Riddler Trophies are the most numerous collectibles in the game, with 243 scattered across Gotham. They come in various forms: physical trophies, riddles (requiring you to scan a specific object), and environmental puzzles (often involving the Batmobile or specific gadgets). Finding them all is necessary to unlock the final confrontation with the Riddler. Use Detective Mode to highlight them and consult your map for general locations. Some require specific story progression or gadget upgrades to access.
