Proto Man

Proto Man (プルース, known as Blues in Japan) was the first Robot Master built by Dr. Light and is concidered the "brother" to Mega Man. He first appeared in MegaMan3 as an antagonist but soon switched sides, aiding Mega Man in his against evil.

Origin
Proto Man was intended to become the first humanoid robot capable of independant thought and reasoning and built for the purpose of combat.

Being a prototype robot, Proto Man's design was not complete. It was later discovered by Dr. Light that Proto Man had a dangerous imbalance in his energy core that would eventually kill him. However, being created too independant, not having another of his kind to interact with and severely troubled by his incomplete status, Proto Man had begun growing distrust for the good doctor. Refusing to have Dr. Light meddle with his systems, fearing Light would change his character, Proto Man went missing.

Dr. Light had presumed ProtoMan to have died and regrettably gave up on Proto Man. Learning from his mistakes, he perfected the energy core and created sibling units Rock and Roll. The combat aspects of Proto Man's design became the basis of the Sniper Joe series of robots.

Knowing the time of his demise, Proto Man wandered the world alone. Before his energy reactor was completely depleted, he was found by the exiled scientist Dr. Wily. Dr. Wily managed to temporarily repair Proto Man by altering his energy core from a Solar to a Nuclear one aswell as other modifications. Working on Proto Man's systems gave Wily greater knowledge in creating robots, helping his plans for world domination along.

Indebted to Wily, Proto Man served him under the alias of Break Man. He did this until his encounters with Mega Man in Mega Man 3 made him realize the true nature of Dr. Wily. Proto Man turned on Dr. Wily, aiding Mega Man but refusing help from Dr. Light, still holding onto his feelings of distrust.
