The Riddler costs 250,000 studs. Purchase him and switch to him in the Bat Cave Trophy Room.
(copied from the xbox 360 guide)
You can’t use The Riddler (1966) version for this achievement; it has to be the modern version.
To unlock The Riddler, you'll have to six quests in the Hall of Doom/Justice for him to show up.
- ‘The Best Laid Plans of Bats and Men’ (Hall of Doom)
- ‘Think Bike’ (Hall of Doom)
- ‘Five Studs, Please’ (Hall of Doom)
- ‘Tricky Tour Guide’ (Hall of Justice)
- ‘Nightwing of Fire’ (Hall of Justice)
- ‘Tripple Riddle’ (Hall of Justice)
To complete his quest, there are three riddles to solve. Refer to the video below for guidance. After they are completed, he will unlock and can be bought for 250,000 studs.
Once you have The Riddler purchased, fast travel to the Batcave then to the Trophy Room. Right when you enter either switch to The Riddler or play as him entering and the achievement will unlock.
Video by LukaLaurent:
This has to be the regular Riddler, not the 1966 version and must be done in the Batcave trophy room and not the Watchtower Trophy Room. The regular Riddler first appears during Mr. Mxyzptlk's second mission in the Batcave Trophy Room, and later has his own mission in the Hall of Justice. The Riddler's mission in the Hall of Justice is the very last mission there, once you complete you can purchase him for 250,000 studs. Once you have unlocked and purchased him head to the Batcave Trophy Room and switch to him, once you do the trophy will unlock.
