aa-1 the superior officer in charge of the armageddon was a seasoned warrior , he had fought at the battle of long-river and was there when the army of the central-zone met their end , he lost his leg in the conflict but he had his revenge when he personally executed a thousand of the enemy using only his replacement appendage , his face was scarred and there was a large metal plate covering the right side of his hairless skull , he also had his inner jaw replaced and covered in plasti-flesh but rather than the ivory colored teeth that usually were added to make a more pleasing image he had them replaced with steel projections , now when he opened his mouth it made him look like a flesh-grinder rather than human .
