 A dark Humvee stalks each of the Space Rangers while they re on Earth in their civilian lives. It fails to capture Andros & Ashley while they re out on a date, but succeeds in taking out each of the others. With each it runs down, they re teleported to a barren desert, with no way to contact the Megaship! Even if our heroes can put the brakes on this living vehicle, known as Tankenstein, they ll have even bigger problems with its monster form.
