Tails is really RoyaltyIn part two of the Quest for The Chaos Emeralds saga, Merlin tells Robotnik that in order to use the emerald he must become King. Tails, however, was able to activate it and gain a Heroic Build without getting the crown. The reason? The King's daughter married a vulpine nobleman, with Gender Equals Breed being in effect, making Tails a decendent of Adventures of Sonic the Hedgehog's King Arthur. His past before meeting Sonic was never fully explored, so it's possible that he's the long lost heir to the throne.

They aren't really speaking EnglishSee this scene from Tails's Tale. Look at the obvoiusly non-English writing on the monitor.
Grounder is a prototype version of the Bouncer Big Daddy.They both have drill hands. That's about it.
Had the series continued, Scratch, Grounder, and Coconuts would have been shown to be Minions With Fs In Evil (or even more blatantly if they were already) and eventually make Heel Face Turns.Would it be that surprising?
