The Dark Elf soon reappears in a human residential district in Neo Arcadia. Wishing to capture it, Dr. Weil and Copy X authorise a missile to be launched at the district to incapacitate the Dark Elf. Although successful in capturing the Dark Elf, the missile attack causes thousands of innocent human casualties. Following this nefarious event, Ciel rescinds her offer to propose the Ciel System, leading Dr. Weil and Copy X to brand the Resistance as Mavericks and subsequently launch an all-out invasion against the Resistance. The Resistance is able to delay the invasion until Zero reaches Copy X and kills him once more, thus making the invasion lose steam. However, Dr. Weil then succeeds Copy X as the new ruler of Neo Arcadia and announces his true intention for capturing the Dark Elf, which is to fuse the Dark Elf with Omega and link them with a colossal frequency transmitter that would enable Omega to control the minds of every Reploid on Earth. Dr. Weil justifies this as vengeance against both humanity and Reploids for his exile in space.
