Parker is timid, shy and suffers with anxiety and intrusive thoughts. He has a heavy interest in robotics, working at the company that made Nano (Nanotech X). He wants to build his own version of Nano, thus stalking her, but eventually realises that Nano is fine the way she is and joins their little group, starting to want to help make more prototypes like her to emotionally help people. 

Parker is always nervous, even in critical moments, and has a high pitched male voice.
