Dr. Charles Elias Walker is a U.S. metahuman (unknown) and the former assistant head of metagene research at TriVext Corporation in Thunder City. He is a slim man about five feet and eleven inches tall, with black hair and blue eyes and a slight five o'clock shadow.
Walker had worked at TriVext in Thunder City as the assistant head of metagene research under Dr. Zachary Knell until September, 2001. He was then transferred to TriVext's Chicago branch because that city contained more metahumans per capita than any other place in the world. Walker, who was prejudiced toward metahumans, learned before leaving that he carried an active metagene.
