Rockman Complete Works: Rockman 4 - Aratanaru Yabou!!

A mysterious Russian scientist named Dr. Cossack has unleashed an army of robots on eight cities, claiming an intention to dominate the world. Dr. Light deploys Mega Man — equipped with the new Mega Buster upgrade and a support robot named Eddie — to defeat Cossack's eight Robot Masters: Toad Man, Bright Man, Pharaoh Man, Ring Man, Dust Man, Skull Man, Dive Man, and Drill Man. Reaching Cossack's icy fortress afterward, Mega Man's battle is interrupted by Proto Man, who arrives with Cossack's daughter Kalinka. She reveals that Dr. Wily had kidnapped her to force her father's cooperation. Wily steps out of the shadows, furious at the exposure. Mega Man pursues him to the Wily Castle, which begins to collapse; he escapes by train, greeted at home by Roll and Rush.
