Plastic
Someone once said that Plastic's brain operates in pure binary code. Plastic herself scoffs at this, knowing full well that she left binary thinking behind when she was five. Now she operates on a quantum level and it's questionable whether the computers can keep up. To her they are tools through which she molds code like clay, forming and shaping it according to her whims and fancies.
Never one for social interaction, Plastic leads a hidden existence in the bowels of the city, getting by on doing jobs for everyone without claiming particular allegiance. She takes only the hardest assignments, her fee high enough that even some Corporate Houss would think twice before consulting her. But if a job intrigues her in any way she might very well do it for free, just to learn something new.
