Batman: Arkham - Ranking EVERY Villain Worst To Best

With Talia dead and Ra's on his last legs - for real this time - it's not surprising that the other daughter of the Demon would show up to try and sort things out.

The return of Ra's al Ghul in Arkham Knight's Season of Infamy expansion sees Nyssa leading a rival faction against those loyal to him, trying to prevent him from accessing the Lazarus Pit and regaining his strength. She offers Batman a choice: to side with her and prevent Ra's from rising again, or to help Ra's and face the consequences.

If you choose to accept Nyssa's offer, Batman destroys the Lazarus Pit, and convinces Nyssa to let her father die naturally, despite her wish to kill him herself. But if you give Ra's the Lazarus, he swiftly kills his daughter and disappears in a cloud of smoke.

Though highly dangerous and volatile, Nyssa is not really evil. Allowing Ra's to die results in her promising to disband the League, after which she and her followers leave Gotham, never to return.
