Stasis

So many questions and the answer is most likely cut content. Were the HBH's normal Egg Robos who were transformed by the Phantom Ruby? The online manual says Eggman dispatched the HBH's to retrieve the Ruby but clearly he sent normal Egg Robo's? Is it just Knuckles who fights the Heavy King? I thought it odd Sonic doesn't fight him at all in his story and then he's in a random form in the true final boss? Knuckles does but there's no special transformation in to what we see later. Regarding the true final boss, what mech is Eggman in? It looks like one he has previously battled in based on the damage and it being held together with tape. What is the importance of Little Planet? After being teleported there it somehow becomes a big part of the story that we don't see. Was the WIP animation of Sonic dodging the Heavy King scrapped? What was the Titanic Monarch? It just appears to be a big robot that does nothing and has no purpose? What flies out of the Titanic monarch and leave Little Planet at the end? I'm sure I've got more but this will suffice for now. Edit: just abused debug mode to get the Chaos Emeralds on no save mode to see if the HBH's can be killed in the final boss. Nope. Wonder why we can damage them though.
