Ultimate Armor

The Ultimate Armor is a secret armor for X that bestows the most all-around fighting power in any of the games in which it appears. Because it appears in so many games in the series, it has the most recurring traits of any of X's armors.

Mega Man X4-X6
In Mega Man X4, X5, and X6, the Ultimate Armor grants all of the abilities of the Fourth Armor, and appears as a modified version of that same armor. Its buster's charged shot is the plasma shot of the Fourth Armor, and its powerful Nova Strike can be performed an unlimited number of times.

In Mega Man X4, even if a code has been inputted, the armor must still be obtained through one of Dr. Light's hidden armor capsules (the easiest of which is in Web Spider's stage). Until then, X's secondary turquoise hue is changed to a lighter purple one, a tell-tale sign that the code has been entered correctly. In Mega Man X5 and X6, the armor will be equipped on X when starting a new game, as long as the code has been entered correctly.

Maverick Weapon usage while equipped with the Ultimate Armor varies from game to game: In Mega Man X4, this Armor grants X unlimited usage of Special Weapons in their normal shot forms, Weapon Energy will still be used whe Charged Shots are used. However, in Mega Man X5 and X6, this Armor will work like the other Armors used in their respective games with the maximum shot capacity of the Maverick Weapons that X can use are automatically increased by 50%.

However, in Mega Man X5, there is a way to receive the Ultimate Armor without using a code. In the third station of the Zero Virus stage, there is a vertical shaft that leads to a special armor capsule. Entering this capsule as normal X will grant him the Ultimate Armor.

Mega Man X8
In Mega Man X8, the Ultimate Armor may be unlocked through either a code, or by starting a new game from a save file that has been cleared while X is at 100%. In addition, X has to also obtain all 8 Armor Parts that forms the Icarus and Hermes Armors for the Armor to be available. Take note that the code option is available for the console version (PS2) of this game only and does no effect in its PC Version.

In this game, the Ultimate Armor appears to be a black version of the Neutral Armor, with its own violet glow. It is a separate option within the Neutral Armor selection, and thus cannot mix its parts with those of the Hermes and Icarus Armor. The most probable reason that a purple glow is used is that this Ultimate Armor fuses abilities of the game's two Armor Sets, Icarus (red) and Hermes (blue) into one single Armor, notably being Foot Parts U, which is the abilities of Foot Parts I (from Icarus Armor) and Foot Parts H (from Hermes Armor) fused into one single part.

In this game, the Ultimate Armor's buster retains the Plasma Shot of the Fourth Armor, and grants the protection of the Icarus Armor's body part, the Shoryuken (or Dragon Punch) ability from Mega Man X2, as well as the abilities of both boot parts from the same game. This Armor has one uncanny ability that other Ultimate Armors do not have - It grants X unlimited usage of all Special Weapons obtained by Maverick Bosses, including charged shots! This is different from what the Ultimate Armor in Mega Man X4 does in using weapon energy for charged shots only.

This version of the Ultimate Armor has a more limited but ultra-powerful Nova Strike, which is limited by its own weapon gauge. It will drain the entire energy gauge, but also has the quickest recharging rate, recharging the energy gauge competely in mere seconds. This version of the Nova Strike is more powerful when X's weapon gauge is augmented via Pallette's chip development. When used on a boss in Normal Mode or higher, it can reduce its health down to a single unit of life, but cannot kill unless used a second time due to the boss having to unleash an Overdrive Attack first. Also, if used on Sigma before he automatically grabs the character, it will only reduce his health enough to initiate that segment of the fight. The way X performs his Nova Strike in this armor resembles that of the Blade Armor's Mach Dash in Mega Man X6 covered in powerful destructive energy and can only dash left or right.

Mega Man X: Command Mission
In Mega Man X: Command Mission, the Ultimate Armor is X's second Hyper Mode, and is earned by defeating the boss Rafflesian.

A stark change in appearance from previous armors in terms of design, but the color-scheme is back to the white, blue, red, and disc-like object protrudes from his shoulders horizontally behind him. A large, green gem forms his chest, and a targeting display covers his left eye. Gatling batteries are on the front of his shoulders, and his arms change into a pair of large, pistol-like appendages from the elbow down. The legs and the top of the disc are also translucent. X's standard attack becomes a devastating beam attack fired from his chest, and his sub weapons are Impact Cannon and Strike Bullet. yellow detailing. X hovers perpetually in the air with this armor (presumably being too heavy to stand), and a large

X's Action Trigger in this Hyper Mode is still called the Nova Strike, but functions much the same as the Final Strike. The higher X's WE is when the move is started, the longer X has to attack enemies.

X4-X6

 * Foot Parts- Grants X the ability to air dash or hover in midair. Midair hovering time is decreased if X moves.
 * Body Parts- Reduces damage taken by X by 50%. Allows X to use a wider range Nova Strike that does not consume any weapon energy. It also covers more distance than its X4 counterpart. Note, however, that it does require X to touch solid ground/cling to a wall before it can be used again.
 * Arm Parts- Grants X the powerful Plasma Shot.
 * Head Parts- In X4, uncharged weapon usage was reduced to zero. In X5 and X6, this increases the maximum Special Weapon shot capacity by 50%, just like the Fourth, Falcon, and Blade Armor Helmets in their respective games.

X8

 * Foot Parts U - X's movement speed and jumping height will increase. He can also dash through enemies without damage, which is the combined abilities of Foot Parts H and I in the game's Hermes and Icarus Armors respectively.
 * Body Parts U - X will take half damage and will not be subjected to recoil from collisions with enemies/hazards. All HP damage will be converted to red bars which is recoverable while in reserve which is the same ability as Body Parts I. Also enables X to perform the Nova Strike that can annhilate enemies in one attack.
 * Arm Parts U - The X-Buster's fully-charged shot will be the Plasma Shot where it can cause multiple damage to an enemy when it is hit with the weapon. Weapon Energy usage for all Special Weapons (including their Charged Shots) will be reduced to zero.
 * Head Parts U - X can use the Shouryuken (uppercut) technique to attack enemies directly upward, similar to the Head Parts I but with a smaller attack width.

Trivia

 * In Mega Man X4, Dr. Light's Hologram mentions that the Ultimate Armor is incomplete and possesses potential risk to use. No problems are ever encountered during gameplay however.
 * The armor in X5 is a slightly different color than in X4. The legs are a lighter blue, more similar to his usual color, and the purple parts of his upper legs, arms, and waist is his usual cyan color instead. However If Zero is selected during the third Zero Virus stage in Mega Man X5, X will be equipped with the Ultimate Armor with the X4 palette, (and X4 special weapons) during their battle.
 * Coincidentally, the battle also sees the temporary return of X's Special Weapons from Mega Man X4, the game in which the Ultimate Armor debuted. The weapons that X uses in that battle are Frost Tower, Double Cyclone and Soul Body.


 * In Mega Man X6, the Ultimate Armor has a black color, however if the Buster is charged, the Ultimate Armor will resemble its original palette. The color scheme also found its way into the Ultimate Armor used in Mega Man X8, albeit with the Neutral Armor as its design basis instead.


 * The Ultimate Armor's Nova Strike is one of two that is immediately available at the start of the game (in this case, X5 after entering the code). The other is the Giga Attack of the Falcon Armor, one game later.


 * Unlike any other armor set, the Ultimate Armor in every game has had several transparent parts, revealing X's inner workings.


 * During the first selling of Rockman X4 for the both Play Station and Sega Saturn system, Capcom included a Special Limited Pack containing an X constructible model toy, with his Ultimate Armor version.


 * Zero was originally planned to have his own Ultimate Armor alongside X in Mega Man X4, but it was replaced with Black Zero. The designer of Zero's Ultimate Armor hinted that his ultimate armor had to do with his connection to Dr. Wily, but stopped himself before he could reveal any more and instead supplied the design.
 * X makes use of his Ultimate Armor during the end of his finishing move in Project X Zone.
