Keiji Inafune
Using features from two previous NES titles, as well as some new elements, series artist Keiji Inafune was happy with the flow from "Mega Man III" to "Mega Man IV". Inafune was also satisfied with how the Mega Man Killers Enker, Punk, and Ballade turned out. The artist had fun thinking up new ideas for Ballade's second form, which included the horns on his head turning up, larger bombs, and shades covering his eyes.
