Dusan al Ghul was the son of Ra's al Ghul, who was rejected by his father because he was born an albino. He tried everything to earn his father's respect and eventually gave up and left. Dusan secretly returned as the White Ghost, and worked himself up in the ranks. He led a mission to use Damian Wayne's body for his father to use as a rejuvenating vessel.
Batman, Talia Head (his halfsister), Nightwing, and Tim Drake eventually stopped the process. Dusan revealed himself to everyone and offered his body to his father. Ra's reluctantly accepted and Dusan died. Faced with the betrayal of his daughter, Ra's wished that he got to spend more time with Dusan because he was the only one of his children who was still loyal to him.
