The character's origin story recounts that the Riddler, whose real name is Edward Nigma, becomes fascinated with puzzles at a young age. After a teacher announces that a contest will be held over who can solve a puzzle the fastest, Nigma sets his sights on winning this, craving the glory and satisfaction that will come with the victory. He breaks into the school at night to practice the puzzle until he is able to solve it in under a minute. Due to this he wins the contest and is given a book of riddles as a prize. His cheating rewarded, Edward embraced the mastery of puzzles of all kinds, eventually becoming a carnival employee who excelled at cheating his customers out of their money with his bizarre puzzles and mind games. He soon finds himself longing for greater challenges and thrills and dons the disguise of the "Riddler" to challenge Batman, believing him to be a worthy adversary. In his first encounter with the Dynamic Duo, Riddler first tried to confound the crime-fighters with his infamous double-entry Riddle Clues and then tried to kill them both in a booby-trapped glass maze on a pier, sealing the door so they couldn't leave the structure before it exploded, only for Batman and Robin to escape and the Riddler "vanishing" after getting knocked into the sea by the explosion, leaving only his trademark "?" floating in the water.
