Batman the Animated Series

Episode 45 "What is Reality?"

After creating havoc with computers The Riddler traps Police Commissioner Gordon mind inside a virtual reality computer program! Batman has a double task-free Jim Gordon's mind before the program kills him and solve Riddler nefarious riddle traps!

This episode abounds with numerous punning riddes -for example Riddler last riddle before being trapped in his own realty program {the strain was too much even for him!} is solved by Batman!

The Riddler was allegedly one of the hardest criminals cartoon stories to write for-supposedly the writers had to think up new riddles for him to use and Batman to solve-which is why so few featured him. Thus of the series the only real "Riddler" episodes are this one and the previous episode "If Your so Smart, why aren't you rich?"
