The Knight reveals himself as Jason Todd, the previous Robin, who was tortured and seemingly murdered by the Joker, and has since been left traumatized. Todd blames Batman for abandoning him, and escapes after refusing Batman's offer to help him recover.
Potential theories are as follows: Jason Todd - The Arkham Knight, now know as the Red Hood, was never apprehended following the events of the game, and in keeping with his vigilante tradition, he may have taken up fighting villains in Batman's stead.
He was revealed as Jason Todd, formerly Robin before the Joker's torture at Arkham Asylum, but later abandoned his Arkham Knight persona when he realized Batman's trust and became the vigilante known as the Red Hood.
Azrael then told Batman that he deserved to be his rightful successor, if ever Batman should perish, and informed him that he would follow Batman's code not to kill, and handed his sword to him in the process.
No matter what universe he's in, Batman always goes through major life-threatening scenarios, with the events of the Arkham franchise truly pushing the Dark Knight to his limits. But despite that, there can no longer be any doubt that Batman survives the ending of Batman: Arkham Knight.
The game Batman: Arkham Knight opens with the Joker's body being cremated after his death in Arkham City. Fans of the game who played more than once know that there's a secret scene where, when the player begins New Game +, the opening scene of Joker's cremation changes.
In the end, Batman convinces him to abandon his quest for revenge against him and Todd then turns into the Red Hood. All-in-all Rocksteady's version isn't bad but they do leave some questions out there... like when exactly Joker captures and tortures Todd over the course of a year in Arkham Asylum.
Azrael is a name given to the champions of the amoral Catholic extremist guild, the Order of St. Dumas. Azrael acts as the deranged agent of the Order, often serving as an ally and enemy to Batman due to his violence, diluted moral-system, and homicidal tendencies.
In gameplay, Azrael plays exactly like Batman, although he has less gadgets in Predator Mode. Playable in Batman: Arkham Knight. Unlocked by default from the start of the game. Appears in Batman: Arkham City, and Batman: Arkham Knight.
Jason was thrust into the world of heroes and villains by Batman. If he were to kill the Joker, Batman would feel a level of responsibility for that. Also, a major theme of Batman, in virtually any medium, is guilt. Batman doesn't want Jason to have to bear the guilt of killing the Joker.
In the final chunk of Arkham Knight's story campaign, Batman's secret identity is revealed to the world at large and the Dark Knight tells Alfred to activate the Knightfall Protocol. The cutscene (via the RabidRetrospectGames YouTube channel) below shows what happens when players do everything to be done in the game.
In the DC Universe, few characters are as divisive as Red Hood. He's not a traditional hero, nor is he a villain. Instead, he occupies a gray area, using his skills and his willingness to break the rules to fight crime in his own way.
Given that Brainiac is the main villain of Suicide Squad, since he seems to have taken control over the Justice League members, there is a chance that somehow Brainiac is the one who brought Batman back to life.
If Ra's is restored to health, he would most likely resume his command over the League of Assassins and continue waging war with whomever he sees as a threat, including Batman: Arkham's other villains. Although this decision would lead to his good health, it would also lead to countless more lives being lost.
Gotham City fascinates Bane because, like Peña Duro, fear rules Gotham—but it is the fear of Batman. Bane is convinced that Batman is a personification of the demonic bat which had haunted his dreams since childhood. Therefore, Bane believes fate placed Batman on a collision course with him.
Azrael—otherwise known as the steadfastly religious Jean-Paul Valley—is most well-known for being a Batman fill-in during the 1990s. But Azrael's origins are much stranger than Batman's; Valley was brainwashed by the Christian group the Order of St. Dumas into believing he was God's avenging angel, Azrael.
While originally an ally and even apprentice of Batman, Azrael was the one to adopt the Batman moniker following the Dark Knight's crippling defeat at the hands of Bane. Following this he revealed his true colors as a mad zealot in his blind massacres of criminals and those in his way, making him an enemy of Batman.
The name Azrael is both a boy's name and a girl's name of Hebrew origin meaning "help of God". This is the name of Angel of Death in Jewish and Muslim tradition, not a great start for an innocent child -- or a great role model for a teenager.
If you break the sword, azreal says he is no one's pawn and goes after the people who experimented on him. I thought you had to take the sword anyway before you can make the choice. *Azrael breaks the sword and leaves through the elevator, swearing to destroy St. Dumas for brainwashing him like they did.
TLDR: Superman didn't save Jason because he was being tortured by Lex Luthor at the time in order for Luthor to create Conner Kent/Superboy . This is why he wants nothing to do with Superboy once he appears.
After six months of torture, the Joker finally ends his video series by shooting Jason Todd in the chest, leading Batman to believe that his protégé had been killed. However, it is later revealed that the Joker had made Jason Todd wear body armor during the shooting, and that he had indeed survived.
