There really is endless amounts of poses you could do with this guy.
In chronological order:
-SWAT shootout (using handgun)
-Blasting T-1000 pointblank with M16
-Hasta La Vista (if they do a liquid Nitrogen T-1000)
-McFarlane/my sig pose
-Locked in struggle with T-1000
-punching/T-1000 morph scene
-Hand caught in giant gears, attempting to free himself
-carving T-1000 in half
-getting beaten up by T-1000 with metal rod
-being rammed by steel beam
-crawling/T-1000 impaling him through floor
-firing last grenade shot into T-1000
-shaking hands with Sarah Connor
-being lowered on chains
Of course some of this is very dependant on having props and set dressing to more properly recreate the scenes and in the absence of such things it might not be worthwhile. And no I won't be buying a T-800 for each and every scenario I've listed. Because that'd be just mental
