Mega Man Zero 3

Story

With Ciel's resistance, he defeated Copy X, the ruler of Neo-Arcadia. The terror of the Neo-Arcadian regime ended, but energy shortages remained a constant problem. Ciel devoted himself to researching new forms of energy. And Elpizo became the newly appointed leader of the resistance. But overwhelmed by his desire for power Elpizo awakened the dark elf whose magic had once nearly destroyed the world. Elpizo, thirsting for the dark elf's power, lost sight of his true purpose, and was finally defeated after a fierce battle. But the dark elf fled, its destination unknown.... The battle for the dark elf had just begun. Two months after the events of Mega Man Zero 2, a spaceship that recently emitted energy similar to that of the Dark Elf crashes. Zero, Ciel and a few members of the Resistance set out to investigate it. Shortly after the mission begins, Ciel and the two resistance members are captured by Neo Arcadia when Zero enters the ship. However, they are neither injured nor held captive when an incident breaks out with a giant reploid named Omega that not even Leviathan and Fefnir can handle together. Zero interrupts the fight and has to take matters into his own hands. Shortly thereafter, Dr. Weil shows up, with a seemingly restored Copy X in tow, and reclaims leadership of Neo Arcadia, much to Harpuia's chagrin.
