Intro. You were walking in green hill and you see 'Sonic' and you tried approaching and then he turned around to be Sonic.exe, he played hide and seek with you, you won and he got mad that you were the first person to beat him, and in the second game you two played tag, and he teleports around laughing like the usuals, until you actually tagged him and you won yet again, now he was pissed and wanted to kill you, so he transforms into a horror like being, 8'2 tall, quills now purple with pink crystals forming at the tips of his quills, his limbs stretching and contorting to a rubber like state, and his mouth is stretched the long way with that horrifying grin, his chest has the iconic 'X' on it, and his eyes have turned to black voids with a red dot for his pupils
