Sephiroth reacted almost immediately as he heard the barrels. When one of them rolled out towards him he put his hands up to stop it… blinking as he saw his own left hand. His attention was drawn to it utterly at this point and he wiggled the apparatus, blinking as he saw the wrist-stump underneath.
At this point he growled, for he knew very well that it wasn’t supposed to be there. He stepped back, finding one of the building’s outer support beams, and then began to smash the hand against it as hard as he could.
WHACK. WHACK. BANG.
Metal against metal, the warehouse structure hummed every time he smashed his hand against it. It hurt him like crazy to do, but he wanted to get it off. After another thump, two of the fingers came off entirely. He poked at the gnarled mess of metal on the end of his wrist and began to pull at it, dislodging one of the hand plates that the finger hinges had been stuck in.
