Read One Piece Manga Chapter 550    

 Summary:

Southern Blue
A group of people at the local market are discussing the upcoming Seven Warlords of the Sea-Whitebeard war, claiming that Whitebeard is old and it's no big news anymore.

Eastern blue
A number of farmers are also talking about the war, saying that Whitebeard will definitely lose against the Marine Command. However, the farmer notes that it would be best for everyone if Whitebeard didn't show up and the execution went ahead as planned.

Northern Blue
The man is turned away by the bar, with the bartender saying he would open the store tomorrow if there was still a world left.

Western Blue
The man at the bar orders another drink and tells his fellow punters not to underestimate Whitebeard, he's as almighty as ever. He talks about a time when Whitebeard was in a bar and made a lot of people give up their lives just by sitting there doing nothing.

Big line
The woman notices that her children were also aware of the situation as they played with the jump rope and sang "Old Man Whitebeard, scarier than demons!". He looks up and says, "What has this world come to?"

Marineford/Sabaody Archipelago
In Marineford, where most of the Marines' families lived, the place is empty because everyone was evacuated to the Sabaody Archipelago.

On the archipelago, families monitor the situation on giant monitors that look out over Marineford. There are also cameramen and reporters who are ready to deliver the news as soon as possible. Soon the man shouts that Ace has appeared.

Back at Marineford, Ace, flanked by two executioners, kneels, ready for his fate, which is due to arrive in three hours. Marine patrol ships also head out to find Whitebeard, who is never seen again.

John the Giant is seen telling the Marines not to let their guards down. With 50 Marine warships surrounding the crescent-shaped island, walls lined with cannons, and 100,000 elite Marines, the Marines await Whitebeard. Also on the walls are 5 of the seven sea warriors who are also waiting for Whitebeard.

Sitting on the execution platform in front of Ace are three Marine Admirals, Kizaru, Aokiji, and Akainu.

Tarai Stream
The prisoner ship reached the Gate of Justice. Luffy and Jinbe start planning how to get past them. Meanwhile, Buggy is still rounding up the prisoners.

Marineford
Sengoku tells Garp that he will "tell all". Garp replies to do whatever he wants. Sengoku stands next to Ace and tells the executioners to back off.

Sengoku confronts the marines and tells them that there was something major, the real reason for Ace's execution. Sengoku asks Ace who his father was. Ace replies to Whitebeard saying that he was the only father he ever had. Sengoku then goes on to say that the Marines have been looking for the baby for years, investigating every new born baby, every baby to be born, mothers who were pregnant and little clues from Cipher Pol, but came up with nothing. However, Ace and his mother escaped this investigation: Ace's mother, Portgas D. Rouge, went to an island in South Blue and held him in her womb for 20 months. This led to her passing when Ace was born.

Sengoku then states that a year and three months after his father's death, a child with the "most cursed blood" [Ace] was born. He tells Ace that he shouldn't claim he wasn't aware.

Sengoku then reveals the most shocking truth: Ace's father was none other than the late Pirate King, Gol D. Roger. Garp has a brief shot of Roger telling him to take care of the unborn child.
