Zero

Zero's History

Origin

Zero was created by the late Dr. Albert Wily sometime in the early twenty-first century. Wily alluded to him during Bass's ending in Mega Man: The Power Battle, where he mentioned he was developing a robot that will blow away both Mega Man and Bass. Schematic blueprints of his body were seen during Bass's ending in Mega Man 2: The Power Fighters. Learning from his past mistakes, including the accidental creation of Bassnium and his construction of Bass and King, Wily constructed Zero as a far more advanced robot than anything he had ever built before, with a power level far superior to that of Bass or Mega Man using Proto Man as reference for Zero's design. He also presumably began to create the Maverick Virus around this time. Wily even dubbed Zero his "greatest masterpiece". Zero contained a flaw in his cognitive program that made him violent and unwilling to obey instructions. Because of this, Wily decided to seal him in a capsule. Decades later, in the early twenty-second century, his hiding place was found by a group of Reploids prior to the first Mega Man X game.

Once awakened by this group, Zero destroyed them, as well as any intruders who would dare enter Wily's lair. Labeled a Maverick (by the definition of being a threat to humans), Zero was later cornered by Maverick Hunters inside an unknown facility, and Zero destroyed Garma's unit. Not wanting to get any more comrades endangered by the powerful enigmatic Maverick, then-Hunter Commander Sigma himself challenged the red Maverick in a one-on-one battle. Even though Zero eventually gained the upper hand during the battle, Sigma was able to defeat the red Maverick after the gem on Zero's head began to glow with a 'W' symbol, apparently causing Zero great pain.

Sigma punched this crystal, shattering it and defeating Zero, and Sigma was infected by Zero's Maverick Virus. Zero was then brought to Dr. Cain, who analyzed him. After that, he recovered from his battle with Sigma and was placed under Sigma's watch. Zero did not show any more signs of Maverick behavior and was enlisted into the Maverick Hunters' 17th Elite Unit.

The Day of Σ

As part of the 17th Elite Unit, Zero became an excellent Maverick Hunter and was soon ranked A-Class, the highest rank the Maverick Hunters had to offer at that point in time. It was during that time in which he met X for the first time who was also part of the 17th Unit, even though he was only ranked B-Class due to his hesitation on the battlefield. The two became friends and partners and worked together whenever they could. Zero soon became somewhat of a mentor to X.

Soon afterward, a series of Mechaniloids going berserk occurred in Abel City, the city in which the Hunter Base at that point was located. During the course of the investigation, it was Zero who eventually uncovered the identity of the person responsible for the attacks, which was none other than Sigma himself. Zero realized this after analyzing various locations which were seemly connected to the attacks, and by looking over the bodies of defeated Reploids, which were all taken down with a single blow directed at a weak spot. There had been only a very few numbers of Reploids with such perfect skills, including Sigma. The blows that the defeated Reploids had taken was caused by a beam saber, and not by range-weapons, which ruled out the previously suspected Vile.

Even though Zero managed to block Sigma's first attack, he was soon overwhelmed and was used to goad X into attempting to kill Sigma, which would have killed Zero in the process, to see whether X really could hesitate. Upon seeing that X indeed does hesitate, Sigma slashed Zero with his beam saber and left him while he held X captive and launched a missile attack on Abel City. Sometime later, Zero regained his conscious and found X all alone in the facility, heavily damaged. He then brought him back to Hunter HQ.

Mega Man X/Maverick Hunter X

After Sigma's declaration of Reploid Independence on July 4 21XX (June in the US manual of the original game), dubbed "The Day of Σ", Zero, who at that point was the highest-ranked member of the Hunter organization, became the new leader, and he and a repaired X fought together against Sigma's rebellion. Zero saved X during a Maverick attack at the Central Highway from Vile. In Maverick Hunter X, Zero also responded to Vile's question about why Zero would aid a B-Class Hunter like X by informing Vile that he's nothing more than a Maverick at the present. After that, the two split up, with X's task to slow down the Maverick activities in nearby areas while Zero himself was on recon duty at Sigma's fortress.

They eventually rendezvoused at the outskirts and together invaded the fortress. Here, they encountered Vile for a second time. Zero was captured by Vile and imprisoned in a cage (in Maverick Hunter X however, Zero was left unconscious by Vile as bait for X). When X was also defeated by Vile, Zero managed to break free (or regain consciousness, as was the case in Maverick Hunter X) and destroyed Vile's armor by firing a charge shot from point-blank range, which was a successful, yet fatal action. Afterward, Zero handed his Buster Parts to X (only in case X hadn't obtained the Buster Upgrade from the Light Capsule) and encouraged him to continue to fight before ultimately dying in X's arms (Maverick Hunter X also has Zero remarking on the irony of his actions in saving X leading to his death when he earlier told X not to be so careless).

In Vile Mode, unlocked by completing the main game in Maverick Hunter X, Zero's characterization was similar to the main game, including saving X from Vile. However, instead of chasing Vile off, Zero instead retreats with an injured X. X and Zero later reappear as the final bosses at Sigma's Palace Stage 3, where he learns that Vile is, in fact, working against Sigma as well as fighting X and Zero. He ends up severely injured by Vile, although he eventually managed to sneak up and grab Vile's leg and pin him before he could deliver the final blow against X, also referring to Vile's earlier rant about X "changing the world" as "maverick talk," also grounding Vile so he'd be caught in X's charge shot. It is unknown if Zero managed to survive the charge shot that critically wounded Vile, or if, like in the main game, Zero also ended up destroyed in a sacrificial effort to help bring Vile down.

Mega Man X2

After Sigma's defeat, the Hunters tried to salvage whatever remained of Zero from the sunken fortress and found Zero's control chip (which serves as Zero's "brain" and consciousness) which had miraculously survived the destruction of the body. However, the Hunters were incapable of creating a new body for Zero because they were unable to analyze his unique body structure.

Six months later, a group of three Mavericks, calling themselves the "X-Hunters" (Counter Hunters in Japan), contacted the Maverick Hunters and claimed to be in possession of all of the rest of the parts that would be required to rebuild Zero. Although the American translation of the game fails to reveal how the X-Hunters gained the parts, the Japanese version elaborates with the claim that Serges (Sagesse in Japan) added these parts as they were planned additions made by Dr. Wily. The X-Hunters challenged X to a battle in order to win Zero's parts.

X, who didn't want his friend in the hands of Mavericks, accepted and eventually recovered Zero's head, body, and foot parts. Eventually, Zero was reconstructed by Dr. Cain (including the upgrades that Serges had provided) and assisted X in destroying the base of the resurrected Sigma. Trying to fool X however, Sigma had constructed a doppelganger of Zero with Black Armor which he claimed to be Zero; however, this copy is quickly destroyed by the real Zero. This is the canon ending. In the Japanese version of the game, Sigma mentions just before his death that Zero is the last of "Wi...numbers", giving the first hint that Zero is the last of the "Wily numbers", or advanced robots built by Dr. Wily. The American version also gives a vague reference to Zero being the "last of the Doctor's creations."

As a non-canon scenario in the game, if X couldn't retrieve all of Zero's parts, the X-Hunters would steal any parts X had previously collected from the Hunter Base, as well as Zero's control chip. Zero would then be reconstructed as a Maverick and was fought by X prior to his encounter with Sigma. Upon being defeated, a very wounded Zero would awaken from his Maverick stasis and assist X in destroying the Central Computer base. His weakness in this battle is the Speed Burner.

Mega Man Xtreme

Zero played only a minor role in the story of this game. After X managed to escape the digitized version of the Central Highway, Zero would inform him that Mavericks had hacked the Maverick Hunters' Mother Computer, stealing and corrupting data and allowing other Mavericks to run wild everywhere. While X was digitized again and sent back into the Mother Computer to destroy the protection systems that were needed to be taken out to shut the computer down, Zero would handle Maverick attacks in the real world. Also, later during the game, X would be able to find four capsules within the digitized areas, the Zero Scrambles, which allowed him to "summon" Zero to perform an attack or move. However, this was only combat data of Zero and not the real one.

Mega Man X3

The beginning of the Doppler incident finds Zero and X back in their respective commands of the Maverick Hunter Forces. Dr. Doppler's Mavericks lead an attack on the Hunter Base, and X and Zero are forced to return to the base to defend it. Zero joins the Hunters defending the base outside while X ventures into the base. However, when X is captured by the defector, Mac, Zero immediately leaps into the chaos inside the base to save his best friend from the traitor's clutches, being a playable character for the first time. Zero's default weapon is the Zero Buster, however, upon fully charging until he turns green, he will unleash 2 fully charged shots followed by a devastating blow with his other weapon, the Beam Saber.

After completing the Opening Stage, the player can call on Zero anytime by pressing the R-button in the Start Menu, however, Zero adheres to a certain set of rules. He is only able to maneuver through regular parts of the stage and will automatically be replaced by X upon reaching a gate before a boss or sub-boss. The player also cannot die in-game as Zero. If Zero dies, a cutscene will appear where Zero will talk about being damaged and will be unusable for the rest of the game, however, he will still appear in the Doppler Stages to assist X during a sub-boss encounter, taking care of a booby-trap while X destroys the REX-2000.

There is also a secret in-game that will allow X to acquire Zero's saber. If during the completion of the game the player locates Vile MK-II through a teleporter located in either Crush Crawfish's stage, Volt Catfish's stage, or Blizzard Buffalo's stage and defeats him with one (or both) the Spinning Blade and Ray Splasher, Vile will be destroyed, changing the final boss of the second Doppler Stage as well as affecting the level throughout. Upon entering the 2nd Doppler Stage, the player will notice that the Head Gunners are now customized and are twice as difficult to defeat. If the player switches to Zero before entering one of the boss chambers which is normally an empty hallway, a robot called Mosquitus will appear, the only sub-boss that Zero can battle. This enemy is actually very easy to dispatch, however, when defeated, it will crash-land on top of Zero and explode. X will then return and Zero will explain that a few of his power cells have been damaged. He will then hand over his saber to X and then head back to Hunter HQ for repair. Note that this has the same effect in-game as dying with Zero, except that if X leave the game and return, Zero will not reappear within the Doppler Stages as he does when recovering from a standard in-game death. It is also worth noting that if leaving the game and returning with a password, Mosquitus will still appear for X to defeat.

After defeating Doppler's eight Mavericks it begins to see that Sigma is behind the whole Doppler incident. If the player manages to reach the final fight with Sigma and defeat him, he will attempt to possess X. But before he can, Zero appears and hits Sigma with his saber, where he uploaded Doppler's Anti-Sigma Virus-program, believing that it is the only thing that works against him. Sigma seemingly explodes as Doppler's lab self-destructs. If the player loses Zero during the game, Doppler appears instead.

Mega Man Xtreme 2

Zero appears as a playable character with gameplay similar to Mega Man X4. Zero paired up with X to investigate the resurgence of previously retired Mavericks, investigating Laguz Island. He battled Gareth, partner of Berkana, who was reviving the dead Mavericks. Afterward, Zero aided X in the final battle against the resurrected Sigma.

Mega Man X4

Zero's first appearance as a fully controllable character with his own story, which also marked the most tragic point in his life. It also introduced his three-hit Z-Saber combo, as well as his ability to learn special techniques as opposed to X's Special Weapons.

At the beginning of the game, Zero encountered his creator within his dreams, who ordered him to finally obey his orders and fulfill his destiny by destroying his nemesis. When he awakened from the nightmare (which is implied to have happened before), he was immediately dispatched to the Sky Lagoon colony which had been attacked by Mavericks. Repliforce was also confronted at the scene, claiming to assist the Hunters in evacuating the city; however, both factions didn't trust each other, and, as a request for interrogation was declined, the Great Repliforce War broke out.

When the Repliforce was labeled Maverick after the Sky Lagoon incident, both X and Zero were assigned different missions to gather information about Repliforce's coup and to cut off their support lines. Iris assisted Zero on his missions as his operator, like during the Erasure incident from Mega Man Xtreme 2. However, Iris herself was part of Repliforce while her brother, Colonel, was Repliforce's second-in-command and therefore an imminent target for the Maverick Hunters. Iris didn't want the two of them to fight, torn between her care for Zero and her love for her own brother. When the two of them battled in the Ceremony Hall of Repliforce's command center, it was Iris who stopped the two Reploids from terminating each other by begging her own brother to stop since Zero had previously saved her life after the Sky Lagoon had crashed down. Colonel, who had always regarded Zero as a friendly rival, backed off. Zero, on the other hand, stated that someone had to stop Repliforce at all costs, much to Iris' grief.

When Repliforce's coup began, Zero rushed to the space port to stop the ascension of the military troops to the newly constructed space station of Repliforce, Final Weapon. There he battled Colonel, this time not holding anything back, just like his former friend, with Zero being the victor of the fight. After that, he traveled to the Final Weapon where he was, much to his surprise and horror, encountered by Iris, who was blinded by her grief of the loss of her brother and anger for Zero killing him. She had salvaged Colonel's Control Chip from his remains, fusing it with her own programming, thus resulting her body to transform into a massive Ride Armor-like combat form which Zero was forced to battle. Even though he didn't mean to, Zero damaged the exterior power core of the structure, resulting in the destruction of the armor. He hurried to Iris' body, however, it was too late to save her. Whispering to Zero that she did all this because she wanted to live in a world for Reploids only, and that he could live in that world too. She died in his arms and Zero, who was totally overthrown by the pain, began questioning his own reasons for fighting and the means of his own existence. Filled with anger, he confronted General, leader of Repliforce, defeating him in battle. Upon the end of the fight, General realized that someone had taken control of Final Weapon, aiming it at Earth. Zero rushed to the Final Weapon control center, only to find Sigma waiting for him. Sigma reveals part of Zero's past at a time when Sigma was still the leader of the Maverick Hunters.

During this vision, Sigma and the Maverick Hunters are called to an abandoned laboratory to fight a Maverick of immense power. Sigma enters the building and the Maverick is revealed to be a maniacal Zero, with no power other than sheer brute strength and rage. Zero manages to overpower and grievously injure Sigma, but before he can deal a finishing blow, the light in the center of his forehead flashes on, revealing a "W" and causing Zero to collapse in pain. Sigma gathers his remaining strength and punches Zero in that light, rendering him unconscious. Sigma leaves, asking the Reploids outside to have the Maverick delivered to Dr. Cain for analysis. It is believed that during this fight that both Zero and Sigma were infected with the Maverick Virus, which later caused Sigma to betray the Maverick Hunters, however it corrected the flaw in Zero's programming, allowing him to awaken and later join the Maverick Hunters.

Zero Iris

After the death of Iris, Zero is lost in pain.

After Zero had destroyed Sigma and the General had sacrificed his life to make the Final Weapon self-destruct, Zero escaped the destruction in a small spacecraft, thinking about what he had done. He hadn't been able to save anyone he cared about. He had killed his own friend Colonel, the General, and Repliforce with him, who in the end has only been manipulated by Sigma and the Mavericks. Most of all, he lost Iris, who he had cared about for so long. Questioning whether or not Reploids were destined to become Mavericks after all, he returned to Earth.

If the game was played by X, Zero would only appear at the very end of the story, contacting X from Hunter Base upon his return to Earth by spacecraft. X, wondering what would happen if he turned Maverick, asked Zero to take care of him if that would ever happen. Confused, Zero didn't respond to X's request, although he seemingly realized X's seriousness about the topic and the eventual battle between him and his best friend.

Mega Man X5Edit

The space colony "Eurasia" was set to impact Earth, recently being coated in a large outbreak of the Maverick virus, which would cause catastrophes of unimaginable proportions. In the meantime, X and Zero faced Sigma on Earth and easily defeated him; however, Sigma lost on purpose to spread the Sigma Virus around the world. Due to this, thousands of Maverick Hunters turned Maverick, yet, the fall of the colony posed to be the bigger threat. In order to stop Eurasia's impact, X and Zero both would gather several enhancement parts to power up an old energy cannon, known as "Enigma", to destroy the colony before it could devastate the planet. While doing so, Zero noticed his strange reaction towards the Sigma Virus. While others (including X) got hurt by being surrounded by the virus, he himself actually felt energy growing inside himself; multiple infections of Sigma Virus anomalies even turned him invincible for a brief period of time. Behind the scenes, Lifesaver informed Hunter General Signas about his concerns regarding Zero, but also that there might have been a chance to develop antibodies from his DNA to cure the Maverick/Sigma Virus. Yet, the accomplishment of the Enigma was rendered priority one.

However, it didn't matter how much the cannon was powered up, complete destruction of the Eurasia was impossible and only delayed the impact (in the game it's possible to destroy Eurasia with only the cannon, but story-wise it didn't work). As a last resort action, a Space Shuttle was readied to be launched and directed right into the colony to have it self-destruct right at the core. The shuttle would be operated by Zero, who volunteered because he felt that the world needed X more than himself. The operation succeeded, and Zero survived; however, debris would still rain down on Earth. Zero was later rescued by the Hunters, but the peace only lasted for a short time as a new threat arose from the debris of the Eurasia.

A new virus, merged from the virus inside the colony and the Sigma Virus, called the "Zero Virus" by Alia, had begun to effect the impact area. The area flooded by the new virus was strangely deformed and was filled with anomalies that even resembled Zero. Also, strange Mavericks were found in the area, bosses that actually resembled earlier bosses such as the Shadow Devil and Rangda Bangda. The closer X and Zero got to the source of the virus, the higher Zero's viral infection level rose, yet he still didn't show any Maverick behavior. Not wanting Zero to become a Maverick, X would fight his friend in order to have him brought back to Hunter Base. Eventually, the battle would end in a draw (with X using Soul Body on Zero and getting injured by him while using it). Upon seeing X and Zero both completely exhausted after their battle, Sigma would reveal himself to destroy them. However, Zero managed to prevent this, protecting X and himself and forcing Sigma to retreat.

If the one who would pursue Sigma was Zero, Sigma would reveal to him that he let the colony fall on Earth solely to purify Zero's body with the virus to clear his mind and awaken his true self. Upon defeating his first form, Sigma would also reveal to Zero that he met an "Old Man" which knew a lot about Zero and his past, caring for him like a father and that it was that man's suggestion to flood Zero's body with the Virus to awaken him. After defeating his large battle body form, Sigma would then try to take X, who was still left unconscious at the scene of his battle with Zero, down with him. Zero would take most of the hit, seriously damaging him. The remains of Sigma attacked Zero and X one final time, impaling both of them through the chest area, but was then completely destroyed by Zero, who gained consciousness briefly and fired a charge shot at him from his buster.

Exhausted and damaged from the battle, Zero finally realized that he was going to die, and while in a state between life and death, he began recalling memories of his creator and his true purpose of existence. Yet, his memory circuits began to cease to function. After recalling his memories of Iris and apologizing to her, Zero asked X to live for him, bringing peace to the world. After X was saved and repaired by the spirit of Dr. Light, X searched for Zero, finding nothing but his Z-Saber, which he kept in order to honor his fallen friend.

Awakened Zero

Awakened Zero.

As a non-canon scenario, if the Shuttle Operation was unsuccessful, the large amounts of the Colony Virus, together with the Sigma Virus Zero had already been infected with from Earth, would "awaken" Zero upon crashing on Earth, thus challenging X to a battle. His mind now cleared and caring about nothing but his mission to fight X, Maverick Zero battled X, resulting in a draw. After taking massive damage during the fight, Sigma revealed himself and prepared to destroy X. Zero, however, regained consciousness and he jumped into the line of fire, protecting X with his body, only to get mortally wounded in the process. When X destroyed Sigma in this scenario and was damaged badly, Dr. Light would appear to save him; however, Light erased X's memories of Zero and would implant a protection inside X's mind so no information about Zero would be accepted.

Originally, X5 was supposed to be the final game of the series and Zero getting killed would make way for the Zero series. However, X6 was produced unbeknownst to Inafune and without his approval, and since the plot of X6 involved Zero once again, he had to modify his Mega Man Zero concept in order to not make the story more confusing.

Mega Man X6Edit

Set a few weeks after the Eurasia incident, Reploid scientist Gate found a piece of Zero's body near the crash site. Using the information he gathered about the Sigma Virus and Zero's DNA,[7] Gate has seemingly gone mad, creating the new Nightmare Virus, a discolored clone of Zero (called "Zero Nightmare"), and the near-invulnerable Reploid, High Max. X, taking the assault on Zero's reputation personally, set out to investigate. Upon destroying the Zero Nightmare, X is reunited with his friend, mysteriously repaired and carrying a brand new Z-Saber. Together, X and Zero set out to defeat Gate and the imperfectly resurrected Sigma.

X6 scene 14

Zero reunites with X

Who exactly repaired Zero was never directly stated.[8] In the Weapon Center, the Dr. Light capsule hologram denied knowing who repaired him.[9] It should be noted that the reunion between X and Zero had Zero stating that he hid himself away while he "healed".[10] In the English translation, Zero told X that he repaired himself.[11]

Zero's ending in this game helps to mend the storyline between the X and Zero games. It shows Zero being sealed to remove a component from his body (presumably something having to do with the virus' influence on him, and/or his original murderous persona). This was originally going to show that the X series had ended, but fans loved the series so much, Inafune was forced to continue, making many people believe that this is either a glimpse of the future, or non-canon. However, recently revealed backstory information in the Japanese Mega Man Zero artbook has revealed that this ending is indeed canon, takes place in an unspecified time period beyond the last X series game, and is in fact considered the first of two different times when Zero sealed himself away (the second time being after the Elf Wars, when he sealed himself away once more in the Rockman Zero TELOS drama tracks, and was then finally reawakened in the Zero series).

X6 scene 51

Zero about to be sealed

Alternatively, it is possible to clear Mega Man X6 without ever finding Zero. In this event, cutscenes show that Zero is indeed alive, but X and the other Maverick Hunters never find him. Zero leaves on his own, stating that there's something he needs to take care of. Like the alternate ending to X5, canonically, this ending does not happen.

Mega Man X7Edit

Zero is responsible for the bulk of the Maverick Hunter workload due to the fact that X has recently refused to battle for any reason, due to his doubts about the Hunters' violent methods (Zero seems to have some resentment towards the workload, as indicated when he says, "I can't believe I'm back here again!" in an irritated tone in his introduction, which could also imply that he's back in the same setting as the Opening Stage of Mega Man X). Zero captures a mysterious Reploid, Axl, who has just recently abandoned the vigilante group Red Alert. Axl assists Zero in stopping Red Alert's rampages, and eventually X rejoins them. While fighting alongside Axl, Zero learns from him at least some of the details about Red Alert's downfall. After the battles, Zero has nightmares of X attacking him, out of obsession for eliminating Mavericks (possibly foreshadowing the rise of Copy X in the Zero series).

X7 scene04

Zero taking Axl to see X

X7 signified a few changes to Zero's gameplay. His Z-Buster was eliminated altogether, and in addition to learning new attacks from defeated Mavericks, Zero can also gain other melee weapons to replace his saber. This tradition would continue through the rest of the Mega Man X series and up to the Mega Man Zero series.

Mega Man X8Edit

Zero continues to work with X and Axl, now an official Maverick Hunter, in dealing with new threats. One of the new navigators, a purple-haired girl named Layer, has shown a romantic interest in him; Zero has not returned her feelings however, simply keeping the relationship professional. Zero's memories of the virus incident from X5 continue to haunt him, fueling his hatred towards Sigma. Upon confronting him, Sigma confirms that Zero is the original carrier of the Maverick Virus, which was transferred to Sigma prior to the first X game (presumably it happened when Sigma shattered Zero's head gem as depicted in X4, though the unlockable animation The Day of Σ in the PSP remake has put a few doubts on this). This information was long-since stated in Japanese sourcebooks, as well as implied as early as X4, but was never before made officially available to the public in other regions.

Mega Man X: Command MissionEdit

In the game, Zero is sent along with X and another Reploid, Shadow, to investigate Reploid uprisings in Giga City. Zero is separated from X after Shadow betrays them and was presumed dead, until he reappears some time later and attacks one of the rebelling Reploids in a mechaniloid factory. At this point, Zero joins X, Axl, and a number of other Reploids that X assembled to assist him. With Shadow's betrayal still fresh in his memory, Zero is unwilling to trust X's new friends, and promptly decides to work alone. However, one of the Reploids, Spider, risks his life in Zero's defense. After this, Zero decides to rejoin X's group permanently, although Spider eventually turns on them as well and reveals himself as Colonel Redips. He had hid his true identity from the group by using a replica of Axl's DNA change, hinting toward the possibility that Spider could have actually existed at one point (since Axl needs to take DNA from a Reploid in order to change into it). Zero briefly hesitated when his allies attempted to stop Redips from using the Supra Force metal, presumably out of shock that Spider and Redips were the same and thus he was "badly duped." However, he would recover and, with the others, defeat Great Redips in the end, before returning to Earth in a broken off part of the elevator.

The Elf WarsEdit

At some unknown point, Zero realized that he carried the virus inside him and may even be continuing to spread it all over the world during his missions as a Hunter. Thinking that the world wouldn't be safe as long as he was still active, Zero admitted himself into a research institute in order to get rid of the virus within him. At the same time, a project was started to analyze Zero as it had been revealed previously (during the Eurasia crisis to be exact), that Zero actually reacted positively to the Sigma Virus, and therefore might hold anti-bodies for the infection. Zero was sealed away and brought to a government lab. At some point, Zero's mind was extracted from the body, possibly for security measures in case something would go wrong while researching it.

For an unknown amount of time, Zero's body was studied by government researchers. One of them, an unnamed female ancestor of Ciel, managed to create the "Sigma Antibody Program", a Cyber-elf capable of reverting the devastated programming of infected Mavericks and therefore destroying the virus completely. This Cyber Elf was the Mother Elf.

However, weapon researcher and DNA revival specialist Dr. Weil, who also worked in the lab, planned a different way of dealing with the Mavericks, as he was unsatisfied with the result. Weil started a conflict that would ultimately cost the lives of 90% of all Reploids and 60% of all humans. This four-year-long period of war was later dubbed the "Elf Wars".

Thinking that it wasn't enough to simply cure the Reploids from the virus while they still posed a threat to society due to their free will, Weil decided to create his own, radical solution, while making himself ruler of the world in the process. Project Elpis was the end result: to create a Reploid who would become the perfect ruler, by using the power of the Mother Elf to control all the Reploids in the world, thus preventing them becoming Mavericks in the first place.

However, since the world was at peace at the moment thanks to the Mother Elf, he needed to give the government a reason to sanction Project Elpis. He secretly stole the Mother Elf and reprogrammed her into the Dark Elf, whose purpose was to create Maverick outbreaks by brainwashing Reploids. Baby Elves, small copies of the Dark Elf, were mass-produced to cause violent Maverick outbreaks worldwide.

As new Mavericks arose and caused terror and destruction in scales never seen before, the government heeded Dr. Weil's pleas and sanctioned Project Elpis to bring this new and devastating conflict to an end. For the project he was given Zero's body, which possessed the necessary virus countermeasures for creating the perfect ruler, Omega, the messiah of Dr. Weil.

For Omega to control all Reploids worldwide with the Mother Elf, a massive armor was constructed around Omega for the Mother Elf to fuse with it. In addition the armor also boosted Zero's body to its absolute limits and granted it the ability to regenerate any damage. Along with the armor, Omega received new weapons, suitable for his new size and weight. Unknown to everyone Omega received a new personality, which was absolutely loyal to Dr. Weil's orders. With Omega completed by fusing it with the Dark Elf, the baby elves would be redundant as they were no longer needed.

In the fourth (and what would be the last) year of the war, Zero, in possession of a new body Ciel's ancestor created for him, would wake up so he could fight alongside X against the new threat. At some point during the conflict, which were now known as the Elf Wars, Zero reclaimed the Dark Elf from the mavericks and used her to bring the uprisings to a end.

Elf Wars

Omega during the closing period of the Elf Wars

It was then where Weil revealed his true colors and ordered Omega and a group of Mechaniloids, similar to Neo Arcadia's later Golem models, to attack his former allies. However, because Zero reclaimed the Dark Elf in time, Omega was unable to fuse with the Dark Elf. He was defeated after a hard battle by X and Zero using the Final Strike.

After the war had ended, Zero decided to seal himself away again, this time, forever. Though X tried desperately to stop his friend, the sealing process had already begun when X arrived, and could not be stopped. Before he lost consciousness, Zero told X that, as long as he was still around, the bloody history would repeat itself over and over again. Before the seal was complete, he encouraged X that this was the right way and that he wanted to believe in human kind, just as X believed in them. With these final words, Zero's seal was complete.

Neo Arcadia eraEdit

MMZ Zero

Zero in the Mega Man Zero series.

Mega Man ZeroEdit

At the beginning of the game, Zero was discovered in suspended animation in an abandoned laboratory by a human scientist named Ciel, who leads a band of Reploid Resistance. Ciel used the Cyber-elf Passy to revive Zero, who in turn saved Ciel from the forces of Neo Arcadia that was pursuing her and her comrades. Zero, however, was suffering memory loss due to "hibernation sickness". As it turned out, Neo Arcadia was the government of the world at this time period. Reploids were discriminated against and often deemed Maverick and terminated without justifiable cause. Copy X, a ruthless, conceited weaker clone of the real X, was in charge of this policy. Zero agreed to join Ciel's cause in fighting this oppression of Reploids. Zero would then go on to defeat Copy X's 4 Guardians as well as destroying Copy X himself.

After the battle with Copy X, Zero was declared missing by the Resistance, after the Neo Arcadian Core was destroyed. In truth, Zero survived the explosion, and is traveling in the desert, continuing to fight Neo Arcadia that set its sights on him.

Mega Man Zero 2Edit

One year later, Zero is still traversing the harsh desert, and still hunted by Neo Arcadia. After another battle with the Neo Arcadian Forces, Zero finally succumbs to his injuries and collapses. When he wakes up, he is now in the new Resistance Base, brought there by unknown means (later revealed to be Harpuia's doing), and meets the new members, including a new commander, Elpizo.

Z2 scene 03

Ciel showed Zero her research on energy, the former thinking that it will give Neo Arcadia a reason not to fight them anymore. Zero tried to hold off Elpizo's Operation Righteous Strike long enough for Ciel to finish her research, but in the end Elpizo still continued his plans, and Zero had to rescue him. Although Elpizo survived, he was driven to madness by the defeat, and Zero had to spend the larger half of the game trying to find him.

During the game, Zero also learned of what had happened before his sealing; Sigma and his Mavericks were defeated, but some time after the Elf Wars broke out, Zero himself helped X to end them by defeating and banishing Omega, the most terrifying "Reploid" of the time. Several decades after Zero was sealed, X sacrificed his body to stop the worst Cyber-elf of all, the Dark Elf, leaving him in a more ethereal form. X's body is destroyed and the Dark Elf is released by the now-rogue Elpizo. Zero defeats Elpizo, but the Dark Elf escapes. She and Zero appear to know each other, and X informs Zero that the Dark Elf was not always known by her current name. Her powers became a threat due to a curse by Dr. Weil, the man who started the Elf Wars, at which point people began calling her the Dark Elf.

Mega Man Zero 3Edit

During the two-month gap between the third second games, there has apparently been a truce between Neo Arcadia and the Resistance. Ciel, having finished her energy research by creating the "CIEL system", submitted her work to Neo Arcadia, hoping to open up the chance for peace talks. In the meantime, Zero and Ciel lead a small group through a snowy mountain, as while they were trying to locate the Dark Elf (presumably to end her curse), they found another energy signature resembling the Dark Elf located there. Upon arrival at the origin of the signal, they discover an immense ship. The Neo Arcadians had roped off the ship, so Zero decides to get a closer look by sneaking in. However, upon arrival, Ciel and the rest of the group was discovered by the Neo Arcadians. they didn't seem to be killed though, thus confusing Zero. Harpuia then appears and says that he's letting them off the hook, as there's "bigger fish to fry". After Harpuia leaves, and Zero tries to figure out who the Dark Elf is and why she seemed familiar, Zero then hears a monstrous voice calling him. Upon arriving at the interior of the ship, Zero discovers that Fefnir and Leviathan, as well as their entire unit, was soundly defeated by an immense figure: Omega, the Devil Reploid. Zero then realizes that Omega was the one who called him, and they fight. Zero seems to defeat Omega and cause grievous damage, but then Omega started regenerating the wound. Harpuia then cuts in and is about to deliver the coup de grace when a mysterious man, Dr. Weil, tells Omega that he is to serve Harpuia as an ally. Copy X MK II then appears and announces that he revoked Dr. Weil's exile. Weil, Copy X, Harpuia, and Omega then depart after some discussion, although not before Weil cryptically remarks that he's interested in how well Zero will do "in that body of his."

After a few missions, Zero and the Resistance then learn that Neo Arcadia is planning to launch a missile containing Omega into Area Z-3079, a human residential area to capture the Dark Elf. Zero infiltrates the Missile Facility and divert the missile, however, he wasn't able to stop the launch. Not wanting to just let Neo Arcadia destroy a human population just to acquire the Dark Elf, he boards the missile to destroy Omega before it arrives at its destination. Unfortunately, Dr. Weil had anticipated Zero's actions, so he had placed Crea and Prea on guard duty of Omega's chamber long before the launch. While he may have defeated them, they still bought the Omega Missile enough time to reach its target. Zero barely escapes the impact of the missile, and wakes up to see Omega absorbing the Dark Elf, and transforming. Harpuia, having been retired from his position of Neo Arcadia's military force, then attacks Omega in a last ditch effort to stop Weil and Omega, and protect humanity, even if it meant going against X. Unfortunately, thanks to Omega's absorbing the Dark Elf, Harpuia's attacks are ineffective. Zero manages to save Harpuia and himself at the last second by telling the Resistance to transport them back.

Neo Arcadia then contacts the Resistance base, with Copy X saying they'll call a truce under the condition that they hand over the Ciel system. However, Ciel and the Resistance declines, as she doesn't trust them due to them destroying a human settlement just to get the Dark Elf. Their refusal results in an invasion with three units coming from the desert, the forest, and the Antarctic to attack the Resistance Base. Zero manages to take down the invasion, destroying the newly resurrected Hanumachine, Anubis Necromancess, and Blizzack Staggroff. Afterwards, Zero infiltrates the main base of Neo Arcadia to stop the invasion once and for all. Zero fights against Copy X Mark II after a debate about how things should be done. After the battle, the original X approaches Copy X and reveals that Omega and Dr. Weil had used him to gain more power, and abandoned him. Copy X then attempts to transform into his second form, despite X's warnings about a device implanted into him, and is destroyed as a result. Dr. Weil then announces X's death to Neo Arcadia, claiming it to be the work of the Resistance, and evokes Ordinance 8 in order to become its new ruler. Zero and X then decide to go their separate ways, although not before X cryptically informed Zero that it "was the heart that matters, not the body."

After a few more missions and collecting data, Zero learns from Ciel that Dr. Weil is planning on re-enacting the Elf Wars. Unfortunately, Dr. Weil and Omega then takes control of all the Reploids on the planet once more. X, however, uses his powers to protect the Reploids in the Resistance Base from Weil's control. Zero sets off to stop Weil, tracking him down to his secret laboratory, which incidentally, was close to where Zero was found at the beginning of the series.

Zero is confronted by Omega, and the two do battle. After defeating two of Omega's forms, Zero lands with Omega's remains in the very room which he was sealed in. Weil then reveals that Zero is a fake, and that Omega is in fact the "real" Zero, and Zero's original body breaks out of the shell that was Omega's previous form. Zero, however, still defeats Omega Zero after an intense duel. When Weil attempts to heal Omega of his wounds with the Dark Elf, the remaining 3 Guardians appear and attack Omega. X himself appears alongside the Guardians, and told Zero of Weil's deception: that Omega may be using Zero's original body, but the "fake" Zero still has his real soul.

So, regardless of Omega using his original body, Zero destroys him (presumably) once and for all, but Weil escapes. The Dark Elf, now free of her curse and called Mother Elf once more, roams free. However, X cannot roam in the real world any longer. Before X goes away, he tells an unconscious Zero to always protect the peace between Reploids and humans, a promise Zero keeps up to the heart in the next game.

Mega Man Zero 4

Eight months after the destruction of Omega, Neo Arcadia remained under Weil's control. After Weil began to terminate humans who opposed him, several groups of humans escaped the city that used to be their utopia. When the Resistance received the knowledge of this, they immediately dispatched a team to assist and protect the refugees. Zero, along with Ciel and a few other Resistance members, intercepted an assault team of Weil's Variant drones (remodeled Mechaniloid soldiers which had replaced the Pantheons) that attacked a refugee truck Caravan. After countering the attack, Zero and Ciel met Neige, a human journalist who tried everything possible to both bring all people safely to their new refuge, Area Zero and to find out the whole truth about Weil.

The Variant attack, however, was just the beginning. Zero, while investigating Area Zero, encounters Craft and the Einherjar Eight Warriors, who all serve directly under Dr. Weil. Craft tells Zero of Operation Ragnarok, a plan to destroy all inhabitable areas outside Neo Arcadia so no one can escape Dr. Weil's rule. Zero defeats 4 of the Einherjar one by one and then repels an attack on Area Zero by Craft himself. The latter's objective was to kidnap Neige, who was an old friend of his. Zero rescues Neige from the prison Craft took her to, but not before Neige managed to push a little of her ideals back into her old friend.

When the rest of the Einherjar Warriors are eliminated, Craft revolts against Weil and commandeers the "Ragnarok" space station, threatening to obliterate Neo Arcadia with the station's laser cannon. The Resistance immediately commences the evacuation of the city while Zero storms the space station. Despite his efforts, Zero is too late and Craft opens fire, destroying the city. Zero then engages Craft in combat and defeats him. Mortally wounded, Craft asks Zero why he continues to fight for the humans that feared him and all Reploids. Zero replies that he was obligated by a promise he has made to a friend and their faith in the human race. Realizing what he's done, Craft asks Zero to continue living up to that promise, before shutting down for good.

All is not well, however. A second laser fired from Ragnarok alerted everyone that it was still operational and that the station is now falling down to Earth. After going through Ragnarok's defenses to reach the core, Zero discovers Weil waiting for him. Having actually survived Ragnarok's laser fire, Weil teleported into the space station after the blast, maneuvering it to crash into Area Zero. After the first of their two battles, the space station is damaged. Ciel pleads for Zero to return to Earth, lest he gets stranded due to increasing transporter interference. Seeing Weil still alive, Zero passes the offer to go back and proceeds to finish him off in their second battle, ultimately sacrificing himself as the destruction of Weil's last form causes the station to explode.

Zero's sacrifice opens the eyes of many, finally bringing peace between the Reploids and humans left on Earth. The aftermath, however, leaves his friends grieving at his apparent death (his actual fate remains uncertain), especially Ciel, who is later inspired to pick up his work to create harmony between Reploids and humans.

Mega Man ZX

Zero returns as Biometal Model Z, which contains the "soul" of Zero. Although Biometal Model Z is not usable by itself, it can be combined with Biometal Model X to form Model ZX, the title character.

After defeating Prometheus, Zero appears in a flashback scene in Vent's story, where Prairie explains that her sister was a human (obviously referring to Ciel) that defended the Reploids. The scene then shifts to a view of Zero and Ciel looking at an army of Pantheons. Zero is mentioned when (again in Vent's storyline) Prairie explains that Model W is the spirit of Dr. Weil and that the last time Dr. Weil had appeared, he was stopped by Zero (although the game never addresses Zero by name, simply calling him "a hero").

Omega also appears as an optional boss in Area N-1. Defeating him in Normal or Hard will grant access to a mysterious artifact that allows the player to use Model OX.

Mega Man ZX Advent

Model Z, alongside Model X, reappears in this game and are still in Vent/Aile's possession. After Ouroborous starts falling apart, Model Z decides to take down the enemy Mega Men by himself and allows Aile/Vent to go rescue Grey/Ashe, who fainted after the battle against Master Albert. Model Z manages to freeze the four Biometals, which freezes the users themselves. The conclusion of the battle is unknown since Aile/Vent did not mention anything about Model Z during the ending. However, if the player beats hard mode, then a secret ending shows the four enemy Mega Men alive and well, in their MegaMerged form. As of then, Model Z's whereabouts are unknown, mirroring Mega Man Zero 4. He is implied alive, as he said before he disappeared "It's not the day to meet my maker," referencing that no matter what, even in death, he continues to live, resurrected in some way or another, always fighting with whoever he is with.

An interesting point in this is the fact that he seemed to die aboard Ouroborous, made from Model Ws, which are made from pieces of the Ragnarok, the space station where Zero appeared to die in Mega Man Zero 4.
