Nightmare Phenomenon

''"Nightmare" redirects here. For the MegaMan Battle Network series virus, see Nightmare (virus).''

The Nightmare Phenomenon is a phenomena caused by the Nightmares created by Gate in Mega Man X6, that affect Reploids' DNA data and even the environment. Gate was able to create this by analyzing a piece of Zero's DNA, found by him in the remains of Eurasia.

The Nightmare Virus is a specialized enemy that looks different from nearly every other enemy in Mega Man X6. The player gains Nightmare Souls (a bluish orb) by defeating the Nightmares. Also, they'll infect and take control of rescuable Reploids if given the chance, turning them into Mavericks. If the Nightmare Soul they leave when destroyed has not being collected by the player after a few seconds, the Nightmare Virus will reappear. Destroying them a second time will not yield a Soul orb.

There are also two Nightmare bosses: one Nightmare similar to Zero called the Zero Nightmare, and two giant Nightmare masses that are the first boss of the final stages called Nightmare Mother.

Nightmare Souls
Whenever the player defeats a Nightmare Virus in a level or defeats the Maverick at the end of a level they will receive a Nightmare Soul (Nightmares yield a blue Soul, worth 8 points, and Maverick bosses yield a green Soul, worth 200 points). The number of Nightmare Souls collected determines the Maverick Hunter rank of the character that took it and how many parts can be equipped by that character. After defeating the Zero Nightmare and High Max (or by simply waiting: if the player gets to a certain point of the game without beating the Zero Nightmare or High Max, they disappear), Dynamo will appear and challenge the player to a fight if they enter a hidden zone. Hitting Dynamo with his weakness (Rainy Turtloid's ability) will cause him to drop a green Nightmare Soul; this can be done up to three times per battle.

Zero Nightmare
The Zero Nightmare (ゼロ ナイトメア) is an off-colored (purple armor with teal eyes and purple hair) Nightmare similar to Zero created by Gate, through use of Zero's DNA. He is seemingly incomplete and mentally insane, one moment claiming that X has gone Maverick when he throws it in his face that he isn't the real Zero, then the next moment incoherently shouting out "BLUE LIGHT... MUST KILL!", among other phrases. He is the first boss of the hidden areas. His attacks and moves are similar to those of Zero in X5. When he is defeated, Zero will become a playable character. He is weak to the Z-Saber. The music in his battle is the same music featured during the X vs. Zero fight in X5.


 * An alternate unlockable color for Zero in Tatsunoko vs. Capcom bears a resemblance to Nightmare Zero, being purple, but with white hair and dark purple arms and legs. It doesn't completely look like it, but could be considered a Nightmare Zero tribute.

Nightmare Mother
The Nightmare Mother (ナイトメアマザー) is the boss of the first part of Gate's Lab, two giant masses of Nightmare DNA that spin through the room, stopping every so often to open their "eyes" to attack. Their only vulnerable area are their mechanical eyes, which are weak to the Metal Anchor or Rakukoujin.

Nightmare Virus
The Nightmare Virus (ナイトメア・ウィルス) is an enemy found in almost every stage (except the intro level and the first Secret Laboratory level). They can attack the player by shooting at them, or by getting close and touching them. If the player is playing on Xtreme difficulty, the virus can also disappear, reappear close to X or Zero, and charge at him. They leave behind Nightmare Souls when destroyed. If the player doesn't take the Nightmare Soul before it vanishes, the Nightmare Virus will regenerate, but only one time and it will not leave a Nightmare Soul when destroyed again.

If it's on the same screen with a Reploid in need of help, it will move in to try and possess them. If the Nightmare Virus is not destroyed or the Reploid is not rescued before the Nightmare Virus gets too close, the Reploid will turn Maverick (which somewhat resembles a zombie version of itself) and attack the player. If a Reploid holding an item is turned Maverick, the item will be lost forever. 

Nightmare Bug
Nightmare Bug is a bug enemy that flies near the player. They can only be destroyed by Yammar Option, but it is generally useless as more will always come. It appears in the stages of Commander Yammark, Shield Sheldon, and Blaze Heatnix. 

Nightmare Insect
Nightmare Insect (ナイトメア・インセクト) is a mantis enemy that appears in Commander Yammark's stage. If they are destroyed with any weapon other than the Yammar Option they will regenerate, leaving the player a quick chance to get by. 

Nightmare Pressure
Nightmare Pressure (ナイトメア・プレッシャー) is the sub-boss of Metal Shark Player's stage. Presumably, it's the core of the trash compactor that antagonizes the player throughout the whole stage. The compactor (but not the Boss) returns in Gate's stage if the player chooses Zero. 

Nightmare Snake
Nightmare Snake (ナイトメア・スネーク) is the name of five red Mechaniloid sub-bosses that appear in Blaze Heatnix's stage. They resemble a mythological creature known as Ouroboros, a snake that bites its own tail and thus making a circle. They can only be defeated by destroying the four green cores around their frame. They are weak to the weapon gained from Infinity Mijinion, Ray Arrow and Rekkouha, and X's Nova Strike (his Ultimate Armor's Giga Attack). A charged Metal Anchor can take out the sub-boss in one hit, given a bit of positioning and luck. This sub-boss is considered to be one of the most annoying in the whole X series as it appears one after another whenever they are defeated and when the player advances into another portion of the stage. It is also worth noting that on Easy Mode, this sub-boss does not shoot its projectiles from its cores. 

Hazards and other effects

 * Nightmare Cube: NightmareCubesMMX6.gif obstacle that appears in the stages of Metal Shark Player and Shield Sheldon. The red and brown ones can be destroyed with weapons gained from Ground Scaravich, Ground Dash and Sentsuizan, while the black and blue ones can only be pushed by these same attacks. Note that the red ones cause an explosion that can cause serious damage to the player when destroyed. For the cubes that cannot be destroyed whatsoever, blue cubes slide when struck while the black ones move a slight bit.


 * Nightmare Dark: A portion of the screen will become pitch-black, and visible/semi-visible portions will be moving in a pattern that greatly reduces visibility; increasing the difficulty of the stage by a sizable percent. This phenomenon happens in the stages of Commander Yammark and Rainy Turtloid.


 * Nightmare Fire: Nightmare_fire_sprite.gifng fire balls that appear in Blizzard Wolfang's and Infinity Mijinion's stages. Although it's mainly useless to do so, they can be destroyed by Magma Blade or Shoenzan.


 * Nightmare Ice: Ice that appears only in Metal Shark Player's stage. Some floors/surfaces are coated with ice and can be destroyed only with Ice Burst or Hyourouga.


 * Nightmare Iron: Iron blocks that appear in the stages of Blaze Heatnix, Ground Scaravich and Infinity Mijinion. They can only be destroyed using Metal Anchor/Rakukojin.Nightmare_iron_sprite.gif


 * Nightmare Laser: Lasers in Shield Sheldon's stage. They're needed to complete the puzzles there, using the rotating reflective panels. Nightmare_laser_sprite1.gif


 * Nightmare Mirror: A silouhette form of X or Zero that sometimes appears in Rainy Turtloid's and Blizzard Wolfang's stages. It will have the form of a purple Zero if the player is using X, and the form of a turquoise X with Zero. They are similar to the Zero Virus from X5.


 * Nightmare Rain: The acid rain in Rainy Turtloid's stage and Gate's stage if you chose X. It slowly drains the player's lifebar. They are often accompanied by platforms which recover health, weather control devices that are protected by shields, and cores that deactivate the shields.


 * Nightmare Random: Nightmare_random_sprite.gif and square rocks that appear in Ground Scaravich's stage and the 2nd of the final stages (where the player has to fight through two consecutive stages without resting). These seem to be the main enemies in this stage other than the totem poles and the Nightmare Viruses.
