hubcap. He pre-dated Hubcap by at least two years.)
Edit: I take it back. "Bumblejumper" is usually used to refer to a figure I never saw, more commonly called "Bumper." He was a third Microman figure with the same transformation scheme, who somehow found himself given an Autobot insignia and tossed on a Cliffjumper card. (It's speculated he may have existed on the Bumblebee card as well, but no evidence has been found.)
