The concept of Zero starring in his own series was proposed by Inafune. Inafune proposed that Zero star in his own series, and planned to go forward with the idea at the end of "Mega Man X5". However, he was unable to after Capcom announced another "Mega Man" title without his involvement. Designed by Toru Nakayama of Inti Creates, Zero was meant to have a more "human feel" rather than the complete "mechanical feel" of the "X" series. Nakayama wanted the public to recognize that this series was different from the "X" series. Since Capcom wanted Zero's general structure to be the same, Inti-Creates concentrated on how different they could make him, rather than how similar. Zero's depiction in the series was intended to be morally ambiguous and depend on the perspective, appearing as a hero from one point of view and a terrorist from another.
