-1Chapter 24: Vengeance of a Warrior

Everybody turned to see who had spoken, and as the red and black hedgehog slowly walked fourth, everybody was speechless. He walked slowly and picked up the Chaos Emerald from Espio's grip. He raised it above his head and chanted something, and before anybody knew it, small rays of light were entering Sonic's body, restoring him back to life.
"H-how…you're dead!" Jet shrieked.
Shadow placed the Chaos Emerald on the ground gently, and helped Sonic to his feet. When Sonic regained his senses, his eyes widened so much that it almost completely covered his face, "Sh-Shadow…You're alive!" he said eagerly and his heart rose to new heights.
"Yes, but there's no time to explain now…I will do that in time, but now I must take care of some old business," Shadow stated quietly, staring up at the now half-metal Spike.
Spike leapt to the ground and scowled, "I thought you were dead," he said truthfully.
Shadow forced a laugh, "I told you, you didn't win that day, now I'm going to show you my real power!" he roared, grabbing the Chaos Emerald.
"What's this?" Spike asked curiously.
"CHAOS COMMAND!" Shadow roared furiously, and the ground started shaking. Shadow looked at Sonic and his friends, "You must leave now!" he ordered.
Sonic and his friends did just that, and as the observed the battle from a small cavern, they watched as Shadow's entire body glowed red, "How'd he do it?" Wave asked.
"I think it had something to do with the Chaos Emerald," Sonic responded, "but I'm not entirely sure yet."

Shadow bent his arms at 90 degree angles and held them close to his body, and bent his knees as he started to hover above the ground, the earth still shaking.
Spike crossed his arms, and activated his hover boots, observing Shadow very carefully as if he were expecting something great.
"CHAOS COMMAND FIRE!" Shadow screamed, and a red barrier circled Shadow, and then shrank down inside of his body.
Shadow then put the bottom of his palms together and opened his hands, so that his palms were still aiming at Spike, and a small glowing sphere appeared in his hands.
The red glowing sphere grew slightly bigger and Shadow unbent his elbows and stuck his hands straight out, and an enormous beam came shooting out of the much smaller sphere. The beam completely engulfed Spike, and the mountain behind him crumbled.
As the smoke cleared, Spike stood no more. All that remained was a small mechanical finger, and a scanner that was once in his left eye. Shadow stomped down on his mechanical body parts, in his heart finishing the job. He stared out into the sky, "My vengeance is fulfilled," he said so quietly that it seemed he was talking to himself.
Shadow turned around and slowly walked towards Sonic's group, ready to explain his amazing return.
