Originally created as a household maintenance robot, along with his "sister" Roll, Rock lived a peaceful life. But, when mad scientist Dr. Wily reprogrammed several of Dr. Light's Robot Masters for evil, Rock's sense of justice took over, and he volunteered to be re-built as a war machine in order to defeat Dr. Wily's forces.
Dr. Light re-built Rock, and on that day, Mega Man was born!
