1. Puzzles that stump Batman

   Strong evidence

   Series-wide

   The Riddler's riddles and traps are designed to challenge the world's best detective, and in many stories they do. Creating a puzzle that works requires a good model of the solver. This is the clearest evidence for deduction and invention in his profile, even if the comics make the puzzles easy for the reader. Outwitting the world's best detective, even briefly, is a rare achievement among his peers.

2. Learning Batman's identity

   Moderate evidence

   Hush storyline (2002-2003)

   In one well-known storyline, the Riddler works out who Batman is and uses the knowledge in a larger scheme. It is a strong demonstration of deduction from indirect evidence. The knowledge is later lost or ignored in continuity, so we count it as moderate. He reaches the conclusion by combining many small pieces of information, which is the kind of reasoning we look for. The continuity problems reduce its weight, but the underlying display of deduction is real.

3. The Box

   Moderate evidence

   Batman Forever (1995)

   In the film, Nygma invents a device that reads and absorbs the thoughts of viewers, and uses it to grow rich. It demonstrates invention, though the film leans on spectacle. The film portrays him as an inventor who is mistreated by his employer, which is a different angle on his intelligence. The device is the best example of his inventiveness.

4. A killer who exposes corruption

   Strong evidence

   The Batman (2022)

   In the film, the Riddler leaves a trail of coded messages that expose the city's secrets. The plan requires research, patience and an understanding of how people respond to puzzles. It shows a capable planner, though the film also shows him as a man of limited social influence. The film makes him a darker figure than earlier versions and gives his puzzles a purpose. The scale of the plan, with its many stages, is the main reason we rate this as strong evidence.

5. Puzzle challenges in the games

   Minor evidence

   Batman: Arkham games

   In the Arkham games, the Riddler fills the city with trophies and riddles. The scale suggests careful planning and a lot of preparation. The games use it as a mechanic, so we count it as minor evidence. The sheer number of trophies and riddles hidden around the city requires planning on a large scale, and the quality of the clues varies from simple to demanding. The games present it as a challenge for the player, so we count it only as background support for his obsession and ability.

1. Compulsion to leave clues

   Series-wide

   His need to announce a puzzle gives Batman the information to catch him. A top strategist would keep silent. This is the clearest limit on his foresight. Batman exploits the habit repeatedly, following the clues straight back to him.

2. Repeated defeats

   Series-wide

   The Riddler is beaten by Batman, and sometimes by lesser opponents, many times. Part of that is the structure of comics, but the pattern counts against the highest numbers. Tellingly, he rarely changes his approach.

3. Different versions

   Series-wide

   The character differs across comics, films and games. We use the best-known versions and average them, so confidence stays at medium. Some versions are far more dangerous than others, so we use a middle estimate and treat the most extreme portrayals with caution.
