Protoman is known for his dark sunglasses and yellow scarf. He also announces his presence by whistling his theme song. An imperfection in his neural network was later discovered by Dr. Light that gave Protoman a unique free will, but it would also run down his systems and cause irreparable damage over time. Protoman chose to leave the glitch unperfected, and lives his days how he wishes, and probably solitary.
*NOTE: Protoman's original name (in Japan) is Blues.
From Megaman 3, where the character Break Man fights you multiple times, but turns out to be your brother who is helping you train for the final fight with Wily.
Common Protomen are siblings, Teachers, and Parents.
