Riddler
- Voice Actor: John Michael Higgins
The Riddler is a supervillain who uses riddles in his crimes. In "Deep Cover for Batman!", Batman mentioned in his call to Commissioner Gordon that he halted the Riddler's "crossword puzzle crime spree". He makes an appearance in "Legends of the Dark Mite!" as an illusion in the Fifth Dimension. He was bowled over when Batman sent Tweedledee and Tweedledum into the villains. He also makes a brief cameo in "Mayhem of the Music Meister!".
The Riddler finally made an appearance in the episode "A Bat Divided!" when he hosted a game show called "Riddle Me This". Both Batman and Booster Gold were trapped by him. The Riddler started asking questions to Booster and for every wrong answer, Batman received an electric shock. Unfortunately for Batman, Booster wasn't very good in answering the Riddler's questions, but luckily Batman managed to escape at the last moment and help Booster defeated the Riddler and his goons.
It is revealed in "The Criss-Cross Conspiracy" that he humiliated the heroine Batwoman during a battle by ripping off her mask upon being taken down and forced her to retire. Years later, she attempts to get revenge on him when she switches bodies with Batman with the help of Felix Faust.
NOTE: The Riddler's henchman had "!", "@", "*" and "#" on their clothes, similar to the way he had "?" on his.
