Following the invasion of Gotham City via Azrael and his Angels of Death, Red Robin teams up with the new Batman, Dick Grayson to fight against Azrael. Tim is tested by Azrael to see if he is able to save the lives of innocents, a test which he, like Dick, ends up failing. At the end, it is revealed that in revenge for destroying the base of the League of Assassins, Ra's al Ghul was manipulating Azrael to get him to face off with Red Robin.
