I had to watch several gifs to fully see it, but when Vash loaded the nuke gate cube into his gun as the 'ammo,' he took all the matter of his left prosthetic arm away (leaving an empty sleeve behind) to form the shape of the Angel demon? Arm onto his right. Fusing together all 3: his left arm, right arm, & revolver into a literal massive Tri-Gun. ;o;

(And he consciously chose and figured out how to do all of this with his Plant powers, right on the spot while asserting his own agency!)
