  1. Zero

    Zero is a video game character present throughout the Mega Man franchise. First appearing in the 1993 game Mega Man X for the Super Nintendo, Zero has since been the star of the Mega Man Zero series and has played a supporting role in other game series such as the Mega Man ZX series. First developed by Keiji Inafune when he was attempting to create a new design for Mega Man for the X series, Zero was instead used as a secondary character. In the Zero series, which was developed by Inti Creates, Zero is the protagonist and had a change in his design, which was meant to create a more "human feel" to him. Zero has since played a minor role in the ZX series as Model Z. His inclusion in the Mega Man X series has generally received positive critical response from video games reviewers.
