Fan Casting Riddler (Voice) in Batman: Arkham Asylum

The Riddler was one of the many Arkham Island inmates who escaped after the Joker took control of the facility. The Riddler made his way to a hidden location in Gotham City and contacted Batman by hacking into the communication signal the Dark Knight used to contact Oracle. In order to boast his superior intellect, the Riddler had organized a series of riddles around the island, ranging from a number of small trophies hidden in out-of-the-way spots to elaborate perspective puzzles. After escaping, he challenged Batman to find these, along with the additional challenge of solving riddles that described specific objects in various rooms.
