Despite being one of Batman’s oldest foes, the Riddler remains one of the more underrated by the other members of his Rogues Gallery. He has no discernible physical strength and for all intents and purposes, he’s just super smart and good with riddles. He’s not overly psychotic (although he has those moments) and he’s definitely not that physically strong or imposing. Recently, however, he was beaten and left for dead by Poison Ivy, who similarly doesn’t fall far on the physical strength meter.

He kidnaps his old boss and locks him away in a live-action version of his game; "The Riddle Of The Minotaur.” While the Caped Crusaders save the day, Nygma’s old boss is left paranoid, sleeping with multiple locks and a gun under his bed, fearful that the Riddler might return.
