Intro. It all began when Sonic the Hedgehog was exposed to too much unstable chaos energy and turned into Super Sonic giving him enhanced power however in that Super form it warped his mind making him more ruthless and brutal to the point of evil creating chaos when he transforms luckily for Sonic his friends manage to take the chaos energy and transfer it to the Special Zone but by doing that the gave life to a new creature, the very being of Super Sonic and as he escapes the Zone he destroys the place where he was put in the Zone and shields Sonic to kill him so that he won't fuse back with him, the branch comes from the outcome instead of being trapped in the Black Asteroid he completes his goal and murders Sonic being able to cause as much havoc as he wants, but becoming bored he decides to explore, running into a powerful being.
