I can totally see your buddy TJ walking through a con, stopping to look at a gal in a Slave Leia outfit or something equally transfixing. Then a little kid comes up beside him unbeknownst at first to his presence, but when the kid reaches up to touch the robot hand, TJ's real hand whips out from beneath his cloak slapping the little kid's hand away and grabbing him by his shirt. "Nothing there but trouble boy!" he says and pushes the kid aside.
Wait, wrong movie franchise. Oh well, it be fun to see the reaction of a gloved real hand reaching out to those unaware! Especially if it held an igniting lightsaber!!
Great job on his costume BobaFuss!!!
