Following the cancelation of Azrael, writer David Hine was given the opportunity to continue Michael Lane's story in April, 2011 with a three issue crossover event within the pages of Red Robin, Batman, and Gotham City Sirens.
Azrael returns to Gotham where he meets the crazed zealot, The Crusader, who vows loyalty to him. The Crusader claims the city is drenched in sin, deserving of God's wrath, to which Azrael agrees. In between the Angels of Death and the destruction of Gotham City stand Dick Grayson, Tim Drake, and Selina Kyle. The Crusader suggests that the three heroes were summoned there by god, and Azrael believes that they should be tested individually to see if there is one good soul, that is worthy enough to have Gotham city spared from God's wrath. Meanwhile Ra's al Ghul charges Fireball full of solar energy, turning him into a living bomb, capable of leveling the city.
The first to be tested is Tim Drake. Azrael hold's Gotham's mayor captive, while The Crusader endangers countless innocents on Tim's path to saving the mayor. The test is whether or not Tim is willing to sacrifice the lives of the innocent to save a sinner. Not willing to sacrifice anyone's life, Tim manages to save all the bystanders, and make it to the mayor in time to spare him. Azrael judges Tim with the Sword of Sin, and see's that his is truly free of sin, but before the city can be spared, The Crusader interjects, claiming he did not honor god, while he saved those trapped inside of a burning church. Not wanting to lie, and actually fail the test, Tim admits his lack of faith, and Azrael deems him unworthy of saving the city.
Selina is the next to be tested by Azrael, who has been joined by his sister, Maggie Kyle. Selina's test is whether or not she will sacrifice her sister in the name of God. Despite her sisters pleading, Selina refuses to kill her sister causing her to fail Azrael's tests.
Dick Grayson is the last to be tested by Azrael, and is confronted by an old acquaintance from his time in the circus, only known as The Prodigy. Azrael forces Dick to come to terms with his childhood sin. Back in the circus, due to jealousy, Dick allowed the Prodigy to be nearly beaten to death. Dick comes to terms with what he didn't do to help Prodigy, but claims his failures doesn't justify the destruction of the city. Dick manages to convince Azrael to use the Sword of Sin and Sword of Salvation on himself to see the truth. Azrael sees that he is actually carrying out the will of Ra's al Ghul, but it's too late to stop Fireball from detonating. The Crusader manages to contain Fireball's explosion, without any major harm to anyone, except for Fireball who lost his life. With the city safe, Azrael and the Crusader leaves Gotham.
