A/N: Inspired by the IDW Comic of Sonic The Hedgehog, and Mixedfan8643's Sonic the Hedgehog fanfic, this story has come to be. I hope you enjoy, and please don't flame on me.
Prologue:
Before we begin the story, know first the past.
Long ago, before the era of Dr. Robotnik, there stood a city that unified two proud kingdoms; the Kingdom of Acorns and the Kingdom of Hedgehogs together. It was called Mobotropolis. It was a beautiful city of peace and prosperity, ruled by the House of Acorn and the Royal Hedgehogs respectively. Together, with their kind and wise ways, the two kingdoms and their rulers ruled in perfect harmony, which spread across all of Mobius. All but one.
One day, after the royal triplets of the hedgehogs were born, tragedy befell on the two kingdoms. From the Land of Darkness, the evil Dr. Robotnik rose with an army of robots with the goal to subjugate the world and turn it into his own personal empire, full of agony and terror. Kingdoms by kingdoms, Dr. Robotnik's reign of terror seemed unstoppable, and those who resisted, met a terrible price. In wasn't long before he reached Mobotropolis, and in a single battle, it became Robotroplis. The people have all became slaves to the evil doctor, while the aristocrats, whom were the source of Robotnik's money, were left in play. King Acorn disappeared, along with his royal wizard, his daughter was captured and became a robotic slave, while the Royal Hedgehogs, all went into hiding, in their own separate ways and a bounty was placed upon their heads. With almost all of Mobius under Robotnik's control, her kingdom lost, along with her dearest friends of the Acorn Kingdom, Queen Aleena sought out answers from the revered Oracle of Delphius.
The Oracle revealed to her of a prophecy. It is fated, that in a coming day, Dr. Robotnik, will be overthrown, his reign of terror will be brought to an end, on the day when Queen Aleena reunites with her children.
In order for the prophecy to be fullfilled, Queen Aleena, was forced to give up her children, each separated from the other, until the day when they will be ready to learn their destiny, and take the first step of their adventures, to find their mother, and defeat Dr. Robotnik.
But the prophecy also spoke of an omen. For only one of Queen Aleena's children can defeat Dr. Robotnik. This hedgehog, will either be the savior of Mobius, or it's destroyer. It begins, when two brothers engage in a fight of Light and Darkness, a battle that determines the fate of the world. The Prince of Mobius and the King of Thieves.
