When Luffy attempts to charge the execution stand to rescue Ace, Coby blocks his path, determined to defend the Marines’ objective even if it means the execution of his friend’s brother. His resolve, however, is not enough: he is no match for the captain of the Straw Hat Pirates and is defeated with a single punch. Luffy moves on, leaving Coby unconscious in the middle of the battlefield.
— Coby tries to stop the war.
The young Marine’s cry causes a moment’s pause in the battle and inadvertently saves Luffy’s life.
Akainu, unimpressed, prepares to kill Coby for wasting precious seconds of the battle. The young Marine fearfully steels himself for death, reassuring himself that he said what he had to say and that he has no regrets.
His life is saved by the sudden arrival of Shanks, who commends the young Marine for his actions, explaining that his few seconds of courage have drastically changed the future of the world.
