'The Question' ('Vic Sage') created by writer/illustrator Steve Ditko, debuted in Charlton Comics' Blue Beetle #1 (June 1967), followed by Charlton's "Mysterious Suspense" (October 1968) .
The character was then acquired by DC Comics in the early 1980's...
...and incorporated into the 'DC Universe', with former 'Gotham' police officer 'Renee Montoya', a protégé of Sage, becoming the new 'Question'.
"...in 'Hub City', TV investigative journalist 'Vic Sage' looking into criminal activities by a 'Dr. Twain', was approached by 'Aristotle Rodor', a former college professor, telling Sage about an artificial skin he had developed with Twain called 'Pseudoderm' with sometimes fatal side effects.
"Rodor and Twain agreed to abandon the project and parted ways, but Rodor discovered Twain had decided to proceed with an illegal sale of the invention to Third World nations, regardless of the risk to human health.
"Sage resolved to stop him but had no way of going after Twain without exposing his identity. Rodor suggested Sage use a mask made of 'Pseudoderm' to cover his TV-famous features. Armed with a foolproof disguise, Sage caught up with Twain, leaving him bound in Pseudoderm. On television, Sage reported on Dr. Twain's illegal activities.
"Sage decided this new identity would be useful for future investigations, and partnered with Professor Rodor, who supplied the Pseudoderm and eventually modified the bonding gas to change the color of Sage's hair and clothing..."
