There’s not a whole lot to report about this particular alternate universe version of Bob. He gets maybe ten panels in an issue of Spider-Man Loves Mary Jane, but hey, that’s more than the main version of Bob gets in some years. I can work with it.
He’s got the basic outfit and board that makes a Rocket Racer (though it is noteworthy that it is a wheel-less model of the board) and uses it to rob folks until Spider-Man stops him. Not much else to say about the events we witness.
I’ll note this: He’s not picking out the rich or the corporate as targets in particular, he’s just robbing people on the street who happen to have a purse or something else that he can easily grab. He also isn’t seen shooting mini-rockets and he definitely doesn’t have the magnetic clams that connect his feet to his board, because Spider-Man defeats him just by pulling him off the board with a web. I have to assume, then, that this is very early in this Bob’s career and he’s just getting started. If anything differentiates this Rocket Racer from others we’ve seen, it’s that’s he’s lower stakes. Smaller scale weaponry and pettier crimes.
