Mega Man Zero (series)

The Mega Man Zero series made its debut in 2002 on the Game Boy Advance and takes place one-hundred years after Zero had sealed himself after the Elf Wars. In this time-period, both the "Maverick Wars" and "Elf Wars" have ended, but a new threat has arisen. A young scientist named Ciel, leader of a "Resistance", is searching for the legendary Reploid Zero to help in the fight against the oppressive forces of Neo Arcadia. She comes across the ruins of the lab in which Zero was sealed and awakens him. Thus, Zero joins the Resistance and takes up his sword once again to fight against evil.

Timeline
The following is a time-line of events that precede, include, and directly follow the Mega Man Zero series.

Between the X and Zero series

 * 21XX: The Maverick Wars continue during the Mega Man X series.
 * Mega Man X6: Sigma is killed by X. An indefinite time later, and without the knowledge of X, Zero allows himself to be sealed in his ending of the game to be analyzed by scientists. The period of his sleep is planned to end 102 years later.


 * Cyber-elf technology is invented by analyzing Zero. Cyber-elves are pure energy with artificial intelligence. They were invented for the sole purpose of ending the Maverick Wars. Their creators designed them to amplify the power of Reploids and to combat the effect of the Maverick Virus. The key in this development was the creation of the Mother Elf, which Mega Man X used in order to permanently destroy the effects of the Maverick Virus and thus end the Maverick Wars.


 * Neo Arcadia is built as a major city-state sometime after the Maverick Wars as a place where humans and Reploids can live in peace.


 * The Mother Elf is stolen by Dr. Weil, who turns it into the Dark Elf and instigates the Elf Wars. This four-year period is so violent that it destroys 90% of the planet's Reploids and kills 60% of the planet's humans, and leaving much of the world barren. During this time Zero's original body is stolen by Weil to construct Omega. Weil also creates copies of the Dark Elf, the Baby Elves, to control all Reploids in the world. Zero is given a new body using his original mind. Zero and X fight against Weil's forces and, in the end, go up against the powerful Omega, defeating him with the Final Strike attack. Dr. Weil is banished from Neo Arcaida, being punished by receiving a regenerative armor so that he will survive and "suffer" forever in the inhabitable lands outside Neo Arcadia. Omega is banished to space. After the battle, Zero seals himself again.


 * After the Elf Wars, X seals the Dark Elf after the Elf Wars at Yggdrasil using his own body.


 * The Four Guardians, Sage Harpuia, Fighting Fefnir, Fairy Leviathan, and Hidden Phantom are created.


 * Copy X is built by Ciel.


 * Copy X labels several innocent Reploids as Mavericks in Neo Arcadia, and a Resistance is formed to confront him.


 * The Reploid TK-31 accidently saw confidential informations, and a week later is considered Maverick by the Eight Gentle Judges. He escapes from Neo Arcadia with HE-22, a member of the Resistance. TK-31 goes to Area 7 and takes one Baby Elf with him, and changes his name to Elpizo based on the informations he saw. This event happened sometime between the Resistance's formation and Mega Man Zero 2.

Mega Man Zero
Ciel and her companions go after the legendary Reploid Zero to help them in their fight against Neo Arcadia, and are followed by Neo Arcadian forces. They come across the ruins of an ancient laboratory where Zero is sealed up, having been in stasis for a century. The world that Zero is brought into is one drastically different to the one from a century earlier- Reploids are living under constant oppression at the hands of a maniacal ruler who can call them "Maverick" at a whim, and the ruler is none other them his former partner, Mega Man X. Zero fights X's forces, led by the Four Guardians - Fefnir, Harpuia, Leviathan, and Phantom, and then learns the truth from Ciel: The current ruler is not the original X, but rather is a "copy." Copy X was created when the real X went missing some time ago. Zero goes to confront and defeat Copy X and, upon doing so, is almost destroyed by the large explosion that results. Then, the original X appears in the form of a Cyber-elf and tells Zero that he must continue the fight and protect the peace as he rests for a while. The Resistance moves to a new base, as the current base was no longer safe.

Mega Man Zero 2
One year has passed since Zero defeated Copy X and ever since then he has been wandering around in the desert in disrepair, fighting off wave after wave of Pantheons. In Neo Arcadia, the remaining three Guardians (Phantom having sacrificed himself trying to hinder Zero's assault on Area X) have assumed control in the place of Copy X, unbeknownst to the humans who had revered Copy X (whom they thought to be the "real X") as a savior. Ciel tries to solve the Energy Crisis that seems to have started much of the problems, leaving command of the Resistance to a Reploid named Elpizo. However, Elpizo believes her efforts to be futile and makes an assault on Neo Arcadia from which he is the only returning survivor.

After that, Elpizo returns and believes that the only thing that will stop the madness is the Dark Elf, the very thing that started the Elf Wars in the first place. Using some of its unsealed power, Elpizo breaks into the temple at Yggdrasil, destroys the body of the original X, unsealing the Dark Elf. However, Zero comes to the rescue, stopping Elpizo from unleashing the Dark Elf's power on the world and defeats him once and for all. Elpizo apologizes for everything that he's done and the Dark Elf turns him into a Cyber-elf (saving him). Elpizo then tells Zero that the Dark Elf isn't evil and then he leaves. X appears (in his Cyber-elf form) and tells Zero about the true nature of the Dark Elf, who was created to be a savior for Reploids and humans during the Maverick Wars but was manipulated by a man named Dr. Weil. After this the Dark Elf leaves and a voice calls for Omega to come into action.

Mega Man Zero 3
During the two months after Elpizo's defeat, an unofficial truce was made between the Resistance and Neo Arcadia. Ciel has solved the energy crisis, developing what she called the Ciel System, and entered in contact with Neo Arcadia to send it to them. Meanwhile, a spaceship crashes and emits energy similar to that of the Dark Elf which prompts Zero to go and investigate. At the spaceship, Zero encountered a huge Reploid named Omega that not even Fefnir and Leviathan can take down. While Zero halts his investigation to deal with Omega, a new Copy X assumes command of Neo Arcadia and Dr. Weil introduces himself (he seems to be back from his exile), Copy X admitting him in as his advisor. Copy X and Weil challenge Zero and the Resistance as to which group will capture the Dark Elf first, thus ending the truce.

Weil and Copy X then launch a missile at a densely-populated area that humans live in so Omega can capture the Dark Elf. Zero then had to counter a severe offensive against the resistance after Ciel refused to give her Ciel System to Neo Arcadia. Zero goes to battle and defeat Copy X once more, but Dr. Weil betrays Copy X and detonates a bomb held within his body that goes off when he tries to access his second form. Weil assumes control of Neo Arcadia and uses Omega and the Dark Elf to seize control of the Reploids.

Zero manages to defeat Omega's Dark Elf-enhanced form, defeating him twice, but out of Omega's remains emerges a Reploid that looks exactly like Zero. Weil then informs Zero that he is merely a copy and that Omega occupies his true, original form, which Zero barely defeats. Then, before Omega is rejoined with the Dark Elf, the Guardians come and do further damage to him. X reappears and tells Zero that what Weil says is true: they battled Omega in the past and sealed him long ago. Zero decides that he must finish Omega off, regardless of whether or not he occupies his original body. Omega explodes, knocking Zero "unconscious," and he sees visions of X. X tells him that he is out of energy and can no longer remain in the human world. X is confident that Zero will carry on the battle to protect peace and fades away. X is then believed to have "retired into cyberspace." The Guardians also die in the explosion. The Dark Elf brings Zero's unconscious body back to the Resistance HQ and, with Weil's curse broken, the Dark Elf becomes the Mother Elf once again and flies away.

Mega Man Zero 4
Not long after Zero's battle with Omega, humans begin to leave Neo Arcadia, which is under the dictatorship of Dr. Weil. Humans who oppose Weil's rule are labeled as Mavericks and quickly dealt with, so a caravan departs under the guidance of a journalist named Neige. The caravan is attacked by Variants and Ciel and the Resistance come across them along with Zero. The caravan explains that they are heading to Area Zero, the last known inhabitable area outside of Neo Arcadia (Area Zero is the remains of the Eurasia space colony that fell to Earth in Mega Man X5). Soon after this, Zero learns of a plot from Craft, Weil's second-in-command, to destroy Area Zero. Known as Operation Ragnarok, Weil was going to destroy all inhabitable areas, especially Area Zero, and force humans to come back and live under his rule. Thus, Zero sets out to defeat his Maverick leaders.

In reality, the Maverick attacks were only a distraction to occupy Zero so Weil can finish his most powerful weapon, the space station Ragnarok, which can easily destroy Area Zero with its laser. Yet, Craft rebels against Weil (he is in love with Neige) and instead fires the cannon upon Neo Arcadia. Zero puts an end to Craft and the Resistance is dispatched to rescue the survivors. Weil then teleports directly into the satellite to manually crash it into Area Zero, but Zero teleports back in and makes his way to Weil.

Weil reveals to Zero that he is indeed human, although Zero doesn't understand how he could have lived for well over a century. Weil reveals that over a century ago the humans who exiled him gave him a regenerative suit so that he would live through his exile and not die or get sick. Therefore, he tells Zero that he will not be able to destroy him. Moreover, should he ever manage to kill or even just harm him he will be considered a "Maverick." In the end, Zero decides that he doesn't care about justice or being called a Maverick, he only cares about protecting the ones he cares for. Weil fuses with the Ragnarok core, then with the entire Ragnarok itself, to battle Zero. However, Zero destroys Weil and Ragnarok, destroying the satellite before it reaches the atmosphere.

On Earth, Ciel, the Resistance, and the survivors see the explosion and realize that Zero did not escape. Ciel promises to make the world a peaceful place for humans and Reploids but deep inside she believes that Zero is still alive somewhere. The last scene is somewhere in the desert, where a crater shows the charred remains of Ragnarok and Zero's broken helmet.

Trivia

 * Mega Man X5 was originally planned to be the last game of the the X series, continuing in the Mega Man Zero series. The story had to be changed by Capcom as Mega Man X6 (2001) was released before the first Mega Man Zero (2002).
 * In Megaman Battle Chip Challenge, there´s a carpet in Dex´s house wich has the main logo of MMZ in it.
 * In the original Japanese versions of the games in the Mega Man Zero series, bosses have splashes of oil flood from their bodies when split in half. This effect was completely removed from the American version because it looked too much like blood, and was considered too graphic. Suprisingly enough, the oil splashes from the Resistance members slain by the Golems and Pantheons in the first game are not taken out, leaving Mega Man Zero as the only game with "blood."
