This transformation exists primarily or exclusively within the Pre-Super Genesis Wave continuity. Information in this article may not be canonical to the storyline of the games or any other Sonic continuity.
Shadow first reached this transformation when he allied himself with Super Sonic to stop the Biolizard from destroying Mobius with the Space Colony ARK. He took this form again when the Bem rescued him from the previously mentioned incident and provided him with enough power in order to combat the approaching Xorda. Super Shadow proved unprepared for the Xorda attack however and was sent plummeting towards Mobius.
Shadow went on to achieve his super transformation once again. However this time he was forced into it in a device of A.D.A.M.'s creation. In his super form, his enhanced Chaos Control assisted in pulling all of the Chaos Emeralds in the universe towards Mobius to use their incredible powers. After being released from captivity by Dr. Eggman, Super Shadow used his Chaos Control to aid Turbo Tails and sent all of the Chaos Emeralds into the Zone of Silence, thus ending A.D.A.M.'s plans.
