Chapter 550 summary
Around the world civilians anxiously discuss Ace's impending execution and whether Whitebeard will appear, with many fearing widespread deaths if he does. At Marineford the evacuated island hosts over 100,000 elite Marines arrayed in defense, including fifty battleships, heavy cannons, and the Shichibukai Donquixote Doflamingo, Dracule Mihawk, Gecko Moria, Boa Hancock, and Bartholomew Kuma. Ace is led in chains onto the execution platform with three hours remaining as the three admirals Kizaru, Akainu, and Aokiji sit before him. On the approaching Tri-Current Luffy spots the Gates of Justice while Jimbei and the prisoners debate how to pass them. Sengoku and Garp mount the platform, and Sengoku addresses the forces and the world to reveal Ace's hidden history. He explains how Ace's mother Portgas D. Rouge carried him for twenty months after Gol D. Roger's death to hide the child on Baterila. Sengoku declares that Ace's father was the Pirate King Gol D. Roger, sending shock through the plaza as Ace lowers his head.
