Quark's costume is green and gray. Green gloves going to his mid-forearm, and dark gray boots covering to the mid-calf. A green wedge tapering to a point on his chest. Gray across the rest of the torso, and dark gray full face covering mask.

Alex outside of costume is College Professor.  Slacks, Docksiders, button down shirt (but his sleeves rolled up). A wind breaker as needed.  His clothing is new or well taken care of.  He is a research professor in residence, and teaches the odd Physics 101 at Tulane, or the occasional course on subatomic physics for the science major students.

Alex is in his late 20's, has short brown hair, green eyes. He's about 185 lbs, and 6 feet tall (most of the time).
