The Riddler possesses extreme originality in decoding and formulating puzzles of all kinds. His deductive ability has perfused his new role of private detective, in which he is shown to have investigative skills that rival those of the Dark Knight. The Riddler has no superhuman abilities, but is a highly cunning criminal strategist. He is not especially talented in fisticuffs (although his endurance has grown from having to engage in them over the years), but sometimes employs weaponry that exploits his gimmick, such as exploding jigsaw pieces, his infamous question mark cane, known to house a wide variety of technological devices and weapons, and question mark shaped pistols. He is shown to be skilled with engineering and technology, confronting Batman and Robin with unique and elaborate deathtraps.
The Riddler is a super-villain enemy of Batman who commits crimes revolving around an obsession with riddles. His mental psychosis results from a deep inner need to prove that he’s smarter and therefore better than others, which causes him to leave challenging clues behind in otherwise perfect crimes. This psychological compulsion has resulted in him being repeatedly imprisoned in Arkham Asylum. Despite this obvious flaw, he is otherwise an extremely intelligent criminal mastermind. He has been associated with the Legion of Doom and the Secret Society of Super-Villains.
