In the American Mega Man TV series from Ruby-Spears, both Dr. Light and Dr. Wily created a red robot prototype. When the robot malfunctioned, Light asked Wily to destroy the plans and start over, but Wily stole the plans and used them to create Proto Man. Because of this, Proto Man is an evil robot that works for him. He has an intense rivalry with his "brother" Mega Man, wanting to be the one to defeat him, even if that means ruining Wily's plans to make sure he will be the one to get Mega Man. He considers Roll his sister as well, but although Mega Man agrees they are brothers and has admitted to wanting a friendship with him, Roll doesn't consider him her brother. Unlike his video game counterpart, Proto Man is sarcastic and prone to making light of Wily's failures, frequently showing a lack of respect for his creator despite serving him without question.
