[@Subject Zero]Not neccesarily duplication as much as splitting himself into weaker biological constructs running on a hive-mind. Only the main body can fully change, and they all take body mass away from him, leaving him fast, but weakened in a sense of raw strength and durability. The hive-mindis great for coordinatimg defense and sneak attacks,as well as keeoing an eye on his own battle from multiple angles, but it can get distracting if one of the two isn't sitting still.
