Riddle me this, Batman; What is 4 inches tall, adorably deformed, and full of questions? WRONG It isn't Justin Bieber. It's the The Riddler Pop Heroes Vinyl Figure! I suppose that was a trick question but I needed some sort of introduction to our little friend here. The Riddler is one of the few in Batman's Rogue Gallery that doesn't want to outright kill people - he's rather design some elaborate death trap that is designed to be a survival of intellect! I think I heard somewhere where he was going to release 4 inch tall Figures of himself in an attempt to take over the world but I don't think that plan ever materialized.
