Despite being created by the evil Dr. Wily, Zero fights for good and righteous causes throughout his robotic existence. 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. Zero's model used in Marvel VS Capcom 3 is the one from the Megaman X series, not be confused with his look in his own series, the Megaman Zero series. He is equipped with a buster in his right arm that shoots projectiles with different amounts of power depending on how much the shot was charged. This weapon is called his Z-Buster. Zero's main weapon is his Z-Saber, a green sword based on energy.
