Beckman is a tall man, standing at a height of 206 cm. Twelve years ago in Foosha Village, his hair was long, light brown (black in the anime) and pulled back in a pony tail. In the current storyline, his hair is now gray, medium-length, and slicked-back. He also now has a large, X-shaped scar on his left temple. He is never seen without his rifle nearby or a cigarette in his mouth.
His outfit has changed very little over the years since his first appearance; he now wears a black, v-neck shirt with three quarter sleeves (whereas he is previously seen wearing a short-sleeved shirt of a similar color and design) along with loose pants (originally of a dark green color, but presently gray) with numerous pockets on them, tucked inside his buckled boots. Like most of the other Red Hair Pirates, he wears a sash around his waist, to which he attaches his rifle in a pistol-like fashion. The only thing added to his attire is his spiral-patterned cloak.
