Super Sonic

Super Sonic is a super transformation of Sonic the Hedgehog, created by using the power of the Chaos Emeralds and the Power Rings.

First Transformation
Sonic the Hedgehog first transformed into Super Sonic when a rampaging robot known as the Universalamander ran havoc across Robotropolis and into the Great Forest. Realizing he was outmatched, Sonic quickly gathered the 7 Chaos Emeralds and 50 Power Rings needed to transform into Super Sonic. He quickly made short work of the roboticized beast, having quickly taken a shrinking device Rotor Walrus devised and shrank him to the point where he wasn't a threat anymore. (StH: #4)

Epic Battles
Though Chaos Emeralds would come into play in later stages, Sonic would not take this form again until Sonic and Sally discovered a hidden Zone near a special lake. Taking advantage of it, Knuckles, who had learned of this Zone through a special book, dove into the Zone, seeking to take its Emeralds and rings so that he could help keep the Floating Island airborne should something happen to the one Emerald on the island. Not wanting to be outdone, the two rivals went at it, both of them turning Super Sonic and Hyper Knuckles and destroying the Zone in their fight. (SvK)

When Mammoth Mogul stole Enerjak's power and became Master Mogul, it was Athair who allowed the two former rivals, as well as Tails, to take their Super forms to defeat the would-be tyrant and seal him within the Master Emerald. (StH: #56)

When Dr. Eggman, still as Robo-Robotnik, used a weapon to throw the citizens of Knothole in reverse due being caught in the 3-hour zone shift, Sonic strapped on a Super Emerald and raced across Mobius, taking his various transformed states until the beam struck him, the Super Emerald turning his quills dark blue, his head quills longer, giving him green eyes and adding buckles &amp; soles to his shoes. (StH: #72)

During the Chaos incident in Station Square, when Chaos absorbed the Chaos Emeralds to become Perfect Chaos, Sonic took the remains of that energy to become Super Sonic, using the aura of the Chaos energy to soothe the beast as Knuckles and the Freedom Fighters fought to help stop Chaos and save the citizens. (StH: #84)

Not long after, Sonic used his super form (Along with the help of Super Shadow) to stop the Space Colony ARK from crashing into Mobius. (SU: )

After the Xorda
When Sonic was tossed into space after the Xorda Attack on Mobius, a variation of Super Sonic was created and forced to do battle with the real Sonic. (StH: #126)

Super Sonic was not summoned again until The Great Harmony, when A.D.A.M. gathered all of the chaos emeralds from the universe. Sonic and A.D.A.M both decided to utilize their super forms to stop each other. While they fought, Super Shadow and Turbo Tails sent all of the Emeralds into the Zone of Silence. Then Tommy Turtle, whom A.D.A.M. had possessed, sacrificed himself to destroy A.D.A.M. despite Super Sonic's protests. (StH: #169)

Battle With Enerjak
Sonic transformed once again into Super Sonic during the return of Enerjak. Although this could have been prevented, Dr. Finitevus let Sonic transform as he expected the Hex he placed on the Master Emerald to corrupt Super Sonic as well, though, for unknown reasons, the Hex had no effect on Super Sonic. Following this, Super Sonic battled Enerjak until Locke sacrificed his life to remove the Hex, restoring Knuckles to normal. (StH: #183, #184)

Abilities
During his stage as the invincible Super Sonic, he can fly and his speed is increased to one of it's highest maximums. He is virtually invincible and can almost defeat anyone. Due to the fact that he obtains this form because of all Chaos Emeralds and Power Rings, his strength and other normal abilities might also, be increased exponentioally. He can also use his positive aura to turn people possessed by some evil force back to normal. (StH: #184)

Background Information
Sonic's first transformation into Super Sonic was seen as a special cheat for fans playing Sonic the Hedgehog 2. This can be seen due to the use of the Sonic 2 variation of the Special Stage and Sonic saying that he needed seven Chaos Emeralds and fifty Rings to do so (this issue also marked the first appearance of the Chaos Emeralds in the series).
