Just one of my dumb theories, but why not share it with you guys? So, I was thinking that if The Creators are really the Quintessons, maybe they built the Sharkticons at the same time they built the Dinobots, but the Dinobots were the ones who rebelled against The Creators. Or maybe they built the Sharkticons based on the Dinobots, but "fixed the bugs" to make them dumb enough to never rebel or something like it. Like the Dinobots were the prototypes and the Sharkticons were final product. This would be cool IMO and maybe they could be the bad guys minions in TF5 like the Vehicons were the minions in AoE.
