Quizmaster sketch

The Anti-matter Riddler from a world morally reversed from our own. He fronts a group of crimefighters called the Justice Underground.

Technically not the Riddler, they're still one and the same, whose actions are goverened by his other self.
When the Riddler becomes a good-guy, the Quizmaster becomes a villain.

I've just started to read the 'Trinity' series.
