Riddler trophies are small '?' shaped contraptions spread around Arkham Island, Arkham City and Gotham City by the Riddler for Batman and Catwoman to find. They are small, metallic boxes made up of gears and petite generators that probably power the lights for the question mark shaped light bars into the top of them.
Incident Reports
Arkham Origins Incident
After getting all Enigma Datapacks, Batman finds a secret room with the first prototype Riddler Trophy, possibly showing that Batman had gotten Enigma's interest in riddles going again after he managed to get all the datapacks and solve the towers, and started to create his new identity as The Riddler, to further challenge Batman and prove he's the superior out of the two of them.
Arkham Asylum Incident
After Riddler hacked into Batman's communications from his hidden lair, he challenges the Dark Knight to (optionally) solve Riddles and find Riddler trophies he placed around the island. They will be marked on the map after Batman collects Riddler Maps, which were left by Riddler before he left the island. After doing all of these challenges, overheard on Batman's comm, the police discover Riddler's hideout and subsequently arrest him.
Arkham City Incident
After all criminals and Batman himself are locked up in a walled-off chunk of Gotham, the Riddler does exactly what he did six months before: hide trophies and riddles for Batman to find and solve. This time, he makes them not only hidden, but some can only be collected by solving taxing puzzles. The trophies are for not only Batman, but Catwoman as well. Catwoman's trophies are lit pink and Batman will be electrocuted if he attempts to even touch them. Catwoman, however, can collect both pink and green trophies. This time, instead of Riddler Maps, disguised Riddler goons highlighted in green must be interrogated to see the trophy locations on the city map.
Arkham Knight Incident
Riddler trophies return in Arkham Knight, while collecting some is still the same as the previous times Batman also has to use the Batmobile in order to collect and locate some of them.
