Beckman is a tall man, standing at least a foot taller than Shanks. His hair was jet black and pulled back in a pony tail 12 years ago in Monkey D. Luffy's hometown;in the current storyline, his hair has turned gray and is cut short. He is never seen without his rifle nearby or a cigarette in his mouth.He also now has a large, X-shaped scar on his left temple.

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.
