The original concept 'ARMM' Spartan stands for Advanced Robotic Modular Manipulator. His right arm/hand is removable so that different units can be attached to it. He was made from a Halo Reach Jorge figure, the right arm of movie Scorponok, a Fox Robot hand, and spawn interlink cannon. Powerful rare earth magnets attach the two hand units and make them removable. Can you spot the other part of transformers scorponok? I retooled his head and make it the chest plate! His right shoulder pad came from an Arctic assault Iron Man and left one from a Batman Armory DC Direct figure.
