Screw is almost always wearing a Vacc suit, even on the rare times he is on a planet.  He's more relaxed in a zero-g environment and his sense of personal space can frustrate others, upsetting their personal bubble.  He shows a lack of personal modesty as well although he keeps confidences and respects boundary if he's told what they are.

Screw is approximately six feet in height and fairly wired without much fat.  His brown hair is cut short and his blue eyes tend to stare at things.  He's not pretty nor ugly.  There is a long scar on his neck and a crude tattoo of two bars on his right shoulder.
