PROTOMAN was built by Dr. Light and Dr. Wily as their first robotic achievement. Unfortunately, a glitch was present. When Dr. Light offered to repair it for Proto Man, he refused and ran away from the lab. He wandered on his own during the first events of his younger brother robot Mega Man's life, but was found after Mega had defeated Wily a second time. Wily found and repaired Proto Man, gaining the robot's alleigance from him. Proto Man still did not care to be kept under the boundries of one person, but he payed back the favor to Dr. Wily by serving him. Despite this, he saved Wily's nemesis, his brother, when he was injured during a confrontation in Wily's lab. Later, Proto Man betrayed Wily by saving Kalinka Cossack, a young girl the mad doctor had kidnapped as leverage. This enraged Wily, and he attempted to frame Proto Man for kidnapping Dr. Light. Fortunately, Proto Man destroyed the imposter, and Mega Man triumphed once again. From then on Proto Man has been a free spirit, never committing to the side of Dr. Wily or Dr. Light, but rather pitching in to help Dr. Light and his brother Mega Man whenever he's needed.
