So the former Firebender who's gonna die = Joker?

Talk about your tortured associations. It requires knowledge of not one, not two, but THREE unrelated series: Avatar: The Last Airbender, Batman Beyond: Return of the Joker, and Young Justice.

Plus the link is extremely tenuous between Mark Hamill and Young Justice.

Anyway I think it's highly unlikely at this point. Nightwing has just turned 19. Jason is younger - perhaps 17. 16 even, at time of death. He couldn't have taken Ozai with him.
