This is my personal opinion here are the villains i would love to see in the Batman Reboot.
FIRST FILM:
Owlman:
I really like the charcter of Owlman. As for his back-story he could be Bruce Wayne's younger brother who wasn't there at the time of his parent's death. Due to the death of his parents he drives a wedge between him and Bruce. In the end he leaves Gotham for good at age 18 and meets The Court of Owls who train him in combat. 17 years later he goes back to Gotham in order to assist the Court of Owls's take over of Gotham. He takes on the identity of Owlman and later battles his brother multiple times throughout the film until the final fight where they battle in crime ally..the place where their parents were killed.
Who should he be played by:
Scott Adkins
SECOND FILM:
Red Hood
This is not the Red Hood Version but the original version of Red Hood but he does have a cool design that is different from his original version but still staying true to the original. In this version he is James Chill brother of Joe Chill the murderer of Bruce's Parents. Batman decides to research about the man who murders his parents. James Chill is dealing with alcoholism and the possibility of having a child..it is extremely conflicted with his brother's behavior because he's a criminal.Slowly Joe convinces his brother that crime is necessary in order to live life to the fullest. Joe suggests to take on the identity of a vigilante called Red Hood, he recruits a gang inspired by clown and steals money from banks and over rich places. Red Hood clashes with Batman multiple times throughout the movie until the final battle at the ace chemicals factory. Reed Hood battles Batman but fails and falls into the chemical waste. This causes him to go completely insane and take on a new identity..The Joker
Who should he be played by:
Aaron Paul
THIRD FILM:
Joker
James Chill turns into the Joker. He kills his brother due to his new found insanity. He targets James Gordon and shoots Barbara Gordon in the back crippling her and then torturers her with a knife leaving several scars on her body and being very near to death. Joker takes James Gordon and kidnaps Bruce Wayne to his secret fun-house planning to drive them both insane. The Joker kidnaps his son Damian and makes Bruce believe his son is dead. Bruce manages to escape and put on the Bat costume. Bruce goes through the fun house but Joker nor James is not there anymore. Bruce over the next few days searches the entire city trying to find any leads that can lead him to the Joker but he finds no leads. He gets frustrated and lets out his drones that he had sealed away to find the Joker but his anger makes the Batman drones lose control and they destroying many buildings. Joker finally appears at the Wayne Mansion explaining how he is here and telling him there is nothing Batman can do to stop him..it is later revealed that that Joker was just a projection. Batman uses the tech to find the Joker where he is had his final fun house..
Who should he be played by:
Aaron Paul
