You could film some critters (scorpion, snake,... comes to mind) doing their thing out in the desert area, when some super secret government jet (that just happens to be flying by), has troubles and leaks a little of it's super rejuvinating/self healing chemical, before it rejuvinates and self heals of course. When the drips hit the dust (zoomed in and in super slow motion of course), things happen to what ever gets hit. The scorpion and snake that were on an old abandoned truck chassis get rejuvinated into a VX! Maybe different things become different VX's?
Just a thought??? Hey, you asked! :grinr:
