Vice-Admiral Onigumo was one of five vice-admirals who led the Buster Call operation on Enies Lobby. A tall, imposing figure with a perpetually stern expression and closed eyes, he's typically seen smoking and wearing an archaic war helmet with long hair flowing out from beneath it.
Onigumo's defining trait is his unwavering belief in Absolute Justice—so absolute, in fact, that he's willing to sacrifice anything to achieve it, including his own allies. When a soldier under his command objected to destroying a fellow Buster Call ship and killing a thousand Marines just to get at Monkey D. Luffy, Onigumo didn't hesitate: he shot the man dead on the spot for questioning the doctrine. As a Marine vice-admiral, he had the authority to command an entire Buster Call operation alongside four peers, giving him significant power within the organization.
