That's basically all the comic says. Edit: Didn't notice the post above me. You can read the comic yourself.
Man, I thought that comic was pretty good ten years ago.
Double Edit: Back to Convobat for a second. Everything I had read about him implied that he was released in that same period where Beast Wars hadn't quite established it's own identity yet. The wiki sort of backs me up:
But whatever.Just what character this toy represents is up for debate. The toy's bio claims he used to turn into a tractor-trailer (indicating Optimus Prime), but considering the timeframe of when they were written and the whole lack of a stance on who Primal "was" before the show and bla bla bla... it's just easier to file this under the same iffiness as the original toy bios set on modern Earth and leave it at that.
