After years of training under "The System" Bruce's turn to assume the mantle of the avenging angel Azrael has come. Thomas Wayne as his father before him, have all worked as agents for the Order of St. Dumas. Azraels are the organization's angels of death, distributing vengeance for generations to those who betray or threataned the Order.
Thomas, or rather him in his other identity, is sent to "deal" with a particular immortal character who plans to take over with his own massive organization. This character has lived longer than the Order of St. Dumas-In fact, he was one of St. Dumas own rivals: In The Crusades!
Thomas in his Azrael guise kills his target's beloved wife instead and a hunt for Azrael's head begins. After months of evading and killing members of League of Assassins who are after him, Ra's Al Ghul hires the most efficient assassin.
As a 19 yr. old Bruce finds his father dying in the underground cave beneath their mansion, Thomas lies dying from wounds inflicted by the hired gun, Deathstroke! All of Alfred's medical attention does nothing to heal Thomas. Both servant and father now speak the words to awaken the avenger within Bruce.
Adopting the guise of Azrael Bruce seeks out his father's killer, confident the years of training of "the system" will help him. Upon catching Deathstroke, an impressive battle ensues with Deathstroke as the victor losing an eye, and Wayne barely escaping with his life. This motivates Wayne to further his training all over the world and returns 5 yrs later, discovering Deathstroke was hired by the Demon's Head himself: Ra's Al Ghul. If Wayne is an "angel" and Ghul a "demon" a massive war awaits!
