Signal in a word is, average. He is about 5' 11" which is average for a human male. He has dark brown hair that is long for a man but he usually keeps it wrapped up inter a hat or hood. His brown eyes seem to be nothing remarkable. He is a little on the thin side at 175 lbs but it really just makes him look like he was built a bit smaller. He wears rather loose fitting clothes when out of his armor, always long sleeves and pants, usually with a hoodie. On the rare occasion that he rolls up his sleeves, he can be seen to wear a black body suit as an undergarment.

His body armor is marked with crystals as is his helmet, and it has an integrated holster on the hip. A Wilks pistol usually inhabits the holster.

He is usually quiet and watches the interactions of others, rather than speak up himself. He will answer when asked and offer advice when he sees fit though.
