Cryopathy X was the same as any other sonic. He saved towns, rescued flicky's and stopped Dr.Ivo Robotniks evil master plans. However one day he had heard news of Dr.Robotnik engaging in another evil plan at a high mountain. Sonic had assumed it would be a quick in and out mission, little did he know the consequences of this quest. While on the mountain he fought Dr.Robotnik,but was outwitted and was trapped. He was left to die by Dr.Robotnik, with nothing but a poncho to keep himself warm. He later froze to death and died alone, everyone wondering where their hero had gone. Meanwhile sonic had perished, and in the afterlife he was greeted by a demonic being who convinced him that it was his friends fault that he had died. And like that he arose as a vengeful being seeking death to Eggman and everyone for in his words "I always gave, and yet as I let out my screams, no one came"
