Sonya is a boy and Manic is a girl.
The Oracle set it all up for his own twisted amusementAleena wouldn't have abandoned and split up her kids at all if he hadn't just appeared one night and told her that they had to be split up to reunite to form the Council of Four to overthrow Robotnik.
The show wasn't originally going to be a Sonic cartoonSimple, and it makes sense, given how different it is from other Sonic media. Early in development, it was originally going to be a wholly original cartoon, only to be Re-Tooled into a sonic show. It is entirely possible that originally the heroes were just a Brother-Sister Team consisting of the characters who became Manic and Sonia, given Sonic's personality is still relatively intact. Robotnik was likely some generic evil overlord who the two main characters would use the Power of Rock to fight.
This Series is a Story made by Nack the Weasel.Simply put, Nack, bored one day when no one hired him that day, decided to make a comic on how Sonic would be if he had siblings, was a prince like Princess Sally, had a magical instrument, had two childhood hunters growing up be hired by Robotnik to chase after him, and made it intentionally as bad as it was just to ridicule while making fun of Sonic, due to his hatred of the blue hedgehog that outsmarted him and stole his emeralds. He of course left out all, but Robotnik and Knuckles within the story and tried to make the plot silly and weird.
Dingo is Sleet's golemBy definition, a golem is an artificial being brought to life by science or magic, but in slang it is used for someone who is stupid, literally coming from the Yiddish word meaning 'slow'. Golems are also known for being hostile, but nevertheless faithful to whom they serve (Chaos Emerald Arc, and Dingo's constant panic throughout the show that can be summed up in the sentence 'What am I gonna tell Sleet?'). Golems are also known for speaking after their master does (here, it's for laughs, but it is true to a basic golem formula.) Dingo's shape-shifting ability also does not come naturally, it comes with a remote control, something that is also mechanically made. Note that Dingo doesn't have control over what he changes into; he changes into whatever Sleet wants him to. He also has a very basic, limited command code, most of it being used on his ability to shape shift. He probably can't do math, but he can swim, drive their car, and is capable of recognizing faces. His disobedience quickly changes back to his humbler state of being after a rebellious streak, possibly because he was programmed to call his master by his first name and to have some semblance of a personality as to not be conspicuous in public, even resulting in basic emotions. Even in the parallel Ancient Rome world, Dingo still serves under Sleet.
The events of the show were removed from time along with the events of Sonic the Hedgehog (2006).
