There seems to have been a lot of thought to making a coherent whole out of this. Looking at the way the components are arranged...
Chrono Miner - becomes the torso and left shoulder IFV - becomes the right shoulder, with launcher, machinegun, and repair arm attachments mounted to different shoulder points Grizzly Tank - becomes the left arm, turret attaches to the shoulder Robot Tank - splits to become attachments on the wrists Mirage Tank - becomes the head Prism Tank - becomes the waist and upper legs Battle Fortress - splits into the legs and feet
