Fan Casting Ras Al Ghul in Batman 5: Knightfall

Essentially surfaces to form an alliance with the Bat Team to bring down Elliot/Dusan as Elliot has challenged his leadership for the League of Assassins as well as Elliot/Dusan losing control and growing more unstable (due to prolonged exposure to a corrupted version of Lazarus) and beginning to go too far than what Ras had intended for Gotham (Elliot would have no qualms about slaughtering more than just criminals, but the usual stuff, killing kids, innocents e.t.c)
