As Drax glides in to strike his double, the double strikes him on the head.
"Point to the defender," says the voice behind Drax. A third flag unfurls in the dopplegangers side of the arena and the fight is over. With a grin, the doppleganger melts back intot he sand of the floor. Drax turns and sees, the weapons he laid on the arena floor also being sucked down. And then they too are gone.
The torches go out and Drax is alone in a crumbling fighting arena.
