"Why would I wear clothes? In case you haven't noticed, there's nothing there."

Altair is a shell, a robot-like, electronic being that was once human. Due to discomfort with the body he was born with, he went through a process of uploading his mind to a black box device that gets plugged into the shell. These shells are the most integrated into the augmented reality and virtual reality technologies of his time, and the corporation producing these "full-body prosthetics" are the most security minded of all the telcos... however this does not stop people being wary of these strange creatures.

If they can be called creatures at all.
