Isaiah is a 6'4 man with a well-trained and muscular body. His clothes mostly consist of a white shirt, a black suit jacket, black dress pants, gray (almost black), dress shoes, and black gloves. Isaiah has a messy hairstyle in the color of dirty blonde, followed by brown -- almost black -- eyes in the shape of siren eyes. Isaiah often speaks Russian once he is, annoyed and sometimes Greek when he tries to be sweet (He's Half Russian, a quarter Greek and a quarter British.)
