Once that final power-up chip is redeemed, Black Zero will be made available immediately for selection. In Mega Man X8, the player must redeem all of Zero's available power-up chips and complete the game to save into a New Game Plus, by which the final power-up chip will be made available ( Sigma Blade).The Black Zero's enhanced saber can destroy energy shots (even Ultimate Armor X's Charge Shot). Zero is welcome to either take it or leave it, though Zero claims he doesn't need any upgrades. Light, he (Light) says he wasn't able to create any armor for Zero, but he is able to enhance his abilities. According to the conversation that Zero has with Dr. Enter the capsule as Zero to enhance him into Black Zero (alternately, X can enter a similar capsule in the same area to obtain his Ultimate Armor). In the third Zero Space stage, there is a vertical shaft that leads to a capsule. In Mega Man X5, there is a way to receive the Black Zero enhancement without using a code.LB, LB, RB, RB, LB, LB, LB, LB ( Xbox One/Steam) LB, LB, LB, RT ( Xbox One/Steam with Controller)
While there is no way of knowing if the code is completed in X4 until the opening stage is accessed, in X5 and X6 a sound clip is heard if entered correctly, while a sound clip of Zero is used for X8.
In Mega Man X6 and X8, highlight Game Start, complete the sequence of buttons, and press Start. In Mega Man X4 and X5, highlight Zero on the Character Select screen and enter the codes. The codes are listed with the button pressed and the number of times pressed next to it. Refer to the table below for codes used to gain use of Black Zero. In Mega Man X: Command Mission, it doubles his attack power, increases his speed by 1.5, bumps up his WE gain per turn by 25% and cuts his fire damage to 75%, but has an extremely short number of usable turns without using Build Hypers.In Mega Man X8, it doubles Zero's dash speed and distance, doubles the damage power of his weapons, but halves his defense as a tradeoff.This replacement is due to the game's absence of Sigma Virus and Zero Virus drones.
In Mega Man X6, Black Zero's Virus Buster is replaced by Z-Saber Plus (damage per Z-Saber slash is increased).In Mega Man X5, Black Zero has Shock Buffer (Damage and stun are reduced by half), Shot Eraser (Z-Saber can destroy enemies' energy shots akin to Tenkuuha) and Virus Buster (Z-Saber can destroy Sigma Virus drones).However, three power-up parts will be automatically added for the black armor in both games, even if the player has not obtained them yet: In Mega Man X5 and X6, it enhances his defense and saber power, and also adds 50% to Zero's weapon energy, like all of X's armors in these games do. In its first appearance in Mega Man X4, it is simply aesthetic and has no effect on his combat abilities. The effects of the Black Zero enhancement are not consistent throughout the games it appears in.
