On the way to the X series, there is a history: after ZERO fell asleep, X ended the irregular war with the help of Martha's elves, the elves were cursed, ZERO's body was stolen and turned into Omega, White Deer launched the goblin war, and X and others copied ZERO's body and put it into its real soul. After the leprechaun war, two heroes * * * were expelled from the universe, X sealed the dark elf (cursed elf) with his body, and Zero sealed himself again-Sleeping 65433. 100 years later, the human girl Xueer made COPY-X, hoping to maintain the world, but it backfired. A large number of thinking robots have been sentenced (in their words, they are afraid of another mutiny similar to the X series, in fact, they are not all thinking robots ...) Neo Arcadia's human guardian city was established (this is also the headquarters of COPY-X), and Cher sympathized with the thinking robots to live with them. But I can't avoid the attack of the new Xanadu ... Cher thinks of another legendary hero (ZERO) who is sealed, accompanied by the rebel army (the rebel army refers to the thinking robot against the new Xanadu, which is actually passable in the story, all of which are killed robots). She broke into the seal relic of ZERO (the opening picture of ZERO 1) and awakened the legendary ZERO. But he lost all his memories, but he saw their despair in Cher's eyes and helped them again and again ... Although X's body was sealed, his soul was still there. He often helped them in the form of electronic elves ... until Commander Z2 destroyed X's real body ... The dark elves were released, so Z3 came back with his Omega and resurrected COPY-X (eyes are blue). Why? ), in Z3, Zero finally knew that the body that really belonged to him was originally Omega, but X's sentence "Heart is the most important" ruined him, and X's soul could no longer stay. He entrusted ZERO with the responsibility of continuing to protect the world, and he went back to sleep in cyberspace. In Z4, White Deer tries to use the satellites of the gods to destroy the remaining life on the earth at dusk. Zero strikes again and finally destroys the white deer. Zero's whereabouts are unknown ... At this point, the zero series is over.

In the 22nd century, an "informal mechanical war" a hundred years ago made the earth a barren land. Among many insurrections in Yima, the most serious event was the space colony "Eurasia" [Rockman X5]. After many (about ten) decisive battles between X and the strongest "informal mechanical hunter" Zero, Sima was finally defeated. In X5' s story, ZERO defeated Sima with his own life, while X continued to fight with his Z lightsaber. In addition, at the end of X6, ZERO asked a scientist to seal himself off, hoping that his past would not pose any threat. In the audio drama of RTRZ album, it is mentioned that X wiped out Sima and the virus with the female elf. ) LOCKER Zero (Zero (1) [LOCKER Zero] [LOCKER ZERO] After the formal end of the informal mechanical war, X finally created an ideal and peaceful society where human beings and thinking robots exist, which is called "new Xanadu" (Neo Arcadia；; Arcadia: Land of Peace). But for some reason, X, who led this country, suddenly disappeared. Worried that X's death would cause panic, the government of Yukon Acadia ordered Dr. Cher, a talented scientist girl, to make an exact copy of X's DNA. When thinking about how to become as great as X, COPY-X unconsciously went to extremes, confused the thinking robot of New Acadia into an irregular robot and executed it for no reason. After learning about this, Dr. Cher was unwilling to lead the thinking robot that was hunted down and oppressed to form a "resistance". But she knew that resistance alone could not solve the problem until she remembered a legend: Zero, the strongest red informal mechanical hunter located a hundred years ago. Dr. cher lifted the zero sealed in the underground research institute. Because she was hunted down by New Acadia at that time, Zero, who lost her memory, was willing to help Cher. She met the fairy X who returned the laser sword, the four heavenly kings made of X gene, and attacked the core of New Acadia. After many obstacles, in the end, Britain will die with loyalty to Copy -X, and Zero also defeated Copy -X ... Rockman Zero 2 〔Idea〕] The rebels rescued a person from New Acadia, Helpy Suo [TK3/mentioned in the radio play]. When they found that they had the potential to command, they made him the commander. Because ZERO disappeared in New Acadia, the rebels were at a disadvantage, so they gathered their forces to prepare for a "just blow" to attack New Acadia. On the other hand, New Acadia also began to prepare for the event a year ago to crusade against the rebels. In order to avoid the panic of the destruction of COPY-X, Xian will assume the leadership responsibility. After wandering alone for a year, ZERO fell to the ground in the desert, and was rescued to the rebel base by the wise General of the Four Kings of New Acadia. Elbis, the new commander, was deeply influenced by Aling's reputation as a "hero" who returned to the rebel army and had an unconscious jealousy. At the same time, Dr. Schell of Daiwa is eager to develop the Schell System, hoping to avoid a "just blow" and recover the losses and casualties caused by the previous energy crisis. The "justice strike" finally failed, and the rebels suffered heavy casualties. New Acadia took advantage of the opportunity of looting in the fire and immediately launched a crusade plan: bombing rebel bases with giant flying ships and bombs. ZERO, who successfully stopped it, received another bad news: Albis has disappeared and seems to have been breaking into the high-security place "Yggdrasil" in New Acadia. After chasing Elbis several times, jealousy of the "hero" made him take two "elves" to find and remove the seal of the "Gankun Tree Top" and "Dark Elf" in the new Acadia Center, and gain the power to become a "hero". ZERO chased Elbis, who was fascinated by power, all the way to the top of Gankun tree, where X could destroy all the "dark elves" with his own body seal. Elbis destroyed X's body and released the "dark elves", but was finally defeated by Zero. Elbis, who was seriously injured, is very sorry. After the "dark elf" turned him into an electronic elf, he drifted to an unknown place ... an unknown spaceship crashed on the snowy mountain. Dr. Cher detected the same energy source as the Dark Elf. During the investigation, ZERO met a huge thinking robot "omega". When the three kings were eager to destroy Ω, a scientist who called himself "Dr. Weil" interrupted the attacks of both sides. A hundred years ago, exiled scientists announced that ω became a member of New Acadia. Suddenly, a thinking robot that looks like X arrives, challenging Zero to find the "dark elf" as soon as possible. Knowing that White Deer and New Acadia had once waged an "Elf War", Xian Jiang could not violate the meaning of COPY- X-II, so he left with everyone. Zero is the only one who doesn't know Bayrou's words "Look at how long your body can last". The reorganized rebels began to investigate the recent changes in New Acadia, and also provoked a decisive battle with Bailu and the Eighth Examiner. In order to search for the "dark elf" Bayrou, copy X, and launch missiles containing ω at human settlements, ZERO can't stop Omega from merging with the dark elf, but can only save the sage who was seriously injured by him. COPY-X-II asked Dr. Cher to separate the Cher School, but Cher really didn't believe in the Millennium. After refusing the request, ZERO was immediately designated as a terrorist by COPY-X-II. After confronting the attack of New Arouca, ZERO sneaked into the high-altitude headquarters of New Acadia-resurrected the location where COPY-X-II was located. When copy-X -II was defeated, the real fairy X appeared and told them the truth. COPY-X-II doesn't believe it. When he wanted to change, he triggered the self-destruct program set by White Deer, and ZERO was right in the middle of White Deer's trap: killing the new Aka in front of everyone. The rebels continued to search for information about Bayrou, Omega, Dark Elves and Elf Wars, and found an amazing fact: since the informal mechanical war, electronic elves have been widely used, among which the most powerful is the "Mother Elf". The ambitious Dr. Bayrou turned the mother elf into a dark elf, and used Omega and her power to kill more than half of the human beings and thinking robots on the ground, which is called "elf war" in history. Knowing the truth, ZERO vowed to defeat OMEGA, and rushed to the Power Department under Acadia, and then to the underground research institute of White Deer. After defeating the two forms of Omega, Zero landed where he woke up, facing the ultimate form of Omega-the "real body" of Zero. Beru claimed that Zero's body is actually a copy, and Omega has the real power of the Red God of War. But Zero still defeated Omega, who only had his own body but no heart. Just as the dark elves restored the combat effectiveness of Omega, the three kings jointly attacked Omega, and Elf X appeared, telling Zero the cause of the incident. ZERO finally chose his own destiny, ran to Omega with a Z lightsaber, lifted the curse of the White Deer among the dark elves, and destroyed the true self ... ZERO 4 〔Physis〕] Although Omega, the evil opposite of ZERO, was defeated, it was still Dr. White Deer who held the power of the new Acadia. Zhu Na's 1 team was attacked by Dr. White Deer's men, and Zero helped them in time, and learned that some people and thinking robots had withdrawn from New Acadia to live in the village "Zero Zone", where the space colony "Eurasia" degenerated a hundred years ago, in order to avoid the powerful rule of White Deer. ZERO observed the local natural environment for Dr. Cher. After returning to New Acadia, Dr. Beru failed to bring back the real form of Omega, and started another project-"ragnar Locke", which implied the twilight between human beings and thinking robots. He called "Ein Helga" to carry out his plan, and at the same time, he wanted to erase the old red god of war-zero. However, Kraft, the leader of the Eight Lingwu Fighters, seems to be in contact with Nego, a female war correspondent of the Zero Base Travel Team, which heats up the whole incident ... The real plan of the eight Lingwu Fighters is actually to destroy the Zero Base. After four confrontations, the rebel brigade received the news that the Biyaru army attacked the human colony. ZERO arrived at once and met Cafutong. After a round of confrontation, Negro came out to dissuade and question the relationship between this thinking robot and human beings today. Kraft was speechless and sent Juna to prison. ZERO decided to continue the pursuit and rushed into the prison to rescue Zhu Na. On the way, she met Kafka and the Millennium. When Zhu Na saw that the enemy was motionless, she immediately threw a flash bomb and cooperated with ZERO to escape from the prison. The other four eight-segment soldiers were also defeated by zero. Suddenly, the rebel brigade received a direct communication from Bailu, threatening the rebels and the gathered people. However, there is another communication intervention, which is Cafuton. He was really not angry at what White Deer did. He punched New Acadia in the control room of "Ragnarok" in space. The rebel brigade asked the headquarters to send someone to rescue the local residents immediately. At the same time, ZERO was sent to the control room of God's Twilight, and formally launched a duel with Cafton for his beliefs. Crafton was finally seriously injured, and then stopped his activities. After returning to the rebel brigade, they received news that the twilight of God would fire again. No, it's to make the whole god fall to zero at dusk. Only one person can do it-White Deer. Then A Ling went to the large transportation base in the new Xanadu and the network in the transportation loop, and got the core of Gao Ling Rona. At the top of the core part, Zero saw the battered white deer. White deer said that he was actually only a former human being, but all the people he exiled became immortal, and now White Deer wants to take revenge on all mankind. He merged with the core of the twilight of God and became a fighting form. After ZERO defeated him, he still couldn't stop God from falling at high speed at dusk. At this time, the white deer, which was not killed, appeared again and tried to blend in with God's dusk completely, but Zero could defeat him. However, the declining speed of God's dusk is no longer acceptable for activities such as transmission and communication. Zero fell into the atmosphere with the dusk of God. At this time, people saw a meteor and blessed Zero. Cher ran out of the control room and began to cry under the tree. She knew that Zero couldn't come back. The last picture of Z4 shows that ZERO has fallen into a desert, almost all his body has melted, only one helmet is still intact, and a hero's life is over. However, zero's head energy crystal has disappeared. As long as the crystal is still there, zero can be resurrected, and there is no crystal in the armor fragments. There are two possibilities: one is that zero is dead, and the other is that there is hope of resurrection. (See Rockman ZX)
