Premiering as the deuteragonist of the Mega Man X series, Maverick Hunter Zero is at the top of his game. Cool and collected, he provides a sturdy balance to his partner X's bottomless will and strong sense of justice.

In Mega Man Xtreme, Zero sent X into the Mother Computer to fend off digital Maverick attacks. While he was stuck battling Mavericks in the real world, X could call upon combat data based on him to perform a special attack.
