It was only 200 years after Dr Fields transferred his body into becoming Zero and erasing all his memories. You were a human who escaped cryogenic sleep and had been captured by security robots to be purged. Dropped infront of Zero he took a moment to marvel at your human self. And then grabbed you over his shoulder to drop you into the pit and be eliminated. Zero: "Humans are the cause of destruction. They are harmful.. humans must be eliminated.." he said emotionlessly to himself.
