Batman: Arkham Asylum
Ra's Al Ghul appears very briefly in the videogame Batman: Arkham Asylum. When Batman goes to the Arkham morgue to solve one of The Riddler's riddles, Ra's' dead body is seen. But if you return later, his body has disappeared.

Batman: Arkham City
After retrieving his body, Rā's followers took it to the underground Wonder City and used the Lazarus Pit to bring him back to life, though he was still severely bruised and barely clinging to life. While Mr. Freeze, was saved by Batman from Penguin in the Iceberg Lounge, told Batman that an enzyme is required for completing the cure, a female assassin got free and escaped. Batman understood that she was from Talia al Ghul's personal guards, and tracked her using her splitting blood, and, later, by placing a beacon on her. After Talia found Batman, he, being on the verge of death, agreed to join the League of Assassins, and to undergo Demon Trials. Although doubting, because only one man succeed, Talia allowed him to do that.

While passing Demon Trials, Batman faced Ra's. The latter proposed that Batman will kill him, and be his successor. Batman disagreed and they fought, and Ra's was defeated. Though Ra's tried to convince Batman by taking his own daughter as a hostage, Batman defeat him and freed Talia, also gaining his blood for cure. It is later revealed that Ra's is working with Strange and is the one that gave him the rescources to create Arkham City and take control of Mayor Quincy Sharp. He agreed with and was impressed with Strange's plot to gather the worst of Gotham in one area and have them all killed. However he later betrays and fatally woundsStrange after the professor was bested by Batman. With his last breath, Strange activates the self destruct and blows up Wonder Tower. Batma and Ra's jump out the window before the explosion and as Batman attempts to catch Ra's in mid air, he impales himself with his own sword to try in a last ditch effort to kill Batman, this fails and he ends up being impaled again when he lands on the main gate into Arkham City.

When Batman returns later, his body is gone, hinting that his followers revive him.
