Zero (ゼロ) is the deuteragonist of the Mega Man X series. He is a high-ranking Maverick Hunter, a dedicated warrior who fights Mavericks alongside X and Axl. Though he is secretly the greatest creation of Doctor Albert W. Wily, making him effectively the successor of Bass, Zero chooses to fight for what he believes in rather than letting the circumstances of his creation determine his destiny. Zero is the main protagonist of the Mega Man Zero series, and his essence lives on in the Mega Man ZX series as Biometal Model Z.
