See, I suffer from Idrewacoolrobot… itis. Since that comic, I was like, hey! That’s a cool looking robot! And so I used it as my avatar for an eternity. It’s not because it’s Michael 1an Black– I don’t think I even attempted to make it look like a caricature. I liked the design of the robot, as it was totally sweet.
Just wanted to dust off the cobwebs and see the bot in action again. So yeah, I guess it’s a retcon that he’s now Riboflavin’s sidekick, although your explanation about duplicate designs works out too. Yay fan theories!
