23rd Oct: It's time for the Second TV Tropes Halloween Avatar Contest! Details here
The Majority of this Sonic Cartoon is set in an alternate-dimension or alternate-level MobiusGiven that since the first two Sonic games that it has been possible for Sonic and Tails to warp between dimensions using a combination of ring orbs and ring-gateway devices to get all seven Chaos Emeralds, it's plausible to think that the majority of the Adventures of Sonic the Hedgehog episodes take place in a dimension between dimensions where the sky and land are a different colour pallet from their regular dimension in regular Mobius. Either that, or it is actually mostly set in underground Mobius where many different and strange beings have lived and 'evolved' over the future years that Sonic and Co. are said to be set in in most other media.
Tails is really RoyaltyIn part two of the Quest for The Chaos Emeralds saga, Merlynx 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 Arfur. His past before meeting Sonic was never fully explored, so it's possible that he's the long lost heir to the throne.
Sonic actually had no idea what he was actually talking about during his Sonic Sez segment on 'Touching'Depending on the show's in-universe rules, It turns out that when Sonic had been called out again to film his next Sonic Sez PSA segment; -in part because he's still around the age of 11- the producers of the segment found that they could get the young Superhero to touch on this sort of subject by flat out lying to Sonic that it was a moral segment on the topic of bullying rather than unwarranted harassment as it turns out to be.
This series is canon to the gamesThe show takes place between Sonic 4 and Sonic Unleashed. And going by the above...
The series takes place after Sonic SatAMWhere the Freedom Fighters have disbanded, and Dr. Robotnik never fully recovered from his Villainous Breakdown at the end of the last episode.
The series takes place before Sonic SatAMDr. Robotnik had a From Nobody to Nightmare moment, and started taking his hatred of Sonic to new levels, taking over the world.
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.
Grounder, Coconuts and Scratch are actually robotic Alternate Universe Versions of Ed, Edd n Eddy respectivelyScratch is the super squad's idealistic high-voiced team leader and lead scam- err... trap artist.
Grounder is the big doofus with a will to work, but whose low intelligence will turn out to be the squad's undoing.
Coconuts is the intelligent but also weakest and most ill-fated of the group who will very often be seen cleaning up the place in the lure of his piers.
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?
The Super Genesis Wave has rewritten the Adventures of Sonic the Hedgehog universe into a world similar to the video games but with some of the cartoon's elements intact.
