WHO IS DEADLIEST!?

Brief History
When Vic Sage, a television investigative journalist, encountered stories he couldn't investigate by normal, legal means, he donned a special mask (kept in his belt buckle) that made it appear that he had no face. As the Question, Sage investigated corruption in the face of all danger, leaving a blank "calling card," which, when touched, emitted a smoky question mark. (From DC Database)
