He had gone too far this time, Eggman really went too far this time. His usual style of robot building was abandoned, replaced for something more physical. This in itself wasn't all surprising seeing as roboticization while the worst he had come up with was something capable of being reversed. The man was a target for most if not all worldly destruction all which he was usually able to stop before it was able to become life-threatening to others. Not this time.
It was a weapon, yes, but its uses were something from nightmares. He watched the beam meant for him shocking his anti-counter, Scourges torturous screams during left Sonic horror-stricken. Lapsed in all movement and paused in thought as he processes what was happening. He had just witnessed Eggman's newest invention forcibly separate Scourges chaos signature (soul) from his body, leaving an empty shell to collapse to the ground. Once the beam offered but faint rays of its former self Sonic was snapped from his moment of silence then took action. Avoiding the problem that was Scourges body he defeated the machine and Eggman escaped. Sonic approached the body.
Calling Tails, he stepped towards the limped figure. A sudden awareness of being watched had Sonic check his surroundings. Quills perked he stood in a fighter's stance inspecting the area with suspicion; nothing of this after a few minutes though the sensation remained. He continued to examine the external environment while making his descent towards the body. A quick look around as he stood aside the body he hurriedly crouching next to the unconscious being, ready to pick up the other when pain erupted. Starting from the fingers which touched the body and rippling throughout his body an unbearable pain tore through his body. His head caught the worst of it sending waves of agony through his being, he screamed in pure anguish. It felt as though his own chaos signature was being forced aside as another entered; it was an intrusive feeling. Minutes would pass before the pain would stop and he'd welcome the pitch black void of unconsciousness and pass out.
He awoke in Tails lab, later to be informed as to what had resulted. Two signatures were read to be occupying his body, the who remained a mystery to the kit. A chuckling followed seconds later, Sonic looked around to find its source. Scourges body lied aside his own on a parallel cot though he was unconscious, the roughened vocals continued as its chuckled turned to laughter as Sonic searched for the voice's origin. Then realization came across his face a just as the chuckling inside diffused.
"Heh, ain't that about a bitch, huh Sonic?"
