After you managed shooting on the mouthless Sonic in the stomach, he dies, and his body fades.

Suddendly he respawns and jumps out of a monitor, but he's not the same "Sonic" anymore. He was with red dots on his eyes, and with sharp teeth on his mouth.

"YOU CAN'T KILL ME, DORK, IM STILL ALIVE."

He said, in a annoyed and glitched tone, he seems like he not liked when you shooted him in the stomach.
