Lumen stands exactly 6 feet tall and weighs 200 lbs to the ounce. His entire existence is a tribute to the wonders of engineering and a paean to the thinking mind. Broad of shoulder and mild in temperament his crystalline blue eyes peer out with an unquenchable curiosity, mirrors unto an intellect that is as tightly wound and finely ordered as a pocket watch. Lumen's integrated armor plating is polished to a mirror shine. He favours a shield in combat.
