Elf Wars

The Elf Wars is a four year long conflict that took place in the end of the Maverick Wars. This period is referred as the Elf Wars because many Cyber Elves were used during the war.

Doctor Weil cursed the Mother Elf, turning her into the Dark Elf, and used her to create several copies known as the Baby Elves. Using the Baby Elves, Dr. Weil was able to amplify the power of several Reploids and control them at will, unleashing an attack to the world with them. Dr. Weil also took the original body of Zero and created Omega, the "Devil Reploid", and planned to combine Omega with the Dark Elf to be able to control all Reploids in the world. Zero's brain (or soul) wasn't in his body, and he was given a new body to help in the fight against Weil.

In the end of the Elf Wars, X and Zero defeated Omega with a Final Strike and Weil was stopped before he could combine Omega with the Dark Elf. Due to his actions, Weil was banished from the newfound human utopia, Neo Arcadia, and Omega was sent to space. Approximately 90% of all Reploids and 60% of all humans had perished in the Elf Wars.

After the Elf Wars, Zero sealed himself again, (later being found by Ciel in Mega Man Zero). Sometime after Zero's seal, X found out that the Dark Elf was too dangerous to still be in the world, so he sealed the Dark Elf with his own body (as shown in Mega Man Zero 2.).
