1. Azrael
By Azrael, I mean the original Azrael, Jean-Paul Valley Jr. More of a tragic anti-hero than an out and out villain, Azrael was originally conceived as a test-tube baby and was trained by the Order of St. Dumas, after misreading his dying father's intentions to allow him to escape their influence. Azrael eventually rejected the Order's violent methods in favour of Bruce's more caring crime-fighting techniques, after saving Bruce from his father's killer. In Knightfall, the comic series that The Dark Knight Rises borrowed many elements from, Bruce is training Azrael to be his successor if anything should happen to him, only for Bane to then break Bruce's back, forcing Azrael into action earlier than anticipated. Unfortunately, due to the psychological conditioning he has been unknowingly subjected to during his life by the Order, Azrael soon became obsessed with improving his crime-fighting abilities, modifying the Batsuit to make himself a much more formidable foe, and is even capable of defeating Bane. Unfortunately, his conditioning leads to him becoming extremely violent, and he allows the death of various people, as well as shunning Robin, and Commissioner Gordon. When Batman hears of Azrael's methods, he returns and eventually defeats Azrael after a lengthy battle, who then leaves, acknowledging Bruce as the only true Batman. I must admit I half-expected this to happen in The Dark Knight Rises as soon as I heard that Bane was going to be a major villain in the film, and that Joseph Gordon-Levitt was playing an unnamed role. I thought Levitt would take on the role of Azrael, taking over the policing of the City once Bane had broken Bruce, but alas it was not to be and the film turned out great anyway, but I can't help but imagine what it could have been had they followed this storyline further, although maybe it was just too much to steal from Knightfall for Nolan to seriously consider going this route with the story. One thing is for sure though, if Nolan had chosen to include Azrael, he would have had an interesting twist, and who's to say that Joseph Gordon Levitt's Robin wouldn't have eventually turned out this way, prompting Bruce to return to Gotham. It would have been a great way to cut out the middle-man, in this case Azrael, whilst keeping Nolan's original word that he wouldn't make a film that included Robin. So, that's who I think Christopher Nolan could have faithfully recreated on the big screen in the perfect way. Agree or disagree? Am I missing anyone you think could have fitted into Nolan's world perfectly? Let me know in the comments below!
