I always thought Robot Master should've killed G B Blackrock and assumed control of the NeoKnights.
Budiansky loved to forget things. Like Circuit Breaker. Where was she supposed to be for all those years? Or the Roadjammers? Set up a major thorn in the side of 'bots and 'cons, then leave them in limbo. Jinkies!
Simon Furman, on the other hand, I blame for my geekiness. I picked up Transformers 56 and 57 on a whim one day and loved them. It was on my subsequent journeys in search of back issues I'd missed (about 50-60 of them in all) that I branched into other comics that looked cool or I'd heard of. One cover in particular of a half-naked wild man (who I already knew was Wolverine) slashing some daffy orange-smelling man apart, as well as the story inside about some punk kid saving Wolverine's sorry butt yet again, got me hooked on X-Men.
The coolest possible crossover would be Jubilee and Bumblebee.
