Derek's 2nd Transformation

As the C-Virus infection begins to take root in Derek's body, he enters a stage-two mutation. At this stage, Derek's body resembles a gigantic dinosaur, and his musculature is quite dense. Unlike the stage-one mutation, stage-two Derek behaves instinctually instead of rationally. His driving force is to devour his enemies, and he even goes as far as to leap into the sky and attack a helicopter Ada is piloting.
