Project Elpizo

Project Elpizo, also known in Japan as Project Elpis, is the name for Dr. Weil's operation to combine the Dark Elf with Omega to exert complete control over all Reploids.

Origins
Near the end of the Maverick Wars Dr. Weil, a member of the humans researching Cyber Elf, proposed “Project Elpizo,” an operation to create Omega, a Reploid that’s a perfect ruler using the Mother Elf’s program rewriting ability. X opposed this operation, but out of fear of a long-lasting war support began to build up for complete control of Reploids. The human leadership’s “philosophy of rule” confronted X’s “philosophy of coexistence”. Around that same time, Dr. Weil's action started the worst war in history, the Elf Wars, by using Baby Elves to completely control Reploids at will and making them fight amongst themselves as if Mavericks. Concerned over the Elf Wars himself, X formed the "Neo Arcadia" organization for the sake of providing protection for the humans. Rather than exercising control by using the Dark Elf, X successfully used his "reputation" to invoke order.

At the closing of the Elf Wars, Dr. Weil completed Omega, but was unable to finish Project Elpizo as X and Zero had captured the Dark Elf. Omega ended up betraying the human leadership under Dr. Weil's orders and attacked both humans and Reploids alike. Though he had an army of Neo Arcadia's great Mechaniloids Golem by his side, Omega was defeated by X and Zero while the Reploids controlled by the Dark Elf ended the war.

In the aftermath of the war, Omega was ejected into space, and Weil was banished from Neo Arcadia as a criminal. At that time, deceiving the whole world to protect their reputation, the pro-mankind utopic nation buried the "human" Weil's grave sin into history's darkness without revealing it. After a very long time, even Neo Arcadia entirely forgot about the risks Weil took.

Predule
100 years later, Neo Arcadia organized the Administration Bureau and the Hunters to conduct a large scale survey into a newly-discovered information facility from the previous age; the Sunken Library. The survey was supervised on-site by Harpuia as X's administration from the scientific branch. Though Harpuia's orders were to avoid independent action and report any situations to the accompanying Hunters, a Reploid of the administration bureau, TK-31, wandered off on his own. As if guided by something, he ended up in the deepest data room. There he discovered fragments of history sealed away in the darkness, information he had never heard off or seen before and he was completely enthralled. Through seeing a record, the truth would spread out unbidden before his eyes. TK-31 saw the power that nearly led the world to destruction, Dark Elf; the above-first-degree war criminal Dr. Weil; the end of the Elf Wars; the operation to completely control Reploids, and X fighting alongside others against Omega. Seeing these events reminded him that the research facility in Area 7 stores the Baby Elves from the time of the great war. An alarm went off and the record rewound itself in overflow. Subjected to all this information, TK-31 saw the Maverick Wars, the Sigma Antibody Program Mother Elf, her light saving the world; calling it the birth of hope, he mistakenly concluded: "This is Project Elpizo". Hearing the alarm, Harpuia arrived on the scene and ordered TK-31 to forget everything that he saw.

During the following week, Neo Arcadia made the energy distribution quotas for the serial-number Reploids stricter and the Maverick arrest rate rose with an unprecedented 8%. Amongst the Reploid there was a lot of talk that there were no abnormalities in the group that was retired and that another group managed to escape and staged an armed uprising, forming a Resistance. Meeting with HE-22, another Reploid of the administration bureau, TK-31 learned about this situation and is informed that mysterious and dangerous things are happening to the Reploids involved in the survey and that the submerged city was deleted from the records. Before HE-22 could get his entire point across, the Hunters showed up and designated TK-31 as a Maverick. Caught by complete surprise, TK-31 was forced to flee along with HE-22, who revealed himself as a member of the Resistance trying to recruit TK-31 as an indispensable ally in helping free his comrades who would be retired under false pretenses. Though TK-31 agreed to join the Resistance, he insisted on first wanting to figure out what was going on in the research facility in Area 7. HE-22 was reluctant and tried to talk TK-31 out of it, to which TK-31 however responded that HE-22 should stop calling him by his serial number. Declaring that his name is really "Elpizo", after the project mentioned in the records, he ironically proclaimed that he was chosen to become the hope of all the Reploids being oppressed in Neo Arcadia, unaware of what Project Elpizo truly was.

Epilogue
Afterward, Elpizo became the leader of the Resistance. However, a crushing defeat at the Four Guardians' hands left him craving for more and more power. Eventually seduced by the power of the Dark Elf, Elpizo ended up breaking the Dark Elf's seal, and setting in motion a chain of events that allowed Dr. Weil and Omega to return from exile, once more starting up the operation to control all Reploids. Though Weil initially once more used the Baby Elves, they were no longer needed once Omega managed to capture the Dark Elf and became "absolutely perfect". Using Omega and Dark Elf, Dr. Weil started brainwashing all the world's Reploids. However, Omega's brainwashing had no effects on X, Zero and the Four Guardians, who joined forces against Dr. Weil and Omega. Though successful in stopping the operation, the Four Guardians gave up their lives, and X used up his energy, unable to manifest in the physical world any longer, for the cause and Zero's final battle with Dr. Weil would still be ahead of him.
