A prototype Robot Master built by Dr. Light, Blues is kind of like Mega Man’s secret older brother. Plagued with hardware failure, Blues ran away for fear of the repairs changing his personality. Dr. Wily found and repaired a near-death Blues, transforming him into Proto Man. Still extremely independent, he’s become a rival to Mega Man who knows when to put their differences aside for the greater good. He appears alongside the other Mega Legends to help during Mega Man's Final Smash.
