When is a Riddle not a Riddler?
Riddle me this, Robin!
Who sings for Nightwing?
Friend or foe?
The Riddler. He's a constant thorn in Batman and Robin's side who always
teases the Caped Crusader and Boy Wonder with enigmas and questions
pertaining to his master plan, but is the Riddler truly a villain or a
hero? Can the king of conundrums turn over a new leaf to become a master
detective and crime-fighter himself?
