Don't worry, she won't even remember her name when I'm done with her.
~ Blue as he prepares to lobotomize Babydoll
Blue Jones is an officer of the Asylum and the main antagonist from the 2011 film Sucker Punch.
He was portrayed by Oscar Isaac, who also played Apocalypse in X-Men: Apocalypse.
Blue, from the girl's point of view, is seen as a threat. He believes he holds the power within the brothel, as exemplified by his quote, "I've got everything under control". He is shown exerting his power over both Madame Gorski and the girls.
After observing the girls changing behavior as a result of Babydoll's presence, Blue begins to become suspicious of the activities of the girls, and ultimately overhears Blondie talking about the girls' plan to escape. As a result, he directly confronts them leading to the death of both Amber and Blondie. In a fit of rage, Blue begins to advance strongly upon Baby Doll claiming that he does not want anybody to play with his "toys". However, Baby overpowers him, stabbing him with the knife that was collected from the cook, claiming that he will never have her.
Back at the asylum after Baby Doll is lobotomized, it is revealed that Blue faked Dr. Gorski's signature on the medical forms. As a way of getting revenge upon Baby for being stabbed, Blue once again attempts to advance upon her, this time crying due to Baby not being able to struggle. To get a reaction, Blue begins to strangle Baby Doll; however, before he can do any harm, police officers detain him and arrest him for forgery. As he is being taken away, he yells out about the money and claims he would tell the officers everything, although there was never really any chance he would not get caught.
Although the stepfather was the mastermind and drove the plot of sending Babydoll to the asylum, Blu had more screen-time because he did all the work, had bigger plans than anyone and was more dangerous.
Isaac starred in another movie with one of the actors, Abbie Cornish, which was released on the same year as Sucker Punch.
Originally, Babydoll was going to kill Blu when she stabbed him in the shoulder, which he survives in the finished film.
