I previously reviewed a version of this Riddler by DC Collectibles here. He's the smarmy C-grade villain here with an overblown sense of superiority and intellect. He supplies all the very simple riddles and traps for Batman to waltz through, frustrating him to no end. I love how somehow he must have millions of dollars to make these elaborate traps just to secure a hostage or two, or hide a trophy in odd places. With all that money you'd think he'd be wealthy enough to create Arkham City itself!
This figure is a superior sculpt to the DC Collectibles version. Those pants aren't as weird, the face is less crazy sideways with the mouth, and the proportions are better. The paint is definitely worse though, and it has the McFarlane points that not everyone loves (flat knees/elbows, lack of paint on details, awkward ratchets and the diaper rubber crotch).
