the video game Batman: Arkham Asylum, voiced by Tom Kane. The spirit of Arkham is unlocked by scanning several tablets scattered around Arkham, supposedly by Amadeus himself. They retell the story of Amadeus euthanizing his mother, the death of wife and daughter by Mad Dog, Mad Dog's death at the hands of Arkham's guards and finally Amadeus' descent into madness. It is hinted (and later confirmed) that Warden Quincy Sharp, who believes that he is Amadeus reincarnated, is responsible for the messages as evidenced by his attempts to kill Poison Ivy, Killer Croc, Joker and Harley Quinn being recorded onto the tablets. While there is no knowledge as to how he attempted to kill them, Sharp mentions his plans to lobotomize Harley and attempt to kill Joker in his sleep, which is thwarted by the Scarecrow. If Batman scans all the tablets and comes back to the security office where he left Quincy Sharp, he will find in his place a final message telling Batman to continue his work. Amadeus' cell can also be found in the game, the entirety of its walls and floor covered with binding circles as in Arkham Asylum: A Serious House on Serious Earth. In the video game Batman: Arkham City, it is revealed that Sharp's delusions of being Arkham's reincarnation were the result of drugs and hypnotherapy delivered by Dr. Hugo Strange with the help of Mad Hatter. Scanning items related to certain inmates reveal that Sharp had treated the inmates abusively, notably by locking Mad Hatter in the physically lowest cell in the Asylum with the clear intent of him never getting out (whether he meant to kill him is unclear) and again trying to murder Poison Ivy by locking her in a cell and letting her die of her Titan overdose caused by the Joker, only for a priest covered in pollen to give Ivy the needed ingredients from the pollen to heal herself. Listening to the Blackgate inmates shows that some of them are aware of Sharp's inhumane treatments towards his patients (having occasionally been victims themselves), as well as Sharp often murdering his patients. A statue of Amadeus Arkham can be seen outside on the Arkham Asylum stage in the 2017 fighting game Injustice 2. Like most other incarnations, Amadeus Arkham is the founder of Arkham Asylum in the DC Extended Universe. He was first mentioned in Time Out Shortlist
