History
Duane Hellman used to work at a pharmacy but was fired, for whatever reason. He didn't take kindly to his termination and he decided to get his former boss in trouble. He took a bunch of over-the-counter children's aspirins, and laced the pills with cyanide. He was caught in the act by Cloak and Dagger and was punished by spending a day in Cloak's darkness.[citation needed]
Personality
Duane was a little crazy. He was willing to hurt children, just to make his boss look bad. After his stay within Cloak's darkness, it can be assumed that he went crazier than he already was.
