Copy X

Copy X is one of the villains from Megaman Zero.

Story
Copy X is a clone of the original X, created by the scientist Ciel to take the place of X as ruler of Neo Arcadia, since X used his own body to seal the Dark Elf. However, Copy X had a different vision from the original X, and starts to hunt down all Reploids, wrongly accusing all of them of being Mavericks. The few who survive organize a resistance against Neo Arcadia, and Ciel joins them, feeling guilty for what Copy X became. His army, led by his loyal guardians Harpuia, Fefnir, Leviathan and Phantom, slowly crushes the resistance. Without more options, Ciel decides to find the lost legendary reploid known as Zero to help them in their fight. They finally find the chamber where he is hibernating, but they are followed by Copy X's forces. Ciel manages to awake Zero, who then opens the way out of the place and saves Ciel. Zero then helps the resistance, eventually defeating the four guardians and making his way to Neo Arcadia. Zero fights against Copy X and defeats him. Copy X then sets a bomb in an attempt to destroy Zero, but he fails and die in the proccess.

Much Time later, he is resurrected by Dr. Weil, who uses him on his plan to take control of Neo Arcadia. Zero challenges him and he is defeated once again, but when he tries to power himself up, a bomb that was inside of his body is triggered, destroying him completely. Weil easily takes over Neo Arcadia after this, becoming it's new ruler.

Personality
Above all, Copy X is extremely arrogant, overestimating himself and his own role as a ruler.
