Isaac McDougal appears to be in his mid 30's as he looks mature. He was also very muscular, average tall man, being much taller then than Alphonse Elric but still dwarfed by Alex Louis Armstrong. He had long black hair which was tied back, only for one strand to hang over his face. While trying to move throughout Central quietly, he donned a simple dull cloak, and underneath he wore his original State Alchemist uniform which was composed of an open jacket with the right sleeve torn and elongated leggings with a length of material hanging down the back.
