Derek's 3rd Transformation

Derek's body continues to mutate, and he enters stage three. Derek's humanity is completely gone at this point, but his survival instinct remains. He ingests multiple corpses in order to give his body the organic matter needed to assume this form. This new, hideous form resembles an amalgation of multiple insect species. When stage-three Derek loses a limb or other body part, he can regenerate it by ingesting more corpses. He could in theory live forever as long as there are corpses for him to ingest.
