Sonic woke up in the middle of a damaged forest, feeling tired for reasons that were beyond him - he got up and looked around, while trying to remember what had happened. "Ugh, my head hurts..." he commented, taking a good look at himself. He was covered in blood, and his clothes were slightly damaged but he was fine otherwise. He then spotted a ship in the distance.

Vague memories about his friends and Eggman arose in his mind. They showed expressions like fear, anger, despair, feelings like that. The hedgehog remembered how similar the circumstances were to when... he…

A chill went up his spine, remembering how many times he had found himself in this kind of situation before. "I hope I didn't do anything too bad this time..." And with that, he raced to where the ship was.

Along the way he spotted trees that had been torn up, rocks that were broken open, and marks along the ground. Suddenly, he was running past dead. Worst came to worst in his mind, but he continued. "Huh, am I..." He looked down as he ran. "Faster than before? I've gotta figure that out later, too." He continued onward to the ship. Once he arrived, he saw the state of disarray it was in - Standing close to a giant crater, he stepped closer. What he saw next horrified him.

It was Shadow... what was left of him, anyways. He was dead, his body was literally ripped in two, with his blood spilled across the ground. "O-Oh, no, no, no, no!" He shook in fear as pieces of memories about what he'd done came flooding back.

...Suddenly, a bright red flash lit up the entire forest, toppling dozens of trees and damaging the ship nearby. Once the dust cleared, the demon dropped the two halves of the black hedgehog to the ground...

"M-M-Maybe someone survived! I need to find them!" he stammered, glancing at the ship. "Maybe they're on the ship?" He rammed the door open and scrambled inside, before scouting around for survivors. Then he found the first corpse, being Knuckles' head, while his body was absent.

...Demon Sonic laughed at Knuckles pathetic attempts to hurt him - even with his super form, he couldn't even make him flinch...

"...What's wrong knucklehead? Weren't you supposed to be the strongest?" The demon mocked him, then stopped a comet punch from the echidna. He let go of his hand only for Knuckles to attack him with everything that he had... Only for him to stop Knuckles again with one hand - the explosion didn't even bother the hedgehog. Already bored with the echidna, Sonic choose to finish him off by generating a sword of chaos energy - and he sliced Knuckles' head off , as the sword vaporized his body...

Horrified, Sonic ran off to try to find another one of his friends. He ended up finding Amy's body, with her arms ripped off and a hole through where her heart should be - another memory came.

...Super Amy slammed her Piko Piko Hammer as hard as she could against the demon. Even though she saw that it got no reaction, she tried several times to no effect. After a moment or two, the demon grabbed her arms and proceeded to kick her in the torso, ripping her arms out of their sockets in the process. He gazed at her as she powered down, failing to hold back the pain as tears swelled in her eyes. Sonic, without a second thought, shot a finger beam through her heart, killing her instantly...

Sonic was desperate now. With each body he found, he was afraid he'd killed them all. He continued, wondering what had happened to Eggman.

...The doctor tried to maintain his composure as the hypercharged demon marched towards him. He put his hand out in front of him, gathering chaos energy. "Bye bye, doctor~" He proceeded to blast Eggman into oblivion...

That solved one mystery, but he still needed to find survivors. But no matter where he went, he found nothing but corpses, or what remained of them.

...The demon shot eye lasers through Rouge's wings, destroying them and part of her body...

...Sonic barely even put in effort to destroy Omega, firing a weak chaos blast to obliterate him...

Sonic just couldn't find survivors anyway on the ship. It wasn't until he saw the last body that he just...broke.

It was the body of Tails, his closest friend, lying lifeless on the ground. He approached it slowly until he was right next to the body, then dropped to his knees as he began to remember what he had done to him.

...Tails was paralyzed with fear when Sonic, whom he had seen as a father figure, was now unrecognizable to him, and was stepping towards him... "Hello, Tails~" The demon spoke in a chilling tone, and he proceeded to grab Tails by his... tails.

"Sonic... P-please, no!" The child was pleading, his voice filled with fear. "Sonic, yes~!" the demon said, laughing. He then ripped both of his tails off of his body without hesitation. Tails screamed in pain as blood poured from the fresh wound, trying to crawl away before being grabbed by the neck. He could only cry as the demon put a hand on his stomach, gathering chaos energy. "Goodnight, Tails~" He then unleashed a chaos blast, ending Tail's life in a second.

After that, all Sonic could do was cry. He was alone, sobbing on the body of his best friend.
