Evil Robot

The Evil Robot (悪のロボット Aku no robotto [http://megaman.wikia.com/wiki/Help:Japanese ? ] ) is the robot that the good cyborg Duo was fought with in the beginning of Megaman 8 and he was completely under the immense influence of the Evil Energy.

History
No one knows who or what this robot is, nor where did he come from. It is certain that he was consumed by controlled by the Evil Energy itself.

After their deep-space battle, the robot was destroyed by Duo in a battle which resulted in the two robots crashing to the planet Earth. Duo managed to damage him to the point where his body went completely inert, but the malevolent robot did enough damage to Duo where neither one could slow down to avoid burning up upon reaching Earth.

The Evil Robot's body was last seen on an old island fortress of Dr. Wily who quickly abandoned it upon the discovery of this strange android as the mad doctor found what he came for in the emergence of his new wicked scheme. Though the Evil Robot was destroyed, the Evil Energy it harnessed lived on, which is what Duo spent the remainder of the game trying to eradicate.

Trivia
Some fans refer to him as "Oud", due to his appearing almost identical to Duo's original form, albeit mirrored (opposite giant hands to Duo) and with a more "evil" looking armor and color-scheme. His head is also different, with slots under his eyes rather than Duo's T-Visor. The robot is an untouched character in terms of backstory, but important nonetheless.
