Derek's 1st Transformation

After Derek Simmons is injected with an enhanced C-Virus, he enters a stage-one mutation. At this stage, his upper body maintains a humanoid appearance, and his violent tendencies are amplified. He has yet to lose his sense of self. His legs, however, transform into something beastlike, and he is powerful enough to outrun a high-speed train. He can also use shards of his bone as projectiles, and can fire them off with deadly accuracy. Any bone matter lost in this manner is regrown thanks to the effects of the C-Virus.
