Ra's al Ghul (Arkhamverse)

Batman: Arkham Asylum
Ra's al Ghul's name is also written on a toe tag of a corpse in Batman: Arkham Asylum, playing on the fact that he is immortal. The body lies in a vault in the old Arkham Mansion, where it mysteriously vanishes towards the end of the game. The nametag of the dead body is seen on the floor near the open morgue door.

Batman: Arkham City
After being exposed to the Titan Poison that is slowly killing the Joker, Batman is shown a DNA strand by Mr. Freeze that is needed for the cure to become functional. Batman quickly realizes that the DNA is a match for Ra's al Guhl and, via a tracking chip he placed on a member of the League of Assassins, sets out to find him. His search leads him to the remains of Wonder City beneath Gotham where he is reunited with Talia. Near death and knowing that he must see Ra's, agrees to undergo the Trials of the Demon and speaks to Ra's first on the spiritual realm.

After emerging from his Trial, Batman proceeds to the final test where he must kill Ra's himself and assume leadership over the League of Shadows. Ra's is overjoyed to see that Batman will finally take his place as leader of the League; nonetheless, Batman reveals that he has doublecrossed Ra's and that he will not kill him. Batman and Ra's fight one another until Talia intervenes, where Ra's quickly threatens the life of his own daughter. Angry at both Talia storms off and Batman gets his blood sample from Ra's, quickly delivering it to Freeze for analysis.

Ra's, while initially fearful of continued use of the Lazarus Pit returns once Protocol 10 has been implemented in Arkham City and joins Batman and Hugo Strange in Wonder Tower in the center of Gotham. There it is revealed that Ra's was behind Arkham City all along and provided League resources to its development so that crime could be eradicated in Gotham. With Strange having outlived his usefulness, Ra's stabs him in the back with his sword and looks out on Gotham as it burns. Strange is not dead and engages Protocol 11, which Ra's was unaware of. The Wonder Tower explodes via a self destruct protocol, but not before Batman and Ra's were able to escape.

Ra's and the Dark Knight continue to struggle with one another as they fall from the destroyed Wonder Tower. Ra's, defeated, sees his only avenue to win as plunging his sword through his own chest and into the Batman. Nonetheless, Batman has anticipated this attack and is able to pull away in time. Batman glides to safety while Ra's is further stabbed when he lands in metal debris. Later, however, the body has disappeared from the site with no trace. Presumably Ra's was recovered by the League of Assassins and returned to the Lazarus Pit beneath Arkham City due to the increased guard presence in Wonder City and the lockdown of the League areas.
