Onigumo

Vice-Admiral Onigumo (オニグモ中将, Onigumo Chūjō) was one of the five vice-admirals leading the Buster Call on Enies Lobby. He was the one who commanded three ships to attack a fellow Buster Call ship with all its 1000 fellow sailors on board just to target Luffy, who was fighting on it with Rob Lucci, though he had confidence that Lucci would survive. When a soldier argued against this order, Onigumo shot him in cold blood, saying:

"With a moment of hesitation, can you protect the future, from a criminal who is trying to escape? Fire!".

He was last seen shouting insults at the personnel of the Gate of Justice for closing it down (though in reality it was closed up by Sanji).

Onigumo is one of many enormous people in the manga; he is of similar stature to Bartholemew Kuma.
