He's finished! I also created a little backstory for him and the other two: Being sick by the more and more victories of th humans, Meca One (the original one) decided to take the battle into his own personal hands. He took his personal resources and modified himself and his last two Generals into living battle machines to unleash the full power of his wrath on Exo-force.
