Black Zero

The Zero Armor, nicknamed the Black Zero or False Zero, is similar to the Ultimate Armor in that it is usually accessible by a secret code. The armor is a reference to Mega Man X2, where if all three Zero Parts are collected, a fake Zero appears in Sigma's Fortress with black-hued armor. This armor is never actually named in-game, and cannot be unequipped once received.

The effects of the Zero Armor are not consistent throughout the games it appears in. In its first appearance in X4, it appears to be just a facelift. In X5 and X6, it enhances Zero's defense and saber power. In X8, it upgrades Zero's dash, and may or may not increase his defense and saber power.

In Mega Man X5, there is a way to receive the Zero Armor without using a code. In the third station of Sigma's Fortress, there is a vertical shaft that leads to a capsule. Enter the capsule as Zero to gain the Zero Armor.

Refer to the table below for codes used to gain use of the Zero Armor. The codes are listed with the button pressed and the number of times pressed next to it. In Mega Man X4 and X5, highlight Zero on the Character Select screen and enter the codes. In Mega Man X6 and X8, highlight Game Start, complete the sequence of buttons, and press Start.
