Although originally the names "Mighty Kid", "Knuckle Kid", and "Rainbow Battle Kid" were proposed, Capcom eventually settled on "Rockman" as Mega Man's Japanese moniker. The word "Rock" in Rockman is a reference to the music genre rock and roll, and is meant to work in tandem with his sister robot, Roll. However, Capcom Consumer Products Division president Joe Morici changed the name from Rockman to Mega Man because he felt "The title was horrible."[6] In addition, the original Mega Man titles intentionally incorporated a "Rock, Paper, Scissors" gameplay mechanic into defeating certain enemies.[3][7] The pixel art for the character was created by the designer of the original game in the series, Akira Kitamura (credited under the pseudonym "A.K"),[8] and later turned into a refined illustration by Keiji Inafune.[2][9][10] Kitamura originally intended Mega Man to be colored white, but instead settled on blue to make his animations more clear. Mega Man's design had a lot of little influences from various manga, anime, and tokusatsu shows, specifically Ninja Captor.[11]
